That really looks great! Nice and smooth. Did you build your own servo tester or buy?

I'm still working on ideas on how to incorporate a linear actuator into the arm of Magnus.

I bought the servo tester off ebay for 5 bucks.

check out servo BUDDY in the servo magazine or on the internet search,simple circuit just 2 555 timers and few parts ,good for checking servo's

I like that Bret. I too thought you had a large scale B9.

Found a 555 circuit. I'm going to build it tonight if I have time.

Bret have you tried placing the rubber arms over the servos to make sure they can flex it?

circuits for me is much much fun to design and build,can buy them but not as much fun as building it your self ,like in baking,witch i was baker for awhile,i would make a cake from scratch then buy one still do much baking at home with the best in baking equipment

All this mechanical stuff is a good challenge for the mind but kind of a drag too...especially the endless sanding....I am learning a lot though. There are so many talented people on this forum! So many good ideas!

But, I have my most fun building circuits

if you or anyone else stuck or need a design on a circuit ,my service is FREE i first use a proto type bread board,fully test it,then build it and then fully test it again

same again with building arms,its pretty easy to come up with the design ,but witout fully test it before you put it together ,it saves alot of rework some of us also overkill ,witch meens a very large battery and puts much stress on motors or short run time when i design like most robot companies do it,make it very efficiency,low current sensors and boards ,motors and servo;s running at half the rated power,LDO regulators and light batteries,can almost run a full day or more if designed right
