2010-04-13 05:20:06 (4049 views) Finally all the precision work and double digit checking is starting to pay off. A bit of good news every day, and everything smoothly falling into place.
- The payment processor seems confident we can do this. We are proceeding with incorporation.
- Cable samples from two companies should arrive tomorrow - so the factory trip could happen tomorrow or the day after and we intend on leaving there with a working surprise to demo. We should also leave there with new grommets and a 100% waterproofed DL2000.

Just go on Alibaba and get samples of absolutely anything from neodymium magnets to industrial explosives sent within a couple of days. Shipping fee: a dollar or so.
  
Just fooling around massively as we're waiting for the cables to arrive... ordered some fluorescin and rhodamine B, two chemical substances that react to UV light by giving off a bright yellow or red hue. How about a red time fountain?

2010-04-12 06:37:16 (6016 views) Small incident at the labs almost turned major. Let's go with order.
Just received the special neodymium magnets we ordered last week (1 square cm x 1mm thickness). They are strong. Very strong. Too strong. This is the HIGHEST grade neodymium that can be produced. They don't sell these in shops - you have to custom make them because at this strength they are brittle - in fact some broke in half being quite thin.
We compared them with the round magnets that David (rubber strap guy) supplied. The purpose for ordering these was to check if stronger magnets can make the conductive strip method viable.

Seems like the PCB house can get the job done professionally and do the necessary import/export procedures. Spoke to two people in the company and they are both professional. We have their import/export registration documents and they're checking with the boss about how to import the components (either we order, or they order directly). We will visit their factory soon and bring PCB samples for them to copy exactly.
PAYMENT PROCESSING

2010-04-12 02:40:51 (3252 views) Sent and will arrive on Wednesday. This cable has special materials for the inside and the outside and it had to be custom created for us. It should allow the surprise to be overmolded at the right temperature and pressure for waterproofing.

2010-04-10 11:50:11 (3536 views) MANUFACTURING - remaining items
- SURPRISE: Wait for cable & re-test overmold (ETA 1 week max)
- WATERPROOFING: grommets still leak, change again (ETA 1 week max)
(the two points above will likely be solved in a last full-day factory visit when the cables arrive there)
- PCBS: find reliable assembly house, we are getting an answer on component duty refund on Monday, but if this ends up taking too long we can hand assemble the first units
