This curious sack showed up at my doorstep this Saturday.

Inside was something much better than potatos!

Fabio, No offence but i'll laugh when the hotglue on the speaker gives way over time and comes smashing down on your desk or w/e

I went online, and got a free sample of a peltier, yay!

Messing with HDRi. I couldn't afford buying Photomatix or Photoshop, so I decided to try out Qtpfsgui, which is open source software and works on Linux, too! I got some rather interesting results.

Very nice results! - particularly in the clouds and water portions - better than what I've got with photoshop so far... then again I don't have the option of a cable release for my camera so a lot of my pics become offset

anyways, I think I might give that piece of software a try, because I won't have access to photoshop until school begins next year.

Thanks! Qtpfsgui is really worth a try. It has many different tone mapping algorithms that provide different results. One can produce two differently tonemapped pictures and then blend them together in GIMP. That way it is possible to produce very personal looking pictures.

For the offset problem, Qtpfsgui has a very efficient automatic aligner - I think it is even more efficinent than the one in Photomatix. I haven't got a tripod for my camera yet so I just have to shoot handheld.

Don't worry!

If you look closer, (click on the tumbnail once, a bigger photo appear in a new window, than click on this photo to see a full resolution pic) you can clearly see that there are no speakers glued on the wall but just a PAPER CONE coming from an old speaker.

some metallic items (the hard disk drive and the plates for example) was preheated at about 50CÂ° with a blowtorch or a hot air gun and immediately glued for promoting the adhesion of the hot glue,
finally, the protuding glass dolphin was fixed to the wall with anchor, screw......... and hot glue of couse

Awhile ago I made a snubber circuit for my flyback to help prevent spikes and stuff. I learned 2 things with it.

1: With correct hookup, I get thin arcs, but i can go as long as 5 inch (75V) with a flyback. Multi-stringed 5 inch arc.
2: If reversed, I get THICK ZVS-like arcs from 1 inch (20V) to 3 near 4 inch (75V) Shorter, but THICK and white.

I found that my mosfet never got warm, even without the snubber. However the snubbers resistor gets extreamly hot if its not sinked. I use to have a diode on the resistor, until i found its under-rated. 1000V 1A 1n4001. Poor thing smoked a tad. Put a 1000V 6A on it, nope, still did. So i cut that all out.

as you might have noticed, theres some redish crap all over the cap and the side of the resistor..My first Varistor, well, It kinda had a little issue, super smoke bomb. SO. I cut the varistor off my 120V switch I hacked off a old radio, and well, Doesn't even get warm :) She works! You can also see a 4001 hiding under the resistor :D Too bad its not connected due to overheating.

*Diode connected = Diode hot, resistor cool. No diode, Resistor hot.
