Game Boy Advance Rapid Fire Hack

Are your hands cramping after playing your favorite game on your Game Boy Advance? Have a look at this Game Boy Advance Rapid Fire Hack by the Hackers Workbench to give your fingers a break. This circuit will simulate you tapping the B button for all you’re worth. The other nice thing about the design is since there only a few components you can just dead bug it right inside the game.

Thanks William.

“Parts list:
(1)Dual two input nand gate IC (I used a triple three input NAND gate IC because it was what I had on hand)
(1)2n2222 NPN transistor
(1)0.1uF ceramic capacitor
(1)Mini momentary on switch from a computer mouse, or similar
(1)1M ohm resistor (the value of this resistor can be mucked around a bit)
Some thin wire”

DS1821 Thermostat

at 1:48 pm. Filed under DIY Hacks, Electronic Hacks

ds1821-thermostat


Over at Karosium there is a DIY DS1821 based Thermostat project. The code is available and I am assuming if there are some requests that the schematic will also be posted. 

“After configuration for thermostat mode the center (1Wire DQ) pin becomes a thermostat output pin. Since it’s still an open collector pin it needs a pull up resistor, and since it’s still basically a 4mA GPIO a transistor at least is needed to switch anything meaningful with it.”

PIC18F452 based Rover Robot called GUI Bot

pic18f452-based-rover-robot_2


Rustic Engineering has some good posts about the GUI Bot build, it’s a robot that is based on the PIC18F452 microcontroller. The robot looks great with two large drive wheels and one coaster wheel under the front. You can also find a large writeup of the project over at Lets Make Robots.

“Feature List

  • Move, turn and gyro with speed and agility;
  • Speed up and Stop when you need;
  • Generates little sounds/alerts (and some music too, like a old cell phone);
  • Detects and follow a black line over white plane;
  • Easy programs changes, via USB/Serial adapter connection and a bootloader on the microcontroller;”

Ding Dong, you have mail

ding-dong-you-have-mail


David from uC Hobby had a wireless doorbell but the remote was lost, instead of tossing it in the garbage he re-purposed it. By adding a few components to allow a small signal to activate the chime coil this can now be used by almost anything electronic as a cool indication. I would have used it to ding dong when I had a new email but David decided to hook it up to a Linux box to ring whenever someone mentioned uC Hobby on IRC. Goes to show that almost anything can be made even cooler than the original purpose. There is code posted so you too can make your own internet door bell.

Single String Servo Guitar

Keith Baxter from the The Milwaukee Servoelectric Guitar Project sent in the cool progress he is making on the Single String Servo Guitar project. You probably remember Keith from the original Servo Guitar that we featured last year. There is something haunting and pleasant sounding with this new single string guitar, I wonder if Keith could rig something up so that it could pick the string and control the servo so that it could play a tune all by itself? If you are interested in making your own there are full schematics available.

“This design uses two Arduios, a first Arduino that receives MIDI data and interprets it to a note within the one octave obtainable by the string. The second Arduio converts the note number to a tension of the string, allows tuning of the string (adjusting a table that converts new to string tension) and handles the control algorithm for the servo motors. For a four string design, three Arduinos would be used, one for MIDI decoding and two each handling two strings. The servo amplifier is the same as used in previous designs. This design also provides autotuning to slowly correct any string drift over time. The autotuning uses a variation of autocorrelation called average magnitude difference to detect string tuning opportunistically between notes.”

Motoduino – DIY Motorcycle Computer

Check out this sweet motorcycle GPS and temperature display that came out of HeatSync Labs (cool name by the way). Nice thing about the system is that it could be modified to monitor all sorts of motorcycle sensors.
