Sat, 22 Oct 2016 03:46:48 +0000Long 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 […]
Sun, 16 Oct 2016 02:35:59 +00001000 watts of light doesn’t sound like much. But 1000 watts of LED light mounted to the bottom of a drone flying overhead looks amazing. The video captured at the end of the video is stunning and the smoke scenes are mesmerizing.
Fri, 14 Oct 2016 18:29:48 +0000Robotic automation is great. Set and forget, once dialed in this system will create parts that are identical and not complain about coffee breaks. Love the creative jigs that enable the robot to handle materials that might not be placed with high precision.
Fri, 14 Oct 2016 04:05:00 +0000Techmoan got his hands on a few SX-64 Computers. This is the portable version of the C-64 that everyone loves. He needed to do a bit of repair but in the end he got 2 working machines. They are still going for a good price since these units are still rare compared to the regular C-64 […]
Mon, 10 Oct 2016 20:07:31 +0000Headlights 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 […]
Mon, 10 Oct 2016 00:28:04 +0000A 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 […]
Sat, 08 Oct 2016 03:56:58 +0000SVS 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 […]
Tue, 04 Oct 2016 04:24:54 +0000SomethingUnreal 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 […]
Sat, 01 Oct 2016 04:13:59 +0000RGB 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. […]
Fri, 30 Sep 2016 04:39:48 +0000FPS 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 […]
