Production Date and Combining Outputs

August 19, 2014 in 8 Channel PDU

It looks like I should have units in hand about the second week of September. This video also shows how you might setup an air horn (or other high current load) with Motobrain.

Production PCB Test

August 6, 2014 in 8 Channel PDU

I built up a Motobrain using the production PCB and preprogrammed chips to confirm we are on track when the manufacturing begins. Everything looks great. Time to ship the parts to the factory and get these things built!


Automated Test Fixture

August 2, 2014 in 8 Channel PDU

The automated test fixture is ready to send off to the factory. The rest of the parts for manufacturing will arrive on Monday I believe. Once they arrive, they will get boxed up and shipped to Florida.

The test fixture is used to confirm the electronics are all in working order before they are encapsulated.

First production units ordered

July 10, 2014 in 8 Channel PDU, Featured

I ordered parts for 100 units on Monday and submitted a purchase order with a contract manufacturer in Florida to do the work. Half the parts have already arrived. The production waits until the final parts arrive though. In this case we have parts coming from Japan, China, and Germany in addition to those coming from on shore distributors. The parts from Germany are heavy (the screw down terminals) so they are coming by ship. They leave the harbor tomorrow. I suspect we will have everything in hand within 3 weeks.

I pulled what will be among the last prototypes I make out of the mold this afternoon. It is the first I’ve made with the new insulation between the terminals. I am pleased with it. This innovation is thanks to reader feedback. I want to thank you guys for the help.


New Motobrain Mold

June 17, 2014 in 8 Channel PDU

As requested by you guys, I’ve added separators between the outputs to prevent accidental short circuits there. It looks pretty good to me.

Because the factory production samples were unusable, I ordered some new PCBs yesterday and will be hand building up some new Motobrains for this case next week. The factory that failed is considering rebuilding the samples on their nickel. They are in China and I therefore have little recourse other than my future business. If they can actually deliver I would be excited though because their pricing is good. I’ve also requested another factory to build some for me in case the first one decides to cut and run with my money after the first failure. I should have some volume of samples in the not to distant future one way or the other. As soon as I have evidence that someone other than myself can build them I will be ordering 100 units which will be going out to early adopters and market mavens who will be testing the product for me.

New Motobrain Mold


Production samples are junk

June 11, 2014 in 8 Channel PDU

The samples that arrived on Monday are trash. The photos of them look okay but upon closer inspection they appear to have been made by incompetents who don’t give a hoot. That is to say that not only is the skilled labor done poorly but so is the work that only requires attention to detail. A waste of time and money. No one ever said building a global supply chain was easy!

Production Samples Arrived

June 9, 2014 in 8 Channel PDU

The production samples arrived. They look pretty good though I am not certain they were actually built on machine as I expected. The factory building these samples by hand tells me nothing about the quality of their machine assembly which was the entire purpose of this exercise. That is a bit of a disappointment but not the end of the world. I’ll begin testing them this week. Finger’s crossed.

I also got the new mold master which has insulating tabs integrated into the design to protect from incidental short circuits. I expect to have 5 new Motobrains ready in short order for testing.

Production Samples

June 3, 2014 in 8 Channel PDU

Production samples of Motobrain boards from a fabricator in Asia are shipping in the next few hours. I’ve already received PCBs samples of the heavy duty power boards from a couple of suppliers in Asia as well and they are getting close. Some are great but too expensive, some are the “right” price but are missing on the quality side of things. I am still working those details out but suffice to say, things are progressing nicely. I’ll post a report on how the boards turned out when they arrive at the lab.
