| xani:
well, ethernet use isolating transformer, just get a good one ;] |
| Curtisbeef:
For the USB data logging could it just be Opto-isolated serial lines going to a USB powered and Isolated from the rest of the board FTDI Serial Chip. Is that enough? |
| charliex:
just put RS232 out on it, after that its trivial to add on Wifi or Bluetooth. |

--- Quote from: badSCR on January 27, 2010, 10:55:40 pm ---*Serial IR ; slower speed, but the SD-Card could be used as a buffer. *An SD-Card or usb flash drive is a must for data logging. (for high speed data logging maybe 1~2Gb RAM) *Auto Ranging? *3~5 channel Volt meter/logic And Dual channel Amp meter. *Would like the ability for 10~20 DC amps continuous. *Ability to measure Resistance, Diodes, Inductors, and Capacitors. *maybe a Transistor tester. *micro volts/amps or pico volts/amps *maximum 600 Volts to 1Kv ? *phase angle (for three phase power) ? *able to use Fluke Clamp-on Current Probes (for three phase power) ? *low frequency Oscope ability (less then 200Khz) ? *A Wall-adapter for a PSU. *Able to use a Lithium-Ion battery pack from a cordless tool (non-charging). If your some where and the battery dies then you could use the one from a power tool. *D cells or the Big 6volt battery, both are easy to find. *In Resistance mode it could tell you the color code and if it is within tolerance. *Maybe a Composite video output. --- End quote --- Add an adjustable constant current output for testing LEDs.

| Thermal Runaway:
Of the features already mentioned, I have experience with the following: * LCD Interfacing via serial and parallel methods, character and graphic * SD Card interfacing for data storage and retrieval (currently working on a project that uses this) * Infra-Red communications * General Microcontroller firmware design * General electronic circuit design However, I am unlikely to be available to contribute to fun stuff like this until the academic year has ended (around about May/June). I'll follow this thread with interest until then, and see how it's progressing in a few months time. If there are still tasks I can help with at that time, I'll volunteer for some jobs. Brian |
