Coming Soon(ish)... probably [Update - 15/06]

Time to sell off all my extra boards and parts for the UMDK, but I can't sell boards by themselves they'd need a box to keep them safe, and it's really awkward to get the UMDK in and out of the Mega Drive without a cartridge shell so it should have one of those too right?

I'll probably have 8 of them to sell, with custom coloured shells.

UPDATE - 15/06/2018

After much sanding then painting, then sanding then painting, then sanding and painting again (and again) I now have a surface finish on the shell I'm happy with and I'm ready to make a mould. But before I embark on that faff I thought I'd get on with the another slight improvement, gold plated fingers on the PCB.

Original board, with tin covered pads :(

Sanded to remove the tin (easier and safer than dissolving it), sandpaper was a bit coarse which caused a minor problem later but I'll live.
Now we're left with bare copper pads :x

Copper tape applied and conductive nickel 'ink' put between it and each pad, so that they can be plated


Nickel pads (~6 Microns) :?

And finally, Gold! (~1.5 Microns) :D

Using such coarse sandpaper (600 grit, and that's EU grit folks measured differently from US) meant there were a few deeper scratches which didn't plate very well (probably because I didn't clean it good enough). I also misplaced my titanium wire and didn't do the gold until the next day, so that didn't take quite as well as it could have (the nickel will have started to oxidise)

If I ever get more boards made, I'll add a trace to connect all of the connectors at the bottom to avoid having to link them up to be plated. Then I could simply grind away the trace.

Depending on price, I’d be interested. Starting a project and from what I’ve read that hardware would be a good upgrade to other tools I’m using.

Count me in as well as someone interested, but I have a couple of questions - if you'd be kind enough to answer I'd be very thankful!

Would the boards have all components soldered to them amushrow, or would we need to complete (+- including purchasing of all the components) the product ourselves?
Also, sorry if this has been answered elsewhere, but the software that interfaces between the debugger and the Mega Drive through the UMDK, is that available and working? If so, would it also enable step debugging with my C code developed using SGDK, or would it be assembly only? I'm using Visual Studio btw.

Thanks heaps, it's great work you guys are doing!


EDIT: Sorry, I should have read the board more thoroughly before posting questions - it looks like it should work with SGDK projects, and Visual Studio with external GDB debugging is probable, but not definite.
But getting some feedback on whether the boards come with the components, whether the boards come with the components installed, or whether the boards come bare would be great to know, alongside estimated pricing :)
Thanks all.

These would be completed kits with everything already soldered together, tested and with the UMDK firmware installed. I've already soldered together the LX9 boards, and I just need to gold plate the pins on the rest of the bridge boards before I solder the components onto them.

I'll have to work out what the final price is once everything is all done, but it's going to be £70-£100

At some point I'll also get around to making a Visual Studio plugin for the UMDK so you can launch & debug stuff from there instead of using WinDbg or something.

Please put me down as interested on your list then amushrow.

I will definitely buy one of these if offered to me. Please put me down on your list. P.S. I have a US console so I would prefer that this works with the genesis, but I'll buy it regardless....

I'm interested for sure. already have one umdk, but not gold plated so might want a second kit. At the very least I'm interested in a cartridge case!

I missed my chance the first time completed UMDK kits were available, if you're still taking names, put me down for one!
