Finally, I found a DC-DC converter that is powerfull enough to drive a camera from a USB powerbank. The powerbank has to provide at least 3A at 5V to satisfy the power consumption of the camera during shutter release.
The converter is small enough to be built into the adapter on request.
The Austrian Society for 3D Printing started a project to support mastering the current COVID19 crisis.
Persons or institutions operating 3D printers were asked to provide printing power in case demand for 3D printed items arises. We are printing now holders for shield masks that will be delivered to schools.
Again, I updated the LED Strip Controller. It features an additional light effect that allows configuration for wider arrows pointing at the lens. It may be configured as a single arrow, a symmetrical pair of arrows and runing in a bar across the area or filling up teh area with a color.
Again, I updated the LED Strip Controller. It features a new light effect that allows configuration for arrows pointing at the lens. In addition, the LED Strip Controller is now able to drive up to 500 LEDs. Please note, that a really strong power supply is required for that number of LEDs!
I designed a new controller to show light effects on a photo booth. It drives segments on LED strips to allow effects on arrows, the printer slot, buttons or similar. The controller is an add-on to the LED Ring. It is controlled by the LED Ring Service that synchronizes light effects with most common Booth applications.
