Tokyo Hackerspace/RDTN Geiger Shield

Thursday, April 14th, 2011

Japan’s difficoult moment has challenged many Arduino users (I can count at least three different threads on the forum about geiger tube & sensors lately  1, 2, 3). As David posted some time ago, the need of an open, net-spreaded visualization of the real level of radioactivity was heavily felt by the community, also for  trasparency reasons.  This is when the Geiger shield comes in:

This is an Arduino-based geiger counter shield that makes it easy to upload data to the internet and also interchange tubes. Since it’s open source and Arduino-based, its also easy to hack this to other interesting applications.

you can follow on  [TokyoHackerspace] the all process of prototyping.

SimplenZAR Gets More Complicated

Thursday, March 3rd, 2011

Arduino sending MIDI messages to control some other geeky machinery for electronic music, on breadboard.

Lately SimplenZAR becomes a self-made shield.

Late again an Arduino is developed just to fit that shield and set the original Arduino free to for the next project. Bravo!

Nice drawings of the Arduino UNO and Mega 2560

Wednesday, January 5th, 2011

If you’re looking to make your own shield for the Arduino platform, you’ll definitely need to know where all the pins and holes are located on the Arduino. After doing a quick search, I was unable to find an accurate technical drawing of the new Arduino UNO and Arduino Mega 2560.

Using the PCB design files available at the Arduino hardware website, I created a detailed technical drawing of both the Uno and Mega 2560. The drawings are available in vector-based SVG format, but low-resolution PNG files are shown below (click for larger versions). All drawings are released into the public domain, but let us know if you find any mistakes or have any suggestions or updates.

Very Good Job guys!

Cheap Fat and Open RevisedCheap Fat and Open RevisedCheap Fat and Open Revised

Monday, November 8th, 2010

 

As you can read up from [jacob sikker]‘s thesis blog, Cheap Fat and Open project is being revised and updated.

new edition has bugs fixed from 1st version, larger screen (16×2 characters) and i’ve added an op amp with bass boost and distortion feature, design by blushing boy, AKA david cuartielles. taken from his smapler board.

a few extra design goodies have been added, like walkman-like volume control, and a pixel ghost for extra prototyping.

i am only making 25 pcs. some will be sold at piksel, some at MFRU. pre-order yours today!

thanks to david gauthier for helping out with the more tricky parts of eagle CAD.

Bank 1.2 and the AT24C library for heavy data logging projects

Monday, August 2nd, 2010

A very useful project from Contesti.eu helping Arduino storing HUGE amount of data usin I2C EEProm:

Searching on the net on Arduino and Arduino web-sites you will find a lot of projects and ideas about the use of EEProm devices as a non-volatile storage method to save data. Arduino is equipped with its own – very small – EEProm memory to save configuration parameters and much more. Arduino boards have about 32 Kb – or even less – storage area and users experience the need to expand it in an affordable and robust way.

The development of a memory bank based on I2C bus EEProm relates to the creation of some kind of software in order to offer at least the possibility to access every memory location regardless of the number and kind of physical devices actually used. Following this way, we developed this memory Bank, aka EEProm 128×8 in respect of these requirements. After having carried out tests and made changes to the first hardware prototype, we are now releasing hardware version 2.1, part of the Bank project 1.2

The future of Arduino

Wednesday, July 21st, 2010

Chris Anderson met Gianluca and Massimo last week. He wrote a wonderful post full of pictures about the future of Arduino (see alco Arduino Blog) and the arduino PCB production.

A week ago I spent a day with the Arduino team in and around Milan (production lead Gianluca Martino at left above, with raw Arduino PCBs coming off the fab). Here’s a quick report.

First, we talked a lot about the Punto Uno (“Version 1.0″) release. It’s kinda incredible that Arduino is still described as Alpha software and stuck in decimal versions after all these years. Well, no more. In September, it will finally be released in a 1.0 version.

In italian, Punto and Uno is two name of different FIAT cars ;). He obviously means Uno Punto Zero, which is 1.0.

5-volt USB Breakout board

Tuesday, May 25th, 2010

I actually made this back in February (you can see the date etched next to my initials on the board), and never got around to posting about it.   It’s a super simple breakout footprint for a USB mini type-B port.  I wanted to make a really simple way to power my breadboard, and since my computer is usually on my work table, this seemed like a great idea.  I made about 60 of these tiny boards which measure about 2cm x 3cm and hope to sell them as a really cheap, tiny kit one day.

Open Source Circuit Boards using RepRap Technology

Monday, March 22nd, 2010

You you have ever wondered how to make double sided circuit boards at home and without all the chemicals, here’s the video for you. There is a big effort to increase the number of parts the RepRap can make for itself. why not circuit boards?

[...]…I couldn’t wait. For the last six months I have been building a larger, tougher, cnc / mill for milling circuit boards. The printed part count is low. I was only able to print the bearings and motor couplings. However, it is still a RepRap in spirit… if I can be so bold. The electronics are Gen 2, with an Arduino at the heart, and the firmware and host are variants of the RepRap firm and host.

After finding most of the ways not to do it I am finally getting high resolution, repeatable, double sided, drilled and scored, boards. Here is an opto endstop 2.1 board that recently came off my “tough” cnc.[...]

1st Arduino ever

Saturday, March 20th, 2010

Some interesting reports of the Opening Hardware workshop @ eyebeam in NYC with the most influential people in open source hardware including Limor Fried, Bunnie Huang (Chumby), and the Arduino team. In the first picture you can see the first Arduino ever brought by Massimo Banzi.

Celebrate.
