Relay life is usually rated for the contact life at rated currents, you're only passing signals, so not really an issue The coils (as you rightly said) are more like speakers, as long as you don't greatly exceed the coil voltage, those relays should last years.

Passing small signals is often worse, than passing currents close to 1/10th of rated current. But it looks like that he is using contacts to control onother relays, which is probably the best case.

Really amazing work! 3 things kill relays. To maximize life address all 3 and they will live for a very very long time. 1) Contact current. This is easy for many of your applications because you are mostly only conducting signals with low current. Relays that must close on high inrush (incandescent lamps or large capacitors like those found on power supply inputs) will slowly erode the contacts. Since you are driving lamps, there are a couple things you could do to improve the lifespan of your relay contacts that are responsible for the lamps. A) Change to LEDs (boring). B) Find the right sized resistor to just barely make the filiment glow then put it across the relay contacts. While your bulbs will never truely be "off" they will be preheated which will significantly reduce in rush current and preserve the relay contacts. Use big (high-power rated) resistors cuz they will get HOT. Inductive loads also cause arcing on contact OPENING and require diodes or snubbers to prevent this arcing. Make sure you have a backwards diode on each of your relay coils to arrest the coil current when the relay is de-energized. Clever trick, put a 10-ohm in series with the diode. This will cause the relay to drop out more quickly. Maybe only a few ms, but you might be able to cycle noticably faster. Optimal resistance should be 10-50% less than the coil resistance. Make sure your diodes have the cathode (stripe side) facing (+) side of relay coil. 2) Coil failure. Easy stuff like don't over-current your coils is obvious. But the parallel diode/snubber not only saves the contacts of upstream driving relays, it also reduces voltage stress on the wire insulation. This will prolong the life of the coil. You may also notice less electrical noise in your audio signals. Small value cap (

This is 100% the coolest sequencer I've ever seen. That crossfade function is like the heart of what modular synthesis is for. The idea of being able to plug anything into there and add and subtract them from each other feels like a black hole full of possibilities to get lost in. My first thought is how cool it would be to put 2 sequencers with different sequence lengths in each one. I definitely need to make a sequencer with that function.

After a lot of brainstorming, I think this can be done with 2 4016s and a 4017. In super simple terms a 4016 is 4 non-mechanical relays. In theory, you should be able to set the 2 4016s and 4017 up as an 8-step sequential switch with each 4016 input receiving the center pin of each pot. All outputs of the 4016s would then be chained together. Probably with diodes. I'll update with my findings.

I love that you built a sequencer out of relays, but I love that it's essentially relay computer memory flip flops even more!

Those relays you were beating the crap out of on the mega duck reminded me of a device we use at work to do very basic EMI testing that is basically a 24VDC relay with a mains plug attached which just stuffs 240VAC across the coil and makes the relay oscillate very aggressively. Makes a hell of a racket and always sounds like it's going to explode, but that thing's been going for about 30 years!

Haha that's fun. I've seen some videos on electromechanical buzzers which work much the same way (such as "the Dixie buzzer") - and you get different sounds at DC and AC, or even depending on the voltage IIRC. A lot of those sounds immediately stood out to me as having been used extensively in Thunderbirds and other Anderson productions.

This is some proper BBC Radiophonic Workshop stuff!

You are out doing yourself on this project! I really like the idea of boiling everything down to relays - can't wait to see beatstep pro style!!! And the music is relay, relay good tooooooo!!!!!! :)

It purrs like a dragon my friend!

At first I thought: "Nice, a sequencer - only that it's implemented using electromechanical circuitry." But when you added the contact mic output then it became an entirely new beast. This is now an electromechanical instrument. That's really unique :D. 8:21 : Hearing that relay lose its shit really cracks me up ;D. I love listening to hardware that's pushed to its physical limitations. Seriously, though: That's an electromechanical oscillator. Has anyone done a module like that before? That's incredible! I've never even thought of the idea of adding non-electronic (or not entirely electronic anyway) modules to a modular synth. This opens up so many possibilities :D. Actually, thinking about it someone's GOT to make a Floppytron module now :D. And a printertron. A modular synth consisting of mostly voltage-controlled electromechanical sound sources. That would be INSANE :D.

I must watch the entire video before making suggestions, you've usually thought of everything and beyond anyway! I'd love to visit the Museum and have a photo taken with the Megadrone :)

Superb! Really want to hear a relay based percussion box, like the guiro, but with a massive relay (like from the display cabinet) for bass drum. Different sizes of relay, mounted on different materials, some with rattles and chains hanging off, coins on the contacts? Electromechanical percussion - you'll need a quieter sequencer! Love this fella, very Delia Derbyshire

My first higher voltage experiments used digitally controlled relays and it was a massive pain cos they would stick closed or fail to close, especially as they warmed. Thank god for addressable LEDs. Damn fine work. I can't help but think the pandemic has nudged you along a bit and was pondering how far you might have come in the same time with the museum if you'd had a full schedule of gigs last year?

nice visual aid. the crunch tho mmmmm

Golly you and your toys are fun to watch.

Outstanding.

Now another idea for something weird... Make a thing that has a continuous loop of audio tape. Perhaps one record/erase head. And then playback heads for each step of a sequencer. I suspect that would be funky as heck in a low-fi analog way. I wonder if it'd be able to make some glitch/stutter noise effects?

relays sound great

This is whats been missing in the musical soundscape, clickities!

If the contacts start breaking down in the relays, I hope it sounds cool.

When the grid fails, and the chips run out...you'll be a powerful man!

does this mechanical de bouncing have a effect on the sound versus integrated circuits? those sparks (witch you can prevent by adding a 100nf or so capacitor)...the delay of the separation?
