DIY 35mm Electronics Question

[pd330]

So I'm currently building a spinning 35mm adapter for my hv30. However, the first time I tried soldering the electronics together, the batteries were leaking once i tried to see if it worked and overall, I don't know if I put it together right.

So basically the electronics configuration is: Battery pack (2 AA's)> toggle switch> motor> LED> battery pack

so if anyone here knows how to correctly comlete the circuitry without the batteries melting, please tell me :smile:

That should work, I'm not sure why the batteries would leak. The batteries are in a holder, right?

 

[pd330]

yes it was....but it could've just been bad batteries. I just didn't know if people who made adapters like this used a circuit board or something instead of just soldering some wires together

 

[edinc90]

I haven't made one, but a circuit board isn't necessary. The batteries may have been in backwards, too. Technically you need a resistor on that LED, but everything else is just wires, nothing fancier.

the batteries were leaking

Sound like the batteries are short-circuit. You'd better check battery's holder and beware of the explosing batteries

check out this site, it has lots of useful info about 35mm adapters.

I knew for a fact that the batteries were the right way because it was working for a few weeks but then one day i saw a white powder coming out of the battery pack and opened it up to find battery acid on the inside. I also probably will try the resistor on the LED though...thanks for that bit of information :dankk2:
