Champion! Thanks mfb!

Thanks! That helps. So a capacitor would smooth out any spikes to both operation of motors and readout of voltage, yes? Any cap size recommendations? And that would go parallel into the circuit before or after the voltage meter? Thanks!

Hi all! I'm working off of this schematic for a modded Nerf blaster (note: schematic not my own work). I am hoping to hook up a little lipo alarm (http://rcbitz.com.au/images/MiniLipoAlarm.jpg ) somewhere in there to display the voltage of my 1s lipo I'm using to power it. Question: Where...

Thanks for pointing me in the rght direction, MBG!

Hey all, Wanting to create an up/down counter that uses a photogate as a trigger, and a 12 segment LED bar graph to display the count. It will need to begin at full illumination, turning off one at a time on activation of the photogate. Will also need a reset switch, though I'm thinking a...

Thanks for walking me through that one, I just needed to be sure. Cheers!

Rudimentary physics is not my strong suit at the end of the day... or at the start, for that matter. If the flat magnet's pole is S, does that mean it will try and repel the S of the upright and attract the N, thus flipping it N side down and connecting the two? Sorry, I'm sure this is a very...

If I were to take 2 neodymium magnets, and lay one down on the table, and stand the other on its end on top of it (resembling an upside-down T), would they attract, repel, or be neutral? Two poles of the standing magnet against the single pole that is facing up... what would the outcome be? I...

People have fitted compressors to fill the tanks of air-blasters, so it's not an entirely new thing there. One of my faves, the Nerf Stampede, uses a motor and gears to prime a springed plunger tube and fire darts that way. What I'm trying has not been done before (to my knowledge), whilst a lot...

Hi mate, yes I've read extensively about coil guns, and whilst it'd be brilliant for my application, I'm more after the viability of retrofitting the existing plunger tubes and internal components of existing Nerf blasters. That also limits the amount of things I can cram into the shells of the...

Haha that sounds fun! Sorry I didn't make it entirely clear - I'm truly only interested in alternate means to produce fast linear motion in a plunger tube, in order to fire Nerf darts. The hope is to be able to retrofit most pre-existing blasters with this system and herald a new approach for...

Screw drives would be a powerful, yet slow alternative to priming. I'm attempting a spring-free design, so to increase rate of fire and reduce stress on otherwise flimsy plastic. Thanks for the suggestion though!

Thanks, think linear motors and actuators aren't going to cut it cause they move too slowly to make it worth my while. In my travels I discovered the wonders of neodymium, so I may change route altogether.. Thanks again!

Hello, first time poster, huge Nerf enthusiast. Hoping for some help with a concept, my grasp on electrical engineering is tenuous at best. I want to turn a Nerf plunger tube into a solenoid, by way of wrapping it in wire, and running a charge through it. I'd machine a free-floating...
