Ultimate Mining Tycoon Circuit and Electronics Guide
From $20K Circuit Maker setups to Electromagnets, Tablets, and Power Core Assemblers.
The electronics chain is Ultimate Mining Tycoon’s mid-to-late cash ladder. Start with the Circuit Maker ($20K) — glass sheet + coil → circuit at +100% combined value — then climb through Electronic Tuner, Magnetic Machine (Electromagnet), Tablet Factory, Superconductor Constructor, and finally the Power Core Assembler ($4.5M). This guide maps each stage, stone-vs-metal balance, and layout habits that keep belts fed.
Reference build: v0.5.13. Cross-link Alloys and Tempering, Endgame Factory, and Machines Reference.
Electronics progression ladder
| Stage | Machine | Approx. cost | Output idea |
|---|---|---|---|
| 1 | Circuit Maker | $20K | Circuit from coil + glass |
| 2 | Electronic Tuner | ~$8.5K | +$50 (or % boost) on electronics |
| 3 | Magnetic Machine | ~$120K | Electromagnet from coil + metal casing |
| 4 | Tablet Factory | ~$2.5M | High % tablet goods |
| 5 | Superconductor Constructor | ~$1M | Alloy + ceramic → superconductor |
| 6 | Power Core Assembler | $4.5M | Casing + magnet + superconductor → Power Core (~+150% / ~2.5× era values) |
| Side | Laser Maker | ~$3.5M | Optics + gem + circuit |
| Side | Engine Factory | Mid–late | Mechanical + pipe branches |
v0.5.0 buffed Laser Maker (to 175%) and Engine Factory (to 150%) — still side grades versus a fed Power Core spine.
Circuit Maker essentials
Ingredients
| Input | How you get it |
|---|---|
| Coil | Metal bar → Coiler |
| Glass sheet | Stone → Crusher → dust → Kiln → glass (then polish if your layout uses Polisher) |
Ore Smelter leaves less free stone than Blast Furnace. If glass stalls while coils overflow, switch smelting strategy or mine stone-rich layers on purpose.
Basic circuit spine
Metal: [Smelter] → [Coiler] ─────────────┐
Stone: [Crusher] → [Kiln] → [Polisher?] ─┴→ [Circuit Maker] → [Electronic Tuner] → [Sell]Filter gems off the metal line before the smelter so jewelcrafting never clogs circuit inputs. Overflow splitters dump surplus glass or coils to sell points instead of deadlocking the maker.
Why Circuit Maker carries mid-game
Circuits roughly double combined coil+glass value and stay useful until Electromagnet / Power Core lines mature. Many players ride Circuit Maker + Tuner from tens of thousands into the low millions while saving for Magnetic Machine and Alloy Furnace.
Watch the embedded Circuit Maker tutorial for a tile-accurate belt demo, then rebuild with straight conveyors from Factory Layout.
Electromagnet layout notes
Magnetic Machine combines a metal coil and metal casing into an electromagnet (~1.5× combined value). Casings come from the Casing Machine — budget belt space for a casing branch beside your coil line. Electromagnets later feed:
- Engine Factory branches
- Power Core Assembler (with casing + superconductor)
Do not delete your Circuit Maker the moment magnets unlock — circuits still sell and feed Laser Maker.
Superconductor and Power Core
- Produce alloy bars (Alloys and Tempering).
- Make ceramic casing (clay/stonework path).
- Superconductor Constructor merges alloy + ceramic.
- Power Core Assembler merges metal casing + electromagnet + superconductor.
Starvation checklist before buying the $4.5M assembler:
- Coils never idle empty for minutes
- Alloy Furnace outputs steadily
- Ceramic line matches alloy rate
- Complexity headroom remains under 4,000

Prestige machines on electronics lines
| Prestige machine | Electronics impact |
|---|---|
| Ore Upgrader | Higher-tier ores → richer coils/circuits |
| Philosopher’s Stone | Infuse bars before coiling |
| Gem↔Bar Transmuters | Convert gem wealth into bar/coil lines |
| Duplicator | Dust/product duplication into sifters |
Spend first 3 Medals on Ore Upgrader before exotic electronics prestige toys — see Prestige Machines.
Balance reminders from v0.5.x
- Smelter stops if stone is not removed — clear stone or use blast/stone routing.
- Factory items save between sessions (v0.5.5+); saving is immediate (v0.5.12).
- Trust belt item icons over gear animations after v0.5.7.

Circuits teach dual-input discipline. Once glass and coils stay balanced, Electromagnets and Power Cores become construction projects — not mysteries.
Frequently Asked Questions
Quick answers to the most common questions.
What does the Circuit Maker need?
One glass sheet and one coil. It combines their values and adds about +100%.
When should I buy Circuit Maker?
Around $20K once you can smelt bars and crush stone into glass without constant jams.
Is Power Core better than Circuit Maker?
Yes for endgame cash, but only after alloys, casings, magnets, and superconductors run continuously. Circuit Maker remains the mid-game workhorse.
Why is my Circuit Maker idle?
Usually missing glass (stone shortage) or missing coils (smelter/coiler jam). Check both inputs and gem filters.
Do I need Electronic Tuner?
It is a cheap upgrade that adds flat value to electronics. Add it early on the circuit sell path.
