Soldering irons are the primary tool used for soldering, and we use ours all the time for soldering. But for leadless parts, like QFNs, or ultra-tiny components that need rework, hot air can be superior!
Powered by the PIC24F08KA101 microcontroller with over 160 LEDs that are controlled in 9 groups of 18 each. Each group of LEDs are forming a circle and each RGB component is controlled by PWM, with effective resolution of about 13 bits. It’s amazing to watch the color transitions. Read more to watch more!
This is one of the many color sequences this unit can produce.
This honours project involved the construction of a human operated diwheel. Many diwheels in the past have been human powered or powered by IC engines. This one is purely electric. It has additional functionality lacking in other models, including inbuilt dynamic lateral stability and slosh control to prevent “gerbiling” or tumbling in aggressive braking or acceleration maneuvers.
The Park Ranger is an ultrasonic-ranging prototype designed to assist drivers who are backing into tight areas. The ranger uses ultrasonic pings to measure distance to the object behind and indicates this distance by sending audible tones to your FM radio. Optional panel-mount LEDs offer visual aid for calibration as well as warning drivers behind you.
Endeavour successfully launched today from the Kennedy Space Center at approximately 8:56 am eastern for its 25th and final mission. Mission STS-134 headed by Commander Mark Kelly, Pilot Gregory H. Johnson and Mission Specialists Michael Fincke, Greg Chamitoff, Andrew Feustel and European Space Agency astronaut Roberto Vittori, will last 16 days.
Bob Davis is back! With his upgraded DIY Earthquake Predictor using the Arduino and some hall effect sensors, Bob hopes to get better results predicting Earthquakes. Here’s a clip of Bob explaining how it works:
