| − | ===Tools===
| + | |
| − | Basic wiring tools need to be dedicated to the ECE bench. Here's a quick list: Hand tools. The bench (and the rest of the 'Space, as far as I can tell) has some decent diagonal cutters and that's about it. Here's my proposed list to get things started: Solder paste, desoldering braid, cheap desoldering iron, solder sucker, spare iron tips, no-clean liquid flux pen, solder assist tools, decent needle nose pliers, Panavise Jr, wire strippers.

| − | ===Power===
| + | |
| − | A standard PC power supply in combination with a [http://dangerousprototypes.com/2012/06/28/new-prototype-atx-breakout-board ATX Breakout Board] (abt $14 + tax/shipping from Seeed) could provide additional regulated supply voltages and it could be the starting point for an alternative implementation (more ripple filtering, higher current limits, exposing the -5V source, adding a 9V source, etc). Unfortunately, Seeed is out of stock. An alternative is to get a [http://www.sparkfun.com/products/9498 right-angle ATX connector] and [http://www.sparkfun.com/products/9558 bare breakout board] from Sparkfun (abt $7 + taxes/shipping) and mount it in an aluminum box with binding posts that [[User:Petesoper]] can donate. The Seed unit should be gotten eventually as it has current limiting fuses needed for safety. (Although shorting an ATX power supply will ordinarily cause it to fold back harmlessly, under the right circumstances enough current is available to cause a severe burn hazard)

| − | An assortment of dongles and adapters will be needed.
| + | |
| − | | + | |
| − | ===Logic Analyzer===
| + | |
| − | The [http://dangerousprototypes.com/docs/Hardware_design_overview Open Workbench Logic Sniffer] may be the perfect intersection of price point and utility for this function. One has been ordered along with probe sets for 16 channels.
| + | |
| − | | + | |
| − | ===Oscilloscope===
| + | |
| − | While a PC oscilloscope may be able to reproduce analog signals for a desirable purchase price, finding one with decent Linux compatibility may be a challenge. Splat Space supporter Forest is investigating a possible donation by Duke University.
| + | |
| − | | + | |
| − | A '''[http://www.jyetech.com/Products/LcdScope/e062KC.php JYETech kit]''' might be a good starting point for developing our own cost-effective, Linux-supported PC oscilloscope. It has an analog bandwidth of 1MHz and costs $49.
| + | |
| − | | + | |
| − | The '''[http://www.vellemanusa.com/products/view/?id=524708 Velleman PCSGU250]''' combines 2-ch 12MHz oscilloscope, baseband spectrum analyser, transient recorder, function generator and bode plotter, and would cost our club $179.00 and would sell to the public for $350.00. Not bad, but not as
| + | |
| − | good a value as we could get, and its proprietary software won't run on Linux or OS X.
| + | |
| − | | + | |
| − | Potentially the best value is the '''[http://www.bitscope.com/product/BS10/ BitScope Pocket Analyzer]''', which combines 100MHz oscilloscope, 40 MSps 8-ch logic analyzer, serial logic and protocol analyzer (SPI, CAN, I2C, UART, and analog), RF and baseband spectrum analyser, arbitary waveform and protocol patterns function generator, and multichannel chart recorder. Its (proprietary?) software works on Windows, desktop Linux distributions, OS X and Android. The device costs $295.
| + | |
| − | | + | |
| − | The '''[http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,842,1018&Prod=ANALOG-DISCOVERY Digalent Analog Discovery]''' kit combines dual 5 MHz, 50 MSPS, analog inputs, dual 5 MHz, 125 MSPS analog outputs, 2 fixed +/- 4.5 V power supplies and 16 signal 100 MSPS digital I/O. The (proprietary?) software is currently available for Windows with Linux and OS X support "soon" as of 2012-03-24. The price is $149 with academic pricing or $249 otherwise (and only $99 if we can buy one used from a student who qualified for their lowest pricing tier).

| − | ===Function Generator===
| + | |
| − | Some PC oscilloscopes also have function generation capabilities, but again, Linux support may be difficult.
| + | |
| − | | + | |
| − | ===Frequency Counter===
| + | |
| − | A frequency counter is especially useful when rebuilding old radios (ie. 1950's or earlier), old military equipment, microwave and radar communication devices, broadcast TV and Radio "Marty" equipment, ham radio equipment, and so on. For example, even a digital storage oscilloscope cannot give you the frequency of a signal as accurate as a frequency counter through several stages of pentodes and triodes in an old TV. Some military gear, if not tuned to 1% or better accuracy (an O-scope is good for about a 5% accuracy), you will not get a SSB signal and thus, not get the signal of interest--such as the older marine positioning system.
