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.

legoROBOLAB Posted yesterday at 08:59 AM Posted yesterday at 08:59 AM This is a great step towards the universal use of interfaces, namely B. I greatly appreciate your work. Continue, The last LEGO Education product, to be released in September 2026, has an identical type of language. This is modernizing the old LEGO sets. Thank you again. Quote
