Sean Michael Ragan shows us how he built the Bike Phone Charger project that Alastair Bland wrote for Make magazine. It uses an interesting component construction inside a plastic housing. I think a great addition to this project would be cram a small USB battery system in the housing so that the system charges a battery so that it could be used when the bike is stationary. “The charger circuit
Chris Rybitski just shared his latest project with us, it’s a Stage Platform Robot. It is a way to remotely move stage items around. He built a 9 inch tall robot that can drive around with 900 pounds on its back. He built the majority of the metal frame from square tubing that has been welded together. There is an Arduino controlling the robotics and a speed controller that
The prize this week is an Arduino Mini Clone. This contest will run for one week (July 14 – 19, 2013). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Please note the image above is a side view of the thing. Please do not give the answer in the comments. Send an email to contest @
Thanks to Samer Muhi for sending in a video of his latest Quadrotors Wireless Power Transfer project. He is able to power his quadcopter with up to 20watts of energy using resonant inductive coupling. You can see the main coil sitting on the table which is operating at a resonant frequency is 800kHz. On the quadcopter arms you will see the second coil and some circuitry in the board
This Arduino Quadcopter by Kyle Fieldus has iPhone Control, similar to the AR Drone you can tilt the phone to control the quadcopter. Touch OSC is being used to design the phone interface, there is also an Android version available. The system chain is a bit complex since the phone is sending the input data to the computer, the computer determines what should be done on the quadcopter and
When developing a project there will come a time that you will need to communicate with the outside world. Serial communication is often the simplest way to get data in and out but when it comes to wireless, Bluetooth is quickly becoming the way to go. Bluetooth modules are getting quite inexpensive and every smart phone has it built in these days. Techbitar has written a great Instructable that
Dave from the EEVBlog does a Nintendo 64 Game Console Teardown. Looks like Nintendo figures the regular security screws such as torx was not worthy of their housing. They have used some crazy security screw that I have never seen before. It didn’t hold up to a drill with a large drill bit though! I am surprised to see how much metal there is on the inside. Next time
