Xbox 360 Controller On NES

Some may think that linking an Xbox 360 controller to an original NES console is overkill. [Francois] would not count him self among that group. When the robotics team at his school was done using the controller with one of their projects, [Francois] used a Cortex M3 processor to get it to run with one of Nintendo’s 8-bit consoles. Part of the code for using the controller with the robot and the NES is available. Now all that is left is being able to play Duck Hunt with a Sixaxis controller.

Serial Hacking With An ATtiny2313

board

[Sprite_tm] automated a portion of serial hacking by sniffing out the baud rate using an ATtiny2313 and FT232 breakout board. The firmware assumes 8 data bits, no parity, and 1 stop bit (8N1). This is pretty much defacto among serial ports so it should work well, though some devices do use different settings. The auto detection routine can sniff rates as low as 110 baud and supports non standard rates. Released under GPLv3, the software is also supplied in hex format.  [Sprite_tm] has provided great project in past such as Working with VFDs, Controllable bristlebot, and AVR boost converter. Additional information regarding serial hacking after the break.

BPSK On 433 MHz European ISM Band

August 3, 2009 by 10 Comments

main

[WaveRider] is using a type of phase shift keying called BPSK to transmit digital sound and video for remote telemetry. Though a higher signal to noise ratio (SNR) is generally sought after with communications, legal limitations are imposed on total radiated power. To balance the two headed beast, he opted out on frequency shift keying due to binary shift keying’s ability to work with lower SNR. This adds the difficulty of properly reconstructing the digital signal at the receiver. A PLL based carrier regeneration circuit is used to reconstruct the signal. Using the Rabit2000 processor as the host controller on both transmitter and receiver, 96KB/Sec serial data is obtained. On the other side of the spectrum is the Homemade regenerative tube radio.

1wire Attic Cooling

[RagingComputer] built this 1-wire attic cooling fan. He’s using an Ubuntu server loaded with OWFS to control everything. The 1-wire temperature sensor is interfaced using USB while a serial x10 module sends out commands to be received by another x10 module near the fan. Back in the day we had covered a linux home automation project. We also covered HVAC hacks such as the smart attic fan and a 1-Wire HVAC monitoring system.

1-Wire HVAC Monitoring System

1-wire hvac control

The 1-Wire HVAC monitoring system is for residential Geothermal HVAC systems. This project utilizes the so called 1-wire temperature sensor. A single board computer handles the brunt of the work including web accessible trend data. With access to the underling temperatures, the over all system performance may be gauged. Earlier this year we covered a HVAC web enabled monitor that adds an element of control. As the industry adopts modern control architectures, we hope to see more HVAC hacks around.

Greenhouse Guard

[Seth King] sent in his latest hack where he used an Arduino to regulate various aspects of a greenhouse. He has sensors for soil and air temperature as well as light and moisture. He built a custom circuit that uses relays to power fans, lights, and heaters. Using timers and the sensor data, the devices can be triggered to create the perfect environment for sprouts. He hopes to make the whole thing wireless by integrating XBees, but for now he ran a USB cord to his computer.

4D Systems Micro Drive

4D  Systems micro drive provides both raw and FAT level access to microSD cards. The module contains a dedicated host controller that transforms what may be an otherwise intimidating card spec into a group of simple serial commands. With a wide supply range of 3.6-5.5 and .1″ lead spacing, this should be cake walk to tinker with. The device doesn’t support FAT32 yet. According to the GOLDELOX-DOS command set page 9, “FAT32 is currently not supported, if you mount a FAT32 formatted disk, you will not be able to access it at all, both FAT and RAW commands will fail”. At the moment the device seems limited at 2GB FAT16 partitions. This sure does seem like cheating after implementing SPI and Nibble mode SD card protocols.
