Re: NST

This new unit does still use an RC switch for the low current side (which I have found to be very reliable).

The board has an opto-issolator, its just building a bit of failure protection into the device.

Hi Sam

Just out of interest, no reason in particular but how high is NST's bar from the floor???

Don't believe him Sam

Re: NST

my guess is the same height you don't want it to be :wink:

Re: NST

This is a random question but how heavy is the blade? And what kind of rpm are you hoping for with it?

Re: NST

and whats the ground clearance at the back? and where is the link located? :P

Re: NST

Should one of us build an X-Wing featherweight for navigating the channel to the exhaust port then?

Re: NST

No worries Jamie, I liked the posts

Progress has been slow, but alot closer now to completing the Dewalt motor upgrade V2.

The brushes weren't supported to well in the original version causing their edges to chip slightly when the robot took impacts. Alot more effort this time to design something which secure the brushes properly. Its been a lot more challenging than I first expected. Was toying with using the stock brush holders for ages then decided to bite the bullet and machine my own in aluminium.

Re: NST

What will this do to the power of the bar? You were running the Dewalt last year so is this simply to make it even more reliable and eeek that little bit more from the motor without actually changing it?

[sam_smith]

Re: NST

That exactly it. Just refining the current setup. In theory it should be more reliable and preserve 'new' motor performance for longer.

I have taken the decision not to make the bar more powerful this year as it'll near enough guarantee that the machine will launch itself out of the arena during the champs.

If I wanted to up the power of the bar, this could easily be done by going 8 cell on the dewalt, or putting the brushless system back in and refining it.

Don't worry, the new machine, 'Shard' will be more powerful

Re: NST

Will you reveal any details about it? Horizontal, Vertical, Brushless? Its not hard to image something more dangerous than NST but something that will stay in the arena...?

Re: NST

motor mods look really nice sam! I cant see a machine that would really beat NST so i think you have a good chance at defending the title. Good luck... except if you have to fight Predator lol
