For reference, here is the ghetto way to make linkable thumbnails.

1. Add width=400 to the opening img tag.

2. Enclose the img tags in url tags pointing to the same link.

Before:

[img]http://hphotos-snc1.fbcdn.net/hs245.snc1/9223_1236464717713_1412082993_686482_6241018_n.jpg[/img]


After:

[url=http://hphotos-snc1.fbcdn.net/hs245.snc1/9223_1236464717713_1412082993_686482_6241018_n.jpg]
[img width=400]http://hphotos-snc1.fbcdn.net/hs245.snc1/9223_1236464717713_1412082993_686482_6241018_n.jpg[/img]
[/url]


There's no cute button for it, you have to edit the BBCode yourself. I did your first one for you.

The preferred way is simply to post the pictures as attachments, then the forum software thumbnails them for you.

Some eye candy:




I grew over 2 months, large crystals of the air sensitive compound FeCl2 and recovered them today. I *was* going to use the FeCl2 for ferrofluid synthesis, but now I'm just going to store them cause they look *awesome*.

What is that largest one? The internal structure looks like the GU-81M, except for the bottom internal part :P.

It's the GU-80, an earlier version of the 81 I think.

Had a little surprise during my Judo training. I got this award for my works as a volunteer for the local Judo club. It was handed out by the municipality governing board. They had an independent jury that selected me in the category juniors from the 6 villages.

You're going to have to flame polish that hole because any small crack in that glass is the start of a fracture point. After you polish the hole you should anneal the glass too.

You could also try grinding it to a fine chip free finish and then preferably polish it, thus avoiding any heat treatment. Wet & Dry paper will do.

In July-Aug, the same Calif. location will be 104F (40C), 50% humidity, sky brown with smog. And then there's those pesky earthquakes...

Chico was also very pretty in spring, and total hell in summer.

here is one of my first Large Format photographs,
camera was a rented Horseman 45FA with a Fuji 210mm lens, film is Ektachrome 64 (4x5 inch sheet size and expired in 1990!), image scanned in to a 150MB TIFF file @ 8142x6440 originally (can't post that here lol).

The subject is a flower in my backyard, but I tried to make it a more dramatic image using camera settings, and I think I did a pretty good job for my first time using this film and camera!

I would have more, but the ones that survived the TSA opening my film box have yet to be scanned, and the ones at the lab won't be ready until Monday. (They opened it on accident, as they had no idea what to do with sheet film, but then again I shouldn't assume they'd ask)

-Jimmy




EDIT: Whoever responds to this gets to be post number 2000 in the "Post your cool pic here:" thread!!

EDIT #2: I would hate to have to take post number 2000 in this thread, as I have post 1999 - but I get my other 4x5 film sheet scans tomorrow and if no one else takes the legendary post I will!!!

My new toy, and it unleashed against a razer blade...




The resulting hole I cut, and a shot of the cut edge. The spot size for that shot was about 250um, and the power was about 40w quasi-q-switched.

forgot to congratulate "..." on getting the 2k post mark for this thread!

here are some more Large Format Photos I got back from the lab... The first one is my also my first successful long exposure start photograph, exposed for around 15 minutes; the second one is a photo of a tree at my school (the sun washed out though) and the photo beneath it is a subsection of it. With large format photography, it is possible to take very small sections of the negative and make a good quality image; The next one is of a cactus grove, and the one below that is, as with the tree, a subsection of the first one. This one is not as good quality, mainly because I threw the focus off a bit and it is a much smaller section.

-Jimmy

Another successful trip to the recycler. This time stacks of capacitors [low ESR (30mOhm) & low ESL (17nH)] all at 2,200uF @ 500VDC, lots of flexible 1000V 1/0 & 4 AWG jumpers, lots of copper bus-bars, 2mH @ 120A chokes, all sorts of stuff in pristine condition - ex-equipment but never used and now decommisioned...

Photos of some of it:

Finally got my Class-E SSTC case underway...For those who want to know, it's a Hammond Diecaste aluminum RFI/EMI shielding case. So far all is going well on it, Capacitors and transformer is mounted down, currently is going to support 60V doubled (Yes i know this is mains power but i wanted limited amperage) Later if things go well, i may consider mains or mains doubled.

I also on Friday got my 200mW Green laser, yay! Sadly the battery ship separate for FDA reasons, those come Monday or Tuesday. And yes, I do have proper IR / Green laser blocking glasses...Don't want to fool around with a 200mW without them.

It's been a very long time since I posted here... 2008 I believe. Been following though. The reason is I gave up most, if not all of my HV, Tesla, mechanical TV and radio hobbies was to persue a new one. (Had to sell everything and raise cash somehow.)And what a good thread to show it off.
Snooch was originally a 1990 Suzuki GSXR1100L. Now its a 1216cc, blow through turbocharged, 125 octane fuel drag bike. Now at Mk3 and by the weekend will be Mk4.
Between 220 and 380 BHP depending on boost setting.
I'm in my second season running in the ACU 9.50 second class.
The bike will run 8 seconds, but not with the swingarm seen in the pictures. That's now off and a 72" wheelbase one going in its place.
All mods are custom made by a UK turbo guru and personal friend.
Hope you enjoy it... Cheers. Mark.

Ohh, nice Gixxer, Baird! I would give up most of my projects to pursue the dream of building the dune buggy, but it's 7 grand for the frame and associated parts, and 2k for a used Hayabusa engine. Hopefully one day...!
