Re: lighting cage with CAMVATE clamps and arms

This is a cool project, well presented and laid out. Thanks! Decided to go with 2020 aluminum extrusion over the pvc conduit. Picked some up, minus the brackets and fittings. Very impressed with just how rigid this is. So has anyone managed to complete an aluminum extrusion based cube? It's always h...

Re: Looking for least expensive variable 12VDC 8A power supply

Brett, reading your first post I missed the links you used and just read your query. I took it that you were using a dimmer on the AC side of things. These intelligent leading/trailing edge dimmers can be load sensitive. The reason your meter wouldn't give accurate readings is down how it samples. Y...

Re: Looking for least expensive variable 12VDC 8A power supply

Brett, you could try another approach. A cheapo enclosed 12v 10 amp DC power supply (Amazon). A cheapo 12V 20Amp PWM controller (Fleabay). Make sure the PWM is 'beefy' enough. (Plenty of heatsinks is a good sign). So,.... AC in, to the Amazon power supply, The 12VDC out, to the input of the PWM cont...

Good luck with the new buy.

In the field, if you only have 1 flash,
a reflector can come in handy

The newer Led types are limited in use/output. Will have a look for it if you haven't got sorted out. I am based in t...

Re: Misfire of strobe during shooting

I find the point in *not* using any rechargeable batteries strange The transmitter's operation is voltage dependant. It is not a high drain flash circuit. Rechargeables even fully charged will not reach as high a voltage especially in series and will not be seen by the X1 as at full potential. As t...

Re: Tungsten to LED Microscope conversion

Update. So far, so good! Changing over to a LED light source, I needed to lose the old Nikon lighting circuit. I wanted to increase efficiency, provide greater protection and add extra smoothing to the power supply. So I made and installed a new PCB, fitting additional upgraded components. With redu...

What is this fly with legs like a flea?
A quote from 'Rik and the Beanstalk'

'Flea Fly Foe Flung' lol.

When flies turn rogue, really annoying, in your face. Like they have a death wish,
I have heard them called 'D*mn Flies'.
This has got to be one of those D*mn Flies!
