Device: Waveshare ESP32-S3 Touch AMOLED 1.75C
ETH Ticker turns the round 1.75" AMOLED board into a live ETH/USDT ticker. It shows the price, candles,the day’s change, a 24-hour floor and ceiling estimate, order-book walls, crypto news and alerts withsound. Everything is computed on the device itself: there is no server and no account, the device talksdirectly to public market and news sources over Wi-Fi. The network work (price stream, order book, analytics, news, Wi-Fi) runs on one processor core, thescreen and touch on the other, so the interface never waits for the network.
Price — updated about once a second from the Binance stream; green after an upward tick, redafter a downward one.• Day’s change (e.g. +2.58 %) — Binance’s own rolling 24-hour change, the same number theBinance app shows next to the price. A green or red glow behind the news tab follows it; near 0 %the glow changes colour only after the new sign has held for 10 s.• Chart — hourly or daily candles with a price column on the right and a live price tag; the timershows the time until the current candle closes.• Floor and ceiling — the 24-hour estimate (see Price analysis). Under each: 1d = lowest / highestprice of the last 24 h, 1m = of the last 31 daily candles.0x513 by Dave Gold / https://513.ooo/0x513 — ETH Ticker v9.4.2 — Features and how they work 1• Top edge — battery arc (red to green, a bolt while charging), Wi-Fi state and local time.• Connection — when offline a red “connecting” pill with a countdown appears; the devicereconnects by itself (see Wi-Fi).• News tab — a light icon means new stories, a dark one means everything was read.
Price analysis
Every 5 minutes the device estimates a range the price is likely to stay within over the next 24 hours. It
is a probabilistic range, not a promise and not financial advice.
1. Expected move (sigma)
How far ETH typically moves in a day, blended from three measures: Deribit implied volatility DVOL
(weight 50 %), the daily ATR (25 %) and the realised hourly volatility (25 %), multiplied by a
self-calibration factor (step 5).
2. Bias from −1 to +1
Which way the evidence leans, combined from these signals:
EMA 20 / 50 on hourly candles.
Momentum of the trend.
Neutral at 45–55, gently to ±0.3 at 70 / 30, full at 100 / 0; damped in strong trends
(overbought in a strong trend is mostly a false alarm).
Position inside the bands; damped in strong trends.
Bids versus asks in the Binance book (5000 levels).
Who pays whom on perpetual futures: crowded longs or shorts.
Taken relative to its 2-day average (it sits near 3 for ETH): the crowd piling into longs read as contrarian-bearish, and the other way round
Market buys versus market sells.
Change in open futures positions.
Bitcoin’s direction, which ETH tends to follow.
3. Corridor
centre = price + 0.3 × bias × sigma; floor and ceiling = centre − / + 0.8 × sigma (0.8 sigma is about the
expected one-sided extreme of a day).
4. Snapping to real levels
Each side is pulled toward the strongest level nearby: order-book walls, volume-profile nodes, the
previous day’s high and low, the 24-hour VWAP and round numbers. A floor that sits on a real support
is more useful than one at an arbitrary price.

5. Self-calibration
Every hour the current estimate is stored. 24 hours later it is checked against what the price really did,
and sigma is scaled so the corridor is neither too wide nor too narrow. The pending checks are kept in
flash, so a restart does not lose a day of waiting. The project’s test suite checks the corridor width and
this calibration on a simulated 89-day market.
6. VWAP, observed
Where the price sits against the 24-hour VWAP (volume-weighted average price) is computed as a
signal of its own, but not yet used in the forecast. Every hour the device notes it and the forecast’s
bias; 24 hours later it checks which way the price really went and logs how often each was right. It
joins the forecast only if real prices show that it helps.
loading
At power-on a red and light screen with “0x513” shows the real loading progress: Wi-Fi 10 %, live price 20 %, candle history 15 %, walls 25 %, analytics 30 %. At 100 % the two halves slide apart over the already live ticker. If a source does not answer, the screen opens after 60 s once the price is live, and the rest keeps loading in the background. News and the time zone are not waited for.
Order-book walls
The chart zoomed between the nearest walls: up to three ceilings above (green) and three floors below (red) on their true price lines, candles never squeezed. A money bag marks the top, a crying face the bottom.
A wall is a price where unusually many limit orders wait: sellers above the price (a ceiling) or buyers
below it (a floor). Price often stalls or turns at walls, and breaking one usually means a strong move.
How walls are found
• The spot and futures books are summed into price bins of about $2 on a fixed grid and averaged
over refreshes, so orders that flash in and out count less.
• A bin is a wall when it is a local peak that stands out against its own neighbourhood: at least 2× the
median depth of the ±$20 around it. The book is always densest near the price, so walls are judged
locally, not against the whole book.
• The market-maker layer around the spread (about 0.25 % from the price) is never counted as a
wall.
• The 3 nearest walls above and below are kept, at least about $5 apart, each priced at its
volume-weighted centre. Round numbers fill in only if fewer walls are found.
How walls stay stable
• Hysteresis:
a new wall needs 2× the neighbourhood depth; a wall already shown stays down to
1.4×.
• Spoof filter:
a new wall is shown only after it has been seen in 3 refreshes in a row (about a minute).
Large orders placed for a few seconds to fake support or resistance are ignored.
• Dropped
after missing 3 refreshes in a row, or at once when the price crosses it, so the next wall
takes its place.
• The book is read every 20 s, every 10 s while the walls screen is shown.
Wi-Fi: always online
Up to 10 saved networks, the most recently used tried first; the radio stays on when the screen
sleeps.
• A network is saved only after real internet access was confirmed (a check against
connectivitycheck.gstatic.com). Hotel or café login pages are detected: the device shows “no
internet” and moves on to the saved networks.
• Wrong password is reported only after two refusals (phone hotspots sometimes refuse once).
• A network picked on the screen gets 12 s for the access point to answer, then one more try on any
channel, up to 25 s in all. After 3 failed rounds over all saved networks the radio is restarted.
• Only 2.4 GHz networks are visible to the ESP32-S3. An iPhone hotspot needs “Maximize
Compatibility” turned on.
Time zone and clock
The time zone is found from the device’s internet address at start and every 6 hours, daylight saving included, and kept in flash. Until the first answer the value from config.h is used.
alerts
Alerts appear for 10 s over the bottom of the main screen with an emoji and a row of price pills, with a
sound. Thresholds are in percent of the price, so the sensitivity does not change when ETH gets more
expensive or cheaper (at about $2,400, 0.4 % is about $10).
Volume confirmation
A real break comes with volume; a stop run on thin volume comes straight back. The device
compares the volume of the last 60 minutes with the hourly average of the 20 hours before, and looks
at the share of market buys. Heavy volume (2×) or the takers behind the move (at least 60 % buys up,
at most 40 % down): a wall break counts at once. Thin volume (below 0.8×) without them: it must hold
0.25 % beyond the wall or 10 s, and a new 24-hour high or low must clear the old one by 0.15 %. No alert
is ever dropped by this, only confirmed sooner or later.
Repeat rules
• The same move is never announced twice just because time passed.
• Same direction again only after another 0.6 % (big moves: 0.8 %), or for a new move that started
after the last alert and at least 3 min later (big moves: 1 h).
• A reversal is announced at once: up and down have separate rules.
• The same wall does not repeat for 5 minutes.
• With the screen off or during the video only the sound plays; the picture is shown while the ticker is
visible.
Your own alert sounds
Every alert plays a sound: the built-in one, or your own mp3 files. Put them in the sketch’s data folder
with these names and upload that folder to the device (see the installation guide); the firmware itself
does not need to be uploaded again.
• Sources (RSS, no keys):
CoinDesk, Cointelegraph, Decrypt, The Block and CryptoSlate, refreshed
every 10 minutes.
• Importance
= keywords (ETF, SEC, Fed, hacks, liquidations, ETH / BTC, listings, records, crashes and
more) plus “hotness”: a story carried by several outlets (similar titles) is shown once and ranks
higher for each extra outlet.
• Shown:
the 10 most important of the last 24 hours, newest first; numbers such as 61,800 or $5.7
never break across lines.
Reliability and diagnostics
• A memory guard pauses heavy downloads if internal memory runs low and restarts the device
safely only as a last resort, while the screen is idle.
• The serial log (115200 baud) explains what the device does: [wifi] connection steps, [walls] current
walls, [an] analytics and the 24 h direction check, [flow] the last hour’s volume and buys, [alert]
notifications, [day] the day’s change, [perf] screen frame rate, [app] a status line every 30 s.
