Re: Das Mikro - £12 dual channel speed controller with mixing

How is the receiver powered? If it's powered via the speed controller then the addition of a servo may have overloaded the voltage regulator (aka BEC) in the speed controller. If you've damaged the voltage regulator it may affect operation of the speed controller and will almost certainly affect the...

Re: University of Greenwich Open day - Saturday July 1st

I'm sure we can make this work :) One thing to bear in mind for spectators is that Ants are very small! A big screen showing the action would be really useful otherwise only a very small number of people can actually see what's going on. From a health & safety point of view we need to segregate spec...

Re: Help/Build diary for/of my first antweight.

If you fix polycarb at two ends at different angles it will naturally form a curve :) Take a look at Pants or Make-A-Bot to see how it works. It won't break even if you form it into a sharp bend, so a gentle curve is no problem.

Re: My first ant was not a success: Onto the second!

You should be OK tapping 1.5mm at M2, the pitch is only 0.4mm so you'd get nearly 4 full turns of engagement. Alternatively small self-tappers should hold. You could locally thicken the polycarbonate in the areas of the holes, just stick an extra layer on - it doesn't have to do much so doesn't need...

Re: Seismic Robot Build Diary [First Time Builder]

If the polycarbonate is thick enough you can tap it and use M2 or M2.5 machine screws. 1mm is a bit thin to tap but small self-tapping screws hold pretty well.

Re: Seismic Robot Build Diary [First Time Builder]

You could use 3mm polycarbonate for the base, but it will almost certainly be too heavy if you make the entire robot from 3mm. Most people tend to use 1mm or 1.5mm as it is fairly easy to bend and a reasonable compromise between weight and strength. Most people use Pololu (or equivalent) 10mm gear m...

Re: PCB Manufacture

With very small boards like this you may often get a few extra, but it will depend on how they fill the panels when they run the boards. A good deal if you get the offer and can make use of it though!

Re: Help/Build diary for/of my first antweight.

What are the dimensions? Without some dimensions you could have any arbitrary answer but the angles wouldn't necessarily be what you wanted!

Re: Help/Build diary for/of my first antweight.

You can figure out the movement your linkage will give using some fairly basic geometry, remember that a servo doesn't move much more than 90 degrees without some tweaking. Figuring out the speed can be a bit more complex as it's not always constant. This tool http://blog.rectorsquid.com/linkage-mec...

Re: Help/Build diary for/of my first antweight.

First of all, welcome to the forum! Rory's kit won't work with DSMX transmitters, only DSM2.This is down to the receiver module that he uses. You can get the speed controller board without the receiver and use your own to avoid compatibility problems but it will probably be bigger and heavier. The T...
