More MAX3421E USB peripheral/host controller shields
Circuits@Home has two Arduino USB Peripheral/Host Controller shields with the MAX3421E we covered earlier. A driver is available for the Arduino, which should be portable to other microcontrollers. There are also libraries for working with USB devices, such as cameras, bluetooth devices, and simple Human Interface Devices like mice and keyboards.
ExpEYES: new open source learning initiative
ExpEYES is an open source hardware/software learning initiative from the PHOENIX project of Inter-University Accelerator Centre, New Delhi, India. It is a framework for developing science experiments, demonstrations and projects and learning science and engineering by exploration. The expEYES hardware, based on an Atmega32 clocked at 8 MHz and interfaced to the PC via an […]
MAX3421E USB peripheral/host controller with SPI interface
MichaelZ writes: While poking around SparkFun’s website I found USB Host Shield which is only marginally interesting unless you are an Arduino fan. But the USB host controller chip is interesting. The MAX3421E is a USB Peripheral/Host Controller with SPI Interface. This is an alternate to the FTDI VNC USB host controllers. It has only […]
Omnidirectional remote controlled robot
Markus shared his Omnidirectional remote controlled robot in the project log forum: Recently, I got interested in omni wheels, so I built this little robot. The robot has three pairs of omni wheels. I covered each roll of the omni wheels with liquid rubber (plastidip) to get better traction. I bought the cheapest servos I […]
Processing releases Processing.js v1.1
Processing.js is the sister project of the popular Processing visual programming language, designed for the web. Processing.js makes your data visualizations, digital art, interactive animations, educational graphs, video games, etc. work using web standards and without any plug-ins. You write code using the Processing language, include it in your web page, and Processing.js does the […]
Android as a user interface to hardware projects
Mario Böhmer at Dev-O-Rama wanted to access data from his web enabled embedded HTLPSensorNode Arduino project using his Android phone. He decided to use the Barcode Scanner app instead of a more traditional approach in order to add an artistic angle. Mario describes the theory he employed to build an Android app which takes the […]
PyMite: Python-on-a-chip
Python-on-a-Chip (p14p) is a project to develop a reduced Python virtual machine (codenamed PyMite) that runs a significant subset of the Python language on microcontrollers without an OS. The other parts of p14p are the device drivers, high-level libraries and other tools. They’ve released ports for the Microchip PIC/24dcPIC, Teensy 2.0, Arduino Mega and others. […]
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 […]
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 […]
Retro typewriter as USB keyboard
Here’s a unique project which repurposes old manual typewriters as keyboards for computers or Ipads, using an Arduino as the intermediary. It’s the brainchild of Jack Zylkin, a Philadelphia-based electrical engineer who has designed a kit that makes the conversion reasonably easy for anyone who enjoys hands-on projects. For those considering privacy and flexibility, an […]
Gameduino: a game adapter for microcontrollers
Gameduino is a game adapter for Arduino – or anything else with an SPI interface – built as a single shield that stacks up on top of the Arduino and has plugs for a VGA monitor and stereo speakers. Anyone who can write an Arduino sketch can create video games. It’s capable of the full […]
Modkit beta released
The first public beta of Modkit, an in-browser graphical programming environment for microcontrollers, has been released. Modkit allows you to program Arduino and Arduino compatible hardware using simple graphical blocks and/or traditional text code. Modkit’s graphical blocks are heavily inspired by the Scratch programming environment developed by the Lifelong Kindergarten Group at the MIT Media […]
Display custom characters on 16×2 LCDs
Chris from PyroElectro informs us of his tutorial on designing custom characters for display on a 16×2 HD44780 compatible LCD. This tutorial shows how to use the advanced functionality of HD44780 16×2 LCD’s where you can create your own characters instead of using the built-in character set, and includes a simple demonstration of animation on […]
Using watchdog timers in your AVR projects
Here’s an interesting tutorial from Embedds covering the use of watchdog timers in AVR and Arduino projects.
Capacity tester for rechargeable batteries
BrianH has posted a useful Instructables project that tests the capacity of rechargeable NiMh and NiCd batteries. The circuit is based on an Atmega168, and functions by draining the AA batteries (from 1 to 3 batteries) then computes and reports the capacity in mAh. It uses a Nokia 5510 graphic LCD to report battery condition […]
OpenPicus wireless development platform
OpenPicus is working on open source wireless hardware and a free application development platform. The current WIFI hardware has a PIC 24FJ256GA106 microcontroller, and an MRF24WB0MA module provides the wireless. An Arduino-like IDE has libraries and frameworks to simplify wireless development. If you have the grit to develop a wireless app without a proper debugging […]
OpenMT: Open source Multi Touch
Open source Multi Touch, known as OpenMT, is an open source hardware project for developing multitouch applications. Unlike camera-based multitouch, OpenMT lets you make a thin, flexible multitouch surface. It is Arduino friendly and has been developed by Sensible UI in Seoul, Korea. Users can experiment with hardware development themselves with projects such as ArduMT, […]
PROTOTYPE: Daft Punk table controller
We’re releasing a stalled or abandoned prototype every few days while Seeed Studio is on break. We put a lot of work into these projects, but they’re still missing major components and testing. If an abandoned project sparks your interest, we may have PCBs to get you started. The goal of this project was to […]
