Intelligent NiCd/NiMH Charger/Cycler with 128x64 Graphical LCD
Posted on Tuesday, April 20, 2010   •   Category: Battery Chargers

Intelligent NiCd/NiMH Charger/Cycler with 128x64 Graphical LCD

The accu cycler project presented here is an excellent solution for charging and discharging NiCd and NiMH accumulators for R/C modelers and others who make use of these accumulator types. With its performance it is very close to the many of the commercial products available on the market.




0-500MHz PIC16F876 RF Power Meter
Posted on Tuesday, April 20, 2010   •   Category: Test and Measurement

0-500MHz PIC16F876 RF Power Meter

RF Measurement has been an expensive work so far the cost of measuring RF Power Meter instruments are concerned. RF Power Meter is based on PIC16F876 microcontroller, AD8307 and 2x20 LCD display. Full documentation is included.

Serial LCD Controller

Serial LCD/VFD Controller is a HD44870 based LCD/VFD controller via RS-232. The control command is compatible with Matrix-Orbital's LCD module. So, you can use any MO friendly software to control this baby such as LCDC.




PIC NIC Ethernet Controller

PIC NIC Ethernet Controller

PICNIC is a project to add 10BaseT Ethernet controller to PIC17F877, and it can run as an network-enable device. This project is based on tristate's PICNIC product. And I just change the temperature sensor's circuits to improve the precision on A/D convert and add another Temp-Sensor channel.

USB - LCD with PIC Microcontroller & FT232

USB LCD/VFD Controller is a HD44870 based LCD/VFD controller via USB interface. The control command is compatible with Matrix-Orbital's LCD module. So, you can use any MO friendly software to control this baby. Such as LCDC... The firmware are based on David Potter's Serial LCD/VFD Display, but I almost rewrite the entire code.

DTMF Decoder with LCD Display

The DTMF decoder 2 is a useful tool used for decoding DTMF (Dual Tone Multi frequency) generated by telephones. The decoded digits are viewed on a 16x2 LCD screen.




USB to RS232 Converter

USB to RS232 Converter

Why build my own USB to RS232 converter when there are adapters already available from many suppler? The Answer is simple: Neither the strand "USB to RS232 converter" actually worked *properly* with all the devices I tried. But, They did not seem to support ALL the RS232 lines. The USB to RS232 converter using the FT8U232AM and a Maxim-IC MAX235




Ethernet Weather Station

Ethernet Weather Station

Using an add-on card to the already existing avr ethernet board we build a weather station. That is: A weather station with a build-in webserver. My original plan was to have sensors for temperature, air pressure and wind. I started a prototype and it worked very well except for the wind measurement part. I plan to improve the wind measurement hardware and add it at a later point in time.




1.5V to 5V Converter

1.5V to 5V Converter

In many cases can be very handy to be able to convert 1.5V to 5V. Then you can power microcontroller or LED from a single AA or AAA battery. It is simple to do this as there are special IC’s as MAXIM MAX1674 or MAX7176. This is step-up DC-DC converter that can convert voltages from 0.7V to any in range from 2V to 5.5V. MAX1676 have already preset pins for 3.3V and 5V, that makes easer integration in 3.3 and 5V circuits. IC can dissipate up to 444mW. Bellow is a circuit that converts 1.5V to 5V.




USB to RS232 Dongle
Posted on Friday, April 16, 2010   •   Category: USB Circuts

USB to RS232 Dongle

With serial and parallel ports being phased out on new computers, hardware designers and hobbyists have no choice but to convert the USB port back to RS232 serial. FTDI have a very nice chip that does just that, the FT232AM. This chip converts USB to a standard high-speed serial port. The bonus with FTDI is the drivers are already written for you. All you have to do is design the hardware and download the serial USB drivers from FTDI's web site.
