Low-Power, 8-Channel, 24-Bit Analog front-end for biopotential measurements

The  TI ADS1298R could be perfect for that EKG project you dreamed of. It has a 8 analog to digital converters with programmable gain amplifiers, an internal reference, and a clock source. The ADS1294/6/8/4R/6R/8R incorporate all of the features that are commonly required in medical electrocardiogram (ECG) and electroencephalogram (EEG) applications. FEATURES Eight Low-Noise PGAs […]

App notes: RGB LED driver reference design

An introduction to RGB LED driver reference design for a low-power projector. This application note is an RGB LED driver reference design for a low-power projector. The design features a single MAX16821 HB LED driver to drive the RGB LEDs one at a time. This approach reduces the components needed, resulting in an efficient, small, […]

Arduino used for ThinkPad password recovery

The Seeeduino is being resold as a ThinkPad password recovery tool: the only Affordable Fully Assembled, Programmed and Tested unlimited use USB based ThinkPad Supervisor Password Recovery or Clear Tools in the world. Joe’s KeyMaker KMX1 can Recover or Clear Supervisor Password from all current ThinkPad models with the exception of the SL400 and SL500 […]

Arduino logic analyzer with Logic Sniffer client

gillham wrote a logic analyzer firmware for the Arduino that works with on the Logic Sniffer client: Reading through the SUMP docs the protocol looked simple enough that I thought “Why not try implementing this on the Arduino?” and set about it. After getting my code to respond appropriately and kind of working with the […]

PROTOTYPE: xQFP protoboard with SOIC, SSOP, 0805 footprints

Today we’re super excited to announce a new QFP prototype board for SMD parts, the newest addition to our Dangerous Protoboard collection. This giant protoboard has a xQFP breakout footprint, along with a score of other pads for SMD parts. Great for getting started with a new microcontroller. Dangerous Protoboard: xQFP. Prototype board for working […]

Handheld RF spectrum analyzer now available

Seeed has a new handheld RF Spectrum Analyzer designed by Arocholl: As wireless communication devices grows in use everywhere, so it does the need to monitor, test and diagnose them. RF Explorer is an extremely affordable Handheld Spectrum Analyzer designed from scratch to be a sort of Swiss Army Knife for the specific needs of […]

FTDI VNC2 Vinculum II toolchain issues

Lots of people have been experimenting with the new FTDI Vinculum II USB host chip. We covered the Vinculum II board here and here. It looks like the hardware and firmware are still a little rough. jpieper has documented a number of bugs, including issues with interrupts and the compiler. If you’re starting a new […]

Serial port only Bus Pirate v3b update

schazamp has another update on the serial port only Bus Pirate. I have released BusPirate-v3b-FTDI-0.3, which has: * room for a shrouded I/O header * Sparkfun’s locking header rows * more clearance around voltage regulators, for easier assembly * improved label size and positioning You can find the zip distribution here Or check here for […]

ITead Studio Colorduino preview

lincomatic wrote a review of ITead’s Colorduino, and also released an Arduino library that works with both the Colorduino and Itead’s Arduino RGB Matrix driver shield. ITead Studio kindly sent me a Colorduino for beta testing. The Colorduino was inspired by SeeedStudio’s Rainbowduino LED Driver Platform. Its form factor is very similar to that of […]
