Long Range nRF24L01 Testing

at 9:46 pm. Filed under Cool Gadgets, Electronic Hacks

 
 

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 packet throughput based on distance.

Intelligent Headlight Technology

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 headlights continue to illuminate as much output as possible without dazzling other drivers on the road.

Raspberry Pi Vehicle Accident Alert System

at 9:56 pm. Filed under Cool Gadgets, DIY Hacks

 

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

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 have a microcontroller that reads in data from a SD card and displays the content line by line after being initiated by the push of a button.

Thanks for the tip Jim.

DIY EMP Generator

at 10:39 pm. Filed under Cool Gadgets, DIY Hacks

 

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 caution since permanent electronic damage can occur with this type of device.

CVT Transmission Basics

at 5:49 pm. Filed under Cool Gadgets

 

Engineering Explained goes into some details about how CVT Transmissions work. Love them or hate them it is an interesting piece of tech.

 

“A continuously variable transmission (CVT) (also known as a single-speed transmission, stepless transmission, pulley transmission, or, in case of motorcycles, a twist-and-go) is an automatic transmission that can change seamlessly through a continuous range of effective gear ratios. This contrasts with other mechanical transmissions that offer a fixed number of gear ratios. The flexibility of a CVT allows the input shaft to maintain a constant angular velocity.”
