Winner, Name that Ware December 2018

Thursday, January 31st, 2019

The ware for December 2018 is from a 454 Sequencer. The direction of flow is actually from a single input port, splitting into two separate ports, each driven by independent peristaltic pumps downstream of the splitter. The four black boxes are customized Introtek “IntroFlow” ultrasonic non-invasive flow detectors. It’s interesting to see that many readers assumed the flow went in the combining direction, not the splitting direction.

I originally thought the ware was a simple flow splitter because the machine had a single reagent cartridge, and reagents are expensive so if they needed reagents in two spots it would be worth it to include a mechanism for splitting and measuring the flow. But after reading Stuart’s comment, I think he’s probably right, it’s a bubble trap. When I removed the device from the machine, I hadn’t quite traced the pipes back far enough — the inlet goes to a valve that looks like it can either select from a set of reagent sources, or a port that is labeled “air out”. So congrats to Stuart, email me for your prize!

The Ware for December 2018 is shown below.

Finishing off the year with a (hopefully) easy one that’s slightly off the beaten path.

Happy holidays! Stay safe, and stay free.

Winner: Name that Ware November 2018

Sunday, December 16th, 2018

The Ware for November 2018 is a bias/control board for the HP 2-18GHz YIG-tuned multiplier. I really appreciate this fascinating ware, it reminds me that the MOS transistor is not the be-all and end-all of electronics. Of course, every day we encounter crystals as frequency references, and those are literally shaved pieces of quartz, but here is a sphere of Yttrium Iron Garnet (YIG) being used as a tunable RF filter. Thanks to phantom deadline for contributing this ware, and also congrats to Brian for nailing the ware. Email me for your prize!
