I ordered the kit the first day I could. I got it last Friday, and
put it together over the weekend. The douglas board comes with NO
assembly instrictions! These are some notes that ought to make things
easier for others:
RP1 & RP2: The both have a dot indicating an origin, the RP1 (1KX4 8
pin sipp) doesn't matter about the origin. The RP2 (10X5 6
pin sipp) the origin must be connected to 5V, so looking at
the drawing on:
(<http://lcs.www.media.mit.edu:80/groups/el/projects/handy-board/hbexp30/>)
the dot should be on the right side.
The male connectors for mating to the HB: Plug them into the HB, and
tack solder them. Only taks solder them (1 or 2 pins per
header), the HB doens't need anymore heat. The pins need to
line up, and if they are lined up before soldering they
will be more lined up after soldering. The pins are longer
than the sockets, so they won't go all the way in. This is
ok (and good).
J7 & J11: don't come with the kit. J11 probably will come with the
polaroid kit.
Good luck,

| Ummm, Hi all I'm looking for a circuit that will interface a photo transistor or a photo diode to a digital input. I tried a photocell in an analog port but it's too slow, I want to use a *visible* light pulse as an accurate trigger: ie. input (...) (26 years ago, 20-Jan-99, to lugnet.robotics.handyboard)
