[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 [...]
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 [...]
We’re back from our holidays. We have learned that Metaxa makes us ill, and that there are a million and one useful things you can do with an aubergine. I’ve got a bit of video to keep you entertained while I burn through the enormous backlog of email that built up while I was away. [...]
[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 [...]
[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 [...]
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 [...]
[Sebastian] wrote in to update us about the optical sensor project he started a couple of years ago. You’ll find his most recent update here, but there are four different post links after the break that document various parts of his progress. You may not recall the original project, but he was looking to add [...]
Many solutions exist for publishing data coming from Arduino boards on the web. Bangon Kali, in his detailed tutorial, proposes his novel approach, which makes use of several widespread and open-source technologies, such as Node.JS, jQuery and Apache: Using the USB, the Arduino Board is connected to the PC serially to a certain COM port which the [...]
[cHaRlEsg] posted a rant, then posted full instruction on how to build this electric go-kart for yourself. Now the rant calls this an unobtainium-free sibling to the Chibikart. We’re sad to report that the unobtainium he’s talking about are the hyper-awesome hand-wound hub motors that powered the original kart which left us dumbstruck after seeing [...]
Look at it. Just look at it! This board is a lie. It doesn’t exist (at least not what’s seen in the image here). Instead this is a lifelike rendering made from Eagle CAD files. We’ve already seen that it is rather easy to pull Eagle CAD files into Google SketchUp thanks to the EagleUp [...]
