The article was buried in the middle of countless technical specifications.

Last year I was working on a Stacker/Reclaimer (Sort of but not like this) and was reading through the 500+ page customer specification. Buried in the middle of the electrical section of the spec was a paragraph that said something along the lines of:

An ashtray shall be welded to the side of the operators control room.

When I saw that I thought it was probably something similar to the M&M clause.

I bet you did not even use an iPhone, pleb.

And if you read TFA (which I bet you didn't) on the top of the list of improvements is to ditch the iPhone.

Try to get rid of the whole iPhone / Bluetooth setup. I think to do this you could try using a Raspberry Pi with a high speed (60/120FPS) capable camera directly attached. The Pi probably has the processing power to do the image processing.

The "Lame" blog, mine blog, is one of the main authors of the app ( me ).

And respectfully it is lame. I cannot see any link at all to your software on your blog, and the posted images were deliberately cut in half so they lost a lot of context. In order to find out actual details of the software I had to google the name in order to find the actual website. That is a big fail in my book.

The lack of links, carved up pics and "generalness" of the blog make it and the /. story look like pure click-bait.

"...can boost 300 to 400 millivolts power to 3 to 5 volts".

Power? Volts? Boost? Huh???

In common vernacular of an EE you refer to voltage as power with the understanding that there is current being supplied. EG This device is powered by a 9-volt battery. So the the use of power in TFS and TFA is not out of line.

The paragraph form TFA is:

All these ambient energy sources, such as the difference in temperature in a pipe carrying hot water and the outside air, can generate 300 to 400 millivolts, which isn't enough to power anything. TI has built an "ultra-low powered" DC-to-DC switching converter that can boost this power to 3 to 5 volts, which is sufficient to charge a battery, according to Niranjan Pathare, senior marketing development manager at TI.

Also while current is a needed aspect, the level of voltage is a defining factor in electronic design.
