- The Hardware Book
The Hardware Book contains misc technical information about computers and other electronic devices. You'll find the pin out to most common (and uncommon) connectors available, as well as info about how to build cables.

A simple little Ohm's Law calculator - input two of the known values (power, voltage, current, resistance) and get the last two calculated. Might be handy for quick calculations - has been for me, anyway.

There are two ways to connect a pair of speakers together. You can have series or parallel. Easy enough?
What happens when you hang that twin speaker extension cab off your 1 x 12"?? Hmm... gets a bit more complicated. I've put together an Excel 5 spreadsheet which caters for many different wiring combinations of 2, 3, and 4 speakers.
Given the power output of the amp, it will work out the total impedance that the amp "sees", and will work out the individual power within each speaker. It has pictures of the different configurations within the spreadsheet, so you can use these as a reference for wiring the speakers up too....

The Tone Stack calculator is designed to help you check out the design and response curves of a variety of tone stacks used in popular guitar amplifiers. It is intended to be of interest to amplifier technicians, amp modifiers, hobbyists and students.
Key features
Tone stack types: Fender modern, Vox, Marshall, James (passive predecessor to Baxandall), Fender E series, Steve Bench tone stack, and now the Big Muff tone stack used in FX units. Simply click on the appropriate tab to bring up a different schematic.
Components: Values can be altered simply by double-clicking on the component. With potentiometers, the taper can also be altered. The generator source impedance can be altered to give realistic simulation results for both cathode followers and common cathode drivers.
Bass/Mid/Treble: Slide the controls along and see the changes to the tone stack response in real time.
Snapshots: Freeze any trace so it can be overlaid by other traces. Up to a maximum of 12 traces can be frozen in this way. Can sweep the controls to show the range.
File Open/Save: Keep your favourite configurations on disk with this new facility.
Printing: Send the graphical results to your printer for a hard copy.
Other features: Online context sensitive help, variable plot resolutions supported to optimise performance.

This is a small program to find transistor data. Not everything is listed (1442 different devices). Download a copy, place it into the directory of choice and run the program, which is a self extracting archive. There are two extracted files - ESP-TRAN.EXE and BIPOLAR.TXT, being the executable and database respectively. ESP-SEMI.EXE may be deleted after extraction unless you want to give a copy to someone else. New stuff can be added as you find the data. If you add a lot of stuff, feel free to e-mail me a copy of the new database (compressed, please!), and I will add it to the database file.
For users who eschew Windows, the text file is still useful, as it can be read with any text editor or even a spreadsheet (TAB delimited format). Be careful with spreadsheets, as they like to try to convert some data into dates (really useful - not!).

Selguide is a software tool designed to guide the user in selecting our Operational Amplifier, Buffer and Comparator products by enabling the user to enter in a few key parameters and have a list of devices meeting those parameters returned to them.
Included in the results is a summary table of key device parameters and pricing information, as well as a link back to view our Web site product folders for the chosen devices (You must have a Web browser and a live Internet connection to view the web pages).
Installation of the Selguide software is simple and painless. Selguide does not add to or modify your system files at all and is completely self contained within one folder. Selguide fits nicely in a corner of your Desktop or Laptop PC for easy future reference.
