Fresh hacks every day
Most bits of a computer we take for granted today – the mouse, hypertext, video conferencing, and word processing – were all invented by one team of researchers at Stanford in the late 60s. When the brains behind the operation, [Douglas Engelbart], showed this to 1000 computer researchers, the demo became known as The Mother of all Demos. Luckily, you … Read the rest
Here’s an LED indicator which was made at home out of a Silicon Carbide (SiC) crystal. The concept is simple, but a bit of trial and error goes into getting that tiny amber spot to light up.
The guesswork comes in finding the right piece of crystal. First [KOS] broke it into tiny pieces, then he started poking the … Read the rest
[Nav] got the bug for a tiny little laser cutter. He pulled off the build, and has just finished the second rendition which makes some nice improvements. He’s was hoping for a laser cutter, but we think this really shines when it comes to branding objects like the scrap wood seen above.
This joins a long line of optical drive … Read the rest
Even though NVidia and ATI have been open-source friendly for a while now, there still isn’t a true open-source graphics card. [Anton] and [Per] are trying to fix that by building his own graphics card around an FPGA. The project is called ORSoC, and it’s available on opencores.com.
The guys are building the ORSoC graphics card around a Digilent … Read the rest
[Instrument Tek] isn’t messing around with a hobby-sized greenhouse. In fact if it were any bigger we’d call it a commercial operation. But what interests us is the professional-quality greenhouse automation he built around and Arduino board.
The greenhouse is about what you’d expect to see at a nursery, except the footprint is somewhere around 10′x10′. It’s a stick-built … Read the rest
[Jake] took some cheap hardware and figured out a way to use it as a huge home automation network. He’s chose a Raspberry Pi board to connect the radio controlled power outlets to his network. He wrote about his project in two parts, the first is hacking the RC outlet controller and the second is using the Raspberry Pi to … Read the rest
If you’re building a 3D printer, the most complicated part is the extruder. This part uses a series of gears to pull plastic filament off of a spool, heats it up, and squirts it out in a manner precise enough to build objects one layer at a time. [Chris] made his own extruder out of a hot glue gun and … Read the rest
