I was thinking about how I can put light where I need it during camera and lens checks. And free a hand that has better things to do than hold a flashlight.
So I was looking for a convenient and powerful solution, especially for checking and cleaning the battery compartments of my Canon T90s and motor drives.
Because at the bottom of these dark and narrow shafts are the battery terminals that supply camera resp. motor drive with voltage. These contact are often dirty or oxidized. Then the device may not power on and a check and clean is due.
This requires light and two free hands.
The idea for the Illuminator was born to support these activities.

All information is of course without guarantee. What worked in my case may not work in others. Or there are certainly more suitable procedures. Reproduction and operation at your own risk. Circuit design errors cannot be ruled out. Devices to be tested must be voltage-free, observe safety regulations when handling electronic devices. Avoid short circuits. Operation only under supervision, set main switch to OFF when not in use. Remove the battery/disconnect the switched-mode power supply if the vehicle is left standing for a longer period of time. Components can be overloaded when operating at higher ambient temperatures - risk of burns and fire. LED light can dazzle. No liability is assumed for the proper and safe function of the circuit and its application. Not a commercial/professional/certified and tested device/circuit, hobbyist project.

Characteristics of Illuminator 5.0
- Two glare-free matt white LEDs for illuminating battery compartments.
- Two super bright white LED controlled by timer for candling through lenses/illuminating aperture blades. Start via push button, running time approx. 30 seconds bright, automatic dimming or manual switch-off via second push button (only by optional operation with switching power supply).
- Light guidance via connection wires enables flexible positioning of the LEDs.
- Power control of the battery bay LEDs automatically depending on the ambient light or manually.
- Operation with 9 volt block battery or 9 volt switching power supply.
- Automatic switching from battery to mains operation when plugging in the switching power supply plug.
- Two control LEDs for displaying the currently active power supply.
- One control LED for indicating power on battery bay LEDs circuit.
- Stabilized input voltage enables uniform brightness with battery and mains operation.
- Battery voltage tested down to 7 volts.
- Analog circuit, assembly on circuit board without housing, basic version.
