2.8 TFT Touch Shield for Arduino. Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (2.8″ diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240×320 pixels with individual pixel control. It has way more resolution than a black and white 128×64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

The Mosquino is a new Arduino variant, designed to work with much lower-capacity power supplies than the standard USB/7805 5 volts, such as those delivered by solar cells or small batteries. While it isn’t physically shield compatible with the Arduino, it does boast some unique and useful features, such as:
- compatibility with the Arduino toolchain and portable IDE
- power supply shields — effectively giving you multiple, easy-to-swap PSUs while keeping your program and digital circuit hardware intact.
- uses an ATMega644, which provides twice as much program memory as the ’328.
3 (three!) Mosquino-compatible shields can be connected at once without stacking, due to redundant pinouts.
prioritization of power supply (USB > battery).
- FTDI operates from isolated power line, so no draw on circuit when the computer isn’t connected.
- hardware real-time clock and 3 interrupt lines, to encourage event-driven operation and programming.
- 0.1″-grid pinout for shields so you can develop on perfboard.
- still fits in an Altoids tin.
Mosquino is based on the Sanguino design using the Atmel Atmega644PA and family microcontrollers. It turns out the name Sanguino literally translates as “bleeding”! In keeping with the theme, this parasitically-powered board is a “little bloodsucker”. Don’t worry, it doesn’t drink much. (Also, the name Draculino is already used.)

I have obtained two Silent Radio LED signs on Ebay and I intend on rebuilding them. To get one of them apart I had to reach through a hole in the back and cut the wires to the power transformer. To remove the logic board I had to use pliers on the screw head and pliers on the mounting shaft. In one case the screw broke off rather than come out. Tin sheers or heavy duty wire cutters can be used to remove the connectors between the sign and the logic board.
Tinkerer and author John Graham-Cumming (he wrote the Geek Atlas) created an Arduino-based gaming system that fits in a can. [via]
On the left is the main controller (the power switch is visible) and on the right is the expansion controller with its cable. The left (red) controller also has a ‘fire’ button that isn’t visible and both have simple ‘paddle’ style controls.

The gang at SinnerSchrader have combined their love of foosball and their passion for digital solutions to make the world’s first digital foosball game. The project uses optical sensors to detect the scoring of goals. These sensors are read with the Arduino which sends it over WiFi to the server which then makes it available over the internet via mobile Webapp and on their agency foosball league’s webpage.
They promise that the source code will be published on their site very soon.

The control panel on the front of it died, it failed from corrosion getting into the laminated plastic PCB that it’s made up of. Not really repairable, just meant to be replaced, except that it’s a $150 part. From what I could find online, it seems to be a common failure, so why buy an overpriced part that’s just going to fail all over again?This is one of the things I love about the Arduino, it allows me to consider alternatives that I’d have NEVER been able to consider before. If I had to program a controller in assembly, or flat do it with just discrete chips, I’d have never considered this as an option. But with the Arduino, not only can I build my own controller, but it’s almost stupidly simple to do.
