Looks like the seller wised up to this pcb being worth more, original listings "sold out" but he has another listing for the same board for 3x as much. and it now says "Gemini-2 losmandy telescope

For sure! i have some in my cart on amazon, i figured id put a little tiny heatsinks on the driver chip and the main processor with some thermal epoxy, and conformal coat the whole thing. poor pcb was

Dear Sonny E., Please send me the $600 difference so I can return this board and buy a backup circuit board directly from Losmandy. -- Chip Louie Chief Daydreamer Imagination Hardware Astrospheric -

I'm in doubt of your conspiracy theory on these boards.? It is pretty difficult to copy a multi-layer board and reproduce all of the details of a board like this so exactly right down to the

You may be right. But since you and I, and probably everyone else here don't know for sure the provenance of these boards, I'd be cautious about making strong claims. The boards can be cosmetic or

Listen to Kevin O¡¯Leary and you will know exactly what is happening. Dollars to donuts the board is made in China. They steal US Intellectual Property with impunity because no American company can

IDK if this is common in USA manufactured parts like this from a military grade contractor but this should be traceable by the contract.? This is a custom job not some normally stocked production

Ah I see. It's the salty air. There are spray-on conformal coatings for pcboards that can be applied. Techspray is one I'm aware of, which is an acrylic coating. If you get a new board, it may be

Right. That's why I'm questioning the source, as these may be illegal clones or some rejects from a legitimate run of PCBs with some "unknown" defects.

There are stories of manufacturers just ¡°running some extra¡± of a part they got paid to make for someone. So imagine you get asked to make 100 units, and instead you make 200 for some reason ,

Those were the days.? When I used to do component level repairs and hot rod computer boards one of my tricks was using a tiny pin vice to drill partial on a trace through the mask exposing the trace

It is a curious thing.? Normally this sort of thing is protected by contract but here we are.? I just hope it works and I get a backup board. -- Chip Louie Chief Daydreamer Imagination Hardware

I'd be curious to find out the source of these PCBs, as well. These look like the real deal, but I wonder how some third party came into possession of brand new, unconfigured PCBs.

I have tried doing the repair, the issue was condensation build up inside the metal casing lead to a pretty bad series of shorts that burnt some traces. I tried repairing the traces with ultra thin

You can easily replace the USB port if it has physically broke. If you don't have the soldering tools to do it yourself, any semi-competent electronic/phone/ipad repair shop should be able to bust

I'm not sure I understand what you are saying.? The board will either work or it won't - if you have put the right files in the right place on the micro SD card, programed the bootloader code out to

I also ordered one and the bootloader writer, and motor fw writer. My PCB works, but I broke the USB port so I¡¯ve been looking for a replacement for a while that isn¡¯t $700. I¡¯m excited to play

I have bought this card and programmed the ARM processor and the pics with available files. To my understandingit works, the hand controller shows the right software versions when connected.
