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 🙂 Everytime I solder a SMD LED on a pcb I have to turn on one of my multimeters and flip it over to diode-test mode and then probe the

An adventure of the Southern Appalachian Space Agency, by Travis Goodspeed <travis at radiantmachines.com>, as presented at Summercon 2013, inspired by the lectures of Adam Laurie and Jim Geovedi, with kind assistance from Skytee. At Black Hat DC in 2008, I watched Adam Laurie present a tool for mapping Ku-band satellite downlinks, which he has

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

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

Bootloading 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. This

An Arduino is an open-source microcontroller development board. In plain English, you can use the Arduino to read sensors and control things like motors and lights. This allows you to upload programs to this board which can then interact with things in the real world. With this, you can make devices which respond and react
When I was a kid my father had a panic button under his desk that was wired to call 911. While I thought this was pretty cool at the time, it later occurred to me that he had this because the neighborhood that his business was located in was a bit rough, and — perhaps
