USB curve tracer for NPN transistors

Dilshan Jayakody documented his USB port base NPN transistor curve tracer project: Curve tracer is an electronic test instrument to analyze the characteristics of transistors and other discrete semiconductors. In this post we construct USB base curve tracer to analyze properties of NPN transistors. This curve tracer is build around Microchip’s PIC18F4550 MCU and it use […]

Automatic monitor brightness controller

Dilshan Jayakody writes: This is an automatic “monitor brightness controller” based on environmental light conditions. This system use USB port base sensor unit to measure the light level and control monitor brightness accordingly. We design this system to reduce the eye stress by matching the monitor brightness with environmental lighting. Project info at Dilshan Jayakody’s blog.

Programmable CW Morse Keyer / beacon

Marko Pavlin has designed a Mini USB dongle with STM32F0xx , he writes: Mini USB dongle with STM32F0xx is suitable many for simple, mini projects. I attached speaker to Timer14 PWM output (Pin PA6) and LED (or optocoupler connected to PTT) to GPIO pin PA0 The provided software is based on USB Virtual Com Port (VCP) device. […]

Nifty USB LED light

Isonno writes, “One of the hit discoveries of Hacker Camp 5 were these little USB lights. Plugs in either way, and you turn on/off/dim by touching the back. Turns out the show is run by a chip called the Sigma SGL8022W. The datasheet has the schematic.” Via the forum.

FlashProg – USB serial flash memory programmer

Dilshan Jayakody  published a new build, the FlashProg project – a USB serial flash memory programmer: FlashProg is USB base flash memory programmer to work with 3.3V serial flash memory devices. This programmer is specifically design to read, program and configure 25x series, serial flash memory devices which are commonly used to store BIOS in PC […]

ChipHeadBang – design for an USB to Serial converter with ICSP header for (slow) bitbang programming

microtherion has published new project the ChipHeadBang, that is available on Github: Design for an USB to Serial converter with ICSP header for (slow) bitbang programming, based on the CH340G chip. While this seems to work pretty well, and the CH340G can be obtained extremely cheaply from sources such as AliExpress, driver support can be a bit […]

OneRNG – an open source entropy generator

Moonbase Otago is pleased to announce its Kickstarter campaign for OneRNG – an open source hardware entropy generator: OneRNG is a USB key in the same form factor as a USB flash drive, it’s an entropy generator, it makes random bitstreams suitable for feeding to your computer’s encryption systems to make better and faster keys […]

Remaking MSR206 RS232 magnetic card reader to USB

An article on modifying MSR-206 magnetic card reader to replace RS232 port with USB by crimier: This was of high urgency, so I’ve had to suspend my usual work activities and concentrate on this project yesterday. MSR-206 is a pretty impressive piece of technology, incomparable to those cheap eBay magnetic card readers. It even includes 24V […]

Derbycon video: Making BadUSB Work For You

Adam Caudill and Brandon Wilson gave this presentation at the recent Derbycon 2014 conference in Louisville, KY, covering their hack of the Phison 2251-03 USB controller firmware to add new “features” and functionality. They focus on the Patriot Supersonic Xpress 8GB USB drive allowing it to be repurposed for non-standard uses. Adam has posted his […]
