Hacker page by Cecelia Anne
Electrolytic capacitors are commonly known as polarized capacitors, in which the anode has more positive voltage than the cathode. They are used in filtering applications, low-pass filters, audio amplifier circuits and more. Metals such as aluminum,...

Oh the difficulty of sourcing P-MOSFET in TO-92
Hacker page by Yann Guidon / YGDES
If you follow Yet Another (Discrete) Clock, you know this project uses quite a lot of MOSFET in the easy-to-solder TO-92 package. A bit less than 500, including about 300 N-FET (BS170 or 2N7000) and the rest are P-FET (BS250).The N-FET are OK: I could...

4 Things You Need to Know About Phase Loss in Stepper Motors
Hacker page by Mark Liu
1. What is a stepper motor phase loss? The lack of phase of the stepper motor means that during the operation of the stepper motor, the current of a certain phase cannot pass normally, resulting in the failure of the phase to generate a magnetic...

Teardown time again: Woods 32555WD remote control outlet. Finding out how the channel is set (it's a little brutal)
Hacker page by mcu_nerd
As I've gotten tired (and/or lazy) about having to plug/unplug the outdoor Christmas decoration lights, I finally got an outlet that can be switched on/off via a remote. The one I got was labeled as a "Woods 32555WD, but there's no Woods logo anywhere...
