Hackaday - Modern surface mount components often need special tools for rework However, those tools can be expensive Michael Skrepsky wanted an infrared rework station, but didn t like the price So he built his own According to Michael he used a lot of scrap in the construction He used K-type thermocouples, optotriacs, triacs, a 20 4 display and, of course, an Arduino An old bathroom heater, along with a 600W and 100W halogen bulb work as heaters The Arduino runs two PIDs One is a slow regulator for preheating The other is an interrupt-driven phase regulator for the top heater Michael built the circuit on read more http://www.secuobs.com/revue/news/602960.shtmlhttp://www.secuobs.com/revue/news/602960.shtml Secuobs.com : 2016-04-06 01:15:27 - Hackaday - buildxyz had no opposition to his kids playing video games, but wanted something that offered a bit more parental control, a larger game selection, and was maybe a little more contained than a modern game console So, in his multi-part build log, he goes through all the steps of making a Raspberry Pi into a kid friendly wall-mounted game console The frame is made from Baltic Birch plywood, and the edges look cool when stained The display is an old HP monitor, and the speakers are simple beige bricks from the thrift store The controllers hook into a USB hub read more http://www.secuobs.com/revue/news/602942.shtmlhttp://www.secuobs.com/revue/news/602942.shtml
