Arduino Lightning Detector

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...

AutoResetRRR – 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....

USB to RS485 converter

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...

1.8″ DIY Photo Frame using and Arduino Nano and a ST7735 Color TFT display

In this video educ8s.tv is  going to show us how to use the SD card slot of the popular 1.8" Color TFT display which uses the ST7735 driver. Then we will save some bitmap images in the SD card and we will display them on the display. In other words, we will build a simple Photo Frame...

150V DC/DC inverting controller: single inductor, ground-referenced control

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...
