Title: Photography stuff

Better photo with the camera attached to the holder. I also tested how it would hold the big DSLR and it felt quite ok, but I'm not going to use it like that anyway. Tested it like that just for fun and to see what would it look like :)

Took some more video clips and I'm going to upload some of them and I'll post a link then.

First video test from last night: http://www.youtube.com/watch?v=p4qFmy-e81E

I built a camera holder to my bike for my Canon Ixus 80IS mainly just for fun and to get some biking trip videos or what comes to mind. It was supposed to be just a simple holder but once again things got a bit over-engineered :) Little bit of refining has to be done on the springs but good for now.

The brownish thing on top of the aluminum is some cork mat that I cut to be under the camera so it stays nicely in place after the screw is tightened. The bent thick steel wire in the back is used to position the angle of the holder and to give some support to the back side of it. The holder has some offset from the center so that the lens of the camera is in the middle and in same line with the front tire etc.

I went out for a test ride with it after I got it finished. It was already quite late at night so the video isn't the best possible. I'll post a couple more photos tomorrow maybe and a day time video test if it doesn't rain.

DIY panorama bracket for my camera. With this the turning axis is about where the first lens element is on the lens so it helps in panorama photography.

The bracket is made out of two pieces of 5 mm by 40 mm aluminum, the bent part is 24 cm long and is bent at the middle. The straight part is about 15 cm long. After finishing I covered both of the parts with hockey tape to give it a nicer surface so it wont feel so cold when using without gloves outside when it is cold there. Total cost was maybe around 3.

More DIY photography stuff, this time a better version of the off shoe flash cord I did last year.

I wanted a flash cord for my camera that would have all the four pins to get all the information between the camera and the flash to go right. I didn't want to pay about 60 for a commercial one that has just two connectors and a cable so I decided to make it myself. The commercial one looks like this:
http://www.paramountcords.com/prodimages/shortsc28.jpg

First I started by cutting and shaping a piece of 1 mm thick aluminum to get a body for the flash shoe and after that I started building the connection part of it on a prototyping board (dot coppered). After all that was done I assembled them together and filled the hole thing with hot glue to give it some strength (I could have used epoxy for better strenght but didn't have any at hand). The tripod mount is done from a 4 mm thick piece of aluminum and then drilled and threaded.

Camera side of the thing is done from various pieces of plastic superglued together. I got the springs and studs from an old flash shoe adapter.

The connectors are PS/2 connectors (or mini-din, used in keyboards etc). I left the cables that short because I can use a normal PS/2 extension cable with this. Cost for this project was 0 (all the material I used were found by looking around the apartment) so now I can use the saved money to something else useful. :)

Macro photo of 486's core. The size of the area on the photograph is about 2mm*3mm (so the text "80486" is very small, less than 1mm wide). Photo for the test competition.

This is my FlashSyncBox what I built almost all the day yesterday. I can connect up to four external flashes to it (the four blach RCA-connectors on the back) and then connect the box to my camera (the red RCA-connector on the front) so every flash will fire simultaneously. I can also connect other triggers to the box instead of a camera (a sound trigger for example). This will help me with my photography hobby because now I can light things up more creatively. The box with a sound trigger would be excellent when taking high speed photos, like an air balloon exploding for example.

First I designed a pcb for the box and then printed it on a transparency sheet to use it as a mask when exposing an uv sensitive pcb plate. After that I developed and etched the board and soldered all the parts to it. I used an empty 2.5" USB HDD case as a case for the board because I had it lying around without any other use. I cut about 2cm off from it to make it a bit smaller. The device gets its juice from the 3V lithium battery inside it or from an external power supply (the power switch toggles between those two).

Dimensions: width 75mm, height 13mm, depth 105mm (124mm with connectors).
Front of the box: A test button to see if the device works (every connected flash should fire when this is pressed), sync connector (camera or other trigger), power switch (left: internal 3V lithium, right: external power), external power connector (3-6 VDC).
Back of the box: Connectors for four different flashes, can be a new flash with low trigger voltage (4-10V) or an older flash with high trigger voltage (100-250V, maximum is 600V as the thyristors I used are rated at that).

Started my studies in another city and moved to my own flat, so here is a panorama shot of it. Outside of the picture there is the door of the "french balcony" on the left, kitchen behind me and the light blue door on the right leads to the lobby and there is the toilet, a clothes closet and the way out etc. The bunk is self made from scratch to fit nicely in the alcove and there is my building desk under the bed. I'll post a desk shot later.
