Early-birds Shipped 2 Weeks Early, All Surveys Sent
First 500 Arrived
On Friday 13th May, the first 500 RasPiO Pro Hats arrived from China...
...so I set about testing them.
Manufacturing Trials Are Important
I was very anxious to see the failure rate. In round 1 manufacturing trials 13 from 60 boards failed. That was rather scary! But the problem was identified and improved upon. Round 2 had only 1 from 15 failures. At that point a thicker solder stencil and more rigorous visual inspection was agreed upon for production. As you can imagine, I didn't want to have a 20% failure rate. So I tested ~120 boards on Friday. This is how they are tested, in case you're interested...
It wasn't until #88 that I found a failure. I'd told the factory that a maximum of 1% was acceptable. I tested a few more on Saturday/Sunday and the last 200 on Monday. We had a grand total of 3 fails from 500. YAY! That's well under 1%
So while I was finishing the testing, my wife Mal packed 243 early-bird rewards into the padded envelopes we'd pre-prepared last week. I had hand-delivered 3 to Mike, Tim and Brian at Potton Pi and Pints on Saturday...
So the Early-birds are Shipped - What Next?
The early-birds were all shipped on Monday (a couple of weeks ahead of schedule). The next category to be shipped will be the £25 reward - Experimenter's kits. This category was surveyed last week and nearly everyone answered already. These will go out in the next few days.
Now we will have to wait for the rest of the RasPiO Pro Hats to be assembled and shipped from China (and for the responses to the rest of the surveys). We are comfortably ahead of schedule and aim to get these out to you as soon as we can. It will probably be a couple of weeks before we receive them.
All Surveys Now Sent Out
All reward categories have now been surveyed. Please make sure you have completed your survey. Then we can have everything ready in advance of when the remaining Pro Hats arrive.
Pro Hat Arrival Tweets
Once you received your RasPiO Pro Hat please feel free to tweet a photo. It's always fascinating to see how quickly the postal service delivers around the world.

Heads-Up - New Project Next Week
Next Tuesday (24th May), I'll be launching a new project. I'm aiming for 0900 BST kick-off. I'll send an update shortly after launching to give you all a fair chance of snapping up an early-bird.
Thank you once again for supporting the RasPiO Pro Hat project.
