• 555 Timer This program allows you to calculate Resistor and Capacitor values for both Astable and Monostable modes. Please note that this program was written using Visual Basic 4.0 Therefore it requires the Visual Basic 4.0 Runtimes.
• Schematic Symbol Reference 1.0 This is an offline version of the Schematic Symbol Reference. It contains all the same info, but is a standalone program that requires no Internet connection to run.
• 555 timer designer This freeware program is very useful for designing 555/556 timer applications. Enter frequency (or pulse length) and duty cycle, then click on Calculate. Timer capacitor C1 values can then be increased or decreased, with resistor values changing accordingly. Features: four operation modes (3 astable plus monostable) 16 application examples timer/component specifications
• Resistor Color Coder This freeware resistor color code program is very useful for determining color codes or values for 4 and 5 band resistors. To select the mode, click on the 4 or 5 band resistor icon in the upper right The lefthand 3 or 4 bands determine resistor value, the righthand band resistor tolerance.
• IC-Databook In this IC-Databook Software you will find pin assignments, connection layouts, function tables and the most important specifications available for the 40x.. and the 74x.. IC series. In the actual software version are already the data of more than 230 different IC’s. You can easily add additionally IC’s add or edit existing IC’s and exchange them with other users.
• ESP Transistor Data 1.1 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!).
• Speaker impedance calculator 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 complicatedg diagram and pin list for over 4,300 vacuum tubes. The example shown (and following examples) are for the 6K6-GT more at: http://www.duncanamps.com/tdslpe/index.html

• Oscilloscope for Windows v. 2.51 Oscilloscope for Windows is a Windows application that converts your PC into a powerful dual-trace oscilloscope. Oscilloscope uses your PC’s sound card as an Analog-to-Digital Converter (ADC) to digitize any input waveform (speech, music, electric signal, etc.) and then presents it on the monitor in real time, allowing the user to control the display in the same way as on a conventional “standalone” scope, for example change gain, timebase or plot Lissajous patterns. Main features · Any sound card can be used · Single trace, dual trace and XY modes · Spectrum analyzer (realtime, built-in) · 20 kHz bandwidth · Triggering · Point-and-click meter function · Storage mode · Data export to Windows clipboard or disk file
• BIP Electronics Lab Oscilloscope – 3.0 The BIP Oscilloscope uses the sound card’s input to measure signals. This means that the quality of the scope depends on the quality of your sound card. The scope has the following properties: Sampling frequency: The scope automatically uses the highest sample frequency available at the input that you select (usually maximal 44 kHz) Accuracy: The scope uses 8-bit samples to read the input signal. Input impedance: The same as the input impedance of your sound card.
• Spectrogram version 5.0 Spectrogram version 5.0 is a freeware dual channel audio spectrum analyzer for Windows 95/98/NT which can provide either a scrolling time-frequency display or a spectrum analyzer scope display in real time for any sound source connected to your sound card. (License: Free) 1. Analysis and identification of biological sounds 2. Analysis and identification of human speech 3. Analysis of musical performances 4. Tuning of musical instruments 5. Evaluation and calibration of home audio systems 6. Ham Radio audio reception and tuning 7. Analysis of radio interference including atmospheric electromagnetic effects
• Sound frequency analyzer Whistle a melody and watch this program graph the pitch in real time. The Frequency Analyzer technically speaking performs a Fast Fourier Transform of the sound (you need a sound card and a microphone to use this program). What it means is that it analyzes your voice and splits it into its component frequencies. Watch patterns of speech, the harmonics of vowels and the noise of sibilants. The size of the program is only 64k! (zipped 32k) Can you believe that?! There are web pages that make you download more than that just to be able to look at them.look at them.
• Sine Wave Generator The BIP Sine Wave Generator uses the sound card’s output as sine wave output. A built in sweep algorithm is used by audio hackers to measure frequency repsonses of their amplifiers.The generator has the following properties: Sampling frequency: The oscillator automatically uses the highest sample frequency available at the output that you select (usually maximal 44 kHz but people with 22 kHz max. also use the generator without any problems). Ounput impedance: The same as the output impedance of your sound card. Normally the output of a sound card is very low (which is good) in order to be able to connect a speaker (which is not needed for this application). Accuracy: The generator uses 8-bit samples to generate the sine wave signal. The sine wave is created using a secret algorithm which makes use of special floating point instructions of your microprocessor.
• SweepGen SweepGen turns a PC into an Audio Oscillator and Sweep Generator which can be used for testing audio or educational purposes. In conjunction with audio test instruments, you can make frequency response plots. SweepGen uses the sound card in your PC to produce sinewaves that are mathematically correct almost to CD quality, indeed it’s more likely that the quality of your PC sound card will be the limiting factor rather than the code in SweepGen.
• Test Tone Generator The Test Tone Generator (TTG) turns the PC into a function generator for testing or demonstration, sound tuning, education, for sound effects and other purposes. It can produce constant or ‘swept’ test signals in real time. You can also save the signal as a .WAV file, e.g. to burn a test tone CD. You can also run scripts of test tones and save 4 memory presets of fixed or sweep test signals and supports multiple sound cards.
• Frequency Counter This is a frequency Counter that uses your sound card.
• SB Oscillograph 1.0 It is real digital oscillograph. Your sound cart can give 16 digital bits, and has two independent channel. It’s great, it gives about 150 microvolt precision level. Frequence limit isn’t hight, no more then 44100 Hz, but in many case it is enough.
• Super Simple Serial Terminal You can use this program to debug and monitor your serial port.
• SuperTerm V2.01 This Program is a very simple to use, but POWERFUL serial debugging utility. It has a scripting engine, allowing you to send programmable sequences of bytes to the serial port at the click of a button. The program also features a HEX window as well as control and monitoring of the RTS/DTR, CTS/DSR signals.

• ImageMagick ImageMagickTM 5.5.7 is a robust collection of tools and libraries offered under a usage license to read, write, and manipulate an image in many image formats (over 89 major formats) including popular formats like TIFF, JPEG, PNG, PDF, PhotoCD, and GIF. With ImageMagick you can create images dynamically, making it suitable for Web applications. You can also resize, rotate, sharpen, color reduce, or add special effects to an image or image sequence and save your completed work in the same or differing image format. Image processing operations are available from the command line, or from the C, C++, Perl, Java, PHP, Python, or Ruby programming languages. A high-quality 2D renderer is included, which provides a subset of SVG capabilities. ImageMagick’s focus is on performance, minimizing bugs, and providing stable APIs and ABIs.
