While LED based solid-state lighting continues to gain ground, and several major challenges have been solved, some still remain. Energy savings and the savings that a long product lifetime brings certainly have spurred adoption in a long list of applications. Cities, sports facilities, retail, medical, residential and industrial use, are all on the rise. The …
From time to time many of us are facing the same problem when trying to charge your smartphone or tablet from the USB port – it just not charging. Recently I have bought USB car charger to power my Samsung Galaxy Tab 10.1 on the road just to discover it doesn’t work. Even though the …
This weeks PAW is something that I have wanted to have for a long time but never gotten around making – until now that is 🙂 Every time I solder a SMD LED on a pcb I have to turn on one of my multi meters and flip it over to diode-test mode and then …
An adventure of the Southern Appalachian Space Agency, by Travis Good speed <travis at radiantmachines.com>, as presented at Summercon 2013, inspired by the lectures of Adam Laurie and Jim Geovedi, with kind assistance from Sky tee. At Black Hat DC in 2008, I watched Adam Laurie present a tool for mapping Ku-band satellite downlinks, which …

This is a great process achievement by SiTime. They have managed to cure the problem of MEMS oscillators over temperature at the source—the MEMS itself. Kudos to the process engineers! SiTime Corporation has introduced the TempFlat MEMS. Until recently, all MEMS oscillators used compensation circuitry to stabilize the output frequency over temperature. This new design …

This USB to serial (TTL) converter project is easy to build, it is simple and inexpensive. It is based on the PL2303SA USB to USART bridge from Prolific. The PL2303SA chip is not required an external crystal as the internal clock oscillator is continuously tuning up to USB bus frequency. Having chip in SO-8 packaging …

I and my friends like to have fun in summer. We like to fool around with music when we are camping. To make those parties more likely to professional ones I have made portable 9V LED strobe. For my surprise it really gives a big effect. I hope you will like it! Here is the …
Over the course of the last 5 months I developped an application to visualize Gerber data. The goal was primarily to review Gerber files before sending them to a PCB fabrication house. It is very similar to the Mayhew Labs online Gerber viewer, except it’s offline (and has a few different features). My tool is …
Boot loading an Arduino with a ZIF socket allows you to easily program a lot of chips at once without worrying about mangling the pins. The reason for this is that ZIF stands for “zero insertion force,” and as the name implies, ZIF sockets don’t require any force to take the chip in or out. …
