Cool model !

 

I'm looking at your turret, as I just recently made one myself and I am sort of flabbergasted by the compact size of your mechanism...

From the picture it looks like you are running a linear actuator trough the center of a black gear.... and I'm like ... wut ? ... how ?

[CharlesD]

Indeed a linear actuator, i got the idea after seeing sariels latest video. It's not perfect yet, here is the file

Thanks !

I see now it's the small linear actuator running trough the small turntable.

I used a large one going trough a large turntable and only got one motor for pan and tilt so I had to incorporate a gear switching mechanism, so it got rather bulky.

I like the elegance of yours.

It features a laser guided pneumatic missile launcher.

Nice, does it fire actual missiles?

[Permo]

Yes it does, very accurate at 2,5 to 3mtr distance... it can shoot over 10mtr distance.

The barrel is a drinking straw that happens to fit the 4L tan axle with round bit very tight.

I expected it to never come out again, could not blow it out myself... but with 50psi from the well pumped airtank it shot it all across my house into the curtains in the other room.

I was blown away by the amount of punch this compact gun packs.

 

Here's a test shot at aprox half power of the system; https://bricksafe.com/files/Permo/the-black-project/Shot.mp4

The laser and air release servo share the same control, so first I aim the laser, then pump the tank... and fire the shot. I get 9 out of 10 direct hits with this.

Very compact;

Very cool idea!

[Permo]

Thanks !

 

Don't know if they still sell these straws as they are plastic... I got mine from "de Appie" years ago... it's just a perfect fit.

I found something under the dust and decided to give it another go.

Made some changes and improvements and it drives quite well, i have added pictures and the design to my Bricksafe

I can make a video if anyone is interested.
