 If you have ever wanted an X-Ray machine in the lab to assist in tracing out the PCB traces that run under components? John McMaster built just that. He used a dental X-Ray machine which has a very small image size. A controller moves the system to allow for multiple images to be taken and stitched together later. The result is demystified reverse engineering. Via: Make
Alex Whiteway, Sungjoon Park and Rameez Qurashi built a great FPGA-Based Rubik’s Cube Solver. The system uses 3 robotic grippers to manipulate the cube, a camera to “see” what state the cube is in at the beginning and an Altera Nios II FPGA computes how to solve the cube. There are lots of algorithms available, the team looks at many of them and decided to roll their own solution. It isn’t
This The Switch Lab electric vehicle kit is designed for students to build it in a classroom. It comes with everything you need to build a sporty electric vehicle in about one week. The kit starts at around $20K and is designed to be built by one class and then stripped back down for the next class to build. The basic model comes with lead acid batteries, the higher models
Proto G sent in his latest project. It is a DIY WiFi Smoke Detector that he built to monitor his battery storage area. The system uses IFTTT (If this then that) to send out the messages. A full walk through of the device will be coming soon.
I remember making a hand launched flyer using a straw and 2 circular hoops of paper. This Circle Plane when scaled up is very impressive. It doesn’t look all that controllable but the other planes had a blast flying through the large moving target. It was nice that the body and hoop were made out of cheap materials so a bit of destruction was not a big deal.
A well timed strobe light can do some amazing things. Artist Elliot Schultz placed these embroidered patterns on a record player (which naturally spins at a known stable speed). The resulting images are fun to look at. Via: Make and Laughing Squid “This project encourages viewers to watch and engage with animation physically. Discs were created with animated sequences embroidered onto their surface. They have been designed to be played
Water, Lye and Silica Gel are used to make a product called water glass (also called Sodium Silicate). Mixing the Lye with the water and then adding the crushed desiccant packets will create a mixture that can be used as a high temperature adhesive. “Sodium silicate is the common name for compounds with the formula Na2(SiO2)nO. A well-known member of this series is sodium metasilicate, Na2SiO3. Also known as
