sentients in space [Jan. 31st, 2010|06:52 am]
electrictruffle
I thought that this XKCD was cute, but it triggered a bit of a Moxy Fruvous earworm: 'When I was three they put a dog in space, and left it there you should have seen her face...'

Sorry Spirit, you done good, but I've more emotions for Laika.

Time to visit Boston.

Time to show off the spawn.

Time to give N a vacation from all kid wrangling.

I'll be in Boston from Tuesday to Tuesday spanning the October/November transition.

Let the visiting begin.

pressure vessel design [Mar. 23rd, 2009|07:34 pm]
electrictruffle
I know just enough about pressure vessel design to be _very_ dangerous, especially now that I have access to a metal lathe and milling machine.

I would like to build a small (500 - 1000 ml) 50-70MPa vessel in stainless steel for use in the liquid nitrogen to boiling water temperature range. It needs to be relatively long and thin, ideally with a closure on one side only. This is for hobby use (cooking), so I can't really convince my employer to build/buy such. I know enough to estimate the wall thickness that I should be using, calculate the energy being stored, and get very scared.

Would anyone with suitable background be interested in trading design time for some very good chocolate truffles? I don't need fabrication, but design assistance to make something safe that I can fabricate. This means no welding (no way I can make suitable welds for this sort of use), and should be something that permits proper hydrostatic testing after fabrication. This project is in support of my confectionery art.

Job Networking Ping [Nov. 23rd, 2008|08:41 pm]

I am sending out a couple of feelers here hoping to bring in a few extra dollars...though if this leads to a large enough influx then it might facilitate my return to the North East....

N is a statistics/data wizard looking for consulting gigs or salary positions where she can help people understand large interesting datasets. She has masters in both Mathematics and Statistics, and 10 years experience helping semiconductor fab engineers understand their process datasets. Her experience involves understanding the statistics, presenting the data and the statistics, and visualizing the data in ways that can be understood by both the engineers and their associated management. Rather than limit herself to semiconductor fab, she is interested in applying her statistics experience to other fields, eg. bio-informatics.

I am a general 'build it' wizard, with experience in PCB design and electronics, electric motor design, small submarines, LED lighting, chocolates, tutoring, sewing, patenting, home repair, chemistry, and on and on. I'm looking for part time consulting work or commissions.

Ideally we are looking for things that we can do from Portland, or things that would pay well enough to suport a cross country move.

If you have any suggestions, leads, comissions, requests, etc., please point them my way. Chocolate bribes can be arranged.

truffle lottery [Apr. 18th, 2008|08:19 am]
electrictruffle
I have some chocolate to get rid of pre-pesach.

Who wants?

Okay, you all win, but because of the way postage rates work, everything is going in a box to Andor. Ceo gets a box with vanilla truffles and some hazelnut praline bark. Ruthling gets a mix of vanilla and _unknown_ truffles (in the small bag, possibly habanero), and andor gets vanilla truffles, hazelnut bark, and 'dark and bitter' bark. Or 'Dark and Bitter' can be someone else :)

Magid: you will have to wait until next year. We checked with the local kashrus supervising rabbi, and straight chocolate liquor is kosher for passover without any supervision beyond being kosher (similar to cocoa powder). Callebaut also has a kosher for passover semisweet, and possibly a bittersweet. Next year we will have good pesachdich truffles.

livejournal bouncing my email [Feb. 20th, 2008|08:30 am]
electrictruffle
If the e-mail address that I have for you is @livejournal.com, then you will not get messages from me. Apparently my companie's system fails S25R rule one, probably something to do with reverse DNS. I will be investigating this on our end, however this means that a number of messages have bounced.

Primarily these are messages relating to my visit next week :( Because of the way S25R works, it took almost a week for the messages to bounce.

Zot! shorn [Jan. 20th, 2008|08:34 pm]
electrictruffle
For A's birthday, I decided to make a Jacob's ladder cake tray. The idea was to have a climbing arc in a lexan tube coming out of the center of the cake, sort of the ultimate birthday candle. Owing to difficulties obtaining an appropriate transformer, I couldn't pull this off in time, but I did get to show off a mockup, which the kid thought was quite cool.

For other's benefit, the transformer is an Allanson 2275-456 oil burner ignition transformer, guaranteed to strike an arc across 1/2", and cheap at about $30. 17.5KV, 45mA, and nice looking arcs.

The image shows multiple arcs because of the exposure duration. In reality there is one climbing arc, that is seen several times here.

My thinning (bald) spot has grown, and I decided that I had enough of the incipient comb-over. Time for short hair and pride!

The hair cut had nothing to do with the Jacob's ladder. Not one bit.

Burningman! [Jul. 15th, 2007|09:56 pm]
electrictruffle
After 15 years of hearing about this crazy thing, I'm finally getting my ass in gear and going to Burningman.

7 weeks to go, and I am not nearly prepared, but I am going with someone who has gone before, and I've already started gathering the appropriate tools.

My sister has just moved to Reno, which makes some of the logistics much simpler; anything standard that I am buying (IE things that I don't need to try out first) can be shipped to her.

Anyhow: I don't have a camp to go with, and was wondering if any of my friends of friends have suggestions. My 'art' will be to bring truffles, keep them from melting, and giving them out.

glycerol [Jul. 6th, 2007|10:06 am]
electrictruffle
Glycerol has a melting point of about 17C.

It has a specific heat about 60% that of water.

It is _cheap_.

It would be a _great_ phase change material for chocolate transport, but for one serious problem. It supercools. In fact, it does such a great job of supercooling that it is used to protect biologicals that are being frozen.

Does anyone here know how to _force_ glycerine to actually _freeze_?
