Arduino library converts LCD output to VGA output
The Gadget Factory has a new Arduino library that lets you take Arduino code written for LCD displays, change 3 lines of code, and convert it to VGA output: The VGALiquidCrystal library converts sketches that will run on an HD44780 LCD display to sketches that will run on a VGA moniter. This library is derived […]
Tool update: Flux and a soldering tip dry cleaner
Flux helps solder flow better, and keeps it out of places you don’t want it. Don’t even try to solder without copious amounts of this magic goo. For the past few weeks used a freebie EDSYN FL-22 flux syringe from Farnell. 5ml is about $15 in Europe, US availability is limited. The flux showed up […]
