radio-controlled

I managed to get the little Jansen style walker up and running on radio control. Probably overloaded the central supports with a huge 5 cell AA Nicad pack, and 7 channel Rx... and indeed it did "realign" the gears, which caused a bit of skipping. However the point of the exercise was to see if it would take a radio signal, and it does. If it takes a radio signal it means I wan swap in an Arduino and use the PWM channel.


On another tack I nipped down to #buildbrighton last  Thursday and with Adam's help disassembled a Dalek voice changer helmet, and stuck the sound circuitry into the head of our "real" Dalek.
It works after a fashion, and flashes the dome lights too.
Once I've done the hard work building the neck section, I'll strat wiring stuff up properly.

ready for action

Just put the finishing touches to Meathammer
The whole setup works quite well.. I'm off to modelworld to run it through it's paces a couple of times.
The weak bits look to be the drive shafts, which I'd like to bulk up to at least 20mm and have some better bearnings for.
The battery packs are also a bit weedy, but we'll see how they last, and may invest in a few high output packs.
Of course it could also really do with running the 4QD 35's or 60's instead of the electronise speedies.. but we'll see how it performs and make amends.
Since I took this phot I've added a hinged scoop, so we can get under other feathers... it's a popular design in the states, should work over here.
I only need to wire in an LED to show power and then we are ok to roll.

The weakness of machines

All of the robots I have built have failed in fights, and usually at the axles/wheels, it's like a running joke.
So why should it be any different with this featherweight?
Meathammer was designed back in 2005/06 when using 4 drill motors was a bit of a novelty... it was made more novel still by mounting the epicyclic gear cages directly to the chassis, which unfortunately sends all the drive shocks back through the gearbox.

The original version ran for a number of fights at modelworld 2006? and even won some, especially the sumo, which favoured its very low profile.
I've just rebuilt the gearboxes with all metal gears, and tested it, and it seems it should last for at least one fight… but as I put it in the car after testing, I noted one of the wheels had nearly fallen off. Mark that bolt for Lockthreading!

All this got me thinking if I could make something less likely to lose a wheel, break a gearbox etc
I have a huge pile of bits and bobs that were destined for heavier machi…

Fake Plastic Trees...

So, for a bit of light relief I bought a few of Justin's LED Christmas tree kits.


I think the original idea was to have a relatively easy kit to put together on Saturday workshops in the run up to Christmas, but they seem to have become quite popular with all manner of folk.


Anyway, the kit is based around a couple of well made pcbs, a bag full of components, and the simple instruction that +ve is UP.
It took about 10 mins to solder all the bits together, and with a huge amount of satisfaction over the end result.

The Build Brighton Christmas workshops will be running each Saturday from 30th November to 21st December from 10am – 2pm. Entrance is completely free. Kits are priced between £2 and £5.
