MATRIX BLASTER ← back to the app

Setup guide

Get a Matrix Blaster online, start to finish.

No technical background needed. Every screen below is a real photo of what you'll actually see — go slow, follow along one screen at a time, and you've got this.

What you'll need

The whole process takes about ten minutes. Take your time — there's no way to break anything by going slowly.

💡 There's also a shorter, more technical version of this guide on the firmware team's own site: dubpixel.github.io/dpx_tc002_frm/flash — worth a look if anything here is unclear.
1

Plug it in

Connect your Matrix Blaster to your computer with the USB cable. You should see it light up right away. Just make sure it's plugged directly into your computer — not into a USB hub, and not into a wall charger.

2

Flash it

"Flashing" just means installing the software onto the device — think of it like installing an app, except this app is the whole device. Click the button below to start, then follow along with each screen below in order.

💻 This needs desktop Chrome or Edge. On another browser or device, see the firmware README for an alternate install method. 🔒 This page needs to be loaded securely to flash — reload the page and try again.

This installs the latest stable release. If you specifically want a nightly (unreleased, bleeding-edge) build instead, use the firmware team's own flash page, which lets you pick a channel.

a

A window pops up asking you to pick a "port." This is your computer asking which physical device you mean. Pick the one that showed up when you plugged in your Matrix Blaster — it's usually the only option, or the one with "USB Serial" in the name. Click it, then click Connect.

Don't see anything in the list? Try a different USB cable — some cables only carry power and can't transfer data. That's the most common snag here.
b

A small menu appears with your device's name on it. Click Install.

c

You'll be asked whether to erase the device first. If this is the very first time flashing this particular device, leave the checkbox checked (it usually is by default) and click Next — this clears out anything that might already be on there and helps avoid weird boot issues.

Reflashing a device you've set up before? You can leave this box unchecked — it's only needed the first time. Your screen will look slightly different (no checkmark, no red warning text) if that's the case, and that's completely normal.
d

One last confirmation. Click Install to actually start.

e

Now it installs — you'll see a progress screen. This takes about two minutes. Don't unplug the device or close the browser tab while it's running.

The device may start beeping continuously partway through — that's completely normal. It's just electrical noise from the flashing process, not an error. It'll stop on its own once installation finishes.
Nice work. That's the hardest-sounding part done — everything from here is just typing in your WiFi info.
3

Find your device's WiFi

Once flashing finishes, unplug the device from your computer and plug it into any USB power source — a wall charger works great now, you're done needing the computer for a minute. It'll restart and start broadcasting its own temporary WiFi network, so you can tell it what your real WiFi is.

a

Give it about 10–15 seconds to boot up and start broadcasting. Then, on your phone or computer, open your WiFi settings like you're connecting to any normal network.

b

Look for a network starting with dpx-tc002- followed by some letters and numbers. That's your device — the letters and numbers after the dash are unique to your specific unit, so no two Matrix Blasters ever show up with the same name.

c

Connect to it. When it asks for a password, enter:

4

Tell it your real WiFi

Once you're connected to the device's temporary network, a setup page should pop up on its own. If it doesn't within a few seconds, open a web browser and go to http://4.3.2.1.

a

You'll land on a welcome screen. Click SET UP WIFI.

Again — the letters/numbers in the network name here will be different on your device. Everything else on this screen will look the same.

b

You'll land on the device's own WiFi settings page. It looks a little more technical than the rest of this — don't worry, you only need to touch two fields. Click Scan to have it look for nearby networks.

c

The network-name field turns into a dropdown list. Pick your real home WiFi network from it, then type its password into the field just below.

d

Scroll up and click Save & Connect. The device restarts on its own and joins your real WiFi network — its temporary network disappears once it does, which is exactly what's supposed to happen.

Heads up: the device needs a normal home WiFi network (2.4GHz). It can't join networks that need you to sign in through a browser afterward, like hotel or coffee-shop WiFi.
5

Claim it

Almost done — this is the last step. Give the device about 20 seconds to reconnect, then head back to Matrix Blaster and log in.

a

Look at the buddy list. It shows every device that's currently online — not just yours. If other people have Matrix Blasters too, you'll see their devices in there as well. Don't assume the first one you see is yours.

b

Find your device in the list. It'll be showing as unclaimed, and its name will look like the same dpx-tc002- name with those letters/numbers after it that you've been seeing since step 3 — same device, same name, the whole way through. Click identify on it. This makes that specific device beep and scroll a PIN across its own screen, confirming it's really the one sitting in front of you before you claim it.

c

A claim window pops up on its own right after you click identify. Type in the PIN you just saw (or heard beeped) on the device, and hit claim.

That's it — you're all set up! Give your device a nickname if you'd like, and start sending it messages. You did it.
