Lenovo T530 Laptop WiFi upgrade I successfully installed an Intel Dual Band Wireless-AC 7260 wireless card by modifying the whitelist in the BIOS. I've compiled this step-by-step guide with references as I had trouble finding a similar resource online. Living in Toronto, the 2.4GHz WiFi band is over saturated and my best wireless throughput was roughly 16Mbps, now with 5GHz Wireless AC, I get an average of 700Mbps. I decided not to upgrade to the latest BIOS and to attempt the whitelist modifi…

7-segment display module

Anonymous (anonymous@undisclosed.example.com) — 2014-11-13T22:37:16+00:00

7-segment display module [Working Display] Arduino library available on Github This was one of my first doublesided and surfacemount boards. I made this board using Eagle for layout and then I used BatchPCB to manufacture the board. The board operates correctly, however, if I were to revise it, I would use a larger SMT resistor than the 0402 size. The board will be controlled via I2C from a PIC microcontroller, initially for the pressure sensor and later for other projects.

Sump pump Monitor

Anonymous (anonymous@undisclosed.example.com) — 2016-03-09T00:46:23+00:00

Sump pump Monitor My parents have a cistern and a sump pump which would be useful to have some sort of water level monitoring. In the past, we would check the cistern level with a pressure gauge calibrated in inches of water. There was a rubber squeeze bulb which which would pressurize a plastic line which fed into the cistern, and the resulting level would be shown on the gauge.
