Hi there,

this is Sascha (Sasha Gribb is my nick name) from Germany. I am founder of the no-budget short-films team called
RANDOM FRIENDS. I am the technician in this team It is not my profession, but my hobby.

The projects listed in the subject are on my to-do-list. Nothing has really been brought to an end. My problem
is: the factory is in my parents garden and all my work depends on weather conditions.

However the RC-remote head, the Crane, the cablecam have come very close to working constructions. Unfortunatelly this hobby is really expensive and do have to invent everything for new and to test all alternatives. That is why I havent been able to find affordable basis for a crane (do you know the word crossbar? Traverse? You will see on my pictures what I mean).

I took the LEBCCAM as role model for my cablecam and mixed its construction with own ideas. As a result I decided to take 2 cables (=4). In my opinion one has advantages in weight problems and stability. At the beginning I thougt I might
use with this "invention" almost invisible but durable fishing line (up to 100kg). The stability is not the Problem: it is the tool that tightens the wire.... as it damaged the wire At least I ordered steel cable 4mm, 200m.

The vehicle (how do you call it? Trolley? Rig?) consists of two T-Bars from a Tripod for DJs. It is very light, black and has
everything I need - including the holes for some axis. It is quite handy thining about mobility.... it is a multi purpose thing. T-Bar, Cablecam-Vehicle or something else! Very handy!




The next picture shows the traverse (decotruss) what I expect to work as cameracrane. Hopefully. The 5cm (2mm) aluminium pipes did not work. And you can see the T-Bar on the tripod.




What about physics? I do not know how to install the cables. Okay, if you have big trees or something like that at the set, its nice. But if there was nothing? Ladders? How much weight does one need to get the cable as tightened as possible? I found out that it does not matter how long the calbe is (newton), what I have thought before. In addition I
found out that it is quite impossible to get the cable horizontal... it is about millions of Nm to do that.

While testing I took a big tree at the one side and a ladder on the other side. A car battery (20kg) was put on the latters ground plate to hold it at its place.


Next I plan to test the gyrostabilized remotehead for the cablecam. Last year it was tested as gyrostabilized steadycam, but that didnt work as the sensor detects gravity.... and footsteps make the sensor getting crazy.
The sensor usually works on RC-submarines to get them stabilized on ther length-axis. So I expect the sensor to work
on a cablecam as differences in gravity are very low (I hope).

If it will work on the crane, too? Tested it, holding the remote head in my hands while turning the complete construction around (one axis). That worked really smooth and fine.
