Nice little project. While I agree that sloppy is easier my worry is that a clipped-off lead will flang over and drop through the vent slot in a scope or something I'm working on (my luck). So I hang on to leads when I clip them - then I drop them on the floor! Regards, David
The object when trimming leads is to try to hit your coworkers. 🤪 Seriously, though, I always have to double check what I'm working on to make sure one doesn't go off and hide somewhere only to short out ICs that have been discontinued for decades. (Preparing coax cable for crimp terminals is another thing that scares the hell out of me--silver plated copper fuzz *everywhere*.)
Fun enough. Shop tip: If the cut off pins are ferrous, a rolling magnetic shop bar broom may be helpful. See Harbor Freight Tools/etc. If you still keep cars in the garage, I would be somewhat concerned about getting a pin in a tire.

Nice object, maybe you can try to hit individual tones with little balls of paper out of a blowpipe. I remember when I bought my first semiconductor laser when the price has gone down to 500 $.
Fun little kit. What is the stressful electronic project you were working on? You know you aren't allowed to do anything electronic without sharing it with us 😁
It’s the LEET video :) Congrats! Delightful content, as always. Chill and happy. If I was doing the firmware, I’d generate all the tones and multiply them by the “relative darkness” on the photo resistors. Alignment would amount to making the thing quiet. Then polyphony is free, dynamics are available, and the firmware doesn’t need to decide where a note starts and ends. The firmware on that thing is pretty slow in scanning the inputs and/or deciding when to start a note. It can take some cleverness to make it work that way. Or just sidestep the problem completely. Also: with good old 556 tone sources, the CPU wouldn’t be necessary, and you could actually tune the thing, just like a real harp! Add a couple 4066 switches and you can even have a pedal switch to move between two tunings. But without the CPU there’s no cheap way to have it play a preprogrammed tune. So as always: trade offs.
I got an earlier version of this, (I pressume it was V1.0), ages ago. The PCB refused to take solder and some of the pads just fell off as soon as the iron touched them. :(
Nice ! better than some of the 'musical' kits you can buy...cheers.

It is like what the Big Guy From France played during Rendezvous Huston event but much much bigger.
yeah, that song is

WHAT? It don't play cords? What junk! Only kidding. Good video. Something fun to fiddle with.

@@IMSAIGuy Thanks---i did watch it and you're right---I don't envy how fiddly that project was.
Wow that's wonderful.
I think you nearly started to play any piece of note at the end 👍

Did you get it going though ? 😃
@@andymouse Unfortunately not. But I did make some of my own laser projects that kept the cat entertained. LOL.
