No new backplane is needed. It works. If the anybody want to listen to this story, i'll write about it. __________________ O'Razoff

Filling the mold seems tom make me nuts: First attempt was to just press the epoxy inside the mold with syringe 1th try: only one string carbon fibre an unreinforced epoxy: too much bubbles and epoxy only w/o fibre reinforcement is to weak.(pic1) 2nd try: a pice of carbonfibre and epoxy with short fibreglas (ca. 0.2mm long): even more bubbles/lugs (pic2) 3rd try: one string carbon fibre and epoxy with short carbon fibres (3-5mm long):Can't even press the expoy inside the mold, so I tryed to do it with vacuum. This 'sucked' the epoxy inside the mold, and left the carbonfibre inside the syringe and then 'sucked' air through the dry fibres inside the mold (pic3). Additionally all results are not as stiff as the prototype (which was made out of several layers of fibreglas-tissue). So next try is to place one carbon fibre-roving (as in all trys before) an several layers of tissue inside the mold, press it together and then use vacuum ti 'suck' the epoxy inside the mold and tissue. I hope I can minimize the grinding work after that by figuring out the best shape for the tissue pieces I use for that. mc -nevergiveup- lien __________________ My battery supplier: http://www.lipopower.de Last edited by mclien : 03-07-2007 at 01:19 AM.

Good thing in this situation is, that with the mold ready it's faster to make trys with it (only one day time for harden. so far a movie quote "I'll be back" ... __________________ My battery supplier: http://www.lipopower.de

Though I think Mclien's mod will allow for longer life due to the higher mAh. Have you run any benchmarks on how long the battery lasts with that mod?

I have'nt run any benchmarks, but last time I'v charged the battery was Sunday, 16:00 Msk. Now the battery's charge is 54%. 15-30 minutes per day reading, notes, time. __________________ O'Razoff

And I have to build a new (upper) half of the mold. It shouldn't be with a layer of silicone/polysiloxane for 2 reasons: you won't get a smooth surface, because of the flexibility and the metal parts,which are placed in the silicone bend inside when there is a pull in the carbonfibere. So I got a good filling of the mold (no bubbles of air inside the item) bit the holes for the screws lost their position (pic2). So I need some extra time for the next version of the mold. so long __________________ My battery supplier: http://www.lipopower.de

That's pretty cool

Definitely better then my current "30 mins of use if I'm lucky"

How much use per day?
Watch face on/off?

And :
my new mold is working. As soon as my battery supplier has got the batteries in stock again I'll start shipping the molds.

This Version is with glassfibre and a single carbonfibre, which sourrounds the screw holes (the only way to make these things stable enough). And I used the clear epoxy to see, if erverything works well. Most likely I will just use black colour paste to make it black (if you like it without colour, to see the technology I do it that way of course). OK perhabs I'll try some special glassfibre which is aliminium clad (but perhaps this tissue is to rigid to fit the mold). I'll post, when the modding kids are ready. __________________ My battery supplier: http://www.lipopower.de Last edited by mclien : 03-17-2007 at 01:55 PM.
