Name that Ware, August 2020

August 31st, 2020

The Ware for August 2020 is shown below.

While sending me an unrelated photo that I will feature in a future Name that Ware, David Willmore nerd-sniped me with this incidental photo. It is as of yet unidentified, but as far as I could tell it’s from a short-lived family of 1969-era Texas Instruments “DRA” — a Discretionary Route Array. Basically a wafer-scale bipolar gate array (back when “wafer-scale” meant one 1.5″ wafer — hence the circular boss in the middle of the package), which could run at speeds of up to 10MHz. For example, the DRA-2003 was a dual 501-bit shift register, and cost $390 back then in 100-249 unit quantities (around $2,800 inflation-adjusted). As an interesting side note, the rule-of-thumb pricing for a single processed 12″ wafer today is … about $3,000. That’s Moore’s Law for you: 50 years got us roughly a billion times more transistors on a single wafer of 64x the area for about the same cost.

I couldn’t find anything on this specific part number (DRA-2009E), so I figured why not turn it over to Name that Ware to see if anyone could come up with more details, about the logic family itself, or ideally about the specific part number shown here.

Winner, Name that Ware July 2020

The Ware for July 2020 was a PocketVNA. Congrats to Jean for nailing it! email me for your prize. I acquired a PocketVNA a little while ago to try and tune some antenna for the Betrusted project. It has some quirks and limitations, but for the price it was a good value for the capabilities it brings.

The Ware for July 2020 is shown below.

This ware is ever so slightly cropped to hide the connectors on the edges, which would make it way too easy to guess.

Winner, Name that Ware June 2020

July 31st, 2020

The Ware for June 2020 is an Elcotel Series 5 payphone. Apparently it was found vandalized in a parking lot, and so a few pictures of its insides were able to find its way to me via Bob Parker (thank you!). I always wondered what was inside these payphones, now I know. Gratz again to jackw01 for nailing it, email me for your prize!

On Liberating My Smartwatch From Cloud Services

July 25th, 2020

I’ve often said that if we convince ourselves that technology is magic, we risk becoming hostages to it. Just recently, I had a brush with this fate, but happily, I was saved by open source.

At the time of writing, Garmin is suffering from a massive ransomware attack. I also happen to be a user of the Garmin Instinct watch. I’m very happy with it, and in many ways, it’s magical how much capability is packed into such a tiny package.

I also happen to have a hobby of paddling the outrigger canoe:
