AutoResetRRR – Automatically reset routers/cameras/servers

Intro 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. If all is well, they can shut down safely and start back up. If not, the power cycle can fix a thing or two.

USB to RS485 converter

g 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 of the many FTDI interfaces with added RS485 driver, or bought as assembled module. There is always the third option. I made it

DIY Mini Quadcopter with 3D-Printed Frame and Custom Firmware

I wanted to try my hand at a true “DIY” project, designing and building my own micro quadcotper frame and writing my own firmware in C++. In this post I will describe the frame and build; in my next post I will talk about the firmware. Excluding stuff I had lying around the shop, (heat-shrink

RC snubber calculator spreadsheet

RC Snubber Calculator Spreadsheet In power switching applications, a designer often has to contend with spurious oscillations. These are the result of parasitic capacitance and inductance on the board and behave like the step response of an RLC circuit. These transients can induced undesired noise in neighboring circuits and create over voltage spikes that can
