Spoiler And of another kind of course: In our PChem lab for second year students, we do fractional distillation (some call rectification) of a three component mixture of liquids having close boiling points. When I actively ;) took such a lab 40 years ago, uhm, we exchanged the multi-component mixture with denaturated ethanol. Back then, pyridine was frequently used the denaturation compound. Well, the 2 m rectification column in the PChem lab was well suited to quantitatively separate these two, resulting in a 96% ethanol/H2O mixture. Upon addition of some tonic water etc. ... Thank you very much, Evan! All the best Thorsten Quote
evank Posted January 21 Posted January 21 You're welcome. A few weeks ago I happened to see on Facebook Marketplace that someone a couple of hours from me was selling a massive haul of Dacta sets. He wanted a substantial sum. We negotiated a deal and I drove out there. I don't need most of the sets (so I'm trying to sell them: https://www.eurobricks.com/forum/forums/topic/212437-fs-several-early-dacta-sets/) ... mostly I was willing to lay out the money because his stash of rare Lego educational manuals was overwhelming.

I have an Interface B on my desk, running an ESP32 interface with Python (usually acting as a MQTT switch and indicator for a lamp), but this make it an easy-swap dual purpose CL test bed now.

It can also be modded and translated easily to any language. Edited Saturday at 10:46 PM by amine Quote
