If you are soldering connections and want to protect the joints , these mini brush caps are a good size. http://www.amazon.com/DenTek-Easy-Brush-10-count-Pack/dp/B002WTCK3M/ref=sr_1_15?s=hpc&ie=UTF8&qi d=1403877800&sr=1-15&keywords=interdental+brush Too expensive to buy them for that purpose, but if you have them anyway. Used RTV on an outdoor electric fence, and indoor LED project.

I have a potentiometer that I unsoldered from an old circuit board (from a junked appliance) & I'd like to play with it in circuits on my breadboard. The potentiometer has leads bent at 90°, with holes at the top, & looks close to this picture: http://www.newoldsounds.com/images/EFF-D-ECB231.jpg The leads are spaced almost exactly 1.5 times the spacing of the holes in my breadboard, so...

I bought one of these a while back, but the manual had nothing covering how to use the hot air rework station. Is there a way of getting instructions on using it? I think several companies make the same model. https://www.amazon.com/TXINLEI-898D-Soldering-Tweezers-Desoldering/dp/B07G7BH4HY/ref=sr_1_3?keyw ords=898d&qid=1562950172&s=gateway&sr=8-3 Is that what I would use to remove a sw

I could use some feedback. I think I soldered on the right side this time. https://i.imgur.com/vTV4Qwv.jpg https://i.imgur.com/SNdSgdJ.jpg https://i.imgur.com/gLIvVCQ.png The circuit was working and I made adjustments to a pot. The pot ranged from 0 -> about 4400 ohms. I got the circuit already pre-made and it worked ok indoors. I forgot to record the resistance before I st
