LED Ring Controller now as Windows Service

I overhauled the LED Ring Controller. It is now available as Windows Service. It runs in the background and can be started automatically at system startup.

A new function has been added to the LED ring firmware. It now supports a free running automatic countdown function. This allows to use countdown in Breeze or Darkroom Booth.

To support applications that can only call commandline functions, a helper application has been added.

The latest version of the software and firmware is now available on my website.

Hoodman eyecup for the OM-D E-M1 and E-M1ii

 

OM-D E-M1 ii with Hoodman eyecup.

Wearer or eyeglasses know what I’m talking about. The standard eyecup doesn’t shield stray light good enough. Hoodman developed an eyecup that is huge enough to shield the eye even when wearing glasses. Unfortunately, it is available for Nikon and Canon cameras only. I therefore designed an adapter to allow using the Canon 22mm version with the OM-D E-M1 and E-M1ii.

New version of the filter holder for the panasonic 7-14mm available

… long live the filter holder!

The mould for the Panasonic 7-14mm filter holder is dead. It did a good job but finally reached end of life. A new one would be too expensive.

I therefore uploaded the printing data to my Shapeways Shop. You may order a filter holder as 3D Selective Laser Sintered model directly from the shop. The filter holder isn’t as sturdy and doesn’t look that smug but it’s much cheaper.

Modified battery compartment lid for the OM-D E-M1 II

OM-D E-M1 II battery compartment lid: how to modify

Finally, the lid for the battery compartment is available as spare part. Time to modify one so the battery adapter cable may pass easily through the closed lid.

The modification is quite simple. Drill a 5 mm hole and cut the lid to get an oblong hole that protrudes towards the edge. It takes just a few minutes for a skilled worker.

Note: The camera isn’t splash-proof anymore when you use the modified lid!

LED ring now Breeze and DSLRBooth compatible!

After receiving several requests, I reworked my LED ring project. I simplified the circuitry and rewrote the software from scratch. The result is a LED ring that may be controlled by Breeze or DSLRBooth via USB.

The project is currently in prototype status.

In addition, I wrote a Windows application that can be integrated in most photo booth software packages. You may also control the LED ring straight through the virtual COM connection via USB.

The application reacts on command line parameters (like status screen file names) and sends the command configured for the calling parameter. The controller is able to display a set of predefined effects. Parameters can be used to tailor the effects in direction, speed or color.

Among the effects are a runnign rainbow, countdown status displays, blinking, solid color or swiping a couple of LEDs round the ring.
