If you haven't already given the game away, you might get a couple of 'samples' out of them if you can convince them you're in the market for several thousand ;-) Colin f ________________________________________________ Message sent using UebiMiau 2.7.2

colin, the BOM states that all resistors should be 0.6W, but those seem to be impossible to find over here. is that a typo? should it be .5? i've even searched for "2/3 resistor" and have found nothing helpful... thanks, fred. bleep. out. --- http://leichenfeld.iuma.com http://thirdwavecollective.com

It's not critical - even 0.25w should be fine. The important thing is to get them to fit 0.3" hole spacing. > in the instructions on the webpage, it seems that you have the two pot > boards and the led and switch boards going into the same > IDC16 header on > the main board... the secret being a connector in the middle > of the cable. > could you give us the details of this connector and how to hook it up? Eh, no - the two pot boards connect to the POTS connector on the main board, and the three LED & switch boards connect to the LED/SW connector on the main board. The Pot bus cable is shown here: http://www.colinfraser.com/p3/images/pot-board-wiring.jpg And LED/Switch bus shown here: http://www.colinfraser.com/p3/images/sw-LCD-wiring.jpg Both shown on this page: http://www.colinfraser.com/p3/p3-build-final.htm There are other photos where the routing of the cables is less obvious. I'll need to write some instructions for assembling the cables - I have to measure the spacing of the connectors up each time I put a set together myself, so it would make sense to write them down. Cheers, Colin f

Ah, I get you. The mysterious connector is justthe same 16 pin IDC connector as used at either end of the cable. The ribbon passes straight through them, so they can be squished on anywhere along the cable. Same as the two hard drive connectors on a normal IDE cable. > i can't find the exact heatsink that you specify in the BOM... can you > give us a little more information about it so us colonists can find a > decent substitute? There's a question ;-) The heatsink used will need to dissipate enough heat to stop it over-heating. How much heat is produced by the regulator will depend on the power supply voltage. The part I use has a rating of 20 degrees C per watt. Probably any clip on TO220 heat sink will do as well, if it has similar dimensions. > (US BOM 90% done!!!) Cool. Cheers, Colin f

hi colin... i can't find the exact heatsink that you specify in the BOM... can you give us a little more information about it so us colonists can find a decent substitute? thanks! (US BOM 90% done!!!) bleep. out. --- http://leichenfeld.iuma.com http://thirdwavecollective.com

Hello-- >(US BOM 90% done!!!) Oh wow! The embarrassing news from me is that I've got this big pile of P3 circuit boards and haven't gotten around to picking up anything for them yet. :-( Er, so can I humbly ask if you'll let us other, slower, US builders in on the US BOM at some point? Please? :-) Frank

Please? :-) i'll post it to the yahoo files section when it's done. currently, i'm all done except for the resistors. there are two caveats, however... i'm not sure the knobs i selected will work with the pots (they're not exactly the same as colin uses, but electrically they're the same), and also there is currently nowhere in the US that stocks 18MHz crystals... maybe we'll have to bug colin about those... :) or maybe i could order a bunch from the UK and ship them to all of you. probably cheaper that way. bleep. out. --- http://leichenfeld.iuma.com http://thirdwavecollective.com

Please? :-) I'm actually in the same boat myself. I always buy PCBs when I see them because they're typically a only made for a short run, then they're unavailable.... so I have this nice box full of PCBs that I slowly work at when I have the time. But I'm very interested in seeing the US version of the BOM!!!
