Approximately Up Wiring Guide: How to Wire & Auto Hover

Approximately Up wiring guide: why cables snap, the 5-8 tile rule, how to wire ports and logic components, and auto hover circuits (checked Aug 13, 2026).

Approximately Up demo announcement - official news header by Approximately Games

Wires in Approximately Up do not float: a cable must attach to a solid surface such as a frame or a wall, and an unsupported run of roughly 5 to 8 tiles snaps. If your circuits keep dying, press H in build mode — unsupported and unconnected wires light up red so you can fix them before switching to Fly Mode. The other classic “broken wire” is not broken at all: frame ports only plug into frame ports, and plugging one into a regular port looks connected while carrying nothing. And when a component refuses to change value, look at it and press E — clicking does nothing.

Version note: wiring behavior, component behavior and patch numbers on this page were verified on August 13, 2026 against patch 1.0.010, the latest release note we could confirm.

Why Cables Snap: The 5-8 Tile Rule

The community consensus is simple: cables must run along or attach to a solid surface, and an unsupported stretch of about 5 to 8 tiles breaks the wire. Build mode’s H key is the safety check — it highlights unsupported wires in red, and checking it before entering Fly Mode catches most mystery disconnects. This is the direct answer to the recurring “Why wires are cut?” thread: it is almost never a power problem, it is a support problem. If you are still learning the editor basics, the tutorial’s wire-and-power checks are covered in getting-started.

None of this is a bug in the cables themselves; it is how the game models wiring as something physical. Treat every run as a thing that needs a frame or wall underneath it, and route long lines along panel edges instead of through open air. The game does not warn you about a flimsy run after takeoff — once you are flying, a snapped wire simply means whatever it powered is now dead.

Ports, Frames and the Corner Mystery

Corner pieces were the most confusing wiring bug of the launch window. Before patch 1.0.009, port labels on corner blocks were misaligned with the actual connections, which made wires through corner ports look broken. Patch 1.0.009 (August 11, 2026) fixed the corner port labels, but a few players still report edge cases where labels do not continue along a frame chain — treat this as officially fixed with leftover cases (Last checked: August 13, 2026).

Frame ports are a separate trap, confirmed in a player bug report: they only connect to other frame ports. Plugging a frame port into a regular port looks fine, but the circuit is actually open, so check this first when a line is dead. On the official side, patch 1.0.009 also changed Frame Quarter With Ports so a cable connected on one side now carries through the whole frame chain, with the A/B/C/D labels matching on both sides — and the near-daily hotfix log lives in updates-and-patch-notes.

The Logic Components Directory

Logic components confirmed in the release version include Constant Number, Remapper, Delay Block, Memory, Logic Gates (AND / OR / NOR), Accumulator, Data Router, Wireless Transmitter, the BPS braking system, Fuse Box and Whiteboard. Patch 1.0.005 fixed the OR gate, which was mistakenly acting as AND at launch (Last checked: August 13, 2026). Patch 1.0.009 corrected the Wireless Transmitter’s stated range to 2,000 m — the description had previously said 100 m.

The store description frames the whole game around automation systems: link input controllers, sensors and instruments so that cables and logic gates produce magic — or chaos. Circuit components are tied to mission rewards, so new logic parts arrive as you progress. There is no official component catalog or unlock table, so this directory only lists parts confirmed in patch notes and threads. Mounting details and cockpit instruments for physical parts such as the BPS live in parts-and-instruments.

Diggrok’s demo-era build tutorial adds component-level detail: the data router has one yellow input and two blue outputs, letting one control drive two surfaces, while the power router has no direction — anything wired together is one circuit. Gates accept both power and data: a switch opens or closes fully, while a lever allows a partial opening (one crew used a partially open gate to peek out in space without being sucked out). Set a gate to your desired default state in build mode — it keeps that state on spawn, and a closed default can lock you out. Vertical levers have a side button switching 0-100 control to bidirectional (-100 to +100) for forward and reverse.

SaNT xc’s release stream adds component observations: the data hub routes one of five inputs to its output based on the pressed channel button; trajectory curvature outputs degrees while the trig functions take radians, a known quirk players work around; and circuits include NOT gates, thresholds that act as anti-windup clamps, and modulus. A too-heavy Workshop blueprint can drop the game to 1 FPS.

Setting Values: Look at the Part, Press E

The number-one component confusion is changing values. In Approximately Up you aim at a component and press E to open and edit its value; clicking on it does nothing. There is no in-game prompt explaining this, and the most common threads are players stuck trying to set a Constant Number or a Remapper. If you are holding a part, press ~ to clear your hand first, then look at the component body and press E.

The same interaction drives labels and other value fields across build mode. If the E menu does not open, step closer and aim at the component itself rather than the wire attached to it. The behavior is unchanged in the release builds we checked (Last checked: August 13, 2026).

Demo-era control notes from the same tutorial: press Left Alt in a seat to open keybind mode, and bound keys override E — use Esc to exit the seat. Levers keep their build-mode position when you spawn (a lever left at 74 makes the ship take off on spawn), and holding Ctrl while using a control gives precision mode. If the ship spins after adding bidirectional thrusters, flip the polarity switch on one thruster.

Memory, Delay Block and Constant Number

Constant Number is the fixed-value building block: it outputs a constant you set with E, and it pairs naturally with Remapper for feeding calibrated values into a circuit. The Delay Block waits a set number of ticks before passing a signal on — 60 ticks is the example players discuss — and is the standard way to sequence actions. One player on a 144 Hz display reported 60-tick delays running fast, suggesting the block may be bound to frame rate rather than real time; whether that behavior is a bug or was fixed is not yet confirmed (Last checked: August 13, 2026). No Memory or Delay Block changes appear in the launch hotfix notes through 1.0.010.

Memory is the component for keeping a value between logic steps. The most-cited deep dive in the threads and videos we reviewed is Ghgh’s Russian-language video “Как работает память” (How Memory Works, June 15, 2026). English text coverage of this block is thin, so the in-game manual’s wiring diagrams — openable from a seat since patch 1.0.008 — are the other reference players point to.

Auto Hover Logic 101: A First Circuit

Hovering is a logic problem, not a thruster problem: the standard approach wires a sensor or instrument into a logic gate, and the gate’s output into the thrusters that should hold the ship level. The community reference is SaNT xc’s “How to Build Hover Logic without any mission” (May 24, 2026), which walks through a working hover circuit built from basic blocks. The pieces above — a constant value, a delay, a gate, plus one sensor feeding real data — are all it takes.

There is no dedicated clock-signal component in the game as of August 13, 2026, so players build their own: the suggestion thread for a clock component produced a player-made timer from a NOR gate and a Data Router wired into a self-loop. For a heavier automation showcase, QuakeC’s “Approximately Up - Auto Braking Point System” (May 30, 2026) demonstrates a working auto-braking circuit built around the BPS. Note that the BPS braking system itself unlocks after the moon landing mission, so early-game ships cannot use it. Both videos are from the demo period, so treat their exact values as approximate on 1.0.x.

OwtSpectre’s demo-era systems tutorial shows the DIY route to braking: a differentiator set to 1/60 measures how fast the distance signal changes per second; multiply by -1 to get speed; distance divided by speed gives time until arrival; and you decelerate when that time equals distance/speed minus speed/max-acceleration — read max acceleration from the acceleration meter, then swap in a constant. For auto-leveling, the gyro line outputs pitch and roll tilt in degrees; feed them through division gates divided by -30 (negative flips the correction direction, 30 keeps it slow) and add the results to the joystick 3D pitch/roll signals with addition gates. Gyro line and RCS controller both need power; after the final mission, small maneuvering thrusters wire through wireless transmitters instead of the RCS controller. (demo-era)

Cable Management and Circuit Limits

For tidier builds the community advice is to wire port-to-port directly and keep runs short. Wireless Transmitters are limited in number and do not solve power-cable clutter. Players have suggested cable bundles and grate plates as a quality-of-life feature, and whether the developer plans to add them is not yet confirmed.

The demo version had a limit on circuit count, and players asked the developer to remove or expand it for release. As of August 13, 2026 the developer has not published the release version’s circuit limit. The current number is not yet confirmed.
