turning 3D printed plastic parts into metal objects is not a new concept. but we don’t see a lot of it and took pleasure in enjoying the documentary version of [3DTOPO’s] lost PLA metal casting process so much we figured you’d want to see it too. The thirty-five minute video walks through every part of the process […]
If you’re major about astronomy these days, you want to have a computer controlled telescope. Although you can easily purchase a pre-made cable television that connects the two devices, where’s the fun in that? [Charles], being an avid Maker, has created a good step by step guide so you can build your own. This is […]
There are a lot of hacks out there for Ikea’s Dioder LED light set. [Lambertus] wanted to create an easy and economical ambilight while keeping the hardware modifications to a minimum. He also wanted anybody to be able to easily duplicate his work. He recently wrote in to share his successful solution. The customizations boil […]
The lowly Arduino, an 8-bit AVR microcontroller with a pitiful amount of RAM, awfully little Flash storage space, as well as efficiently no peripherals to speak of, has much better speech recognition abilities than your Android or iDevice. Eighty percent accuracy, compared to Siri’s sixty.Here’s the video to show it. This uSpeech library produced by […]
In situation you haven’t heard, the Sikorsky Prize, an aeronautical difficulty to develop a human-powered helicopter that can hover at three meters for a full sixty seconds, has been claimed. This extremely tough engineering accomplishment was accomplished by AeroVelo, together with a great deal of assist from the university of Toronto as well as a hold […]
The development of the Arduino brought the world of microcontrollers to hobbyists, students, as well as artist the world over. ideal now we’re in the midst of a new growth in hobbyist electronics with the Raspberry Pi, however we can’t expect everybody to stay in the comfortable, complex, as well as power-hungry world of Linux […]
They’re not a 2600, but the Atari 400, 800 and 1200 are amazing computers in their own right. With only basic built in to the ROM, they’re not especially useful or fun, as [Jeroen] found out when he acquired an 800 with a broken tape drive. There are options that allow you to load emulator […]
With procedural content generation, you build data algorithmically rather than manually — think Minecraft worlds, replete with all the terrains and mobs you’d expect, but distributed differently for every seed. A lot of games use algorithms similarly to generate appropriate treasure and monsters based on the level of the character. Game developer [Oleg Dolya] built a random city […]
These arcade buttons started out as illuminated buttons. but they were bulb-based which only allowed for one color. [Jon] and his pals at the Leeds Hackspace wanted to find a way to retro fit them with RGB LEDs, without changing the buttons themselves. The hack lets them replace the bulb with an addressable circuit board. The […]
[Fileark] had the backlight on his digital photo frame go out one day. These are normally chilly Cathode Fluorescent Lamps which need an inverter to source the voltage needed for appropriate operation. When they stop working, the inverter is normally to blame. considering that that circuit is made up of quite little surface install circuitry, he made […]
