User Manual

What it does

The LED Stock Deck is a small, bright 64×64 pixel display that cycles through the stocks, ETFs and crypto you own (or just watch) and shows live prices, percentage changes and mini price charts.

It connects to your home Wi-Fi and pulls fresh market data automatically. You manage everything two ways:

• The knob on the device — press, turn and hold to flip between stocks, pause, change views and open the on-screen settings.
• The web dashboard — open it in any browser on the same network to add holdings, import/export, customise colours and change every setting from a full-size screen.

Prices refresh in the background roughly every 20 minutes (or, with Smart refresh on, every 10 minutes while a market you hold is open and hourly when everything is closed), and the device keeps your portfolio and settings saved even after a power cut.

Beyond stock screens, the Deck can also show a portfolio heatmap, the day's top movers, an allocation donut, your portfolio value over time, world market indices, an earnings calendar, news headlines, the local weather, a custom message, a QR code for this dashboard, your own images (including animations) and a full-screen clock — see Extra slides.

First-time Wi-Fi setup

The very first time you power on the Deck (or any time it can't find a saved network), it creates its own temporary Wi-Fi hotspot so you can tell it which network to join.

1. Power on the Deck. The screen shows Setup Mode and the network name to connect to.
2. On your phone or laptop, open Wi-Fi settings and join the network named StockDeck-XXXX (the last four characters are unique to your device).
3. A setup page should open automatically. If it doesn't, open a browser and go to 192.168.4.1.
4. Tap Configure WiFi, pick your home network from the list, type your Wi-Fi password and save.
5. The Deck saves the details and reboots itself to join your network. After a moment it shows the connecting screen, then starts up.

Finding the web dashboard

Once the Deck is on your Wi-Fi, you control its portfolio and settings from a web page. On a computer or phone connected to the same network, open a browser and go to:

deck is the device's default name. If you rename it (see The web dashboard), the address changes to match — for example http://office.local.

Reading the screen

The Deck runs as a slideshow. It shows one screen at a time and advances automatically:

• The Portfolio summary — your total value, overall gain/loss, and a scrolling list of every holding. This is the first screen on startup (unless you've hidden it).
• One screen per stock — each holding or watchlist item gets its own screen with its price, change and chart.

It pauses a little longer on the Portfolio screen (so the list can scroll) than on individual stocks. Both timings are adjustable.

The Portfolio summary screen

At the top you'll see the title Portfolio, the current time (or date), and your total value in your chosen currency. Just below is your overall gain or loss — shown as a percentage with an up/down arrow and as a dollar figure, coloured green when up and red when down. The lower half is a scrolling list showing each holding's ticker, the number of shares, and its value.

A single stock screen

Every stock screen shares the same top layout:

What appears in the middle of the screen depends on the view mode (Holdings, High/Low or Data).

The hype / momentum slash

A small diagonal line may appear next to a ticker. It only shows when trading volume is unusually high (a sign of heightened interest), and it points the way the stock is trending:

• ↗ Green slash — high interest and a bullish trend (price above its moving averages).
• ↘ Red slash — high interest and a bearish trend (price below its moving averages).

The control knob

Everything on the device is driven by a single knob you can turn and press. Here's the full set of gestures while you're watching the slideshow:

View modes

Each stock screen can show different levels of detail. Switch between them with a triple press then turn, or set a default in the menu or web dashboard.

Time periods & graphs

The period controls how far back the chart and the % change look. Change it with a double press then turn, or in the settings.

1D1W1M6MYTD1Y5YMAXMIX

About the MIX cycle

MIX is handy if you want variety. You pick up to three periods (for example 1D, 1M and 1Y) in the settings, and the slideshow shows each stock at each of those periods in turn. Set your three choices in the MIX Cycle control on the web dashboard or the on-screen Period menu.

How the 1-Day chart fills in

The 1D chart "loads in" from left to right as the trading day progresses — at midday on a normal session it fills about the left half of the screen, reaching the full width by the close. Once the market is shut, it shows the complete last session. All other periods always use the full width.

Candlestick charts new in 2.19

Prefer candles to the filled line chart? In the dashboard's Slides card set Graph style to Candles: every stock chart becomes up to 16 open/high/low/close candlesticks (green up, red down, with wicks). The change applies from the next data refresh.

On-device settings menu

Hold the knob for about half a second to open Settings. Turn to highlight an item, press to select. Items ending in > open a sub-menu. Here's the full menu:

Brightness sub-menu

• Mode — Adp (Adaptive) or Fix (Fixed). Adaptive automatically dims overnight and brightens during the day; Fixed holds one level.
• Fixed Level — the brightness used in Fixed mode (and as a fallback before the clock has synced).
• Min Level / Max Level — the dimmest and brightest points Adaptive mode moves between across the day.

Timers sub-menu

• Slide Time — how long each stock screen is shown (adjusts in half-second steps).
• Portfolio — how long the Portfolio summary screen is shown.

Time sub-menu

• Timezone — set to Auto to detect your timezone from your internet connection, or pick a manual offset (in half-hour steps).
• 24 Hour — switch between 24-hour and AM/PM clock display.
• Show Date — when on, screens alternate between showing the time and the date.

Colors sub-menu

You can recolour 13 separate elements — background, main and sub text, positive and negative values, the two chart fill colours, the pause indicator, menu title and highlight, the period-edit text, the holding icon and the watchlist colour. Select an element, then turn to adjust Red, Green and Blue in turn (press to move from R to G to B and back to the list). There's also a Restore Defaults option to undo all colour changes at once.

The web dashboard

Open http://deck.local in a browser on the same network for the full control panel. It has everything the on-screen menu does, plus portfolio management that's far easier with a keyboard. The page is organised into these sections:

The Device Settings form

The settings here mirror the on-device menu but are quicker to change:

Press Save Settings and a small confirmation appears — the page doesn't reload, so you don't lose your place.

The live preview (emulator)

In the top-right corner of the dashboard is a small live mirror of exactly what the Deck is showing right now. Click it to expand it to full screen, and drag a bottom corner to resize the small version. When it's expanded you can even use it as a virtual knob: scroll to turn and click to press — handy for testing from your desk.

Password-protecting the dashboard

By default, anyone on your Wi-Fi can open the dashboard. If you'd rather lock it down, set a password in Device Settings → Web Security. From then on the browser asks you to sign in with the username admin and your password before showing any page. Leave the field blank to keep the current password, tick Remove Password to switch protection off again.

Screensaver: images & clock

Beyond your stocks, the Deck can show a gallery of your own images and a big full-screen clock — as extra slides in the rotation, or as a fixed “screensaver” takeover, optionally only during set hours. It's all in the Screensaver section of the dashboard.

Image gallery (up to 10)

1. In the Screensaver card, choose an image file — or select several at once (up to 16) to store an animation that plays its frames in a loop. Your browser centre-crops each to a square and shrinks it to 64×64 with a pixel-accurate preview (animated selections cycle in the preview), then Add to Gallery stores it in the next free slot (ten thumbnails, each with a delete button).
2. Set the image Mode: Off, In Slideshow (each image becomes its own slide), or Fixed (the gallery rotates full-screen as a screensaver).
3. Set Each image shows (s) — the per-image duration — and Animation frame (ms) for how fast animated slots play.

Pixel-art editor new in 2.19

Click Pixel Editor to draw a 64×64 frame right in the browser: a colour picker, 1/2/4-pixel pens, a fill bucket, an eraser and a clear button. Save to Gallery puts your artwork in the next free slot — great for logos, icons and pixel doodles without any image software.

Full-screen clock

A large stacked digital clock (Google Pixel–style rounded digits, hours over minutes, with a small AM/PM in 12-hour mode) — or, new in 2.19, an Analog face with hour/minute hands (choose under Style). Its Mode matches the images: Off, In Slideshow, or Fixed. It follows your 12/24-hour Time setting. If the clock and images are both Fixed, they alternate on the image duration.

Clock extras (2.19): a small Date line in the corner, blinking Seconds markers (a seconds hand on the analog face), and Night red — between 21:00 and 07:00 the clock renders in dim red, kind to dark-adapted eyes in a bedroom.

Time windows (screensaver hours)

Each of the images and the clock has an optional Only between window with a From/To time. Turn it on to have that feature run only during those hours — e.g. set the clock to Fixed with a window of 22:00–06:00 and the Deck becomes a bedside clock overnight, then returns to your stocks in the morning. Windows wrap past midnight.

Extra slides & the Slides card new in 2.19

The Slides card is mission control for the rotation: every slide type has an on/off switch and can be reordered with the arrows. Stock screens always play first, then the enabled extras in your chosen order.

Options in the Slides card

• Info slide (s) — how long each of the new info slides stays up.
• Transition — None, Push, Wipe or Fade between slides.
• Graph style — Line or Candles (see Time periods & graphs).
• Extended-hours price — use live pre/post-market prices as the headline when available.
• Smart refresh — poll every 10 minutes while a market you hold is open, hourly when everything's closed (instead of a flat 20 minutes).
• Group filter — if you've tagged holdings with groups (e.g. “Super”, “Crypto”), show only one group's stock slides.
• Celebration confetti — when a holding's 1-day gain beats your threshold, its slide gets a shower of confetti. Entirely optional. Entirely fun.

Price alerts new in 2.19

Have the Deck grab your attention when something happens: when a price crosses a level, or when a stock moves hard in a day.

1. In the Price Alerts card, pick the exchange and ticker, a condition — Price above, Price below or 1D move % ≥ — and the trigger value, then Save Alerts. Two blank rows are always ready for new rules; clear a ticker to delete its rule.
2. When a rule fires, the panel is taken over by a flashing alert screen showing the ticker, price and condition.
3. Press the knob to dismiss it (it also auto-dismisses after 10 minutes). Each rule fires at most once per day.

Quiet hours: set a window (e.g. 22:00–07:00) during which alerts never take over the screen — they still appear in the Event Log.

Auto Invest

If you buy the same parcels on a schedule (dollar-cost averaging, salary-day buys), the Deck can record those purchases for you automatically — with each lot priced at its buy date's actual closing price.

1. In the Auto Invest card, build a Pool: each row is an exchange, ticker and the number of shares bought per cycle. Only stocks already in your holdings/watchlist are invested into.
2. Choose the Cycle (Weekly, Monthly or Quarterly), a Start From date, and a Run At time of day — pick a time after your market's close (e.g. 18:00 for the ASX) so the day's real closing price is available.
3. Tick Enabled and save. On each scheduled date the Deck adds a dated lot to each matching holding at that day's close. Lots appear in the holdings table like any other and stay fully editable.

The plan is forward-only (it never back-fills before you enabled it), but it catches up any cycles missed while the Deck was powered off. The card shows the next scheduled date and the last invested date.

Building your portfolio

Adding a holding

1. In Add New Holding Lot, choose the exchange the stock trades on.
2. Type the ticker (for example AAPL). Use the plain symbol — the Deck adds any exchange suffix for you.
3. Set the purchase date, the number of shares, and the price you paid per share.
4. Optionally add a Nickname (shown on the panel instead of the ticker — “Tesla” instead of TSLA) and a Group tag (used by the Slides card's group filter).
5. Click Add Lot. The Deck fetches the data and the new holding appears on screen within moments.

Supported exchanges:

NYSENASDAQBATSNYSEARCAJPXSSESZSEHKEXNSEBSELSEXETRASIXPARISAMSMILANMADRIDSTOOSLOTSXASXNZXKRXTWSESGXB3BMVTADAWULJSECRYPTOINDEX

The INDEX exchange (2.19) is for market indices: enter the symbol without the caret (GSPC, AXJO, FTSE, N225…) with zero shares. They show as watchlist slides and power the Indices slide.

How many holdings can it hold?

Multiple purchase lots

Bought the same stock more than once? Add each purchase as its own lot — the Deck keeps them together under one ticker and works out your average cost automatically. To manage lots, click the edit (✎) button on a holding: you can change the exchange or ticker, edit each lot's date, shares and price, remove individual lots, or add a new one in the blank row, then Save.

Sorting, editing and deleting

• Click the Exchange, Ticker or Value column headings to sort the table (click again to reverse). The on-device slide order follows the table order immediately.
• The ▲/▼ buttons (2.19) nudge a row up or down for a fully manual order.
• The ✎ button edits a holding (including its nickname and group); the 🗑 button deletes it.
• Click anywhere on a row to preview that stock live on the panel; click again to release it.

Watchlist items

To follow a stock without owning it, add it with zero shares. It appears in the slideshow labelled Watchlist instead of showing a holding amount, and it's left out of your portfolio totals.

Import & export (CSV)

Use Export to CSV to download a backup of everything. The file has seven columns: Exchange, Ticker, Date, Shares, Price, Nickname, Group — one row per purchase lot (the last two columns are optional; older 5-column files import fine). Edit it in any spreadsheet program and use Import CSV to load it back.

New in 2.19: Export Settings (JSON) backs up everything else — device settings, colours, the brightness curve, slides, alerts, themes and the auto-invest plan — and Import Settings restores it, e.g. onto a replacement Deck. Between them, a CSV + a JSON is a complete backup.

Status & troubleshooting

The corner status pixels

The Deck uses two tiny corner pixels to tell you what's happening behind the scenes:

Start-up messages

• "Input stock data" + a web address — the portfolio is empty. Open the dashboard and add a holding.
• "Syncing Time…" — the Deck is fetching the time; the clock shows once it succeeds.
• "Loading Data…" / "Fetching Data…" — the first batch of prices is on its way.

Common fixes

Firmware updates

The Deck keeps itself up to date automatically. Once a day, in the small hours of the morning, it quietly checks whether newer firmware is available and installs it if so — you don't need to do anything.

If you'd like to update on demand, you can trigger a check yourself two ways:

• On the device — open the menu and choose Check Update.
• On the dashboard — in the Firmware Update section, click Check for Updates; if one's available, an Install Update button appears.

Updates are downloaded over a secure, certificate-verified connection (firmware 2.14 and later), so the Deck only ever installs firmware from the genuine update server.
