Prop is tough

JerryA

Last night I was tired and managed to spill a glass of ice water on my PE board. http://forums.parallax.com/forums/emoticons/freaked.giffreaked I thought, well there goes that Prop, but I
set the board in front of the Air conditioner and this morning I hooked it back up to the 6v supply, and voila! it ran. Now I
don't recomend that you rush out to poor ice water on your Prop,http://forums.parallax.com/forums/emoticons/nono.gif
nono but it's nice to know that it can withstand some abuse if it has to.http://forums.parallax.com/forums/emoticons/yeah.gif
yeah

good to hear it survived, you should have been here when Paul was doing the torture tests for the datasheet.
it seems there are only a couple of easy ways to kill a prop, DC higher than 3.6v and board design issues when working with heavier loads.

I sure would have loved to be there, it would have been loads of fun......

Don't worry. Water is not a biggie for low voltages like that. Your average low power chips even manage to handle the odd beer or fifty at the bar. A once a year wash-out with boiling water is an excellent way to get em back into tip-top shape ... Occasionally having to replace a chip that is missing a leg to electrolysis.

My old Nokia survived a bath in a pint of Guinness.. washed it out with isopropyl and let it dry for a day and it's been great ever since..
It's not the water that kills them, it's the electrolysis of the PCB generally. That or a small amount of water leaking into the chip and dissolving the magic smoke.

I managed to put the Propeller to the real test, I drove over my duffle bag full of Propellers and parts there of, with my 95 Nissan Sentra, Took the whole mess to my shop, hooked them up and Presto they all worked, Including all my perriferals.

@TheWizard65:
It didn't crunch them all to smithereens? That's truly incredible! Also awesome.

A little clarification on the effects of water on low voltage circuits. The apparent immunity only applies to digital circuits. Doing this to analogue circuits will always mess with the accuracy.
