Raspberry Pi supercomputer

The crew at the University of Southhampton have been working on a Raspberry Pi based supercomputer. “The machine, named ‘Iridis-Pi’ after the University’s Iridis supercomputer, runs off a single 13 Amp mains socket and uses MPI (Message Passing Interface) to communicate between nodes using Ethernet. The whole system cost under £2,500 (excluding switches) and has […]

Testing the new reduced-sized ICSP connector

This week we received a batch of PCBs and amongst them was the latest revision of our USB TFT breakoutboard. This board is the first board that features a new ICSP footprint, which occupies less space on the PCB and should improve testing and programming times at Seeed.

Replace vintage computer hard drives with a CF card

J1mbo updated his XT-CF adaptation of our XT-IDE CPLD board. You can check out his wiki page with all the details about the board, the BOM, and the source files. This board allows vintage XT computers to use CF cards as hard drives, which keeps lots of old industrial and medical equipment going using modern […]

Levitating LED combines wireless power transfer + magnetic levitation

Chris Rieger is an Electrical Engineering student from the University of Queensland Australia, and has been experimenting with wireless power transfer and magnetic levitation. After studying the work of Jeff Lieberman, Eric Taylor, and others, Chris fine tuned his design to combine these two technologies to achieve the results depicted in this video. Visit Chris […]

Nutshell: Netduino Go Touch Display visual designer

[nwazet has developed Nutshell, a visual screen designer for their Netduino Go Touch Display module. It’s purpose is to make the design of Netduino display module UI’s easier and more intuitive than coding it up line by line. You can use Nutshell without installing anything since the tool runs JavaScript in your web browser. Just […]

SNES FLASH/ROM runs custom Super Nintendo code

dext0rb from The Electrified Fooling Machine Company has just finished work on a project which allows custom Super Nintendo code to run on an SNES FLASH/ROM. He writes, “I wanted to make and play an updated version of NBA JAM an SNES hardware, so I made this device. Load a game ROM to the device […]

ATARI POKEY player using DP QFP proto board

Markus Gritsch has built a dedicated ATARI POKEY chiptunes player using a DP QFP proto boards. “I successfully compiled the ASAP (Another Slight Atari Player) library for a PIC32MX795F512H. ASAP emulates a 6502 CPU and the famous POKEY sound chip used for example in the ATARI 400/800 and XL/XE 8-bit computers. To say it with […]

Update on the Little Wire AVR programmer

Little Wire is a ATtiny-based open source AVR programer, we wrote about it previously. This project should soon be available at Seeed Studio in kit form.  Here are some updates since our last post: I finished the C and C++ libraries. I created examples for C and C++ , doxygenreference page for C++, documented and […]

Chaotic Moon Labs’ Board of Imagination

At CES 2012 Chaotic Moon Labs debuted the Board of Awesomeness, a motorized skateboard which was controlled based upon readings from a Kinect. Now the CML crew has taken the concept one step further with their Board of Imagination. The BOI is similar to the Board of Awesomeness except that control is based upon brain […]

Driving two character LCDs in parallel

Abdullah explored the idea of driving two character LCDs in parallel. When he couldn’t find any information about this online, he decided to try it out himself. Then I thought about it and I gave it a go. The result is positive! However, there is a gotcha; if you are using LCDs from different manufacturers […]

Peacon XT 8 bit bus to CompactFlash adapter

J1mbo finalized his XT-CF adaptation of our XT-IDE CPLD board. You can check out his wiki page with all the details about the board, the BOM, and the source files. This board allows vintage XT computers to use CF cards as hard drives, which keeps lots of old industrial and medical equipment going using modern […]

Human birdwings project: the only thing real was the Seeeduino

UPDATED: The Human Birdwings project is an elaborate hoax, the brainchild of possibly one Jarno Smeets, an alleged mechanical engineer from the Netherlands. His stated goal was to build a set of functional human birdwings similar to those conceived by Leonardo Davinci. Tinito was watching the above installment from the 14-video series and discovered that […]

XT to IDE hard drive controller development update

J1mbo designed some digital logic upgrades to the XT to IDE hard drive controller. This board enables you to use IDE hard drives with vintage XT computers. His design increases the write speeds to the hard drive. As promised here’s my schematic that should provide for fast writes with the DPv2 board. The command trigger […]

Introducing RTL-SDR: a $20 SDR

If you don’t want to spend $1,200+ for a USRP SDR to use GNU Radio the crew at OsmoSDR want to help. In addition to their other amazing work, Osmocom team members (notably Steve Markgraf) have been hacking away on an alternative least-cost solution they call rtl-sdr. So what is rtl-sdr? It is a creative […]
