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
Marcelino Fort Garcia from Tbi Robotics in Barcelona is producing a high speed low cost pick and place robot. He has made lots of videos demonstrating how he has got to this point. The full code is also available free for everyone to play around with also. He will be updating the blog with new sections as he continues to develop the system. I am looking forward to seeing
Before you watch the video below have a close look at the picture above and guess how this was done. There are 3 slots cut into a piece of wood, there is a real solid nail placed in the wood. Each section of wood including the outer sections are solid (just as it looks). You would not be able to remove the nail by sliding it. This was a
