- I have a project that involves testing solar cells for my university's
- (University of Texas at Austin) entry into Sunrayce '93. It involves testing
- of solar cells for their power output over a wide V-I range from 0 volts
- at max current to 0 amps at max voltage, with the ultimate objective of finding
- the cells' fill factors. I need to do this with a computer to reliably and
- quickly record the V-I performance of the cells and with a budget for around
- $300 for hardware and software. The arrangement should be for eigher
- a Mac+ or an Apple II family member (the two types of computers I'll probably
- ever have on hand for the duration of the project), but I'll accept ideas
- involving any type of computer.
-
- Some of you might recognize that the same request was made earlier
- this month; I have gotten e-mail replies, but my system mailbox has
- been giving me hell and I lost all the solar cell-related e-mail in the
- process (Looks I'll be doing alot more screen dumps to microcomputer
- whenever I logon via modem from here on). In particular, I need to
- get in touch with the persons who:
-
- Suggested two DVM w/serial ports
- A Mac-usable data acquisition module sold by a California firm
- and,
- Has some ideas involving an electronic load
-
- I'll happily accept others tho...
-
- Sorry to bother you again,
