Help - DIY Digital Picture Frame Answered

I was finishing up a digital picture frame for my mom for Xmas, and decided to try to solder up some buttons to the on-circuit ones, but, unfortunately, the soldered wires didn't hold, and pulled some of the printed pattern off. Now the rubber button works at less than 25% efficiency. Any way to get this working better would be appreciated, thanks.


I would also try replacing those rubber type buttons. I hate those! When they begin to fail, there's no way to recover them. Replacing them can be a headache. If you've got any old junk computers, VCRs etc., you can usually find tiny surface-mount switches. I don't recommend soldering directly to the contact pads though. Instead, use a piece of double-sided tape to stick it to the old contact. Using 30 gauge wire (wire-wrap wire), follow the path of the original pads to locate either a tinned "feed through" hole or a soldered component. Then piggyback your wire to that soldered point.

I'm not sure i understand. What kind of a switch am i looking for? And what am i looking for on the board? I found some holes on the other side of the board, under the buttons but i'm not sure if thats what i want to solder to...

I just did a quick check and found this lot of 25 switches for about $10. These are tiny enough to fit under the original button covers.

Each of the switches on your board appears to have a handy pad near the switch for one of your wires. The other wire could go to one of the holes following the switche's other trace. In this case though, you'll want to use a small scribe or screwdriver to scrape the green coating from the copper so the solder will stick.


you can rip them out of and old phone (i got a ton from a fax machine

Are there any chain stores where I could find these? I'm a bit pressed for time...

Sorry... I didn't see you reply right away... You'll have to look for a regular electronics supply (other that RS) in your area. Here, we have none. I have to rely on mail order for all components RS doesn't supply. It's always been my experience that RS never has what I need now, but everything I needed last month.

Are there any stores where i can get these? I didn't see them on the Radio Shack site, and I'm kinda running out of time...

Of course, many thanks, I appreciate the help.
