ZPUino is a system-on-chip 32bit microprocessor FPGA core, that functions with a modified Arduino IDE. All the files regarding the core are open-source and downloadable from their site, and so is the modified Arduino IDE. [via]
Yes, that is true.
ZPUino 1.0 is now available for you to use and enjoy. Expect some updates on next few days – release cycles are about to change, we’re switching to release early, release often. As always, direct any questions to zpuino @ alvie.com.

Mint-Sized Success Meter (quit smoking!) with Arduino – [via]
There comes a time in life to put childish things behind and give up nasty habits. Some, like smoking, can be damn hard without constant encouragement. It was time for me to combine my favorite hobby with my driving goal and make this: The Quit Success Meter!

Measuring Battery Capacity with an Arduino. Dennis writes- – [via]
I needed a couple of AA batteries and found the display at the supermarket where they were all arrayed. Normally when I’m shopping in the supermarket, I tend to look at the price/kg or price/l when comparing similar products. In the case of the batteries, there was no such indicator. Fine, I thought, I’ll work it out myself. I grabbed a few different makes and scanned the packaging for some measure of their capacity. Nothing. Not a single one of the batteries had any indicator of how much energy they would provide. Instead, they all had terms like ‘PLUS’, ‘SUPER’, ‘ULTRA’ and of course had wildly differing prices. So, I decided that it was time for an experiment and bought one pack of every type I could find.

This how-to takes you through all the steps of making your own arduino on a perfboard or perfduino! Arduino microcontrollers are great for learning about physical computing and are very useful for rapid prototyping. Arduino’s simple programming language makes it a favorite of hobbyists and diy-ers around the world. Because arduino boards range in price from 30 to 70 dollars, it can be very cost effective to make your own. This lets you customize the layout of the board and brings down the cost so you can embed your perfduino in a final iteration project without losing your precious professionally made arduino board you had to wait so long for by the mailbox. The perfduino in this tutorial is designed to closely mimic the original arduino functionality without any specific project layout in mind.

The Ard-Vark is a basic electronics box that can be remotely controlled by an app on your iPhone, iPad or Android phone. It is Arduino compatible. Have you ever wanted to build a project that needed electronics but you didn’t know how to start? Would you like to add motion to one of your creations, and be able to control it with your phone or tablet and not have to learn electronics, soldering, programming and a few hundred other things? Then the Ard-Vark is for you.

swim with a triathlete group in an outdoor pool at 6AM three days a week. For half the year I can see stars when I start swimming. What I can’t see in the dark is the analog clock to check my pace on 100 meter laps.
To solve this problem I designed and built a portable digital timer with LED display. The 4-digit 7-segment display is large enough to see from 10 feet away so I can read it without stopping. The timer is encased in a transparent and waterproof polycarbonate tube so that I don’t have to worry about it getting wet or falling in the pool. In fact you can take it to the bottom of the pool and it won’t leak. Normally it just sits on the edge of the pool where I can see it.
There are a variety of LCD swim timers available that are fine for day swimmers. This timer is for night swimmers.

This is the fraAngelico synth by Standuino. He writes – [via]
FraAngelico 8-bit PWM digital synth is unique by the means of its sound generation. It does not use any D/A convertor but the sound is generated by just one digital output pin using Pulse With Modulation which means that by fast changing of different lenghts of pulses we can make different output voltages. Resolution of this technique to achieve different voltage levels is 8-bit but in the true essence the output form the synth is just 1-bit because the output pin does jus 1 or 0 which makes distinctive digital character to its sound.
Although this puristic and minimalistic approach to sound generation, FraAngelico is able to make wide range of different sound colours from powerfull bass to glitchy noises as well as complex rhithmic structures.
This unprocessed raw digital output can be also synchronised with any MIDI device through its MIDI input. To connect standart midi cable use the Standuino MIDI conector (coming very soon) or see tutorial how to connect more standuino devices to you soundcard (coming soon).

This is the eagerly awaited 3.0 version of Photoduino. Photoduino is an open source camera controller based on the Arduino platform which you can use to automatically take pictures with your DSLR camera.
It serves as technical support for shooting high speed photos but you can also use it as an intervalometer to make Timelapse videos or for animals and insects photography.
Photoduino is an electronic circuit that is placed on an Arduino board as a Shield taking all the inputs, outputs and power pins. It has all the necessary electronic components and connectors for connecting the camera, flashes and sensors. You can control the shutter and camera autofocus, and you can also trigger two flashes. It also has a sound sensor, a shock/impact sensor and a laser or infrared barrier that can be used to take pictures when you register an event on any of the sensors. The configuration is done entirely through a small LCD screen using only two buttons, so it works independently without the need for a computer (except for firmware updates).
This system currently supports a wide range of DSLR cameras with a remote shutter cable connector.
Both hardware and firmware are completely open (like the Arduino platform on which it is based) and it is released under an open license.

In this third blog post, I’m going to show you the logical view of my Nixie clock and two of its main elements: the real time clock, to keep track of the current time, and the expander, to add more I/O lines.
