Re: PLANNED OUTAGE - Weds 1st April 6pm onwards

Good job, it's working really well.

One thing I can suggest, is can we have https enabled by default automatically (e.g. with a redirect?)

Seems very fast.

Thanks

Re: Team Astro Build Log (Cheese bots)

If the RX is fine with 10 volts, then the wiring is easy. Just make up two "Y" cables and wire the negative and positive to the rx negative and positive and the esc negative and positive. In receivers with traditional "servo plug" connectors, all the positive and negative pins ar...

Re: Team Astro Build Log (Cheese bots)

"Opto" means the ESC has an opto-isolator inside (basically a LED+photodiode in the same package, the signal is transmitted optically), so the two wires coming from the RX are totally electrically isolated from the battery power coming in. This is useful, e.g. for fixed-wing aircraft which...

Re: ESC with built-in receiver - interesting?

Further to recent updates, I've made a video:

I've got it to do telemetry. It gives the battery voltage and microcontroller temperature right now.

There is only one in existence, its right channel can't reverse and the firmware isn't 100% working... :)

They will be ready when they're ready.

Re: Parts trade

I would be happy to trade, but I don't think we're allowed to send Lipos through the post. Royal mail have a restriction on Lipo batteries in particular. We can send them by some other method, but it can get expensive quickly. --- I wouldn't want my postie to be safe from CV, only to get ignited by ...

If that (huge vert) gets into a competition, I think it will pick up "best engineered" very, very easily!

If you look carefully in the photograph, you can see the bodge wire. It is 3mm long. Oops :)

Re: ESC with built-in receiver - interesting?

I have no idea when/if it will get into production.

I am currently stuck at home, like everyone else. I'm tweaking the firmware. That is quite interesting, I have learnt how to write avr assembly language :)

I hope the Antweight robot scene will restart when it is possible!
