Undertable wrote:Hello again,
after trying out my Merlin-mod for a while I did some further small changes* and finished now.
- covered bullseye levels rearside (sun shined through at edge areas and caused malfunction)
- moved the RRS-rail 10mm. Scale starts with zero in the upper pivot axis now and rail is effectively 10mm longer.
- althogh I didnÂ´t use it so far I insulated wireless trigger`s flash socket and connected it again (caused some trouble with bluetooth connection because of the conductive housing)
- additional LED for "wireless trigger ON"
So this is the final version:
