Re: Bally Solenoid Driver Test Board

I don't know what or how you're designing this device, but please keep
in mind to properly test a solenoid circuit, and a lamp circuit for
that matter, you need to apply a load that's considered normal for the
circuit.  My first bench tester simply used LEDs with a current
limiting resistor, which worked fine, or so I thought.  I had a lamp
driver once that did not work 100% in my machine, but tested perfect
on my bench.  I then realized that the SCR was working, but was weak
and under a normal load would fail.  I assume the same could happen w/
the driver transistors, so now my test bench has testers with the
proper load applied to each circuit to help weed out those pesky so-so
drivers.

just my thoughts,

As Pinpoint Electronics, I am in the process of testing a similar
board right now.  I designed it to operate like the Bally tester, but
without a lot of the complicated circuitry.  I'm planning on offering
it as a kit, to keep the cost down and allow the user the option of
enclosures, indicators, etc.  I will post again when testing is
complete.

Hey, Steve !

How about producing a lamp driver board tester, either complete or
just a PCB with the components supplied or not, as a kit ? I would buy
one if under $100. Is it possible to produce at that price point?
