Motor trouble

Mr Tang's overmolded motors are worse than in previous trials - received 10 samples from him that are really poorly shaped, with pieces of rubber coming off, very ugly attachment, holes, and glue coming out. He's already wasted over 80 of our rare motors.

Immediately pinged Jason. We are ordering a mold to create small miniature metallic parts that will get spot welded onto the motors in order to stop using glue once and for all. This is our first mold to produce a metallic part. Theoretically we're already out of money but we can't go on wasting months this way, the manufacturing process needs to be repeatable!

The glue messes with silicone and screws up the curing process plus it introduces an amount of substance which has a different volume each time, molds don't like that. If Mr Tang still can't handle it we have Jason's word that we'll do this with someone else - honestly we hope he screws up again so we can get this done elsewhere, we've really had enough of trying and trying forever and spending months and wasting motors trying to get him to repeat a simple process! He's already managed to screw up with old expired rubber, with wrong hardness rubber, by changing glue when the old type was already working, and more. Sure, he's working a lot for us, but at the end of the day we have a product we need to ship and #1 is having good parts to build it.

So either way we're making the process a LOT simpler and also having a plan B in case he keeps making crappy parts. This is still good progress.

As for our other manufacturers, the LED guy won't return our money for the crappy parts he made which were already returned on his request. To make up for that we now have a GOOD battery supplier who can speak English, has supplied all safety testing documents, and isn't totally clueless like the guy we were using before. He told us very clearly the lithium polymer batteries will not create a fire even if shorted, much less explode. So we tried it (very carefully) and he was right, these batteries he sent us are totally safe even in worst case conditions.

Slowly we're forming a network of competent suppliers in all areas - sure we're having massive delays as usual, but the foundations are being built strong and sound.
