This looks very nice experiment, I’m going to try this. though I’m still beginner in all these issues.

If your’e looking for an efficient, inexpensive portable heating unit, you might want to review two units @ http://www.porta-lab.com. The model MF-2001 can be used with the round bottom carafe. The model HP-2003 (Gas Hot Plate), Works great with the flat bottom units(ex: Bodum Santos).

@Yeeza

I know you’ve got a ‘proper’ fancypants one now – but if you want a coffee pig for one, I’ll snag it when it’s completed?

mental note: ask you about it when you’re back from your travels.

This is really cool! I had to make a halogen heater for an electronics project and it worked out quite well. I have managed to get most of the parts I needed for under $10.

I think the link I previously posted didn’t lead to the right place. Here’s a relevant quote from Wikipedia:

“For practical applications, the efficiency of the infrared heater depends on matching the emitted wavelength and the absorption spectrum of the material to be heated.

For example, the absorption spectrum for water has its peak at around 3000 nm. This means that emission from medium-wave or carbon infrared heaters are much better absorbed by water and water-based coatings than NIR or short-wave infrared radiation.”

I had a chance visit at one of the famouse coffeehouse in San Francisco last week.
Technical advised by UCC-Ueshima, they have set up a nice looking 5 syphons counter.
I do now know about a any knowridge about syphon brewing, but druring brewing, staff used
a stick to mixes coffee powder and hot water.
Is this a right way?
This coffeehouse also set up a drip counter, they also used a stick to mixes inside a dripper duering drippin. I just wondering that why they doing…..?

Yeah that’s me :)

Reading this thread has made me want to attack it properly again and source all the right pieces and make up a proto-type, 240VAC 50Hz version.
