Interesting stuff! If you adjusting the beat its important that you try it with a minium swing, ie so that its just going through the escapement and on a longcase clock like this its often possible as a trial to pack underneath the seat board that the movement sits on before you bend the crutch...

That's a good idea, thanks. I have a number of 8M2 smd boards I had made still in stock so quite feasible. I'm not sure of the overall timing using an HC-12 link but the input pulse lasts for 95ms and wondered if there was a way to record/check how many 1's had made it over the link in that...

I am getting confused using serin, but pleased I'm making progress with something new to me. From the basic commands it says "All processing stops until the new serial data byte is received" which I assume means that nothing happens (blocking?) until the new data is received, and a 0 doesn't...

I have just received a couple of HC-12 which are marked 30.000MHZ on the crystal and are widely regarded as off frequency fakes. The listing clearly showed T300 SC110 on the crystal. Has anyone bought any HC-12 recently which have original correct T3000 SC110 marking on the crystal? Peter

Many thanks everyone, dead right it was the N I had instead of T. As the unit it is operating is in the same room I know when it is working so hadnt attempted a handshake but think on reflection its is a good idea to improve security so thanks for the link. When I use PE6 to simulate the RX...

I have been using the HC-12 as a very simple remote for a while, works ok. However I dont understand why my variable b0 which is transmitted as a 1 becomes 6 on the receive side? I have found like others that the newer HC-12 can only be used as pairs are discussed elsewhere. When I use an older...

As part of a bigger project I want to run a stepper motor via its controller for approx 1000 turns. I intend using a hall sensor on the input shaft and count the turns. I have the stepper running at around 1000 rpm using a 4046 vco to set the pulse rate to the controller. This vco works well on...

Cannot get my head around this one! Am I right in thinking that as they are in series 600piv diodes will be suitable for use with this voltage doubler circuit with 250v output from the transformer? Thanks Peter

I see quite a few clock designs use the PPS output from a GPS module (VK15E module in stock) to replace the crystal timebase when a GPS signal is available. I'm looking for a stable accurate 1Hz signal as part of a Picaxe based clock timer but trying to decoding anything else from the module...

Trying to program the picaxe datalogger (alas bought at the old price!) from the wizard and get it to work. Read through the instructions in conjunction with the wizard but although I can set the info in the wizard (and RTC) then copy and paste it and then download it successfully to the logger...

The bridge between the tracks turned out to be a spec of sawdust, yes pics are really useful to check soldering, most examples look pretty awful! The displays are driven off different PSU's so I thought that the OLED one may have a problem but when I looked this morning the both displays are...

Thanks for the help. I have the power plugged together with 5.5/2.1mm connectors. I've found one where it disconnects the power if carefully pulled in the right direction so changed it, hopeful that may be the reboot. I've changed to Symbol Disp_out = C.4 as suggested but Its still adding...

Following on from an earlier post, to avoid any timing issues I've got this program working from a external 1Hz pulse (200ms on, 800ms off) generated by an 8M2 into Pin.C.3. The program originally "self ran" but 10k resistors from the inputs to 0v cured that and I've also got 100nf decoupling...

I want to drive an oled display from an 20M2. I thought I would be able to use the decdicated TXD pin 19 but cannot allocate it so ussuaming its not possible? Display works fine if I use C.4 Thanks

I want to display the incrementing wo as a number on a display. Ive read the info and failed, been going round in circles for ages, hope someone can help. Thanks do pause 100 inc w0 serout C.7, n2400, ( 254,1) pause 500 bintoascii w0,b23,b24,b25,b26,b27 serout C.7, N2400, (254...
