Chip

Saturday!

Today I am going to try to make some triggers for different conditions; Lightning, Sound and Beam-Interupt. They will aid in special photography sessions for storms, broken lightglobes, bursting baloons etc. Cool.

In other news I put together one of my metal-halide lights today. Damn they are bright! 150W Floods. They are going to be very helpfull. I modified my old tripod to mount the fixture (lighting terms - the enclosure for the lamp) on the tripod and hang it's ballast from the bottom centre of the tripod. This particular tripod has a rubber plug in the base of the vertical slide. I took this out, drilled a hole, inserted a screw + bolt and cable harness.

Screw->Flat Washer->Cable Harness->Plug->Shakeproof Washer->Nut

This is re-inserted into the vertical's base and the screw tightened so the plug is compressed, securing it very firmly. This was required because the ballast weighs about 2Kg. The ballast was hung from the cable harness using two cable ties.

Pictures Later.

With all this experimenting and no breakfast of coffee, it has occured to me that I am hungry. The cripping imploding stomach feeling also indicates this. Hrm... I really should have a rest and eat something =) But there's so much more experimenting to go today! I need to get my breadboard out and a PC powersupply.

Another thought. BUGGER! I didn't buy any 7809s (9V Regulator IC). I hope I have some in my semis box. All the circuits run off 9V and I don't have my Lab Powersupply yet.

More thoughts. I need a CRO.

2:49 PM:
Finished off the light. The method seems OK. I need to purchase some cheap-arse tripods to put lamps on.

It works quite well. Bloody bright! I want to get some 5000K globes for them now, the ones in there are 4200K which is just under daylight. About time something worked out in this shit-house week. Sick

7:31 PM:
I took some shots lit with my new light staring my new pint mug =)
