What do you do if you’re given a gigantic ancient printer? If you’re [IronJungle], you throw that printer on your workbench and salvage all the parts you can. After coming across a few stepper motors in an old Oki printer, [IronJungle] decided to automate an Etch-a-Sketch with the help of a PIC microcontroller and H-bridge chip [...]
[Richard] and [Jay] needed a WiFi connected data logger for remotely monitored aquariums. After working diligently for three years, they’re finally finished. While the Knut was originally designed to keep tabs on a few huge aquariums, it’s more than capable to log all sorts of data and send those sensor readings to your email address. Knut [...]
[Blair] sent in a project he’s been working on for a while. It’s called the Crayolascope, and it allows for the creation of an extremely low-fi volumetric display using a Crayola Glow book. The Crayola Glow Book is a pretty neat toy composed of four clear plastic panels. Each of these four panels are illuminated from the [...]
[Alexandre] wanted to set up a web-based temperature logger with his Arduino, but found the Arduino Ethernet shield a little finicky. Since his Raspberry pi was just delivered, he figured he could use the Raspi as an Ethernet shield with just a little bit of coding. After [Alexandre] set up his Arduino to send a thermocouple through the [...]
There were quite a few 3D printers at the NC Maker Faire this year (like the [Fablicator], several [RepRap]s, and [MakerBot]s) as well as a few subtractive machining devices including a wood lathe, a [ShopBot] display (one of the sponsors), and my little CNC router. There was even a little [Eggbot] on display, which combines [...]
This 3d printed case houses the already small [TP-Link TL-WR703N] but also makes room for a custom expansion board. The expansion board is designed to make the device more hacker friendly, and who doesn’t need a nice case to hold it? Since the router board already has a USB port (intended for use with USB 3G [...]
The Bullduino’s are starting to arrive. When [Arclight] received his in the mail the first thing he did was to share the hardware details. Of course this is the hardware that participants in the Red Bull Creation contest will be receiving ahead of this year’s contest. The board is an ATmega328 Arduino clone. Instead of [...]
[Teknynja] was looking for a way to control several discrete AC-powered devices using a microcontroller, and while he did consider the Powerswitch tail 2 from Adafruit, handling 5 devices would get pretty expensive. Rather than buying a complete off the shelf solution, he decided to build his own 5-way switched outlet. He picked up a [...]
Looking for something to do this fine Saturday morning? For the US and Canadian readers out there, the fourth weekend in June is amateur radio field day, a day when all the amateur radio and ham geeks get together, string up a few antennas, and do their yearly community outreach/contact as many other radio heads [...]
If you have an iPad you know that there will come a time when you need to have it stand on it’s own. Watching a video, reading a recipe, following some online steps for your next project are all times when you will want a stand. The next issue is that you will want a [...]
