Everything runs on smoke, let the smoke out, it stops running....

Send it back, it hasn't got the thing for removing stones from horses hooves.
Tom... :o
The blue ringed one i find  particularly useful though, it is the necessary tool for defusing a suitcase nuke or removing the stones from a horses removing. Whichever is more likely.

Ahh I must get one..... :o :o

I have never seen a suitcase nuke. if it is so common that you need tools for them down-under, perhaps i will stay right here. ;)  :o

We have many animals with pouches, small suitcase nuke, exploding Koala, very dangerous and could be in any gumtree, ready to drop.  :o :o :o

LOL, i have heard a koala at the zoo. sounds vicious enough! i can't imagine worrying about what is in the pouch.  :o

I'd heard that drop bears are dangerous, but I didn't realise that they carried nuke suitcases.
An Arduino Geiger counter might be useful.

Ahh yes, I love the sound of falling drop bears on an April morning!!!!!!

Hi,

Once they get into the Jack-Daniels they are uncontrollable.

Just arrived in mail today, 3 of THESE. (16-channel relay module) a few days back, with the intention of creating a complete CNC/Radio camper automation system. the idea kinda faded due to writers block, but i may still make it. not sure why i needed 48 relay channels, but if i don't use them all, it may come in handy in the future. they were only about $10 each.

i will probably use some shift registers (74HC595) to reduce the needed Arduino pins. i ordered some quite a while back after reading Nick's tutorial, but never got around to experimenting with them.



not my soldering work, but the clean-up of theirs could have been better...

Hi,
The PCB doesn't look as though its been cleaned with anything decent, even isopropyl does a better job with a toothbrush.
For a start it looked like bits of paper towel had been caught on the wire ends,

Tom.. :)

I will try the toothbrush and alcohol later.

right now i am elbow deep in debugging a library i am trying to write for my RFID reader.

Those look like hairline traces to me. If the board was bare, I'd say it's time to go for smoke! Put a few amps of 12V through those and pffffttt, those glitches be gone! But with a populated board that'd be real stupid.....

Use a tip on a small cutter or a razor to cut all those hairline bridges on the top part of that board. That board looks very REJECT but cleaned up will probably work just fine.

My Z-80 machine had a worse mobo, it only worked when it was twisted a bit. It got put on "customized" standoffs that kept it twisted enough to run like a champ. Hey, I got it for less than half price and it did run.

ATTiny10 from Digikey (30 cents each, they were more expensive on eBay and Aliexpress), tiny piezo, some tiny button batteries, and a SOT23 breakout for one to experiment.

My plan is to sandwich the battery between piezo and ATTiny10, solder em all deadbug, use piece of paper on battery contact to keep it powered off until I am ready. The code will wait some minutes before making noise.

Pull paper tab, drop it in discreet places, walk away.
