A lot of time was wasted on the motion control system again in 2013 but I think we have a solid solution going into 2014 even though it hasn’t been thoroughly tested yet.
I am sitting on a lot of inventory because of these experiments. Please check out my eBay store if you need any industrial automation components!
Also found that all USB hubs are not created equally. I bought a cheap 7-port unit from China and it ended up having a bum port. I got a full refund but am still using that unit because it works more reliably than a pair of cheap 10-port replacement units that I purchased. Now I am convinced you have to spend $3 per port instead of $1 per port.
