Re: MG90 servos

Yes here is a diagram from my book Small Combat Robots. https://www.amazon.co.uk/dp/B07NJ9116Z (Another shameless plug) https://1u4cxg.db.files.1drv.com/y4maw1EbdKHVaT5qeV0YXrbhLsdsORkEElfyVb2B8JQLmxSvlo2_Z928_53NfsQxqbAtPjRPP5duAymLbQkCg3WFjdv2zcrXympDwm3qe2DI26SBR70OlQpIvgzsDg5gGeJIWRVN6tMmJiEWo6B...

Re: MG90 servos

I build my own controllers with the receiver mounted on the controller board. The servo plug is also on the controller board so it shares the same 5 v 1.5 A regulator but is not powered through the receiver.

Re: MG90 servos

Although some receivers can run off the full 2S supply I prefer to run it from the 5 V regulated supply.
Because the 2S supply is running all the motors there is more chances that it is noisier and therefore more likely to interfere with the receiver.

Re: Peter Wallers Robot Ramblings

It is a 2 layer circuit board with components just on one side. I have a very old copy of Protel Client98 (1998 vintage) that I have to run on an old Vista machine because it won't run on Windows 10. I am just trying a later version of Protel DXP which does seem to run on W10 so I will probably migr...

The PCB's have arrived that's just 5 days from uploading the file. Here it is next to the lemon receiver. https://0u7hua.db.files.1drv.com/y4meR74pleqybYrbNx_60T12xmg2grua2E9JxKnIoU71_1rl0_s_FtDDGRGmGn_9zv5gOtAI5Zm-Qh0YhCyJyKbq8az3tw-LVdeewz4ocTeaBwYAVDTL237EG0f7IFd02aXFnE9HBjlmFTg0nlzdn2pN8WyTjlydS...

Re: Peter Wallers Robot Ramblings

One of the biggest problems I find as I get older is starting more and more projects without necessarily finishing any. Someone on here mentioned the RZ7899 motor driver that looks really good. It is similar in spec to the DRV8872 I use in my latest design but doesn't have the pad under the IC that ...

Re: Peter Wallers Robot Ramblings

To be honest I am not sure my physics is a bit dodgy in this area.
I thought it was about as quick but that may be due to the springs being stronger than the bands I was using.

Re: Pneumatic antweight.

I think that about covers it but there are various switches and rams. The switches can be electrically operated or mechanically. The former need some sort of switched output from the controller and the mechanical ones need a small servo to operate them. You need to make sure that in the off position...

Re: The smart ant's and flea's

That would be a shame but your education comes first and you can always return to robots after if you are still interested.
You never know your uni might have a robotics club.

Re: Pre modded servo boards for escs?

You don't need to apologize it is all good information you have been posting.
If people aren't interested they don't have to read it but I am sure it will be useful to those contemplating using servo boards. :D
