Re: Pre modded servo boards for escs?

Hi Mike - please don't ever worry about questioning my testing - my understanding of electronics is rudimentary at best :D I did wonder whether my el-cheapo Neoteck DMM was correctly reading RMS voltage, so I tried the same test with one of my few surviving Das-Micro ESCs. There however I was defini...

Re: Pre modded servo boards for escs?

Having come quite late to the Antweight world, I missed out on the necessity for sourcing DIY ESCs made from servo boards. I was always curious about giving it a try but wasn't keen on the faff of balancing those tiny potentiometers. Hence, when I saw Mike's post about using the boards from digital ...

Re: Malenki-ESC open source Antweight ESC

Hi Mark,

I'd love to test one! I have one spare cPPM-equipped Orange RX 614, which could make for a very neat little combo.

Cheers,
Stuart

Re: decent antweight brushless

Worth checking the 'bargain bin' on HobbyKing website periodically. I recently picked up a few of these for less than four quid each and they run happily on 3S lipo via Afro 12A. This model went out of stock pretty quick but I've seen similar deals come and go so worth stocking up when you can. http...

Re: "What it says on the tin" N20s / Far from tacky tacho

Just to follow up - I ordered four 12V 1000rpm N20s from that eBay link that Luke recommended. Arrived within a week. Tested them with the tachometer last night and results were pretty conclusive - running on a freshly charged 6v NiMH battery, all four were within a couple of revs of 510 RPM. They a...

Re: Malenki-ESC open source Antweight ESC

This is VERY exciting (or should I say 'ochen volnuyushche') news, Mark! Support for cPPM would make life so much easier, especially if/when HK ever get the OrangeRx R614XN back in stock. Best of luck finishing it off.

Thanks Luke - will give some of those a try.

"What it says on the tin" N20s / Far from tacky tacho

Firstly a plea - has anyone found a *reliable* source of N20 motors on AliExpress that they're willing to share links to? Ideally motors that are at least vaguely close to the advertised speed... Secondly - a tip that might be useful to other newbies. Some months back, I ordered a few batches of wha...

Re: Pink servo??

Aha - apparently US #3 machine screw is 2.3mm across the threads, which is what I make the screw supplied with the servo. So I think Peter has hit the nail, so to speak.
Cheers. Now I just need to source some threaded rod that size....

Re: Pink servo??

Talking of pink servos, does anyone know the size of the thread in the middle of the splined arbor on the s306- ie the screw that holds the arm on? I’ve tried measuring it and seems to be around 2.2 or 2.3mm but hard to tell - and not even sure if it’s a standard pitch.

Re: Need a new esc

The DasMikros are great if you're lucky and get one of the ones that actually work but it seems rather hit and miss. Over the past year I've ordered three batches; First batch of three were fine and all three are still going strong Couple of months later, ordered three more, they sent me four :D but...

Re: Antweight World Series 58 - 29th June 2019

Well, I guess it's about time we let some of our ants experience the horrors of real combat... I'll enter separate teams for me and the boy (otherwise I'd never get a drive) but we'll try to keep it to 2-3 bots each. Had hoped for something more local but can't hold out any longer. Earliest train fr...

Spin(d)oza got new boots!

From my first batch of antweights, the definite runt of the litter was Spindoza. This was intended as a simple and durable push bot with big wheels and a front scoop that pivots freely around it's mid-point (so it always stays flush on the ground, even if the wheels are out of true and absorbs some ...

Re: Wiring N20 motor terminals

When I was starting out, I really struggled with those little N20 solder tags. However I'd read somewhere that it was a good idea to put a small capacitor across the motor to reduce sparking - that's when I discovered the wire on those tiny capacitors that ship with the Das Mikro ESCs will fit throu...

Re: Team Antiquarian new build diary

Thanks Mark. I had previously experimented with self-tapping screws but kept having problems with heads shearing off. Hence why I started experimenting with tapped holes. Really amazed how strong the joints are, even with just M2 size. Other pleasant surprise is that even where I've had to screw/uns...
