MiST Mod

[Gryzor]

Ohh AND they have colors, too!

[Bryce]

You won't see the colours when the original button is glued on top

Bryce.

[Gryzor]

But.. I like colours

[Bryce]

Good, grey is a colour.

Bryce.

[Gryzor]

Ahhh yeah, though technically it's a mix of black and white, can you add two non-colours to get a colour?

[Bryce]

I'm sure MacDeath can create an overly complicated pallette to explain just how many greys you can get from two "non-colours"

Bryce.

[Gryzor]

Mmm looking forward to multiple system palettes!

[Bryce]

So after much planning, I finally bit the bullet and cut the button in three:

[attach=2]

Next I had to file down the buttons to get the caps to fit:

[attach=3]

Without the outer housing they flap about all over the place.

[attach=4]

With the outer housing they still don't look great. I'll need to do some fine tuning and maybe add some more guiding to get them to line up nicely, but generally I think my plan is going to work.

Bryce.

[Gryzor]

Well, it does look like an old man's teeth about to fall off, but on the flip side it does look promising and cutting went obviously well Maybe a bit of filing? Can't wait to see how you're going to add more guiding...

[Bryce]

Filing won't help, I need to close the gap around the buttons where they leave the casing, that should line them up nicely. The caps are fixed securely, but the buttons have some play, so the current gap allows them to waggle a little at the moment.

Bryce.

[Gryzor]

Ah I see. I mentioned filing not to stabilise them, but for the looks of it - smooth a couple of rough edges, but yeah, if they come together nicely it may not be necessary...

[Bryce]

Just doing the last few edits and additions to the MiST and started testing....

The shitty SD Card extension is causing all sorts of stability problems. Sometimes it boots, sometimes it doesn't. When it does run it suddenly decides the card was removed although it wasn't. Looks like extending the SD slot isn't an option, I think I'm going to have to remove it and put the SD card back inside

Bryce.

[Gryzor]

Wait-what? How?

I mean, of course if the extension is not an option something has to give, but the slot needs to be accessible... Am I missing something?

[Bryce]

Wait-what? How?

I mean, of course if the extension is not an option something has to give, but the slot needs to be accessible... Am I missing something?

Yeah, I'm not sure. I'll try screening the cable, but I'm not optomistic. I really don't want to add a slot at the side for it

Bryce.

[Gryzor]

Hmm, yeah, definitely a side slot won't be nearly as nice. What does screening mean? Maybe try a different extender brand?

[Bryce]

The extenders all seem to come from the same source. They all use FPC (Flat Protruded Cable). This one was actually 3 times longer when I bought it. I didn't stand a chance of working. At 11cm it's hit and miss. I could try wrapping the FPC in metal screen, or even using twisted pairs for certain signals. The MiST board seems to be just too noisy to route this across it.

Bryce.

[Gryzor]

Ah,I see what you mean, and the source of trouble. I guess the board doesn't have FCC approval then

[Bryce]

I guess the board doesn't have FCC approval then

I'm still going to be laughing about that one on Monday!

Bryce.

[Gryzor]

Yeah, you're right, of course it does have approval, it's just that it's only valid for the complete, encased unit, not the monster truck you're building.

[Bryce]

You need more than just a metal box to get FCC approval. For a start you need wads of money, which most hobbiest designs won't have a budget for.

Bryce.

[Gryzor]

I don't think that box can fit many 'wads of money' though...

[Gryzor]

Ps "most"?

[Bryce]

Yes, most. It's rare, but there are true hobby projects that have ended up as full blown products.

Bryce.

[Gryzor]

Ah, ok, that's no hobby by then, then.

[Bryce]

Ok. after sleeping over it, I've decided to remove the extension cable and make my own extension with twisted wires. I'll let you know if it works.

Bryce.
