Comments:
Hi Brett I have been unable to open the info on the Voltmeter Clock, I have built the basic clock but now would like to change it to reflect the synchronization that you have done.

What I was after was the coding for the PIC.

I have just successfully got my ex GPO 30 sec clock running with an Arduino nano and a DS3231 supplying 1 sec pulses counting 30 then pulsing the clock.

Hi Brett! I have made progress in my ambition to create a copy of your DCF77 Analyzer.
The compilation now also works for TFT Analyzer v26 while "Serial monitor v9" does not want to go through the compiling In the error message,
 which comes from Adafruit_GFX_AS.cpp with stops on several lines, 138,145, ... to 272, the message text "textsize was not declared"
Where should I place this declaration and what value?

Hi Lars I have checked the code and it complies fine on my setup.
I would check the

The buzzer plays during the Simon and Tetris games.
If you look at the video "Demo Video showing Clock functions" at around 1 min 30 seconds you will hear the buzzer play.

Which of my web sites are your comments referring to?  1 second slave clock

Comments:
Hi Brett, exhibits on the site are most impressive.
 I'm looking for 1-second mechanical slave clock (second sweep hand only is OK) driven by a PO36 master clock, voltages could be anything from 3-20vdc via a relay, pulse would be 200-300ms.
The movements that I have eg Gent & Synchronome are all 30 second (120 teeth) so a 1-second pulse would only complete a 180 deg/half a revolution in one minute.
 It would be a novelty I suppose to display 60 seconds in a 180 deg quadrant provided the face is printed appropriately but that's not what I had in mind.
Do you have any thoughts please as to how to achieve this? Many thanks in advance.


Reply: Michael I have emailed you some ideas that I have used on PO36s before.

Comments:
Dear Brett,
First of all my sincere compliments regarding the Arduino Barometer.
For your information, I am a true Novice in the field of electronics and microcomputers, therefore all my apologies in advance for the questions asked in a learning moment, this questions will not seem too smart to someone knowledgeable.
Finally I have a mill working reasonably well and my next challenge is to mill a round PCB for the Arduino Barometer.
Probably a bit too high but I can see where and when the project gets stuck.
That is why I am now transferring the scheme to a drawing program (another new challenge) with which I hope that I will be able to convert this into a grbl file for the milling machine.

My question regarding your schematic:
Arduino Nano, R13 should this be a 10K resistor instead of the 270O?
 
Also my instinct says that the switch “Step Fwd SW7” is connected on the wrong side of the R13 resistor because when closed there is developed a short circuit?
 Is my reasoning correct?

Atmega328, Pin # 21 Aref, is this pin connected to “something”?

Last question, if there are any questions purely and of course concerning this Arduino Barometer, do you mind if I approach you again. I am very curious about your response and best regards,

Jan Bouma

In the schematic of the Arduino DCF77 Analyzer Clock MK2 did you install some diodes on the mainboard, D3, D4, D6 and D15.

What diodes are they because I can't find a label.

Thank you very much.
Benny


Reply.


D3, D4, D6 and D15 are all conventional diodes not LEDs and are all shown on the schematic.


D3 and D6 are part of the reset circuit on the DCF77 Arduino and also the Super Filter Arduino.

See pin 1 on both ICs.


D4 is a reverse protection diode and is just after the main fuse.


Note the supply is adjusted so that 5v appears after the diode. This can be left out if not required with the supply set to 5v.


D15  is connected off pin 7 IC4 JQ9500b via R19 and also connected to the DCF77 Analyzer Arduino pn 11.


If you use an Audio FX sound board then this will not be required.

Which of my web sites are your comments referring to?  DCF77 CLOCKS


Comments:
Hello Brett You might be interested in the results of trying to distribute the DCF77 synthesised and raw output from Universal Solder DCF77 receiver.
Initial trials with small RF (868-MHz) telemetry modules were OK, but the transmitted 100-mS pulses were coming up short (70-Ms).
The 200-mS were better but not great. Something was being lost in transmission. I had some old XBee Series 1 modules (now obsolete) that have a unique feature called line passing.
The transmitter has a digital input pin (one of several) that can be mapped to the same pin on the receiving XBee (set as digital output).
The results using the synthesised DCF77 output were very good. 200-mS pulses were better than 199-mS and 100-mS better than 99-mS.

The Xbees have a good range in the 2.4-GHz channels, plus have built in security and do not suffer from interference. The downside is that Series 1 is no longer available.
The good news is that the new Series 3 XBees can use the same firmware as Series 1, so line passing is available again.
Throw in a Python SoC, Bluetooth, over air updates and this looks to be the way to go if you can't cable everything.
 I did install CAT5e over the house for LAN and also for 1-Wire (Maxim), so cabling is still an option (using unused pairs of the LAN cable), but the portability of wireless is very tempting.
I will be using your LCD master clock to build on. Another tip. I don't use the LCD I2C libraries that are generally used.
There are too many conflicting libraries of the same name. A far better library is Bill Perry's hd44780 comprehensive LCD library.
Bill Perry is as thorough as Udo Klein. One question. I looked at the Udo Klein MSF "over the horizon" link but couldn't see how to use it.

Does it support MSF60 filtering etc. like the DCF77?


Phil S


Phil try this link for MSF60   https://github.com/udoklein/dcf77/pull/9/commits/0650dd756f1ed14c2ff597da656713f071bd642f

Which of my web sites are your comments referring to?  Analyser Clock
Comments:
Hello Accurate time is a bit of an obsession with me. I have a house full of timers, programmers etc., none of which keep any reasonable time. I tried out GPS to start with using the Arduino and UBlox 6.

This works well provided the antenna is outside (too much foil insulation in my house) To get round this, I put the receiver on the garage roof, connected the output to a Series 2 XBee

 in transparent mode paired to another in the house, and it works really well. I'm on the south coast and wanted to try out MSF. Several cheap MSF clocks seem to work well, but hacking them to get at

 the signal was a bit of a faff and I ended up hacking the alarm output with a view to using that to correct an Arduino/RTC/TimeLib setup. None of the commercial MSF receivers/decoders worked and I

ended up trying to put my own together using Jonathon Hare's tutorials. Again, nothing worked. I realise now it might have been due to trying it in a house full of power supplies and computers.

Then I got hold of some Universal Solder MSF60 and DCF77 modules and hey presto, I got some encouraging data. The MSF was fussy about location, but the DCF was better.

I got the Jarkman libray going (the Phil Morris/Peter Balcombe variations), but I was still tied to where the clock would run with a decent signal. What I really wanted to was have a master clock

 and use wireless to redistribute the MSF raw signal round the house. This didn't work very well as the radios (RF Solutions ZPT plus 868-mHz) coped with the 300 and 200-mS pulses,

but reduced the 100-mS pulse to 60 or 70-mS. Then having read your outstanding Analyser Clock item, I decided to give the Super Filter a go. After a lot of messing about putting crystals on Uno’s,

getting the signal the right way round, and being patient, the Super Filter locked onto the DCF signal and is showing filter synchronised. Next step was to try it with the RF Solutions radios,

despite the iffy 100-mS pulses. But, to my surprise, after about 6-minutes, the filter locked on and at the synthesised signal output, I get a lovely pulse train. So this now opens up the possibility

of putting the DCF receiver in a good spot and wirelessly distributing the signal to slave clocks that can use accurate time to run programmers and timers. I am proposing to put my own devices together

and get rid of the inaccurate commercial (Honeywell, Danfoss etc.,) over-complicated, expensive boiler programmers and room thermostats. The Udo Klein Super Filter is a remarkable piece of work.

I wonder if it could be adapted to MSF? I liked the adaptations of the industrial clocks and am on the lookout for something similar. The last office I worked in used to have a Gents master/slave clock system

and the master was kept in the lab/workshop where I worked . It wasn’t used by then and was just decorative. It disappeared one night and I am certain about who took it.

 

Thanks again for all the hard work that went into the article and the physical clocks.

Comments:
Hello Brett, hope you're doing well. If this message ever gets to you, I would be really grateful if you could help me out with the Pet Feeder you have on your website and Instructables.

I've took a look into it and by far it's the most "professional" pet feeder I've ever seen, well done.
I'm ordering the parts because I'm trying to replicate your project for my dog since I spent a big chunk of my day out of home and he really misses hearing our voice and food at regular times.

Well, to the reason I've sent you this email...

I will be honest, I'm no expert and I'm really, really new to DYI and Arduino, it got my attention because I really like IoT so wanted to give it a try since your project although nice looks very simple to put together as you mentioned.
I'm planning on not doing the fuse box because I won't be using video at all (have a dedicated camera to monitor puppy), but I'm having some hard time figuring out where all the wiring goes.
I noticed you uploaded the schematic for the electronics, but since I'm no expert, I can barely read it and understand where the wires go.
I saw you used a veroboard for making the connections and I was thinking if I could use a protoboard instead since I have no skills with soldering (although I can manage if no other way).
I see there are capacitors and resistors on the veroboard for the ESP8266 but I don't know where I need to connect them to? I see the strips on the schematic but don't know exactly where they go :(...
Also, your ESP8266 seems to be different from the one I was looking, although both are the same model, take a look (https://produto.mercadolivre.com.br/MLB-867660518-modulo-wi-fi-esp8266-esp-01-_JM?quantity=1). Is there another version with side pins?
 I believe this one from the link are meant for using directly as a shield in arduino.

Also, If I'm not going to use that back fusebox (you mentioned it was because you powered the project from your 12v power supply), where do I need to connect the power cable?
Does it need to come directly from the wall mounted power module? I intend to use that path, so skipping the fuse box since 250mA seems pretty safe.
What power module do you suggest?
Anyways, if you can shed a bit of light on the schematics, it would be really cool. I don't want to mess anything up because where I live I cannot find that stepper motor easily (needed to import it from Germany).
So, whatever I can do to make this work on the first shot, it would be really nice.

Thanks in advance and congrats on the project again, pretty cool.

Regards, Eduardo

Hi. I am very impressed with your new MK2 clock and really appreciate you sharing it, thanks.
However, I was curious about a couple of things:

 I wondered why on the RTC module, you didn't use a rechargeable battery?

The signal to the Superfilter IC from the DCF77 module is normally low going high (non inverted) and this signal via a switch is also fed to the analyser microprocessor.

However when the switch is in the position to link the superfilter synthesized signal, it appears to be inverted data from the superfilter ??

Thanks

Reply
There is a small risk of fire with rechargeable batteries and with some questions being asked online about the charging circuit on these modules I though it better to remove the charging circuit and use a non rechargeable battery instead.

In the Super Filter code line 32 "const uint8_t dcf77_inverted_samples = 0;" you can select if you are receiving inverted samples. I have this set to "0". With this setting I found that I had to use the "Inverted Synthesized" output.
I have left the non inverted output pin as well. Just use whatever works with your module.

Hi Brent, You have some really inspiring clock designs on your site! I plan to make a mix using your Arduino DCF77 Analyzer Clock MK2 and Erik de Ruiter's one and build it in a flightcase.

Then I will scrounge 2nd hand shops for a vintage round clock to built a classic one.

One small question in your redesign of the SuperFilter, though. Am I correct in assuming that the "Signal Mon S Filter LED" (on pin 27 of the ATMega328) is the green LED in the DCF77 logo in the middle of the dial?

Thank you very much sharing your design and your design ideas with us!

Comments:
Hello, Brett. And greetings from "The Other Side" (of "the Pond", that is). Although I have seen your Voltmeter Clock (based on Alan Parekh's Multimeter Clock) on other web sites, I just found your home web site today.
I am interested in different methods of mechanically or electronically displaying time of day, and have considered for some time that I should build an analogue meter clock.
But unlike most analogue meter clocks that I have seen on the web, I would like to display proportional hours and minutes (between tick marks) instead of "digital" or incremental hours and minutes on the tick marks only.

Since I plan to give my clock an antique/retro "look-and-feel", I will probably only use two milliammeters for displaying hours and minutes (and, possibly, use them to also display month and date when the user activates a switch), since older clocks rarely displayed a seconds indicator.
In my project, I am planning on using an Arduino Nano board, instead of the PIC16F628 that you and Alan used, so some code porting will definitely be needed.
My plan is to use a periodic 2-second pulse time base instead of one of those DS1307 or DS3231 RTC modules. So I found your 30-second synchronisation method to be most interesting.
In my case, however, I plan to use the circuit board module from one of those cheap quartz clock movements. Even though it is probably not as accurate as your radio receiver time base, I reckon that the quartz clock circuit board would still be far more accurate than the Arduino's ceramic resonator.
I will, of course, need to make changes for the 2-second pulse period instead of the 30-second one in your project. (I will be using only one of the two coil outputs from the quartz clock circuit board - hence the time sync signals will be once every two seconds, instead of once per second.)

 And now for my QUESTION: Upon perusing your PICbasic code, I note that there is a "secondCounter" variable.
It appears that this variable gets set exactly the same as, and in the same places in code as, the "second" variable.
But secondCounter does not appear to be referenced anywhere (except in the assignment statements).
What is the purpose of this "secondCounter" variable?

Thank you for sharing your projects on your web page.

With best regards, "DuinoSoar"

Hi Brett, I made the pragotron clock with the tft display.
It's a wonderfull project and it works fine.
I have a problem because we in Belgium use the CET time.
Can you help me please. I can't find out what to change in the code.

Best regards and thank for your reply.

Reply
Paul search for and change this line of code
"const int8_t timezone_offset = -1; "

-1 is for the UK as we are an hour behind CET.
Set this to 0 to show CET on your clock.

Dear Brett,

I am making DCF77 Master Clock, I have a little problem, connect the Arduino circuit to the circuit that plays the sounds.

If you can kindly help me I would be grateful. Thank you for your kind reply and wishing you happy holidays, cordially Luciano Baldi.

P.S The sound circuit is identical to that of your Master Clock.

Hi Brett, thanks for the kind answer, even if the project is old I like it a lot, being a retired telephone technician I have a good pastime.

 I also built the Word Clok who speaks Italian, I await for the weekend the letters that the typographer has to give me.

The sound board is the same one that is in your project, but I do not understand how to connect it, If you can kindly help me I would be grateful to you. Kind regards Luciano Baldi

Comments:
Hello Brett, this is Tony of Rome Italy. I was really impressed by your DCF77 master clock Mk2 which really is a magnificent example of electronic craftsmanship.

 I take this occasion - if I may - to put you a simple question concerning DCF-77-locked circuits. For an amateur radio application I need a circuit that just generates a pulse at the beginning of every minute, nothing else.

Searching the web I can find dozen of circuits which do that job but all of them are overwhelmingly complex whilst I need something simple and not requiring new developments, e.g.; a Conrad DCF-77 receiver plus a small board with a PIC

or an Arduino processor plus free software.

Best for me would be to purchase an all-inclusive off-the-shelf product at an affordable price. I would be grateful to you if you would kindly suggest me the most convenient way to proceed.

Thanks a lot in advance and again congratulations for your outstanding developments. Tony

Hi Brett, Congratulations on your excellent web site and all your projects.

I'm sure they are an inspiration to a lot of people. I've had a synchronome GPO type 36 hipp mechanism clock for over 20 years. The 30 second Gents slave clock has always been too noisy for home use.

Having found your site I modified a quartz clock mechanism and built your 4093 circuit for 2 second pulses to make sure I could get that working before contacting you.

My problem is I haven't the electronics knowledge to go further. The clock has 2 contacts at the top of the pendulum wired in parallel to give a 1 second output.

These contacts could be used to ground the drive input possible through a relay to give more reliability or feed a voltage out. I would be grateful for any help or advice you could give me.

A circuit to use these 1 second contacts to feed the quartz clock movement would really be appreciated . Regard and best wishes, Richard

Hi Brett, did you know that the link to your Family History page does not work? Now that I have retired I have a lot more time to investigate my ancestry and I recall that you had a lot of detail about the Brindleys on your page.

I would be very interested in seeing it again if you can make it accessible please. I am totally confused about some of the family line and I seem to remember that it was all set out very clearly on your pages.

You kindly sent me a DVD of photos of our family and there was a soldier on there (killed in WWI) who is completely unknown to me. I couldn't find him in the census or in the military rolls for WWI.

I am going to the National Memorial Arboretum next week and I would like to see if I can find him somewhere on those(many)memorials. It would be more interesting if I knew our connection. I hope you can help with this.

Please say hello to your mum or me, I haven't seen her since Auntie Dot's funeral - a long time ago. Best wishes to all your family. Jenny

Just syncing is looks to be no problem but but I wanted to be able to auto set it after a power outage and was wondering if anyone had been there before. I have a scheme, but it would take over 15mins to reset the slave I have in mind and thus quicker to do by hand. Ideally I think I need a slave with code wheels for hour and minute hands. Hmmm.

    Master clock
Comments:
Hello I just chanced upon your website while looking for a method to drive an LCD display on a second Arduino while the other Arduino collects and processes the data from sensors around the house (run out of pins) What an impressive piece of work - the website alone is miles better than many commercial ones, let alone the content. I have been looking for an accurate timekeeper for a while now. I'm fed up with all the expensive programmers, especially on the heating systems (room thermostats, boiler programmer etc.) that as well as being expensively unreliable (on the third room thermostat (2 x Honeywell, 1x Drayton) at Ł60-70 a time, also keep lousy time, Honeywell being the worst. The plan was to replace them by Arduino based kit and send out a synchronising time signal from a master, say, once a day at midnight. I use an MSF digital clock which I hacked into the alarm function. The alarm puts out a pattern of bleeps at 00:00 which an Arduino recognises as legitimate, and then by 433-MHz wireless, puts out a pulse picked up by the secondaries. The secondaries use RTC's and the plan is to correct just the minutes or seconds with the master pulse. I tried most of the RTC chips, but all are reasonable but far from accurate over a long period. The Arduino at the MSF will only update if the MSF clock is giving a sensible time and not out of action due to signal loss (I'm further south than you) Going back to your clocks. I have a fair idea of just how much effort has gone in - it's one thing to have a tangle of wires on the prototype bench, but the hard bit is to turn it into a finished project. I find that the Arduino community falls into two camps - there are those who are very clever but refuse to give any appreciable help, even stooping to the filthy lucre game, and there are those who are clever and generous enough to share their talents. Yours are the generous variety. Very good luck with future projects and your website now has the honour of going into my "knowledge base" collection of worthwhile information Phil_S

Hi Brett Great site. Can you assist with rainfall in October 2015 please? I tried to reach via Archive, but the last one is September, so I went to the main screen and thought I had found the answer with the rainfal chart set to last 12 months. However that seems to be inaccurate at present, for I think the figure should be 100mm plus, together with similar figures for Nov and December. January looks like it will go to about 100 too. Looking at rainfal and the Bourne locally. I have groundwater figures from two monitoring places and have a chart of it all. Regards Chris

Your doorbell mod was just what I was looking for - I always seem to be in my workshop some distance from the house, when the delivery man arrives. I had all the components available in my stock other than the 556 IC - I used two 555 instead. Bought a small box to fit on the side of the DECT base-station to match and coupled with a 3.5mm jack plug/socket. It works perfectly - all DECT phones produce the paging signal and, with plenty of range, I now no longer need to keep listening out for a distant bell or revving engine.

It's always a pleasure to browse your beautiful website and thanks for sharing it with us. I remember Kenley in the late 1940's and throughout the early 1950's when my family lived at Monkswood in Abbots Lane, which is now the Acorn Lodge care home. In our garden there were large stones which must have been from the lost village of Watendone, as Monkswood was next door to where the 'new' manor had been built in about 1900 I think and our rockery consisted of huge slabs of medieval stones carefully carved. The ghost that walks Kenley was seen on numerous occasions, once in Zig Zag Road. Thank you again for your beautiful web site.

Hi Brett Very interested in your LCD master clock based on the Arduino - with some very useful code I'd like to adopt for my own 30 seconds pulse collection if that's OK? You've also cracked the chiming that I want to have as well. It's great to see how you've done it all. I was wondering how the 30 seconds pulse clocks get on with the pulse your system generates which is about a second long - rather than the 200ms-500ms you'd probably get from a mechanical GPO clock 36? Do you use the one second pulses as they are or do you shorten them in any way? My prototype arduino based set-up seems to be quite happy with 100ms pulses but doesn't have all your refinements?

Hi, Why are your nest box cams running? I went to clean my nest boxes out today and found that there are young great tits already! So that was a no go! I expect that yours will already be building or occupied!

Am interested in the light sensing setup (which I presume is not complete as it is not shown on your weather website?). Could you provide further details and information (or costs if this is something you are going to sell. Thanks

Hi I love the clocks. Mostly the Binary Slave. I do not have the skills to put one together. Is there any place I can purchase these things??

Also in the US we use a Radio Clock from Colorado. It looks like your clocks use a clock signal from Germany.

Anyway Anywhere I can purchase these cool rigs?? Jim Davison

Hi, brilliant site.  I live in Kenley and it is great to be able to check the local weather any time of day.  Although I do not understand all the dials I ike to look at the site.  The weather forecaster (weather for the following few days) seems to have disappeared over the last couple of days, will you be bringing it back.

Great Site, been using it for years.
I especially like the timelapse from the webcam.
It would be great if the quality could be improved.
It seems the images taken are clean without pixelation.
But when the timelapse is started heavy pixelation occurs.
Maybe due to the encoding settings when creating the video?
Really love the layout and comprehensive data.
Many Thanks :-)

Thanks for taking time to comment Chris.

My weather cam is uploaded to Weather underground who store the images and create the time lapse. It looks like they use very heavy compression when storing the images so the playback is very pixelated.

Great photos of the area, I used to live in Valley Road from 1965 to 1975(close to where some of the photo`s were taken) with my parents, I can remember walking up to Riddlesdown High School in all that bad weather in the 60`s/70`s.

Great website which I have watched for several years from nearby and when abroad for weather on return.

 Just noticed recently a few minor errors in weather symbol and today the temp indicator seems

 to have failed. Keep up the good work, we love it !

Hi David. Thanks for the comment. The temp sender failed last night when it was too dark to repair it.

The temp sensor is now working again.

The weather symbol forecasts are generated by the weather station and are only a rough guide to the weather over the next day.

Congratulations for your excellent site. My Grandfather was Pte. Howard Vincent DUFFIELD (b.1895), #730060, 1st Canadian Division, 1st Brigade, 4th Battalion, 1st "A" Coy (from the 111th Battalion) who fought at the; Battles of Vimy Ridge (on 9-12 Apr 1917), Passchendaele (on 6-10 Nov 1917) and 2nd Arras (26 Aug - 3 Sep 1918). He was wounded by shrapnel during the push to the Buissy Switch, in the early hours of the 3rd of September, 1918 and evacuated to the field hospital. He was first transferred to No. 1 C.O.R.D and sent to (Suffolk Hospital, Bury St. Edmunds), next to Colchester General Military Hospital and finally to the Princess Patricia Canadian Red Cross Hospital (Gordon Camp, Boxhill) for treatment. Discharged from treatment on 18 Oct 1918 and posted to the 3rd Canadian Reserve Battalion (at Witley). Shipped back to Canada on 12 Dec 1918, then reported to No. 1 District Depot (London Ontario) and was honourably discharged on 24 Jan 1919. He was a moulder and house painter by trade and married Clara Maud; daughter of Pte. Thomas George BOTTERILL, #238110, 8th Regiment Battalion (from the 204th Battalion) on 5 Oct 1920 and had 5 children. He enlisted again on 2 Aug 1940 (during WWII) and was posted with the Ontario Home Guard Unit (he would escort German POWs from New York City or Halifax to a Ontario POW Camp, amoung other duties) and was honourably discharged on 21 Jul 1945. He passed away in Toronto, Ontario on 16 Jan 1971 and is buried in the Pine Hills Cemetery (Veteran's Section), Toronto, Ontario. Keith

Great to see your research, not only was my relative (Roy Kallar) with your relative in the 83rd overseas--they attested on the same day (papers signed by same men) in Toronto, and took same voyage on the Olympic...so safe to say they knew each other. He was my great-grandfather. The difference was, the 83rd was broken up once overseas to supply units, so mine went to the 4th Canadian Mounted rifles and yours went to the 3rd Please let me know if you uncover any group photos prior to the Olympic's arrival in Liverpool...of the 83rd in Ontario All the best, Matt Parker PS..My relative Roy Kallar is on 4cmr.com

Hi, have looked at your website before and have visited it again today. Lots of interesting snippets of information. We have, this year, set up our own bluetit blog as it is the first time we have had a pair of bluetits nesting in the box with the camera. We have had 3 previous broods of bluetits in previous years but not with a camera. It has been very interesting to see it as it happens as in the past we have followed other websites to help us imagine what stage our chicks were at. The special part this year was to actually witness all 7 of our chicks leaving the nest. Our bluetit blog can be found at www.goodallweb.com/bluetits Will visit this website again in the future.

Very interesting site, Brett. I've been looking for a circuit to drive a pre-war Gledhill-Brook "electrically propelled" (i.e. 30s impulse)time recorder, and your project has given me some excellent ideas (though mine will be much, much less eleborate!). Regards, Nick.

Hi Brett, been reading you clock pages, very interesting. My interest started off with a 1932 Gillet and Johnston master clock and several slaves, but was too noisy for the house (30 sec clunk!) pendulum drive altered to magnetic, now silent. Added hourly chime along similar lines to yours. work ok but found a cct on a site electronicsforu.com hourly chime generator. Very simple and uses a clever way of doing an and gate (2 diodes and a 180K) I,ve been using this type of and gate on binary counters, much simpler than the usual way. If you cant find the site, email me and I,ll attach the diagram and description. Regards Peter
