I don’t know if you follow the Engineer in Wonderland series on Electro-ramblings, but when Alice gets into the workshop the content is worth sharing – consider Alice an uber-Gadget Master!
Here’s a very interesting project, with a very worthy motive behind it, reports Technabob. Some engineers at Libelium, a wireless sensor network company, decided to help the people of Japan, around Fukushima, determine levels of radiation for themselves.
Poorly-made green laser pointers can damage you eyesight, and mighty US tech lab NIST has devised a home table top experiment to help separate the dangerous from good.
A reader writes that he had a need to generate a single cycle of a very low frequency near sign wave, which was to be used to test software that measured the parameters of a waveform generated by a sensor.
Video: Testing is a crucial part of the development cycle, as any gadget master will have suffered, and here’s a cool app to help the process, when you find yourself turning to use a PicoScope.
This great looking gear clock tells the time in a unique way. A PIC 16F628A microcontroller with an external 20MHz crystal oscillator times a stepper gear, which drives a minute display, which also drives an hour display…
Here’s a great project, recommended to Gadget Master by our own indomitable device-builder, EW’s Technology Editor Steve Bush. It’s the Hotbox temperature logger.
Now he’s got the power to cut lightning down to size People have always been fascinated by the fury of the heavens. Electronics prodigy Richard Hodgkinson created a lightning distance timer so he would no longer have to manually calculate the approach or retreat of a thunderstorm. He recycled…
