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
A power supply is the heart of any good electronics lab. Hansaka Perera built his instead of purchasing one. It sure has a ton of bells and whistles. I don’t think I have seen a supply that shows what it is pulling from the wall, the LCD display in the center of his shows the total draw from the wall plug. The case of the supply is very nice and
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.
SomethingUnreal has built a simple system to demonstrate how a PID Motor Speed Controller works. The system is spinning a piece of cardboard on a toy DC motor. The motor is powered by an H Bridge. An optical sensor provides feedback to the system so that it can see the actual speed and adjust the H Bridge accordingly. The software running on the PC is very nice as it allows
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
For everyone that has a fond memory of the C64 this tiny emulator might be of interest. The kickstarter failed but everything is listed so you can make your own. Via: Make “Hardware components MCU: STM32F756IGK6 (ARM Cortex-M7, 216Mhz, UFBGA176) HDMI transmitter: ADV7511W (165Mhz, LQFP-64) SDRAM: IS42S16400J-5BL (200Mhz, 64 Mbit, FBGA) Mathias created the MEMWA2 using a custom-designed 6-layer PCB just big enough (65 X 45 X 20mm) to fit
