Re: Mike's M3 Lee #12 Little Build Things

Looks like on the real ones, the hinges fold into each other, so the bolts don't clash.

Could it be the button heads which are hitting each other ? Could you swap them for CSK instead ?

Re: 75mm Gun Stabilisation

Jeff, they tend to use brushless motors mounted at the axes of rotation, which would entail a complete redesign of the gun mount.

The assumption is that this gun will use a servo for elevation, so this system should be a drop in.

Re: 75mm Gun Stabilisation

:lol: :lol: :lol: I've not checked the balance of the system but the Mark IV Male has quite a short barrel and quite a lot of gubbins at the back, so it won't be any where near as bad as the Chietain with a metre of barrel hanging over the pivot point. It is a 6DOF board but I'm only using one of th...

Re: 75mm Gun Stabilisation

No, there are no programmed delays in the code. I haven't really delved into it too deep yet, I wanted to the basic premise working first. Are you going to try and control the recoil with timing, rather than relying on the switches ? I wonder if it needs an opto or hall effect transducer to detect t...

75mm Gun Stabilisation

Since the M3 was announced, I knew I wanted to build a gun stabilisation system for the 75mm. This is the first attempt. It's pretty crude but works as a proof of concept. 75mm Stab.jpg https://youtu.be/mqdcfCmrEyI I need to speed up the response, but get into stability issues with the current syste...
