Creating a Second Factor Authentication Token
Today I attempted to remove the faulty parts from our finished PCBs. This proved to be a lot harder to do without tearing off a pad than expected. Every technique I tried would rip at least 1 pad off of the LED’s spot. The capacitor on the other hand, was smooth sailing every time. To …
Definitions: Multimeter- a device used to measure voltage, current, or resistance. Voltage- a measurement of the electric field potential to create a current in a conductor. Current- a measurement of how much charge moves through a circuit during a specific period of time. Resistance- how freely electrons can flow through materials because of a voltage …
Today our package from http://dirtypcbs.com/store/pcbs arrived! We ordered a +/- 10 protopack of a design we knew should work, as well as a protopack that I had updated the Gerber files on and resubmitted. We had NO idea if these would turn out at all, but they look perfect. Here’s the package the 22 PCBs came in …
Today I spent the first half of the day putting together an fm radio kit. It comes with all the components needed (minus some good, solid instructions), and you just have to solder the electronics in. Here are some pictures of before and during this project process: However, when I finally finished, I realized that …
Learning to desolder takes a lot of time. The first time I tried, it took me almost 30 minutes just to remove 1 component! There’s a lot of technique involved, so every night I try to practice on old circuit boards. When I think I have this under control, I’ll move on to soldering small …
