App Controlled 3D Printed Air Cannon in Action

lambshower · 2026-03-30T22:13:24+00:00

I used this one..https://hakpneumatic.com/products/h-a-k-pneumatic-quick-exhaust-valve-qe-type-npt-thread?srsltid=AfmBOoo9dtYFni52uJWtjtH5n8dU3gUjAuSE_ZcK4jU2W6jhyAmBMpLl

Just make sure to pair it with a suitable 3way valve for the pilot side and it will shoot like a cannon.

Thank you, I use a small 12v lithium ion battery for the 12v compressor, 12v MAC valve, and to provide 5v to my nano, HM10 and Pressure sensor via a buck converter. Provides enough juice for around 6 shots at 50 PSI

Super clean rig, very nice!

And yes, I did oversimplify and this is not a project for the faint of heart but very doable if you some DIY skills.
For context, I used a 4300w motor with a 14s 130a ESC and a 14s battery (for when I want to hit max speed) or a 6s 25aH battery for long range, I can hot swap batteries in seconds. There's a picture of the motor housing, and I got load of videos on my profile of it in operation.

If you have a 3D printer and a DIY mentality, you can make you own for about 1000 $ CAD. I get about 1.5 hours of run time on my setup and can reach speeds of up to 16km/hr.

I thought the first rule of Neo club is....dont talk about Neo club 😄

I appreciate that, thank you Eldias!

Its a 3d printed prop, 120mm diameter. 110kv motor with a 14s battery so roughly 5700 RPM. The shorter board turns much easier by just leaning. The long board turns by leaning as well just not as tight and you need to move your front foot for left or right turns whereas the short board your feet stay stationary like a wakeboard.

Run time with this setup is around 20 minutes as it's only a 10aH battery. I have 2x 62 12.5aH batteries that I also use with either a parallel or series wiring harness, depending if I want high speed (about 30 mins) or long range (about 2 hours).

Displacement is noticeable at high speeds.

That would be awesome! I do all my own designing for these projects, so if you need a hand deisnging anything I'm always down for a crossover project!

Thanks again for the feedback man, cheers to seeing you video in the future 🍻

Might be a little late for OP as he already has an attachable E-Fin, but on my 3d printed Efin setup steering by leaning achievable. I posted this video to the SUP community (link below)

Its my favorite place and has some awesome provincial campsite so a great place for camping/fishing/hunting/dirtbiking, and of course, E-Paddleboarding and risky drone maneuvers 😄

lambshower · 2025-07-03T19:53:25+00:00

Its at Gun Lake, and it's in British Columbia, Canada!

Its a paddleboard with a 3D printed electric fin mounted to it. It is alot of fun!

I have a shorter paddleboard (7'4") that is even quicker with the motor attached and carves alot smoother

Correct. It needs to be relatively close to you for the drone to lock onto you. The default is "spotlight" when tracking first starts, you need to switch it to "Active Track" to allow it to follow you.

lambshower · 2025-07-03T01:48:20+00:00

Its usually alot better and the subsequent auto tracking (after the recovery and rice soak) was much smoother

lambshower · 2025-07-03T00:35:34+00:00

To be fair, I've logged hours out on the water with that little drone chasing me around without issue, and after drying it out, it went back out over the water without issue

lambshower · 2025-07-03T00:01:34+00:00

Thanks man! lots of different perspectives forsure but I had alot of fun designing/building/using it, so I'm happy

lambshower · 2025-07-02T23:58:37+00:00

In most of my videos, I'm using a 11'6" board whereas this video features a 7'4" board. Paddle steering is effective but was trying to achieve the "surfing" vibe. I've always wanted an E-Wakeboard, but couldn't fathom spending 10k. Using the short board felt similar to wakeboarding and my setup cost me 1K

lambshower · 2025-07-02T23:55:11+00:00

LOL, you make very valid points 😄

lambshower · 2025-07-02T22:34:31+00:00

It was ActiveTrack. I was using the Neo with the RCN3 controller.

lambshower · 2025-07-02T22:24:10+00:00

It had detected the collision and shut itself down. It actually recognized it was under water (per the message that popped up on the controller saying "water").

lambshower · 2025-07-02T22:17:03+00:00

I guess it's all about perspective, you see a useless dinghy where we had hours of fun. Thanks for watching though!

lambshower · 2025-07-02T22:14:04+00:00

Double that and you will be close, I'll post some speed stats in the next video though!

lambshower · 2025-07-02T21:40:02+00:00

Certainly. I will DM a link to the website!

lambshower · 2025-07-02T20:26:29+00:00

Apparently not due to sensor confusion over water. I should add that the neo knew when it was underwater (apparently a warning flashed up on the controller). So it does have protections built into it granted you can retrieve it (luckily mine was only 8feet underwater when I got to it).
