News:
Anyway, the most appealing products of my brain activity came out to be "chempage.org" and "commonchem.org", since both of these options sounded quite lame, and I wanned to give it a rest, I decided to keep the old name.. and anyway, I'm used to the old one.. PS. For those who needs some inspiration here's a good page, that came up in nearest months: Tecnotacho (www.tecnotacho.com). Page contains some original projects with technical descriptions. Something that particularly raises my attention is the Ranque-Hilsch vortex tube, used to separate high velocity air into hot and cold air, that is, by some mysterious way transfer kinetic energy of air from one place to another OO Was planning to change the direction of this page more towards "dry" experiments, that is, less chemistry experiments and more electronic related things and other equally fun projects. The few chem experiments I have, will ofcaurse remain on the page. Oh, and no, I'm not doing this due to problems with the nazi police/other likeminded people. The "dry" experiments would include things like construction of fume hood, different homemade equipement for home lab etc.. Although there could pop up some chem experiment, cause, for example, I'm not finished with the H2SO4 project. This change will come with a change of domainname.. This will be done in middle of summer when the bill for domain comes in. Though I didn't yet came up with any good domainname that would include "basic syntheses", "chem related tools/equipement" and "electronics". After 2 years I realised that "frogfot.com" didn't include any of these things, at least literally it didn't.. Oh, suggestions for the new domainname are welcome, cause I have a limited imagination :) Also, some good news that I've forgot to mention.. Several month ago there was a success on the "sulfuric acid project" front. I've successfully tested a sulfur burner and was able to produce nice amounts of sodium sulfite! Mentioned some more details in a thread on SMDB (18.08.05). Well, H2SO4 synth is close.. Next pre-test will be done with optimally sized caps, >160000uF, as soon as I find these at the recycling center.. I'll probably monitor the chlorine loss through the whole test. Unfortunately the fan in my power supply had other plans.. it died, so my rectifyer cooler started to get really hot. Therefore I did only 45 min testing. Gotta do some fine adjustments in the cell and then do the actual run. This will happen probably when temp outside stabilizes (closer to the spring). This time I'll do some plots of the run and follow the anode corrosion. Ofcaurse heres a plot of the pre-run. Note that y-axis represents all units. I've included cell current, voltage and temperature above both cells, and external temperature. Here are some preview pics of the actual cells: ready cells and anode-cathode block. Cells have capacity of 1,7 l each and max calculated current rating of 21 A. Found that lactose procedure is quite irreproduceable, gonna correct it soon.. Here’s some old news. |
