Wait, did you try this...
Ah, all my part definitions are obsolete AGAIN? I feel so surprised.
{Gives LM555 to snuggle with}
"one wire" Dallas, it uses 2 wires..
Static go BZZZT on your SSD. I dont miss that.
Well, it contains text messages in 5 languages (atleast) containing names of the months and 2 digit numbers from 00 to 59.. I have seen systems where all the user software is just config script.
Check out the offset tho, whats with that...
I tried a few tools and completely failed to be able to get them to id the processor.

2018: wall pencil holder. I think this is posted on thingiverse...
huh, I guess the CH32V003 is fast enough to do on-the-fly i2c address remapping.... drat, I wanted to use a CPLD....
ok, the image is odd, its got a huge 0xEA header, but I do see what looks like it could be a vector table...

(note the "3C" followed by 2 bytes, then repeating) 5 vectors.

I wonder if this memory is mapped funny.
THIS is the ROM from a newer model nortel digital phone. would anyone like to guess what processor the firmware on it will be for?
HOLY WIND STORMS THERE ARE TREES BREAKING EVERYWHERE!

(says the guy in canada)
Oh wait, if its kiwa then he metered the contacts and its actaully the switch. .... contact cleaner...
Contact cleaner spray, one you give it to a switch, its addicted for life. But I think the problem is the pullup resistor.
Well, I have an aplle II, should I put it on discs for anyone?

here's the schematic, it's exactly the same as the model 1's onboard design, just duplicates it for each channel instead of mixing them down to mono.

whole thing fits comfortably into a 23mm x 13mm (0.9in x 0.5in) board if you can do smt soldering.

i can't offer tech support, but have fun 💜

Medidor de corriente, frecuencia de red y potencia no invasivo

En esta entrada veremos como medir la corriente la frecuencia y la potencia con un sensor de corriente no invasivo SCT-13-50, un amplificador dual LM358.
When you hit enter and everything actually works, the way you wanted it to.
cool, I'd be curious to see a photo log of the takedown!

my *unfinished* but working, constant current load. I have an arduino on there to set currents and record voltages. I have used it for battery testing and AC adapter load profiles.
I wonder what the pressure was...
pff, I'm not a sportsfan and even I know its got something to do with baseball.
