Seeed Studio video channel
Seeed Studio has started posting videos. This week they demo the Rainbowduino Cube, a color 3D LED matrix based on the Arduino. Mandarin is spoken, with English in subtitles. This is an idea Eric from Seeed mentioned when were on the subway to NYC Resistor this summer. If you’re learning Mandarin with Adafruit these videos […]
NEW PROTOTYPE: USB & serial LCD backpack
Small character LCDs can show new mail stats, system performance, news feeds, and more. The USB and Serial LCD backpack connects HD44780-compatible character LCD screens to your USB (or serial) port. Almost every open source hardware shop sells some type of serial LCD backpack. Our goal is to build an update to the classic serial […]
Dangerous Prototypes on Google+
Google+ introduced pages for organizations yesterday, you can now add +Dangerous Prototypes to your circle. You may have already added +Ian Lesnet in the past, but it looks like we can’t migrate the accounts.
Dangerous Prototypes source code visualization
See two years of source code development in a 6 minute visualization. Tayken used a script to visualize code development in the Dangerous Prototypes SVN repository at Google Code. Watch for the 2 big reorganizations, one in 2010 and again in 2011. In the beginning there’s a single long-term contributor, but around 2010 the number […]
Open 7400 competition winners
Thank you participating in the Open 7400 Competition. All the entries were amazing, check out the full list here. Four judges, Dave Jones from EEV Blog, Jayson Tautic CEO of TAUTIC ELECTRONICS LLC, Marc Alexander from Freetronics, and Dino Segovis from Hack A Week, and Ian from Dangerous Prototypes each made a top ten list. The […]
Home Camp: Dangerous Prototype’s presentations
Here’s a .zip file with our presentations from Home Camp 4. Day 1: open hardware manufacturing, and day 2: using the Bus Pirate with I2C EEPROMs.
Home Camp: Nanode internet radio
Andrew’s internet radio based on a modified Nanode network platform. An AVR microcontroller uses an ENC28J60 ethernet chip to grab MP3 feeds from the net. Packets are stored in a ring buffer in a 32K serial SRAM chip. The buffer is fed to a VS1033 MP3 decoder chip. All of the chips are controlled from […]
Home Camp: Ciseco energy and control wireless serial links
Ciseco energy and control demonstrated several different wireless serial links based on a CC1110 433MHz radio + 8051 processor chip from TI. The modules can be used for serial communication with an Arduino (or any board), and are capable of over-air remote updates using the standard Arduino bootloader. The project is not yet open source, […]
Home Camp: wireless Open Energy Monitor
Trystan and Glyn from the Open Energy Monitor project presented a 100% open source home energy monitoring platform based on the Nanode. Wireless sensors collect data and send it via radio to a RF->ethernet base station. The base station saves the data to a server, either the Open Energy Monitor’s servers or a self-hosted copy. […]
Home Camp: The Nanode
Ken Boak discussed the Nanode Arduino-based network node. The Nanode is an all through-hole network development board, designed specifically as a home monitoring and automation platform. Firmware built in the Arduino IDE using open source libraries reports statistics to Pachube, a website that shows real-time data from small internet devices. The hardware combines an Arduino […]
Home Camp 4: Summary
Home Camp is an “unconference” held in central London. The goal is to increase environmental sustainability in the home using technology, a mix of closed and open source projects were represented. This weekend we saw first hand what it’s all about. Day 1 stated with a keynote by Moixa Energy about a home solar power […]
7400 Competition: An ‘open source’ open source competition
