USB Bit Wacker-18F2550 - This is an easy to assemble,
through-hole version of the popular UBW board. This is a spectacular
little development board featuring the PIC18F2550. Based on the work of
Brian Schmalz, the UBW is a small board with a command interpreter for basic
input and output control. When attached to a Windows/Max OS X/Linux
computer, the UBW will show up as an RS232 Com port! You control the
individual I/O pins on the PIC through simple serial commands. This is
a kit and includes a pre-programmed 18F2550 and both male and female
connectors so you can choose which connector you would prefer. ….(design

USB Bit Whacker-Simple USB input/ output device - The UBW board is a small
board that contains a Microchip PIC USB-capable microcontroller, headers to bring out
all of the PICs signal lines (to a breadboard for example), only costs about $15-$20
to build and is powered from the USB connection. I designed this board to be a simple
parallel port replacement tool for Bruce Shapiro for use in his bits-to-bytes-to-bots
class. Apologies to all other 'Whacker' projects like EDTP's Packet Whacker for
stealing a great name . All tools used to design this project are free, and the design
is open to anyone to use for whatever they wish. Please build your own and improve
upon it! ….(design added 11/08) |

USB Data acquisition with PIC18F4550 - This project is simple and small
component count USB data acquisition or USB DAQ. The main core of USB device is
PIC18F4550 .The firmware for PIC modified from Microchip CDC library. When connect
this USB Data acquisition with PC then windows ask for driver after driver
installed(only first time) you will have a new COMx if not connect the COMx not create
by Windows. ….... |

USB DS1820 PC Thermometer - This is a digital thermometer based on USB
PIC16C745 microcontroller from Microchip and DS1820 sensor from Dallas Semiconductor.
Temperature readings are sent over USB port in HIDCOMM USB mode to VB6 program on a
PC. Hex program and sample Visual Basic 6 application is included. ….... |

USB FM Transmitter MAX2606 - This MP3 Player FM transmitter can be used to
listen to your own music throughout your home. The transmitter circuit use no coils
that have to be wound. When this FM transmitter used in the car, there is no need for
a separate input to the car stereo to play back the music files from your MP3 player.

USB I/O interface board for PC - (electronic circuit added 2/07)

USB iPOD Charger - The circuit's pretty simple, basicly it's just a voltage
regulator. Both the LM317 and the REG1117A (LDO) fit the PCB, maybe there are even
more types that I'm aware of that can be used on it. I did add one extra thing: a LED
that shows if the connected device is consuming power. To do this I used a shunt
resistor and a current converter. I choose 0.2 ohm for the shunt, since it's not hard
to come by and should only drop 0.1V @ 500mA. Either an INA168 (current output) or an
INA193-198 (INA194 is best in this case) (voltage output) will fit as current
converter. The trip point at which the LED should start to burn can easily be adjusted
by one resistor (in case of the INA168) or by two (in case of the INA193-198). In the
schematic it is set at 100mA using an INA168 using a 950k resistor. The Schmit buffer
is a Texas Instruments Little Logic chip (1G17). ….(electronic schematic added 11/08)
