If you are looking for a display on the go this new Kickstarter will be of interest to you. It is an interesting collapsible display that uses a short through high power DLP projector to get the job done. It has already tipped so this will become reality. Until a paper think color roll up display is available this will be the next best thing. “SPUD is the only
If you are looking for a project build that can probably be put together with some items out of your junk box and about $10 in parts. The main drive for the system are the motor units from 2 old DVD drives. An Arduino controls the system. “components used 1. 2x old PC DVD Writer 2. Arduino nano 3. Small servo motor 4. L293D 5. Zero PCB”
Long range data transmission can be useful. There are lots of options out there but the cheap nRF24L01 modules with an external antenna can work wonders. iforce2d has done lots of testing with a nice DIY rig. He has a stationary transmitter and a receiver mounted on his car, the car rig has a GPS and SD card modules to that he has the ability to record the
Headlights today are much smarter than they were not that long ago. Using cameras the headlight system can detect oncoming vehicles and vehicles in front of you. The headlights can then block out the area that the beams shine, this means the end of constantly switching between high and low beams when you are close to other vehicles on the highway. It is also much safer since the
SVS Embedded has built a nice proof of concept. It has a ton of peripherals hanging off the Raspberry PI. The system uses a vibration sensor and accelerometer to determine if an car accident has occurred. An LCD display reads out the information for the user. GPS captures the location of the incident and transmits it to a cell phone using a SMS transmission using the cellular radio.
RGB Light Stick Painting doesn’t look very impressive when you watch it in action but with a long exposure and some well timed flashing lights the end result is amazing. The slow fading colors and a simple twirl of the stick looks very nice. The stick has 200 LEDs and is 2 meters tall. Not sure what is powering the unit but I suspect the LEDs are serial and
FPS Weapons has built this DIY EMP Generator. It uses some off the shelf components to generate some large EMP pulses with the push of a button. The device runs off a rechargeable lithium ion battery, a high voltage converter goes through a spark gap and then through a coil. The coil was made using some varnished wire. Hot glue was used liberally to keep everything in place. Use this device with
