The bulk of the power is local to every box. Especially the tidal wave of current for the 10 igniters on each PadBox! However for "chip-free, logic-...

@dronebot-workshop Mac OS is just a skin over top of Linux. So I'd be looking for Linux driver mode tweaks. I haven't had to tweak Linux in seven ye...

@thrandell Sounds a bit like the Space Shuttle's computer voting!

@dronebot-workshop Could also be a bad batch of chips. Could also need to tweak the OS' driver settings for that class of device. Most have erred o...

Writing to a USB flash stick, eh. How long have you had that stick? Could you be exceeding the cell lifecycles?

So are you trying to do something like an emergency stop (e.g. if you pull the wrist-strapped plug by falling off, then the jet-ski turns off)? If s...

@pappasteve Sure it's a stepper and not a servo that requires a PWM to keep it in place?

@will If someone presses early, then their channel's current starts early. If they delay the button press, then their channel's current delays.

@will Exactly. We countdown together, but human reflexes vary. The allowed window will be from 1/2 second early to 2 seconds late. Individual butt...

@will Figuring it'll take some motorcycle or truck batteries. Good news is that it only has to source current for a few seconds a few times per hour...

@will IT depends upon how many Scouts choose to press their individual Launch buttons! The RSO & Countdown Clock enable/disable the window of ti...

My usage for math these days is in multiplying the number of rockets the local Cub Scouts can fly--and so multiplying smiles! I'm currently at ten-at...

@will Pretty much. Solenoids thrust pins into the path of the knife operated by the treadles. So the some of the frames get raised, others not. T...

Welcome! My first Arduino project was to figure out & restore a hand-built weaving loom--driven by a PC full of patterns, and an Arduino to contr...

@madmisha Well given the "Seeed" [sic] guys cannot spell their own name correctly... ;-p
