Talking Electronics
A variety of kits are available for purchase; however, complete schematics and PCB designs are available as well if you want to source the parts yourself. |
Capacitor part codes
Good run-down on how to read capacitor codes. |
Bowden's Hobby Circuits
Schematics for many different circuits. |
TI Logic Data Book
A pdf of many different chips in many different logic families, 700 pages in all. A great reference. |
ALLDATASHEET
Datasheets for many different chips. |
About the differences between the TTL families
Some good advice regarding TTL and CMOS interfacing. |
The basics of integrated circuits
Good information on the difference between TTL, AC, ACT, HC, and HCT families. |
Play-Hookey Website
Sections on computers, digital logic, DC electronic theory, HTML, op amps, analog circuits, and optics. |
DISCRETE WIRING JUMPER WIRES
Check out this beautiful document on the proper way to do point-to-point wiring for minor circuit modifications to existing printed circuit boards. |
SIMPLE EPROM PROGRAMMER
|
NIXIE TUBE DISPLAYS
The tube that was made popular by the Burroughs "destroy all rational thought" Corporation. |
RESISTOR COLOR CODE CALCULATOR
|
Epanorama
Tomi Engdahl's Electronics information web site. |
HVWTech
Wide selection of robotics supplies. |
LM4752
TO-220 single component stereo amplifier. Throw in some resistors and caps, and you have a thermal protected amp. |
The Guru's Lair
Don Lancaster's site. Go there and buy the TTL and CMOS cookbooks. I won't even try and take the Amazon link on that one. :) Tip o' the hat to Don for writing my most-used book, the TTL Cookbook. |
Expresspcb
PCB house with free design software. |
JDR Microdevices
Most everything you need to build a homebrew computer, you can get from JDR. |
Jameco
Quite a few parts. Good homebrew supplies. |
Mouser Electronics
They have many more connectors, bulbs, and discrete components than JDR. |
Micro Logic Micro Charts
Do any of you remember these? They are plastic charts with summary information and diagrams. I have one for the Z80 and 8048 that I use that are from the early 80s. You can still buy the Z80 chart, as well as the 8048! |
PCB
Printed Circuit Board program for Linux. |
Top Bulb
I bought some bulbs for my EPROM eraser at this place for $7.50 each. My eraser uses G4T5 bulbs. You have to take the bulb out and look at the part number. Don't rely on what the eraser manufacturer tells you the part number is. |
Lessons In Electric Circuits
A free series of textbooks on the subjects of electricity and electronics. |
