Hackaday: Cheap Helping Hands

We think of helping hands as those little alligator clips on a metal stand. They are cheap and fall over, so we tend to buy them and don’t use them. However, if you are willing to put $35 or $40 into it, you can get the newer kind that have–well–tentacles–on a heavy base. [Archie_slap] didn’t…

Teensy 3.6 DIY Reference Board

A known good reference board for testing the MKL04 chip when building a DIY Teensy 3.6. Refer to this table for the differences between Teensy 3.6 and other models. The soldering friendly LQFP package (at least more friendly than BGA) is used on this board.

Working with Surface Mount Components and BGAs

BoardCompleteLo

Surface mount PCBs (Part 1) If you look at a circuit board today, you’ll see a beautiful array of surface mount chips and components, including very fine 0.5mm or even 0.4mm leaded devices and BGAs. Some of these ‘exotic’ devices can contain really advanced technology such as high speed ARM microprocessors, flash and high capacity […]
