Kingblade x10iii tuning tool

I built this to keep my old Kingblade x10iii penlights usable after the official companion app started failing in modern setups.

The original workflow became unreliable for two practical reasons:

• newer Android versions made app install/usage fragile
• iOS hardware/workflow changes (including no headphone-jack assumptions) broke the old programming path

I took an existing community IR-generation approach and rebuilt the usable layer around it: UI, QR workflow compatibility, presets, and practical error-handling.

What I implemented

• x10iii tuning flow without depending on the legacy app
• QR import/export compatibility with common Kingblade workflow patterns
• Preset save/load and local persistence
• Light/dark UI and EN/JP support
• Real-device compatibility adjustments based on actual programming behavior

Engineering challenges

The hard part wasn’t UI alone — it was making the programming loop actually work on hardware:

• protocol behavior validation against real outputs
• cross-device inconsistency handling
• unstable USB dongle behavior and workflow workarounds

Practical impact

• I actively use this tool myself
• It brought 4 of my old penlights back into usable state
• Known limitation: low-battery penlight resets still happen sometimes, so occasional reprogramming is needed

Status

Active, but in maintenance mode.
