          • Programming the Square Inch - TQFP Jig

            Read more at: http://thecustomgeek.com/2012/08/17/programming-the-square-inch-tqfp-jig First, I am happy to announce that the One Square Inch of Goodness and the FTDI Adapter are in the stock now and available for purchase! In the video above, I show how I programmed the assembled kits as well as the raw TQFP IC's without soldering anything to them. It's a pretty simple setup, but solved the problem I was facing as well as made things a lot faster. As I mentioned in the video, pogo pins are found here, USBtinyISP here, and breadboard switch here (from Adafruit). A note on using ICSP: - The Square Inch is designed to accept an FTDI connection for programming. Because of this, a .1µF capacitor is between the reset line of the ATmega328P and the pin labeled DTR. This is so when you load new sketches on the Square Inch, it will reset automatically via the DTR line on the FTDI adapter. When you use ICSP, you need to bypass this capacitor! Otherwise it will not work. The programming board I used in the video had the capacitor bypassed with solder (pictured below). There is also a via to the right of the capacitor that leads to the reset line. This can be shorted to the DTR pin to accomplish the same task, as I did to program the assembled boards. On the assembled boards, if you wish to change the bootloader or upload sketches via ICSP, you can temporarily short the cap using tweezers on the cap itself (green arrows) or the DTR pin and the via leading to the reset line of the 328 (red arrows) as shown in the picture below.

OpenWrt is the software platform and the Ben Nanonote is the physical development platform for the Qi Hardware project. (...) (wikipedia) Qi hardware, also called Copyleft hardware, is hardware that attempts to apply the Free Software Foundation's GNU GPL concept of copylefting software to the hardware layer. The project is both a popular open hardware community websites and a company, co-founded by Wolfgang Spraul and Yi Zhang, that makes hardware products.

              • Small(s) GPS


                from Jeremy Saglimbeni Added 9,181 5 1

                Read more at: http://thecustomgeek.com/2012/07/15/really-smalls-gps/ Hi peeps, I have been wanting to make a small GPS device (GPS receiver and some sort of screen) that I could carry around for a while now, but I didn't want it to be too big, so I made this. Mission accomplished. This unit is explained in the video above, but is basically a GPS receiver, 1 CR1220 battery for the RTC on the GPS breakout, one of my Square Inch of Goodness boards, one 128x32 OLED display, three 6mm buttons, and a 400mAh Li-Po Battery (from Sparkfun). It even has FTDI headers on it so I can update the firmware with ease (with my own FTDI adapter!). The awesome part is that all of those things fit in an Altoids Smalls tin, measuring 2.15" (W), 1.35" (L), and .56" (H), or 55mm (W), 34mm (L), and 14mm (H). The GPS breakout board is from Adafruit and uses the MTK3339 GPS module, and man does it work well. I have had other GPS modules that worked, but it was a fight. If you're thinking about putting GPS in a project, use this. They also have a great library for it. They even have the raw MTK3339 GPS module if you want to use your board. Read the Adafruit product page for all the features, there are many. The 128x32 OLED display is also from Adafruit, it works well and has the typical OLED crispiness. Very easy to read, even in sunlight, for the size and you can even multiply the text size if you want to. So I'm going up to NY in a few days, and I wanted a new and exciting way to talk with the TSA folks, so I figured this would work. (kidding) If only Hollywood had not trained everyone to think a gadget with a few wires and a flashing red LED, that they didn't understand, was a bomb.. ugh. (not kidding)

                • One Square Inch of Goodness


                  from Jeremy Saglimbeni Added 1,880 0 0

                  Read more at: http://thecustomgeek.com/2012/07/09/one-square-inch-of-goodness/ So a while ago I discovered that I needed a microcontroller in a really tight space. I tried an ATmega328P PU (DIP package), but try as I may, It would not fit. The answer? The ATmega328P AU (TQFP) this is a much smaller package, and for the added bonus, it has 2 extra ADC's. This a great little board to squeeze in various projects, and opens the door to some very cool stuff I have coming up. Some of you might remember I put this board in a project I did a while ago when space was very limited. It's just a handy little board to have on hand. :) Links to files are on my site.

                    Read more at: http://thecustomgeek.com/2012/07/03/serial-or-speed/ This video demonstrates the speed difference between serial enabled/disabled on an Arduino Uno while toggling a pin output. Just a really simple test of how fast it can pull a pin high and low (without using direct port manipulation), with and with out serial enabled. I think that was the smallest Arduino sketch I ever wrote..

                      from Debbie Davies Added 20 0 0

                      Homecamp brings together members of the technical community interested in using open systems and low cost, often re purposed hardware to bring around a positive change in the way we use energy and appliances around the home. With ever increasing energy prices the race is on to develop ways to utilize smart technology to help offset domestic energy consumption and lower carbon footprints. Homecamp 4 invites those working with technology, whether software, hardware or web based applications to meet at an informal "unconference" in central London to offer presentations, workshops, mash-ups and hack sessions with the aim of sharing information and furthering the development of the open energy community. Of the four presentaions that day we hear from Ken Boak - inventor of Nanode. www.nanode.eu Nanode - an Open Hardware Success Story - Ken Boak, Arbour Wood Ltd.
