When working on 20×4 (or bigger) lcds font dimension can become an interesting issue: [liudr] shared & updated its Phi_Big_Font library The Phi_big_font library utilizes 3 X 5 dot matrix technique I developed to display characters 6 times the size of ordinary characters seen on HD44780-compatible character LCDs. You will need two rows and 4 […]
Arduino Forum User [UnaClocker] shared a cool hack on its Maytag dishwasher: 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 […]
As seen in the streaming of Google IO 2011, physical computing and interactive enviroments are one of the main topics opening the conference. The Android Open Accessory Kit is going to allow Android related devices receive data from different sensors (just via USB, for now). The Android Open Accessory Development Kit (ADK) provides an implementation […]
As [Kalanda] published on its blog (spanish) and github, there is one more (easier) way to establish connection with an Arduino over a network connection (among the others): serial2socket-proxy is a cross-platform software application developed in Processing for creating a virtual connection between the serial port and a network socket port. For example, you can […]
Some time ago [ant.b] from the Arduino Forum manage to reflash the Atmega8u with other LUFA Firmwares. [Dimitri Diakopoulos] has recently developed a similar approach for his HIDUINO project. Very good explanation & references. Diakopoulos succeded to make Arduino show up as a MIDI Device: LUFA powers the HIDUINO project in that it handles most […]
A step-by-step guide on controlling physical things (like grabbing candies with a mechanical arm) via Internet (please, try!). In this instructable you will learn how to connect to your arduino and control it over the net, set up a video stream, and how to control stuff with your arduino all in realtime. I’ll try to […]
[pabloxid] shared an Hexapod project on the forum based on an Arduino MEGA 1280 and 18 Dynamixel AX-12 motors: SAMSA is based on the Wiring board, with an ATmega128 microcontroller, and SAMSA II on the Arduino Mega, with an ATmega1280. Both are pretty similar, tough the ATmega1280 has 8 KB SRAM, twice the ATmega128. For […]
[Mark Fickett] shares a nice solution to keep track of pils and medecines his mother takes. When taking her battery of medicines, my mother occasionally loses — or, lost — track of which ones she had already taken. This aims to keep track of what’s been taken (and how recently); and also to provide a […]
[Michael] posted some interesting uses of Nootropic’s latest shield, the Video Experimenter Shield, besed on a LM1881 video sync separator to detect the timing of the vertical and horizontal sync in a composite video signal. It’s one of the few examples of Arduino processing a live video signal, as previously seen with the Eye Shield […]
[Alex] collects retro gaming consoles. One day while playing a SNES title, his save games got wiped when he powered off the system. It turned out that the battery inside the game cartridge got disconnected somehow, and it got him thinking. He decided he wanted to find a way to back up his save games […]
