Scorpius factory mess up!
#1

$&#%!!!

A day in the life of a tech developer Ambulance
So John took 4 weeks off to go to Canada and on return I sent him the MPDV5 decoders. Testing was going ok until John went to test some 3.3V circuits only to find they didn’t work. However all the 5V circuits worked fine.

It took a lot of detective work. The components we’re talking about are 0201 which are 0.06x0.03mm.
Too small to remove and replace. Even for a pro. 

John used a macro lens to photograph the components but the numbers are not clear or missing. The part concerned is a resistor.

Anyway by comparing outputs of various sub circuits between MPDV4 and MPD5 John was able to deduce one of the components was incorrectly loaded into the pick n place baskets the robots use. Factory error. V4 worked fine.

However the factory is not convinced  and they also cannot see the part number. Hmmmm.
Looks like Scorpius will have to take the hit and move forward. So onto another rapid prototype company and wait 4 weeks.
Will it affect time frames? A little. Cost so far 6 hours. 
Overall we can keep busy for 4 weeks doing a heap of firmware work using MPDV4 so no it won’t affect us overall. Phew!

The cost? 20 prototypes? That’s life. That’s development. 86 parts are on the MPD and 85 were correct. Fail.

However, positive thinking:
Every error, once recognised is a step closer to completion. And that’s how you have to look at it.

Any hey there’s 2 tweaks I thought of so why not take advantage of a bad situation and get these added in now.
And we brightened the rear lights up on V4 but it’s still needs to go a fraction brighter so let’s take advantage once again and get that upgraded while we’re at it.

John as usual pulls it altogether. He was able to fix the boards. Amazing!
Still a resistor upgrade required but that’s zero cost.

As of today MPD4 firmware was altered to fit onto MPD5 and MPD5 is officially born.

Also as of today the Nitrous car decoder is officially alive with Scorpius and Carrera protocols running simultaneously. Therefore Nitrous will be ready to beta test shortly.

Now a shed load of configuration firmware is required. Lots.
