In one of your posts where you have shown the powering method of your phoenix, you mentioned that you used two 9v batteries in parallel for the logic circuitry.
Can you please explain me how did you connect the batteries in parallel? Did you connect any diodes to each battery ensuring that a battery at higher potential does not charge the battery at the lower potential? or you just simple connected the parallel configuration to the VL?
I am intending to attach 2-9v 200mA Nimh batteries for my logic, since it powers SSC32, BlueSmirf and a couple of LEDS so a single 9v battery is not sufficient.
It works fine just connecting them in parallel. Just make sure they both are equaly charged. But NEVER try that on a LiPo.
Another solution for powering the logic is to connect the LiPo you are using for the servos directly to the VL. No need for the extra 9v battery. I’ve never tried it for Phoenix but it worked fine for Felix though.
The walking height does not affect the load on the servos as long as the tars(foot) has the same horisontal distance from the femur joint. Why are you asking?
Thanks for the response. I’m working on a “Phoenix hybrid”. 8)
I noticed that most people have their phoenix walking low to the ground, the tibia joint being higher than the femur. I’m contemplating using a higher base position than is typical. I’m glad to hear that it will not increase load if done correctly. I will keep in mind your point about the horizontal distance.
If you have any other nuggets of wisdom to share I’m all years. You grok this stuff like no one else one Earth.
I’ve posted some stuff about the GP player in my T-Hex thread. But since I’m using my good old Phoenix for a little demo for the Lynxmotion forum I thought I should bring this old thread back to life again…
Here is a short workshop video where I demonstrate the GP player with adjustable speed and direction. Sorry about all the mess…
Thanks for watching!
(ehm… Jim, doesn’t this thread deserve to be a sticky… )
Like I said on the GP-player topic. Great work! It is really cool to adjust the speed and even rewind it! Should be a really cool feature to add in the new 2.1 release 8)
Thanks! I’m glad you are going to put this in the next release. And with the PO bug soon to be solved everyone with a Phoenix can use the same sequences! 8)
Yep, I think it will be great to add some of that functionality to the next release. May play with that today… Now if only I had some sequences for a 3 DOF T-HEX. Will try to cobble something… But I am not great at this . For now I will probably simply adapt one or two of Zentas phoenix ones to it and see what it does…
Shouldn’t be to hard to make a simple sequences for your 3DOF T-Hex. I don’t have one so its a bit hard to help you out. Some of the sequences I made for Phoenix might work for testing though. Good luck and have fun!
