3D printing no longer seems to have the wow factor that it did a few years ago, I remember how crazy it seemed a year and a half ago when when Bradley Rigdon demonstrated how to print a 3D bearing. Most of us have now seen something that has been printed in a 3D printer. This is thanks in large part to the MakerBot which has brought inexpensive 3D printing
Greg from Electronicsnerd will be building some RF projects over the next few days. Today he presents an AM Broadcast Band Rejection Filter for Shortwave Reception which is based on the work of Joseph J. Carr. You can find the circuit in this article (PDF). With only 7 components it’s a simple circuit that could be built in a short time. “With an eye toward proper RF construction techniques, I
An elevator is something that many people rely on to get around. What happens when a out of the box thinker is stuck on the 5th floor of a building and in need of an elevator to get in and out of his suite? Step 1 is to ask for an elevator to be installed, step 2 is to take it into your own hands and make your own elevator!
This project goes to show that with a bit of imagination you can create some very cool things with off the shelf components. The guys from ADNANONLINE have done. By moving your body around you can control the toy RC car. The Kinect is watching the movement, information is then sent to an Arduino so that the real world control of the RC car is possible. “RC Car controlled by
If you are dealing with LiPo batteries it is wise to use some commercial built charger since they have some special charging needs which is harder to pull off with a dead simple circuit like we could do with NiCad cells for example. Dane had one of these special charging units but has now hacked it to allow him to stream out the serial data from the unit so he
The prize this week is a mini tripod to help you get some great pictures of your next project. This contest will run for one week (July 23 – 29, 2011). Ending time is based on central standard time. To enter, identify the item pictured above. Please do not give the answer in the comments. Send an email to contest @ hackedgadgets.com with “Name the Thing Contest” as the subject,
Next time you are working on a laser project that needs a small DC motor or a robot arm that is in need of a few gears make sure you have a copy of Unscrewed by Ed Sobey handy. Most of us makers and hackers have a large pile of used parts (some call them junk boxes), they come in all shapes and forms, old VCRs that got retired, the
