Hello everyone!!!
I've been repairing things for many years now and especially in the last 3 or so years blown caps (in computers/monitors/etc) have seemed to increase. I'm getting more and more computers that have silly blown caps in them!
Well... normally they are in parallel and if I end up replacing them, and then testing the computer only to find out something else is damaged too... then I loose those caps that I put on. (I never like to remove them because re-using them too many times will cause them to damage.)
SO! I thought I would make a Electrolytic Decade Capacitor in order to set the value, and solder on a couple/few wires to the board and then test it before I waste caps just to find out its still broken.
I wanted to share this idea with you all and also show pictures of my project. All together it was only about $5.00 or so.
(I used salvaged caps and scrap wire! New caps and wire might make the cost higher but I'd imagine still be under $10 or at least under $15)
Anyway!!! So far I'm loving it, and its a great tool to have! ^__^
The cable (last picture) is so that I can plug in my oscilloscope to the project/tests as a bonus! I also have a "normal" screw terminal plug (a old 75/300 ohm converter that I removed the coil from.)
PS: My cap tester is a cheap crap one but it works pretty good for higher values. (under uF its really off) And I did not yet add the "discharge" resistor to the project yet, I wanted to get some opinions and do some math before just adding any old resistor to it, lol.
