I'm looking to build a reliable featherweight but don't know where to start

[Eventorizon]

I'd suggest generic 12V LED strip or a Panel Mount 12V LED (you can find both at Maplins- http://goo.gl/dI4j03, or on Ebay- http://goo.gl/Xg6c6V http://goo.gl/yujLSJ ) - They will be slightly dim as they will be under volted but with a good long run of LED strip you can't really go wrong.

Agree with Alex, stick a 12V one in, I've used them on a 7.2V pack and they work fine.

Hi,

My design's changed slightly, I plan to utilise a grabber/crusher in the vein of the S5 incarnation of Suicidal Tendencies (where the crusher and lifter work as one)

I plan to utilise a linear actuator which would pull the two parts together, however I'm unsure what ESC is best for the actuator.
I plan to utilise this linear actuator:

Hi,

I built a test bed using the Extreme Robots how to make a featherweight video, originally the electronics were to the video’s specs, I’m currently adding the fuse holder, and LED so it complies to the build rules. At present I’m using the batteries that came with the drills (https://www.diy.com/departments/b-q-.../173942_BQ.prd), using the LED wizard that overkill suggested, I found the LED I chose (a 12v maplin chrome bezel yellow led) needed a 560ohm resistor.

It may sound like a daft question, but if I was supplying the source voltage of the battery (12v) would the resistor be needed?

Many thanks,

Sam

I suspect you'd be OK if the LED accepts 12v with a matching voltage battery though the only LEDs I've ever used have resistors wired in anyway apart from the one I hastily put together in Manchester.

Hi,

Having soldered the resistor in, I found the light to be fairly dull. As it turns out, the LED I bought had a resistor built in (so the separate resistor wasn’t needed at all), nonetheless the LED is now in the wiring loom. I’ll think I’ll put this in a build diary soon.

Many thanks,

Sam

Had a good read of this thread, picked up some good ideas for myself, keep up the good work
