Team Pushover: Build Log

[Retroman]

So, after almost giving up last year, here we are. I'm going to create just the one build log rather than keep cluttering up the forum.

I've just finished up a rebuild of the AW Pullover, chall9enging myself to build as neatly as possible. Now, having finished shrink wrapping all the joints, I plug the battery in, insert link/fuse, aaaand, the fuse blew.

I think I'm already way underspecced on the fuse anyway, but I obviously have a short somewhere... great...

Specs:
NanoTwo V3
Vex29 for grabber
2s 20c 3500mah (I think) LiPo
5A fuse
2 x 1000rpm (alleged) n20's for drive
1 x 60rpm high torque n20 for grabber
25mm tough hub wheels
Main body is recycled high impact plastic, grabber arm is from an offcut (polycarb version as spare) and bottom/rear panel are 1.5mm polycarbonate

I digress, first pic of the new log!

That is so neat, much better than mine at the moment, nice work!

[Retroman]

If it worked I'd be happy... it's a neat paperweight right Now, I need to remove all the heat shrink and go through every connection and double check polarity etc..., probably even need to de-shrink the Vex29 and make sure I haven't moved a couple wires or something...

So as function over form, everyone's is better than mine

[Retroman]

Well... I, erm... don't know how to say this... I appear to have got the + and - the wrong way round in my soldering frenzy...

So I'll swap them back to where they should be and cross everything that I haven't cooked the NanoTwo...

And don't worry, I've called myself enough names for everyone

[Ocracoke]

Oops. I've done that before with a FeatherTwo in the past. Not fun I'll say.

[Retroman]

Well... no magic smoke at least, so when I get chance to swap it all about it should hopefully still work.

Then all that's left is to take Wej from broken and battered to fully functional experiment... watch this space!

Looking good mate! Fingers crossed it’s okay! I have been trying to design a new Ant on CAD to have it 3D printed but every time I say to myself “it’s finished” I think “ohh nooo I need to do this or that!” So it’s a bit of a nightmare! Haha but hopefully I’ll get something finished soon and printed out! Pull Over deserves a better Duos partner haha! So I’ll get cracking again today!

That is some sweeeet wiring. I can relate to you getting distracted by laying everything out to look nice, I'm pretty sure I nearly did the same because the black wire either gave a nice colour contrast or was the right size to fit in neatly. :P

Hope the fuse saved the NanoTwo and look forward to watching the rest of the build!

[Retroman]

Ooh what's the new one Wolf? Excited to see it, and tbf, even though I couldnt grab, we did ok

Yeah I think what's happened is I've swapped the fuse/link (luse? Flink?) To the opposite side to save a few g of wire, I'm almost certain I flipped it to put the battery connector to the middle again... like a dolt...

Thanks for all the comments too guys! Keeping it small and neat has been a nightmare, HAVS stage 1 and 50%ish dexterity in 4 fingers over winter makes things 10x more fiddly.

[Ocracoke]

If there isn't any smoke or any heat when the NanoTwo is on, I'd say you were OK. I've cooked my NanoTwo by having a servo plugged in the wrong way (Ikari) so bleh. With the fuse, I'd guess you'd be OK, fingers crossed.

@Bad Wolf: looking forwards to seeing your new one!

[Retroman]

Yeah we had no smoke, and the fuse went instantly so no time to get hot, I should have the time spare tomorrow or Monday to find out... I wonder if they're in stock... you know, just in case.

[Ocracoke]

From a conversation I overheard at Ant Freeze 6, no. The problem is that the receiver used on the NanoTwo is not in stock at the moment. If you contact Rory on here, he might be able to shed some light on that.

A quote from Team Nuts's facebook.

The NanoTwo V3s were forcibly discontinued when the small OrangeRX receivers which they were based around disappeared. Many other DSMX/2 RXs are also being discontinued at the moment, so to avoid all that, the NanoTwo LT is essentially a NanoTwo V2 (which was a cheaper and more reliable design than the V3) with servo leads attached allowing you to use your RX of choice. This should work well for many BBB teams looking to upgrade their kits.

They will be appearing for sale soon. Since the bulk of the manufacturing has been done already, stock levels should also be more reliable now.

[Retroman]

Boom! Cheers James, I'm not on Facebook anymore so I hadn't seen That, good to know... and hopefully I don't need one quite yet anyway... valuable to know though.

Ang while I'm on, quick teaser for Wej, a polycarb front hinge flipper with a target flip of 350g at the top most extremity, if I can get my set up to work fast enough I *should* be able to launch another ant pretty effectively, it's purely experimental at this stage but looking reasonably positive, pictures as soon as it's worth looking at!

[James Williams]

I'm not on Facebook anymore

Don't blame you, I'm not on there either. I only saw that by chance as I was looking for info about the next BBB event. Even if you don't need one yet I'd still grab one as soon as you can, each batch sells out within hours & it's usually several months between batches. If I remember I'll leave a message on here next time I notice they're available.
