The prize this week is a breadboard power supply. This contest will run for one week (December 30 2012 – January 4, 2013). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Please do not give the answer in the comments. Send [...]
This Tweeting Cat Door Project uses the new Electric Imp controller. If you haven’t heard about the Electric Imp before watch the video that Engadget recorded at Maker Fair at their booth. The Electric Imp is a neat idea, the form factor is an SD card but that was just chosen since there are lots [...]
If you’ve ever wanted to shoot someone with a Nerf gun, but just didn’t have the energy to get off the couch, this hack may be for you. It’s also a good way to ward off zombies if another apocalypse, Mayan or otherwise, is on the horizon. Although the effects are very cool, as seen [...]
Check out this Portable CNC in a Box (translated into English). If you ever wanted to setup a CNC machine in a mall on the weekend at a small booth this would be the ideal machine for that. Just think of all the custom trinkets you could make with it. Best of all [...]
In this tutorial, Luca shows how to add WiFi connectivity to your Arduino boards without using a WiFi shield. Instead, he has combined a standard Ethernet shield with a commercial (and quite cheap) WiFi router: I found the TL-WR702N nano router by TP-LINK that, with a cost of about 20€ on eBay, can work also as a wireless client: [...]
If you have a laser machine collecting dust because you have nothing inspirational to cut you are in luck. This Laser Cut Hand Crank Marble Machine by Martin Raynsford is the final version after a ton of experimentation. It looks like it is lots of fun and would be simple to stick a motor [...]
If you haven’t listened to the latest Amp Hour (episode #126) you may not have heard about this $269 High Speed Automatic Pick and Place Machine. I have very little information on it since I can’t read Chinese, the videos demo the system quite well though. For such a small machine it sure looks [...]
I have been wanting to play with my RedBearLab BLE Shield for some time, but have been too busy. This weekend, I finally was able to allocate some time to experiment with it. I decided to do something relatively easy as my first project, so as to familiarize myself with the Bluetooth API’s on both [...]
In his blog, Michael describes a nice 4WD robot he realized by means of an arduino-compatible board, a motor shield and a couple of XBee radios, which have been used to implement a simple and effective remote control. Actually, the remote is made up of a standard breadboard equipped with a joystick, a couple of buttons (that can turn [...]
Happy holidays! The prize this week is an ultrasonic sensor, a breadboard and a breadboard power supply. This contest will run for one week (December 22 – 28, 2012). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Hint, this board [...]
If you want to play with line voltage you need to be a lot more careful compared to working with 5 or 12 volts. Viktor has built a nice compact system for easily interfacing line voltage powered items to his DIY projects. Instead of trying to breadboard the line voltages or make a temporary [...]
[Paul Mandel] just finished building this knock box project. It’s a familiar concept that uses a solenoid to tap on the side of the box. The Arduino driven setup monitors vibrations on the lid. When you knock on the box, it records the pattern and plays it back using the solenoid. He was inspired by [...]
Here’s a project that let [Rick Pannen] try his hand with an OLED display and a rechargeable power source. He calls it OLEDuino which is a mashup of the display type and the Arduino compatible chip running the whole thing. He figures it will serve nicely as a geeky name badge but also ported a Breakout type [...]
[Ladyada] and [pt] had an old keyboard from NeXT, but since it used a custom protocol it wasn’t usable with modern hardware. So they built a custom device to convert the NeXT protocol to USB. The device uses a Arduino Micro to read data from the keyboard and communicate as a HID device over USB. It [...]
Workshop 88 is offering our introduction to the Arduino platform at our makerspace in Glen Ellyn. Class attendees will learn how to configure their arduino programming environment, how to design simple circuits for interfacing with the arduino and how to … Continue reading →
