If you've been around electronics for a while, you've probably noticed that components like resistors, capacitors, zener diodes and inductors come in some odd values. Looking at the chart above, there seems to be no clear rationale behind the values, but there is a pattern. 47kΩ resistors and 22μF capacitors are…
Introduction to implementing USB devices. Minimal overview of hardware and software with an example with STM32 microcontroller. Also contains an index to very detailed guides for more information.
Formlabs has recently launched the fourth edition of their flagship SLA printer line, the Form 4 . Of course, I jumped on the chance to do a teardown of the printer; I’m grateful that I was able to do the same for the Form 1 , Form 2 , and Form 3 generations. In addition to learning a lot from the process of tearing…
