PCB designs sent

Three receiver layouts and two remote control layouts will be produced (short run) and the best combination chosen and compared with all the manual antenna tweaking we've been doing so far. The weekend was spent studying antenna theory in preparation for this.

Also the motors have successfully been bonded to the metallic harness but battery welders did not do the job so we had to use a laser welder. Jason's still testing whether the motors still work after this process and if they do we'll try to overmold them. This time no glue will have to be added, so there will be no chemical interference with silicone curing, also the quantity of material inside the mold will be exactly the same each time.

Update: the laser welded motors work. The mold is being enlarged slightly (0.5mm) so that the metallic piece can fit. When this is done we'll overmold and report results!

The rubber molded over the motor will come in contact with the skin potentially for extended periods. Are there checks in place to make sure the rubber is safe? What is the rubber's composition?

Pure silicone

Build quality has thus far been very high (probably higher than what most chinese places are used to)...so I am pretty confident that success is assured, and I'll do my best to make you successful ;)

Thanks, sorry no time to guide manual development right now but do look back at all the blog entries there are lots of questions that have been asked. Quality is very important for us, right now we're on the phone with antenna manufacturers, test labs, RF circuitry designers to extend range and bring you the best possible product even if it means additional manufacturing steps and additional testing to be in line with all the regulatory bodies...

I'm confused. In one statement you refer to the product used in the over-mold as rubber and in an answer to a post it's now pure silicone. Silicone is not the same as rubber. They two different and distinct products.

Rubber is a generic term, including many specific substances, like EPDM, silicone rubber, etc - that's our understanding we're no experts. The material used is silicone, for all our rubber parts.
