HPC Speed Technical Support

Last updated: August 4, 2026

HPC Speed helps you practice wiring layouts as a lightweight tool: pick a level, draw connections from pin to pin, verify the loop, and keep optional records of clears that matter to you.

Main features

• Home & levels — Continue where you stopped or open the level list. Sixty tasks cover series paths, parallel branches, switches, and protective-earth bonds where the task asks for them.
• Drawing board — Drag from a green pin to another pin to place a lead. Swipe empty board space to move the page. Double-tap a switch to open or close it; double-tap polarized parts to flip them; double-tap other parts to rotate. Erase removes a wire or clears every wire on a pin.
• Verify — Checks that power can return through the loads in a way that matches the level task (including PE to Ground when required).
• Skip — A small number of skips unlock the next level without marking the current one complete.
• History — After a clear, Save Screenshot stores a local record. You can add notes, attach up to three photos, and use Save Photo to copy an image into Photos when you choose.
• Encyclopedia — Component write-ups unlock as you clear the related levels.
• Profile — Progress stats, canvas background (including Dark Focus), clear orphan snapshots, reset progress, Help, and Safety Notice.

Quick tips

• Wiring only starts on a pin. Blank areas scroll the page.
• Close switches before Verify if the level requires them.
• Fridge and washer tasks need L–N power and a PE run to the Ground stake.
• If Verify fails, read the message—extra wires, open paths, crossed leads, or reverse polarity are common causes.
• Canvas look is under Profile → Appearance.

Device & permissions

Designed for iPhone. Photos or camera access appears only when you save or attach images for history records. You can deny those permissions and still use drawing, verify, levels, and encyclopedia text.

Data on your device

Progress, preferences, screenshots, and notes stay on the device. Reset All Progress clears learning state and history files you created in the app. Clear Orphan Snapshots removes leftover image files that are not linked to a history row.

Safety note

HPC Speed is a teaching model for layout practice. It is not a substitute for licensed electrical work on live installations.
