I made a Frankenstein dynamo with the magnetic rotor from a small washer drain pump a shaded poles core, removes the cogging the gapped pump core produces, that runs into a 150cc regulator and on to the battery. Its not bad, little effort to turn it to power that system

You may want to consider having a 1/4" patch jack instead of switches. That way they can each be plugged into a mux module which could then be connected to any number of effects. 3mm or 8th inch would work too.

Apart from the CV switcheas, the other 2 switches on each challen are triggers, they will go to 2 jacks which can be used for anything examples would be kick drum and cymbal, high tom and low tom etc, If you're suggesting a jack on each channel, the panel would have to be much bigger, plus the mass of wires. Just to be clear, the connections on the back will be : clock in, clock out, CV, trigger 1, trigger 2

I've built loads of these to control the animation of LED based signage. Well done! I may actually be able to simplify the circuit for you a bit. If you use the CD4017 to switch MOSFETs which will bring the ground to the column you want active in the sequencer this negates the need for an AND gate.

As for the RF ground bit, a fairly cheap 5/8” x 6’-8’ ground rod from the hardware store is all you need. Hammer it all the way in the ground leaving about 1-2” sticking up and connect all your RF grounds to it. Done.

I've actually made something similar with a 4017 and a 555 timer. I made something of a loading gif in a wearable button. The DP led was the bit that was behind the "Loading" part which would of course flash on and off half way through the cycle. I'd completely forgotten about the decatron. What you've done here is brilliant though.

I prefer to use stainless hose clamps rather than rivets so element length adjustments can be easily made. Your method will provide a consistent, professional-looking result. For my specific need, I will use a thinner cutting blade.

I’ve cut a fair amount of aluminium with a good mitre saw with a 96t blade. I have had incidents though especially when I couldn’t clamp both sides of the cut. On two occasions the off cut end has been caught by a tooth and flown off at very high speed. Since then I’ve sacrificed some timber to cut through to act as a buffer. Cutting ali with circular saws needs a lot of thought and care.

If the power units aren't that expensive and can be programmed that would be brilliant. I'd rather like to make a BMS out of those. That way it's not reliant on running current through the other cells instead of charging the cells/banks themselves. I know BMS units work. I don't think it's a very efficient way to go about charging them right the way up. If it works out a person could charge any number of cells or banks at much higher current. I have a 10p3s battery that I built as a reliable replacement for my portable power station as it's enough to run a 400w load at 120vac without overheating. It lasts about 3 hours at that load level. As it's a 1000 watt inverter it has no trouble at all with the load and works a treat. With only a laptop plugged in it's good for about 7½ hours of runtime before it needs charging again. I've installed a few car power ports for mobile phone chargers and a car audio amplifier with speakers for a bit of entertainment. Add a car stereo head and you get a right good camping radio and music system that can change your mobile while you listen to whatever you like. The stereo head has Bluetooth and auxiliary inputs for audio as well as a USB jack to facilitate the use of a thumb drive with MP3s on it or any other format for that matter. You can even watch DVD or Blu-ray movies on some units. With the inverter you can hook any television to it and it turns into a theater in the woodlands. Since the newer LED TV's are such a low power draw on the system you can quite literally watch a film every night for a week. More if you take a mobile solar panel along. The hardest part was sourcing that many old laptop batteries that were in good enough nick to do the job as it took ages to get workable cells. Cheers for the content mate as it's quite enjoyable and I'm likely to watch the rest when I have the chance to sit for awhile.
