Photo Booth LED Ring Service version 1.9.5 available!

LED Pfeil Arrow36DD
LED Arrow36DD

I extended the hardware available for the LED Strip Controller. The arrow may be mounted on the front panel of a photo booth or, as a variant, mounted sunken into the front panel. The arrow is lit by sideways mounted LEDs. This creates a smooth and evenly distributed light effect. The prototype has a length of 140mm from tail to tip, a width of 300 at the tail and 55mm across the arrow head. The depth is determined by the LED strip size and results in 17mm. A sunken mounted arrow protrudes 2mm above the front panel.

To control the LEDs of the arrow, I extended the LED Strip Controller firmware as well as the LED Ring Service application. One or two identical arrows may be lit at the same time.

The updated software may be downloaded from the LED Ring page.

New Finder Adapters available

Varimagni Adapter E-M1
Olympus angle finders and adapters.

I overhauled the adapters for angle finders and eyecups. They now have a better fit on the cameras.

In addition to the previously existing adapters, I added a new one that allows to mount the old OM Varimagni angle finder to OM-D E-M5 II, E-M5 III, E-M10 II und EM10 III.

Dear Search Engine Optimizer

… you might have noticed, that not all traffic that could reach my site actually reaches my site. That’s on purpose. I installed a Search Engine Deviation plug-in to leave some of the traffic for my dear competitors. Why I’m doing this? It’s no good sports to wipe out all competitors by aggressive optimization. I also don’t have enough time to handle all inquieries and orders I might get from an optimized website.

Did you ever hear of work-life-balance? I’m covering a nieche with my business and I have lots of fun doing so. Please accept that I like it to stay this way and refrain from sending me offers for search engine optimization. Even you found my site. That’s more than enough. Take a few minutes off and relax. Save the effort to contact me in vain. Save me the effort of deleting your message. See, it’s a win-win situation! Isn’t that great!


Photo Booth LED Ring Service version 1.9.4 available!

I improved automated recognition of controllers in the LED Ring Service. it’s even more stable now and supports also Controller.Nano.

The setup has been extended to allow selection of the controller type. This allows the setup to automatically detect controllers and to configure the LED Ring Service for a certain controller type. This avoides the need for manual configuration if updating the Service in a Controller.Nano environment.

The latest version is available for download on the LED Ring Service page.

New Controller versions available!


USB connectivity of the Controller Micro family has been improved. Controllers are now recognized by the operating system through a unique serial number. This fact stabilizes COM port assignment, even across software updates.

The new firmware can be downloaded on the LED Ring Service page.

Photo Booth LED Ring Service version 1.9.3 available!

I improved the LED Ring Service even further. It now detects controller ports automatically on start-up. Changes in COM port assignment that happen sometimes after Windows updates are recognized, resulting in a stable and continous operation.

In addition, I extended the configuration options to allow free running countdowns to be parameterized by the countdown duration sent by dslrBooth.

Adapter for the Olympus Varimagni angle finder

Varimagni Adapter E-M1
Angle finder adapters for the E-M1 family.

I got an Olympus Varimagni angle finder (the old OM system one, from the 70ies) to take measurements. I designed an adapter to mount it on the E-M1 family cameras.

Here you see the Olympus Varimagni (left) and the Olympus VA-1 (right), both with E-M1 family adapters.

More about the adapters on my Angle Finder page.

Photo Booth LED Ring Service version 1.9.2 available!

I extended the firmware of the LED Ring Controller Micro and LED Strip Controller Micro. A new function now allows to switch relais delayed. In addition to the immediately efective relais command, a delayed one may be specified. This allows to e.g. turn off effects after a given time without the need of sending a new command.

The LED Ring Service was adapted to support the new functionality.

Mobile Power for Olympus Cameras!

BLH-1, BLN-1 and BLS-5 Battery-Dummy

Hans Vollmer built an adapter that allows to power a camera from a power bank. The power bank has to implement the Quick Charge 3.0 or 2.0 standard in order to work with this solutuion.

Detailled information about power bank and camera compatibillity can be found on Hans Vollmer’s website and in a blog post by G. Wegner (both sites in German).
