Blood Electrifier Problem???   Message List

Re: Blood Electrifier Problem???

Thanks Chuck for the recommendation. I took it! 

I purchased a second 3 1/4 X 2 1/8 inch breadboard and cut it in half with a hack saw.  I unsoldered and removed the components from the printed circuit boards and transferred them to the breadboards. I now have four functioning blood electrifier circuits. I'm not sure why the little IC circuit boards were not working??? I didn't have a hot-melt glue gun, but I did have a tube of clear silicon sealer and that seemed to work quite well to encapsulate the components on the board.

I have been zapping my blood for three days now and my unit is functioning flawlessly.

Take Care,
Steffan

It seems your board is bad.

The small Vector boards used for breadboarding are neat.
You could set up your circuit, check it, then encapsulate it with hot
glue sticks as a possible solution.

Check you solder connections closely sometimes a solder connection will become intermittent. Are you using a circuit board? Jack ... From: twotower61 To:...

Wow that's pretty much what I would have done. Using a magnifying glass did you look for a hairline crack in the pc board? No chance there is a solder...
