Checking prices on your phone fifty times a day is a habit most crypto holders would happily break. A dedicated desk ticker solves that: a small, always-on display that shows the bitcoin price, block height or a few coins of your choice at a glance, with no app notifications pulling you into a trading screen.
You can buy one ready-made, but building your own is a fun weekend project and costs less than a hardware wallet. Below are the two most popular DIY routes, the parts you need for each, and a few setup tips.
Option 1: A pixel clock running AWTRIX
The Ulanzi TC001 Smart Pixel Clock is a small LED matrix display that ships as a clock but can be flashed with the open-source AWTRIX firmware. Once flashed, it can show custom apps, including a bitcoin price feed pulled from a public API. Users on the Node-RED forums have shared ready-made bitcoin flows for exactly this purpose.
What you need:
- Ulanzi TC001 Smart Pixel Clock
- A computer to flash the AWTRIX firmware over USB
- Something to run Node-RED or Home Assistant, such as a Raspberry Pi 5 or an existing home server (some people run it on the same box as their node)
Rough steps: flash AWTRIX, give the clock a static IP on your network, upload a bitcoin icon, then import a bitcoin price flow into Node-RED and add a throttle so you do not hammer the price API. Community guides note you can switch between full price and abbreviated formats with a single setting.
Best for: a bright, colorful display that is easy to read across a room.
Option 2: A Raspberry Pi with an e-paper display
E-paper (e-ink) displays only draw power when they refresh and look great under normal room light, which makes them ideal for an always-on desk ornament. Open-source projects such as btcticker run on a Raspberry Pi with a Waveshare 2.7-inch e-paper HAT, pull price data from CoinGecko and refresh every few minutes. A related project, btc-ticker, also updates when a new bitcoin block arrives.
What you need:
- Raspberry Pi Zero 2 WH (the “H” means headers are pre-soldered, so no soldering needed)
- Waveshare 2.7 inch e-Paper HAT
- A high-endurance microSD card (16-32GB is plenty)
- A Raspberry Pi power supply
- Optional: a case or stand sized for the Pi Zero and HAT
Rough steps: install Raspberry Pi OS Lite, enable the SPI interface, install the Waveshare display library, clone the ticker project and run it as a systemd service so it starts on boot. Expect a short lag when the display refreshes; that is normal for e-paper.
Best for: a low-power, minimalist display that looks like a printed card.
Which should you build?
- Easiest: the Ulanzi TC001, if you already run Home Assistant or Node-RED.
- Lowest power and quietest look: the e-paper Pi build.
- Most flexible: the Pi, since you can also show block height, mempool fees or a portfolio total if you script it yourself.
Open-source projects come and go, so check each repository’s recent commits before you start. If you are setting up a full workstation around your ticker, our guide to building a crypto trading desk setup covers monitors and lighting, and node runners can pull data from their own hardware described in our Bitcoin full node hardware guide.
Security tips
- Keep it read-only. A price ticker needs public price data, nothing else. Never put exchange API keys with trading or withdrawal permissions, wallet seeds or private keys on a hobby device.
- If you show a portfolio total, use a watch-only setup or manually entered balances rather than live exchange credentials.
- Change default passwords and keep the Pi updated. Consider putting smart-home gadgets on a separate network, as we explain in our home network security guide.
- Respect API limits. Free price APIs throttle frequent requests; refreshing every few minutes is plenty.
The bottom line
A DIY bitcoin ticker is an inexpensive, satisfying project that keeps the price in view without the doom-scrolling. Pick the Ulanzi TC001 for a bright LED display, or a Raspberry Pi Zero with a Waveshare e-paper HAT for a low-power desk ornament, and keep it strictly read-only.
