Hooking up a laser to a CNC gantry isn’t exactly an Earth-shattering innovation, but it does make for a useful tool. Even a cheap diode laser mounted to an old 3D printer can do engraving, m... Read more
Rakwireless has just announced a new module part of their LPWAN family: RAK4260 LoRaWAN module based on Microchip ATSAMR34J18B LoRa SiP and at just 15x15x1.2 mm, one of the smallest LoRaWAN... Read more
Using tiny arrays of carbon nanotubes, a team of researchers at Rice University has designed nanoscale incandescent light source that could be tuned to precisely emit at specific wavelength,... Read more
Swedish and Chinese scientists have developed organic solar cells optimised to convert ambient indoor light to electricity. The power they produce is low, but is probably enough to feed the... Read more
Here’s a six word tragedy: My arduino needs four AA batteries. Really? Isn’t this 2012? Where’s my jetpack?!! Here’s a way to the future — a way to make a sol... Read more
We all know the story arc that so many projects take: Build. Fail. Improve. Fail. Repair. Improve. Fail. Rebuild. Success… Tweak! [Kris Harbour] is no stranger to the process, as his impress... Read more
The global population increased at its fastest rate in recorded history during the twentieth century, rising from around 1.6 billion in 1900 to over 6 billion in 2000. And due to the rising... Read more
In days of yore when solar panels weren’t dirt cheap, many people (and even large energy companies) used solar trackers to ensure their panels were always physically pointed at the sun to ma... Read more
One of the main advantages of cheap wireless modules is that they get used in consumer electronics, so if you know what’s being used you can build your own compatible hardware. While investi... Read more
In this project I will show you how to create a solar tracker which like the name implies can follow the movement of the sun throughout the day. And at the end I will show you the energy har... Read more
