DIY SteadiCam Model 3.0

An experimental DIY steadicam project.
Model 3.0, inspired by merlin design.



For the gimbal i've use with Traxxas #5151 half shaft, and a ball bearing, soldered at the top of a metal pipe.
The camera is fixed on an ebay flash bracket stand, so it can slide and change the position.
There are a few connections for counterweights, i've use some metal plate and washers.
The example video is filmed very fast, this stabilizer can be more accurate, in my opinion, by a more carefull counterweight load, and with a more experienced operator.

an AVR Atmega 7-segment commond anode / cathode display library

Updated to version 0x03

A seven-segment display (SSD), or seven-segment indicator, is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays.



This is a simple seven segment library that let you display char / numbers, or any sequance you need to multiple display.
It runs both on common anode, and common cathode display.
I've used a lookup table to convert ascii table. Also a function to display any sequence you want is available.


Below you can find sample schematics to run multiple diasplay.
The full transistor version let you run disaply at your desired voltage.
