The Crossbow Classic PI

[alcapone]

Can you tell me what effect changing irf740 to order840 has on the crossbow. Thanks.

yes thats the one.
yes i did get a manual with it. i have not used a PI before. i have always wanted one. i have recently been trying to put a Sniffer XR-71 DELTA PULSE together as a project, but i am not having much luck with it.

Is this the Crossbow PI that was sold recently on UK eBay?

If so, it uses a PCB that was supplied by Sven, and I believe it has been slightly modified. As far as I could tell from the eBay photos, the battery check circuit and the internal battery charger have been removed. The NiMH battery pack has been replaced by a Li-ion pack, and a suitable external charger. Also, the MOSFET has been changed from an IRF740 to an IRF840, and the electronics are housed in a different enclosure. There may be other changes, but these are not immediately evident from the photos.

I can send you an original User Manual by email if you wish.
