Controlling Stepper Motor with a Parallel Port
Posted on Tuesday, April 8, 2008   •   Category: Stepper Motors


This is an easy to build stepper motor driver that will allow you to precisely control a unipolar stepper motor through your computer's parallel port. With a stepper motor you can build a lot of interesting gadgets such as robots, elevator, PCB drilling mill, camera panning system, automatic fish feeder, etc. If you have never worked with stepper motors before you will surely have a lot of fun with this project.


TDA7000 FM Receiver / TV Tuner / Aircraft Receiver
Posted on Tuesday, April 8, 2008   •   Category: FM Radio / Receivers


This simple one chip FM receiver / TV tuner will allow you to receive frequencies from 70 up to 120MHz. With this small receiver it is possible to pickup TV stations, entire 88 - 108MHz FM band, aircraft conversation and many other private transmissions. It is a perfect companion to any FM Transmitter especially if FM band in your area is very crowded. TDA7000 receiver offers very good sensitivity therefore it will even allow you to pickup weaker signals that cannot be heard on conventional FM receivers.


DIY Bench Power Supply
Posted on Tuesday, April 8, 2008   •   Category: Power Supplies


This is a bench power supply with regulated DC outputs -12V, -15V, +5V, +12V, +15V, and variable and one +35VDC unregulated output. I based this bench supply almost exclusively upon Andrew Kilpatrick's design. I did add a few things, but it's essentially the same and I am not writing here to claim any shred of originality. I spent somewhere around 80$ US on the project (including the GIANT transformer), which isn't bad compared with commercial supplies boasting similar features. Please note that I DID find a few minor errors in Kilpatrick's schematic, which have been fixed here. For details, read Kilpatrick's original page.


8W PLL Stereo FM Transmitter with LCD
Posted on Tuesday, April 8, 2008   •   Category: FM Transmitters


Very stable FM transmitter based on TSA5511 synthesizer. Frequency is performed with three buttons through PIC16F84 microcontroller. Frequency is displayed on 161 LCD.


Designing PCB with Eagle CAD
Posted on Tuesday, April 8, 2008   •   Category: PCB


To design my circuit boards, I use the freeware version of the Eagle Layout Editor by CadSoft Computer GmbH. The software is located in the download area of their site. I give an introduction to Eagle under the category Eagle CAD. For convenience, here is a list of the posts: * Eagle 1: Description * Eagle 2: Libraries * Eagle 3: Setup * Eagle 4: Schematics * Eagle 5: Components * Ground Pour * Setting All Drill Sizes * Setting All Pad Sizes
