I'm working on an automatic wire stripper. Not sure if I'm going the right way, but this is the most progress I'v made in 3 months.
This is the clamp that holds back the wire while the other part rips the end off. (hopefully just the insulation)
I messed up tho, and the solenoid doesn't like not being able to fully retract, so I have to operate it on ~48VDC.
Next is to work out the stripping mechanism.

Tonight I did some decapping to work out that the chips on this inkjet printer board are 74HC4514 (the big ones, the small ones are ULN2003)

So remember that "1820-6189" -> 74HC4514

@altomare wow its totally in there too!

this is AWESOME

sorry, but... really.... I know you have a scope.

So, a while ago my consumer grade coffee machine, that I modified with wifi and converted to make tea instead, broke.
The element burned out, I'v changed the element 4 times now in its life and desire something more industrial.
I set out to find a commercial coffeemaker that I could modify. As luck would have it, one came along (I actually got it before the consumer grade unit died)
Many things about the machine need to be modified. The current item on my list is to know how full the pot is (or if its even there)
You see, the consumer grade device will not pour water everywhere if there is no pot, but the commercial one will. I have been pondering ways to fix this and might be saved by a snotload (at over $180ea this is a snotload) of load cells I just got from e-waste.
but, should I? It would have to be set up carefully so I could not mechanically shock them. heat could also be an issue.

I went to a lot of work to create this graph for using flashing leds for clock sources and need to share it with everyone.

It was a lot of work, stupidly so:

@gorplop nurse call system from a care facility.

This is a frequency sweep on the digital outputs of the voice recognition filter. It shows a nice overlap region between the high and low frequency detection.
The idea seems to be to separate voice and unvoiced sounds.
My plan is to stuff these signals into an AVR and push out the data by serial, I can try analyzing the results on a PC where there is a bit more space to work.

What if, suddenly,

__ ___ ___ _____
/ /_ ( _ ) / _ \___ /

| (_) | (_) | |_| |__) |
\___/ \___/ \___/____/

😁 I have found the IP address of the new computer I put on the network!!!

YES!...

@kiwa @gorplop
Maybe Eurythmics "whos that girl"...

@kiwa @gorplop I mean, you COULD have it stream a serial message at 1200 baud and go around with the RxD of a serial converter as well, but the music thing would be more fun.
"pop does the weasel" seems like it would be a good choice.
I'm sure you both have an electrostatic tracer wand to find it.

@kiwa @gorplop write a program to play a tune on the ps2 clock line and then hunt around with an audio probe.

@foone Why could one not make a javascript BASIC interpreter?

@foone older computer and it'd be in the bios.

we should bring back bios basic, we know there is room in there...

@foone .....huh, ok, maybe the author didn't turn out to actually need it in the end???

@foone useless_boolean will detect if the for loop never ran at all, because of the stop requirement.

@foone unless its usbC

@foone But will it ever be a supercharged 1541?

@foone no safety tho, it could break the tape
