Battery Power Protection and Regulation PCB

Design of a power management board in Altium.

Needing various power rails off a 4-cell LiPo battery pack, I designed a PCB with overcurrent/undervoltage protection and 8.4V/7.4/5V buck regulators.


ESP8266 Sous Vide Controller

Immersing food in a temperature controlled water bath.

By separating the internal and external cooking procedures, a perfect steak with no internal temperature gradient can be easily achieved. Cooking sous vide provides reliable, consistent, and precise results every time. An ESP8266 wifi chip was used to monitor and maintain the temperature controlled water.


Adjustable Portable Power Supply

Providing power to the people. Or in this case, hobby projects.

Tired of using a spliced USB cable or combining batteries to achieve a desired voltage, an inexpensive boost-buck converter was paired with the input from a laptop power brick to supply variable voltage.
