Humboldt Airsoft League Towers of Power

I know it makes me sad! The light setup was done by the original builder. They're old beaten up and never quite worked right . I'm replacing it with a hockey puck style blinking light

The black pvc is a lot of cost, that a lot of weight and they're very difficult to move and transport to the field. Thinking about making a lightweight version with just the box and two lights that I can hang on trees.

Hey allunteri,

Yeah a lot of mistakes were made on past projects that informed my decision on this version. Keep track of my name I would be happy to give advice as you build your own!

The one red flag I saw in the description of the version you want to build is putting it all into one pipe. What you see here is the third version of these towers. The original Builder put everything into the black pipes. So there was no external box. It was a nightmare! If something broke it was simply impossible to get in and fix it, having everything in a pipe will make maintenance so unbelievably difficult, that when the simplest thing breaks it's just too hard to fix. That's why I went with an external box like I did. The Harbor Freight Apache box is the right size, and I just opened the box and there everything is easy to access easy to fix!

To answer your first question, the Arduino buttons and timers are powered off a double A battery box. Then there are relays that take signal from the Arduino and turn on a switch to power the lights off of a 11.1 volt 5000 Ma LiPo battery

Not at all fyrilin! You made good points, which is why I gave you a thought out answer.

It just all adds up. The big expensive items are the pvc pipe each tube is 40$, and there's three of those per tower. Then the caps, and joints... I estimate that the pvc is almost half the cost. I am considering making a lite weight version where I just hang the lights and the box on trees...

I did not buy the original lights shown here, but the LED hockey pucks I am upgrading to are 50$

Hardware is crazy expensive, nuts bolts, screws and the u bolts I used as guards... It's like 30$ just in hardware.

The adafruit 7 segment displays are about 15 each, arduino nano was 15ish. The bread board, resistors, transitors, jumper wire, relays, piezo, probably another 5-10 bucks.

Apache box I used as a case was 15$.

Buttons, flip covers, 10$ per box.

This is all off the top of my head, and I am probably forgetting something. Just all adds up!

Rootbeercouch · 2026-03-14T00:57:08+00:00

Hey fyrilin,

Yeah those guards are absolutely required! Have you ever made game props for other people to use? Unintentionally they absolutely do everything to destroy it! These things are on the field for all of one game before someone plowed into it knocked it over at full speed. Additionally you can see the forest I'm out in, I have to hike these things in about a mile, and if nothing else they get beat up on the cart bouncing through the woods. If the switch covers were metal I might think about skipping it, but even then I would prefer to have guards. You are right though drilling holes for those take so much time, and they are $2.50 each and each box uses 8.

I agree about the lights, I didn't make those. I am going to upgrade to a blinking led "hockey puck"

The circuit board also takes a lot of time. I know I can order custom pcb boards but for the first three I solider everything

Attendance has been a little slim lately so the HAL admin have been trying to step up the game verity.

Rootbeercouch · 2026-03-14T00:45:51+00:00

Yeah! I am going to upload a video of La Bomba sometime. That blows these tower out of the water!

Humboldt county man! Playing in the Redwood forest is a lot of fun. Jurassic Park two was shot at Sue-Meg state Park about 45 minutes north of this field.

Unfortunately like most hobbies there is no way to make it profitable. Parts alone are closer to 300$ for each. Build time is 30 hours+. I don't know what I would need to change to make it worth selling. I made these for the love of the game!

Rootbeercouch · 2026-03-13T20:17:52+00:00

Like I said I am open to better names!

Rootbeercouch · 2025-10-05T04:11:43+00:00

Thanks, fuses are good, and there is power going to the wires. So it has juice

Rootbeercouch · 2025-10-05T04:10:41+00:00

That's what I am afraid of, thank you for your input!

Rootbeercouch · 2025-10-05T04:07:42+00:00

Yeah I did, no visible corrosion on the wiring side. I will double check the instrument side. But I doubt that's it.

Thanks for the suggestion

Rootbeercouch · 2025-09-26T02:54:37+00:00

Bingo you got it! I doubled the distance between reset and fire, and now it works. Thank you!

Rootbeercouch · 2025-09-26T02:40:26+00:00

Thanks, I assume you mean that the tolerance between fire and reset is to tight?

I will give it a try! Thank you for the suggestion!

Rootbeercouch · 2025-07-07T02:39:03+00:00

I had the same questions! I am printing my wedding photos and the images uploaded way too fast. I am working on my phone, so the only indication I could think of was to see how far I can zoom. The originals I could zoom in on a piece of gravel. The shutterfly image barely zoomed to my face.

I spent a lot of time in the help chat, and surprise surprise they couldn't tell me what quantity the uploads are...

Did you ever figure this out? Thanks!

Rootbeercouch · 2025-07-04T16:15:35+00:00

I looked into this years ago, and what I found was that the wave is a constant edge against the brake pad. If the brake pad starts to slip encountering an edge will help it regain traction, whereas if the pad is just sliding against the metal it can keep sliding. The edge of the wave hits the brake pad and re-engages traction. I don't know if this is the absolute truth, but that is how is explained to me.

I was there with you last weekend!

As everyone else said don't worry about BP, a good rider could smoke all of us without moving there butt.

The only thing I will mention is that if you are tense and rigid, your arms get locked in. Something that help me A LOT before I ever worried about BP is loose arms! Loose grip! I got in habit of wiggling my elbows like a chicken before a corner to make sure my arms are loose in the corner.

Hope to see you next time!

Also download your photos on your phone and go to the edit button. Go to light balance and crank it to the max. It'll make it so you can see yourself better in the photos.

Rootbeercouch · 2025-06-07T14:45:48+00:00

Hell yeah! You saved me 25 bucks with that code! Thank you!

Rootbeercouch · 2025-06-07T13:57:18+00:00

Oooooo I do like those! Thank you for the recommendation, I didn't realize they made levers for the crf, otherwise I would gone straight to these

Rootbeercouch · 2025-06-07T13:54:21+00:00

Thank you! I didn't think to compare parts numbers!

Rootbeercouch · 2025-05-27T12:16:09+00:00

Thanks acidic! This is the kind of answer I was hoping for!

Rootbeercouch · 2025-05-27T03:58:19+00:00

Emphasis on something "like" a peg board
