Add a thumb screw to your ProdMod Camera Light

ProdMod Camera Light with 3/4″ diameter thumb screw

It’s not rocket science, but for those of you who prefer running a screw through the body of the light, I thought I would share some photos to show how a simple thumb screw might look. It looks a bit better than a simple cap screw depending on your taste and these screws are about 1 dollar or less.
If your camera tripod mount is near the center you can also set the camera down on the screw head as shown in the photo. You can’t do this with a cap screw.

Continue for photos of a rosette thumb screw and part numbers for both types.

ModThis: Trisonic Wireless Window Alarm: WinMoney

Sometimes you come across a product that you might not really need but its so inexpensive that you know you can find a use for it in one of your projects. Or at minimum harvest it for spare parts. Well I found such an item today. It’s the Trisonic Wireless Window Alarm. It has a magnet that basically turns on the alarm when its moved away from the base. You can probably find these in thrift stores and also on ebay.

I took it apart as soon as I got it, took some photos and it looks really simple, just analog components. I am not sure what I would do with mine just yet, but I bet some of you can come up with some creative ideas. So make something and WIN $20.

Updated! - Brighter LED Camera Light and with one touch PWM dimming

Its been a while since the last ProdMod LED Camera Light update. I was going to review some brighter LEDs by comparing different brands and technologies. Like Hi-flux LEDs and 1W LEDs. I was also going to go over different ways to dim the LEDs like using a simple potentiometer instead of a resistor near the LEDs or in place of a resistor in the Voltage regulated Vpack. Then I was going to discuss how PWM dimming is better. Well instead of taking you through all those steps, I decided to just show you my latest development. It is a 1W led with PWM dimming control.

So here are some videos that show how much light the ProdMod Camera Light can produce with only one 1W High Power LED running 350mA, and the second video shows the continuously variable dimming that the PWM control allows!
