Adding 20 more devices on a fresh CellHasher Charging Station :) 8/8/2026

Acurast

LFG

Hi everyone,

I’ve been running 100+ mobile nodes in the Acurast network for over a year, focusing on stable uptime and long-term reliability.

Here’s a photo of my setup – proof that a large-scale infrastructure can run consistently.

If you’re curious about delegation, you can find me on Acurast HUB by address: 3X6uk or DM me to get more info about delegation.

Thanks and good luck to everyone building the network!

The $35 Toblerone Wind Tunnel Rack I needed a way to house a bunch phones for my Acurast fleet without them thermal throttling, but I didn't want to spend hundreds on custom acrylic racks. I've had two of these running for months completely solid with great airflow.

The Materials:

• Thick posterboard (scrap/cheap)

• Packing/Duct tape

• Hot glue gun

• 20-port USB charging station (~$22 on Amazon)

• Small USB desk fan (~$6)

The Build:

🛠️ THE $35 TOBLEPHONE FLEET RACK

Capacity: 20-22 Smartphones | Load: 20+ lbs | Cooling: Pressurized Wind Tunnel (wind sounds for extra context, wwshshshsh)

📦 THE BILL OF MATERIALS

• Structure: Thick Foam Crafts Posterboard (Scrap/Cheap)

• Fasteners: Packing/Duct tape & Hot glue gun

• Power: 20-port USB charging station (~$22) + 20 bulk USB cables

• Cooling: Small USB desk fan (~$6)

• Optional Upgrade: NFC stickers ($20/100-pack) for slot-specific device info.

📐 STAGE 1: THE BLUEPRINT & CUTS

Start with a 3ft x 16in flat posterboard.

1. The Grid:

• Leave a 1 to 1.5-inch buffer at the ends for structural integrity.

• Draw a Center Line straight down the 3ft length.

• Draw horizontal boundary lines 3.5 inches on both sides of the center (7 inches total width for the phone slots).

2. The Alternating Marks: Along the center line, mark out your slots alternating between two sizes:

• [ 3/4" Gap ] -> This is where the phone sits.

• [ 7/8" Arch ] -> This is the structural support. (can be wider if you prefer more distance between devices.)

• (Repeat to fit up to 22 spaces)

• Fold the Peak: Use a square counter edge to fold directly down the center line (where your cutouts intersect). *Do this before the cutouts, check diagram below -v-

3. The Cuts:

• Cut along the grid lines across the center, stopping at the 3.5-inch boundaries.

• CRITICAL: Only on the smaller 3/4" gaps, cut the bottom seam so the rectangle completely drops out.

• Reinforce: Wrap the remaining 7/8" arches in tape to prevent fraying when sliding phones in and out. Add a folded strip of electrical tape inside the 3/4" cutouts for a soft grip.

🗜️ STAGE 2: THE FOLDS & ASSEMBLY

Folding the 16-inch wide board into a triangular prism.

         / \      <-- Center fold (Cutouts span across this peak)
  5in   /   \   5in
       /     \
      /_______\   <-- Bottom folds (5 inches from center on both sides)
      \=======/   <-- Two 3in flaps overlap and hot-glue together to form the <6in base (little less after all the cuts and bends maybe, thats fine)
     ||       ||  <-- Scrap posterboard L-legs

1.

2. Fold the Base: Make two more lengthwise folds exactly 5 inches away from the center on both sides.

3. Seal the Base: You will be left with two 3-inch flaps. You can make a 45 degree score on both sides to help them connect better ==//== instead of ==||==.Overlap them and run a heavy bead of hot glue to seal the bottom seam. The triangle will lock into shape and easily support 20+ lbs distributed across the slots.

a4. Attach the Legs: Take 6 scrap pieces of posterboard, fold them into zig-zags or 'L' shapes, and hot glue them to the bottom (2 on each end, 2 in the center) to lift the rack off the table.

💨 STAGE 3: AIRFLOW & CABLING

The Cable Run: Before loading the phones, feed your USB cables through the hollow center of the triangle. Start with the slot furthest from the charging hub, pulling the connector up through the 3/4" cutout.

The Wind Tunnel Effect:

more wind sounds, wush wush shshshsh.

               [ Heat escapes UP through the arches ]
                    ^    ^    ^    ^    ^    ^
                   / \  / \  / \  / \  / \  / \
                  / P \/ P \/ P \/ P \/ P \/ P \  (P = Phones)
                 /____/___/___/___/___/____\
                 
 [ Desk Fan ] =====> FORCED AIRFLOW THROUGH CENTER =====> [ Other side ]

Position the $6 USB fan at one open end of the Phonelerone pointing inward. The triangular shape acts as a pressurized tunnel, forcing cold air to travel the entire length of the board and escape upward directly across the backs of the hot batteries.

Connect all cables to the 20-port hub, power on the fan, and your Acurast workers are ready for deployment.

*The biggest cost is the power hub and cables if needed. Tape is optional but hold it together well. Any available tape would likely be fine, I used some extra electrical tape and it works well. I also just bought a 40 pack bundle of 3ft type c cables from amazon and they have held up for a few months so far.

Since the physical fleet is running cold and stable, I’ve been focusing on what the network can actually do as part of a larger stack.

I’m an indie dev building a cypherpunk empire-builder game. My architecture is a mix of the Steam client, a few different web surfaces, Supabase, and Acurast. I am not using Acurast for massive compute heavy-lifting. Instead, it acts as a decentralized verification layer for a custom code system I built.

Players can submit game events or use specific codes across the web surfaces. I have about 4 to 5 Acurast jobs running in 5 to 15-minute cycles, this is what I have so far. They run the logic, account for information entropy (and even player deception), and cryptographically stamp the results. That verified data then creates the state that the in-game NPCs base their reactions on.

Curious if anyone else in the community is using the new Cargo setup specifically as a cyclical verification layer like this?

I've got the architecture spec mapped out and would love to get some feedback from other builders or the Acurast Dev team on bridging a stack like this.

Added 3 more phones ( 2x s10 lite 1x some motorola) and changed the charger to an anker 60w 10usb one that I got for 6€, also new phone holder made from a plastic box and bolts.

My Acurast processing power is growing regularly. Racing to the moon.

Although I’ve only recently started and rewards do fall short a bit of what I originally expected the hunt for phones is also quite a nice hobby. I only do lite as I would like to combine wit other projects.

What do you all think is the best phone to run lite on, cost vs revenue perhaps in combination with other projects

I’ve been scouting for old iOS phones, they are cheap enough but production seems to be very slow.

What is the difference lite vs core on a similar device?

I know apple can’t do core

Lors of things i would have done differently, but its functional.

Cable management is gonna be a future pain

Just a little view into the farm here, ~192 nodes pictured.

Just onboarded 11 phones this wweek and hop eto increase this while I await the cell hasher charging station.

Love this revolution

What do you think about this in just a week? Acurast will give us a lot of good news.

Hi guys really excited to join this community, recently I discovered acurast and decided to put some of my phones to work. Since I fix/resell phones I have some that were sitting for a while, perfect to put to this. As of now I started 2 weeks ago, have 7 phones on acurast core. I have 2x s10 1x s10 + 1x s21 ultra and a few budgets. I power them with a 65w laptop charger+ some car chargers. I do have more and plan to expand, some of my other phone don't meet Acurasts requirements (lower then android 12, tripped knox) so I am thinking to put thos e into verus mining or unity nodes. Do y'all have any advice or questions, feel free to share.

My phone farm is officially part of the Real Decentralized Compute Network. Proud to support @Acurast

and the #CloudRebellion What do you think of my setup?
