This is an Arduino tutorial on how to detect lightning from far away. In this tutorial, we will build a lightning detector using an Arduino Uno, a few resistors and some jumper wires. Most lightning detectors often cost too much for the normal hobbyist, however this does not mean one...
Continue ReadingAutoResetRRR – Automatically reset routers/cameras/servers
"bogdan" published a new project, a device able to automatically reset your router, camera or server. AutoResetRRR is a kind electronic frustration reducing device: it cuts the power periodically to devices that can go nuts (routers, net cams, servers), but it does give a heads up....

Marko Pavlin has published a USB to RS485 converter. He writes: Testing of sensors with RS485 using PC without proper interface is not possible. Since RS232 interfaces are very rare, the interface should be hooked to USB. The interface between USB and RS485 can be soldered with one...

LTC3896 is a high voltage inverting switching regulator controller that drives an all N-channel synchronous power MOSFET stage. Most low to medium power inverting DC/DC converters use a coupled inductor or transformer: this device uses only a single inductor. The chip converts a 4V...

Jason Jones has tipped us with his latest project. He is working on a semiconductor curve tracer and details his progress on his website. I have thought about this a lot recently and - in order to get the cost down - the unit must have a cheap or available power supply and must coopt...
