Re: Soldering irons?

I'm also using an elderly Antex x25 (sadly with the clunky old pvc flex rather than supple modern silicone) and would also give the thumbs up, though life became much easier after switching to a 1mm tip. Now if someone can recommend a really GOOD helping-hands gizmo, that would be great. I've tried ...

Re: Team Antiquarian build diary

Current work in progress is a flipper called (for reasons that will become clear in due course) "Project Box Bot". Space for innards is even more constrained than usual so decided to see what I could do to slim down the Redcon 4CH DSM2 receiver + DasMicro 2S6A ESC combination. With some trepidation,...

Re: The adventures of an antweight robot building nerb

As you may have already noticed, there's a basic wiring diagram (annotated photograph) on the Banggood website's product page. For the servo leads, it doesn't help that the wire colour combinations vary from one pack to the next - but should be either Brown/Red/Orange or Black/Red/White. With the mo...

Re: Team Antiquarian build diary

Actually managed to get quite a lot of time in the workshop this weekend (and with TMS on the radio too - sheer bliss) so I've been experimenting with alternative ways to build using polycarbonate sheets. I have some large sheets of the stuff and various off-cuts lying around, left over from DIY sec...

Re: Team Antiquarian build diary

On reflection, decided that my "Flippin' Ugly" experiment (see above) might be salvageable, if I could lower the aspect ratio and move the wheels back a bit. So... out with the tin-snips and on with the face lift. Basically chopped off the top third of the wedge; https://i.imgur.com/NtVtvuj.jpg Ten ...

Re: Team Antiquarian build diary

Having spent a few weeks mucking about with ideas and test-beds, I decided it was time I got at least one of the half-dozen antweights I hope to build before Christmas finished. So... without further ado, I give you... " Shove-All " (this is my first attempt at embedding imgur image-links, so finger...

Re: Team Antiquarian build diary

BTW, this was my very first (and very heavy) attempt at at robot - the Proof of Concept, or 'PoC-Bot'. Smiley face was added just so driver knows which end is forwards. Eventually he may gain a lifter/flipper arm one end, a bucket the other and a Pi or Arduino board in the middle, before being rebor...

Re: Team Antiquarian build diary

BTW, In the spirit of 'keep it simple, keep it safe', here's the hi-tech flipper-return mechanism - just a length of 'powergum' from my sea-fishing goodies box: FlippinUgly-4.JPG FlippinUgly-5.JPG Having messed about with Flippin' Ugly, several lessons were learnt: 1) The wheels need to be further b...

Re: Team Antiquarian build diary

Finally time to finish off my first prototype Antweight. The big brass hinge had to go - simply too heavy and it was in the way. Instead, I made the top flap with little tabs that I drilled and bent over, then attached to the main body with M3 bolts, using plastic-insert nuts so I could keep the hin...

Re: Team Antiquarian build diary

After playing around with trying to fit the various components into a small space, I decided life would be easier if all the cables were emerging from the same end if the ESC (well, I see from pictures that the wires on the Nano do, so it must be a sensible design feature!) Having abandoned the Mole...

Re: Team Antiquarian build diary

So the Molex KK396-type pcb headers arrived and I found time over the weekend to solder one on to a DasMicro board, just as an experiment. Turned out to be pretty easy, even with my terrible soldering technique. Trick was to get plenty of solder onto the surface pads and the header pins separately f...

Re: Team Antiquarian build diary

Thanks for those comments. - very helpful. Got me thinking about more compact ways of making the motor connections (you're quite right - even on short leads, the JST XH in-line connector pairs are a bit long and may cause problems fitting into an antweight). Next option I plan to experiment with is ...

Team Antiquarian build diary

Hello everyone. Here begins yet another newb's build diary. Apologies if it's only updated erratically - always tricky to find time! Thanks for reading, Stuart ----------------------------- As a bit of backgound, I want to make around 4-6 antweights plus an arena for my son's 8th birthday/Christmas ...
