LED Candle Light Flicker with Arduino
I’ve build a simple candle light with an LED which is powered by an arduino. I have one of these cheap candle lights, but they aren’t very smooth and they don’t look like a flame, so build one myself.
Alienware Concept UFO is a Switch killer that plays PC games
The quest to play demanding AAA games on the go sans gaming laptop has long been a dream of PC makers. And the Alienware Concept UFO realizes that dream in spectacular fashion.
There have been a few promising attempts in the past, but nothing feasible or compelling enough to take off with mainstream gamers. Alienware has created a device so tantalizing, the company has done something it’s never done before –– show off a concept product to the public.
Alienware’s latest venture takes familiar concepts (like the Nintendo Switch) and builds on them to forge what could very will be the future of mobile PC gaming.

Build your own tracking and GoTo mount for DSLR astrophotography
Astrophotography can be challenging, in a large part because your subject matter — or your base, the Earth rather — is constantly moving. In order to take excellent long exposures of far-off objects, Redditor intercipere came up with a beautiful 3D-printable, star-following mount that holds and rotates a DSLR camera.
Now intercipere can simply input the RA/DEC coordinates and the device will automatically move to a desired target in the sky.

Apollo DSKY Computer Simulated with Arduino Uno and Touchscreen
To celebrate the 50th anniversary of the Apollo 11’s landing, hacker Mark Wilson decided to create his own DSKY computer replica using an Arduino Uno and 240×320 LCD display. While Wilson is quick to note that it’s not a faithful representation of the Apollo Display and Keyboard module, or DKSY, it at least gives users a feel for the machine and even acts as a clock when you’re not pretending to travel through space.
A Surprisingly Affordable 2000 Watt Induction Heater for Your Workshop
An induction heater is a multiuse tool that can be used to heat metallic objects quickly and locally. It relies on induction, in which a coil can induce eddy currents within conductive material that is placed inside of the coil. This requires a very quickly-oscillating alternating current in order to induce the eddy currents that heat the metal. Induction heaters have many practical industrial applications, and they can also come in handy for hobbyists who don’t want to work with open flames or other heat sources. If you have a need for one, you can follow DIY KING 00’s tutorial to build your own affordable 2000 watt induction heater.
“Muscle Wire” – Whats that?
MigaOne is a unique electric actuator based on Shape Memory Alloy (SMA) wire, also known as muscle wire.
