Who will be first??? Working MiniMIG v1.1

[amazing]

i ordered 1 board too...for 14,99 i can mess up a bit

Have you successfully soldered the FPGA this way?

[bon]

I got my self a PCB too. It would be VERY helpful if someone could give us a complete list with all parts and where we can buy them...

[tonyyeb]

Has anyone got a working one yet?!

[whiteb]

I am within a week of this, Boards arriving along with the parts.

The biggest stubmling block right now, will be the lack of ability to understand the FPGA core compiling software (ISE), and PIC firmware compile.

Without those, nobody can go anywhere.

One stays with me in Australia, two will end up in the USA, with an ultimate destination of some obscure Chinese factory to be dissected again for *MASS* production.

I will post the FPGA compiled core that was created from Xilinx ISE later today on rapid share.

Here is hoping it can be done cost effectively. How much has it cost you so far if you don't mind me asking?

[whiteb]

Great, thanks for that jk

Just the Pic firmware now.  Needs compiling in a 18LF252 compatible C compiler.

ROFL, Dont ask.

In an ideal world, I would have just done 100 and reaped the discounts, but I saw what happened with Xenepp, and with definate people with a YES, and Reserve, he was still left with boards he couldn't ship.

All up, so far its worked out to 98 GBP, 208 USD, or 230 AUD. (EACH).

On top of that, will be the cost of an MMC card, and a powerpack.

The biggest hit, was $70USD postage from Digikey. (FPGA, Ram etc).

Made a MASSIVE error on Ebay with the boards, Instead of ordering three boards, I had ordered 3 lots of three, but that was sorted out quicky.

[tonyyeb]

£98!!! Bargain! Mass produced should be even cheaper!

[jkonstan]

Here is the rapid share link to the complete ISE project for MiniMIG1 Spartan3 FPGA including the Compiled FPGA code and sources. The file minimig1.bit is the binary image to the Spartan3 FPGA. This code is under GPL etc ......

Also, I am still assembling my MiniMIG1; thus, I have not been able to test the binary FPGA code yet.

So do you have a copy of that parts invoice from digikey? I'm thinking I could just place the same order with my account.

Thanks JK, now I just need that PCB to arrive and place my order at digikey.

Mass production costs still require pruchase of the MC68000 and FPGA chip, those prices will be hard to adjust and I've been informed that there are no low cost Chinese replacement parts for these chips.

Advantage of getting this done is China is that most every other part can be made from Chinese suppliers for lower cost. You still have to pay for packaging, power supply, MMC card, Shipping & distribution.

First costs for a case work is $5 per cost per unit in numbers of 1000. These numners are FIRST COST and do not reflect markups from the agent, and shipping and development costs. Someone would have to design and output a case design and that is even more cash on top of the tooling costs. Initial runs would be more expensive to help cover tooling cost.

Also... tooling a case ads a few months to develpment time (AT LEAST 90 DAYS from turnover of finished model to first shot out of the mold) and initial production units)

Yes I do.

You could probably get a large number of the items from Digikey, but it was easier (And cheaper for me) to get SOME items from Farnell in AU$.

If there was any, you would probably find some pretty awful side effects in the opcode no doubt.
