Re: Fusel side draw experiment

Just wondering how you arrived at 100mm? Was it just an educated guess? (8% of column height) Seems like your results suggest it be placed higher up, possibly at 20 or 30% of column height? I have switched from lava to marbles and need to find some takeoff that would be compatible with marbles and ...

Re: Fusel side draw experiment

Zapata, this started as a test to see if these kind of cheap pumps can be used as a needle valve. The fusel draw experiment was a nice spinoff. As stated by me earlier in this thread you can do the same with a take off and a needle valve. I am modifying a still at the moment and I am thinking about ...

Re: Fusel side draw experiment

But instead of building an bleed off, an additional run could solve the problem too perhaps? You are right however a bleed off (could also be a miniature funnel with an elbow and a needle valve on the outside of the column) is a one time modification and on the long run more economical. What abv is...

Fusel side draw experiment

For a theoretical background for this experiment see ABV dependent volatility of fusel oils ketel3 and I did an experiment with the objective to test cheap peristaltic pumps as a substitute for a needle valve and to find out the effect of removing the fusel alcohols (tails) oil through side drawing ...

Re: From vapor temperature to vapor abv

The eeprom is 8 bit. The array in the eeprom consist of 16 bit values. First value start at address zero and occupies two bytes, next value starts at address two, etc. Thats why the index is multiplied with two to get the right eeprom address.

Re: Need an EE's help with hacking a SCR (I think)

This post will give you some information.
I looked into interfacing this with an Arduino but the 5V for the controller is not galvanically separated from the mains. So I think it's better starting from scratch. Maybe this is useful.

Re: How/where to add Voltmeter to Heater element ckt?

In parallel on the mains only.

If you connect it in parallel over your element this voltmeter will smoke :( , see this thread.

This makes is not so useful as you will only measure the 120 or 240 Volt of your mains supply.

If you wire your PZEM-061 (or any similar power meter) after your SCR it will smoke :D
Wired correctly the displayed power is the real power dissipated by your element and your SCR.
