If you are trying to troubleshoot a PCB you probably don’t have the schematic and can just guess where PCB traces go, if you try to follow them manually it can be tedious as you follow vias from one side of the board to the other just to loose the trace under a chip. Sure you can probe around to try to find where the trace goes but with
By looking at this radio you would expect to tune in a great AM radio station but there is some modern electronic magic in here to allow it to play your favorite tunes from the internet. “Using the credit card sized computer, Raspberry Pi–the sky is the limit. To get the best streaming music experience for this project once you have the Raspberry Pi, use the free Linux distribution, Pi
 Yesterday we looked at an entry level DIY thermostat project. If you want to go all in with processing power and features have a look at the Open Source Android Thermostat Project. It is based around the IOIO-OTG and uses the TMP36 temperature sensor. A small custom PCB is used to hold the handful of components that make the control side of things work and you simply connect up
If your thermostat just stopped working you could go to the store and purchase a new one but why not make your own. You can add any feature you like, want to control it from your smart phone? Add an ethernet module and go for it. Want to add schedules? Add a RTC and you can program timed temperature settings to your hearts content. Want to make sure the

drez20001 built this CNC machine using plywood for most of the structure, all of the slides have been made using drawer slides. I have seen this done quite a few times, some of them are very tight and smooth. The only concern I would have is longevity but they are cheap and for a hobby machine it sure makes the price right. He is using a small rotary tool
SuperHouse shows us how to control various items around your house using your arduino microcontroller as the brain. This system uses an etherten arduino to allow it to be controlled from the internet. Some stacked relay modules that talk via I2C are used to control external devices. Once mounted in the custom case the module looks great. Sample code is provided that allows the system to work as a
