Mechanical Solar Tracking Mechanism
Details from Mechanical Solar Tracking Mechanism
Introduction: In photovoltaic systems, solar tracking mechanisms help minimize the angle of incidence (the angle that a ray of light makes with a line perpendicular to the surface of reception) between the incoming light rays and solar panel, which...

Heroineclock II
Details from Heroineclock II
It was a long & hard process between 1 month of commutes, but Heroineclock I was finally shut down after 13 years of blinking & replaced by a much better Heroineclock II, factoring in much more experience. All the Chinese options which appeared...

Add a Bed Level Sensor to a 3D Printer Very Simply
Details from Add a Bed Level Sensor to a 3D Printer Very Simply
I used a cheap relay board that I happened to have on hand. These are well under $2 from the usual sources (example: https://www.gearbest.com/relays/pp_226384.html?currency=USD). Yes relays are low tech but there were a couple of things in favor...

Precision current generator
Details from Precision current generator
That's "Yet Another Fork" from #YGREC-ECL:-) (see moving forward) I share this design because it's very handy, cheap, useful and the parameters are easy to adapt for other uses and ranges. It might look messy but it's just due to poor planning...

Li-Ion Battery Emulator
Details from Li-Ion Battery Emulator
Basics The core of the electronics is a simple op-amp voltage follower: But I need to supply up to 1A, which (most) op-amps can't do. So, the next step is to buffer the voltage with two bipolar transistors. This is a classic "push-pull" class-B amplifier...
