Creating a Second Factor Authentication Token
Today I learned all about the many different methods of pad repair! After watching a couple videos, I came to the realization that basically, people do whatever they can to make the pad work again. YouTube Videos Watched: “PCB Solder Pad Repair & Corrosion Clean Up- the Epoxy Method”- https://www.youtube.com/watch?v=vx50YtEC2S8 “Silver Conductive Pen- DIY PCB Trace …
Today I worked on the blog, helped rearrange the office, opened up all our beautiful PCBs (https://blog.redkeyu2f.com/2018/07/05/u2f-token-building-the-pcbs-arrive/), and started learning about reflow ovens. Now that all our parts are here, we have to learn how to properly use our toaster oven to solder our boards. Apparently there’s quite a bit of technique to this- good …
We first stumbled across KiCad when looking to modify PCB components before sending the boards in for manufacturing. We learned that to modify the PCB, we had to modify the Gerber files, and to do that, you should use KiCad. This was a bit of a snag in our plan as none of use knew …
Today I spent the whole day doing hands-on work. I took all the parts I’d harvested from hours of desoldering, and learned how to identify and test all of them with a multimeter. Before I actually got started, I got to watch my boss test them and he gave me tips on what to look …
Today I sat and learned a whole bunch from my employers. We talked about different jobs, how other employers act, money, and a whole lot of other stuff. Then, I set off to try and clear the fog that learning about electronic components had put on my brain. Just watching videos wasn’t working, so luckily …
We found all the parts needed to build a simple U2F security token thanks to Github. Here’s the link: https://github.com/conorpp/u2f-zero/wiki/Parts-List Basically there are 8 components per token. All should be surface mount parts. Here’s what you need: PART MANUFACTURER PART NUMBER PRICE PER WHERE TO FIND Microcontroller EFM8UB11F16G-C-QSOP24 $1.38 https://www.digikey.com/ Secure Element (Authentication chip) ATECC508A-SSHDA-B $0.75 …
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 …
