Bluetooth Audio Haptic & Heat Board
Budget: $750 – $1,500 AUD
I already have the core components—audio transducer, haptic motor driver, heat pad and power stage—on hand. What I’m missing is the unifying switch board that ties them all together and lets everything run wire-free over Bluetooth.
Here’s what I need the finished board to do:
• Pick up an incoming audio signal (line-level) and drive the haptic motor so the vibration follows the rhythm and intensity of the music.
• Expose a simple Bluetooth interface that streams the same audio onward to an external speaker or earbuds while simultaneously feeding it to the haptic driver.
• Provide Bluetooth-based on/off control for the heat pad—no automatic temperature changes, just straightforward manual toggling from a small companion app or even a serial command set.
• Run from a single Li-ion pack (I can supply specs) and include on-board charging as well as basic battery protection.
I’ll supply all actuators, the battery, and an enclosure prototype; you bring the electronics integration:
• Schematic & PCB layout (Altium, KiCad, or Eagle—your choice).
• Firmware ready to flash on the chosen MCU/BLE module.
• A minimal Android or cross-platform demo app that shows heat-pad control and confirms audio / haptic link.
• Gerbers, BOM, and a brief test report proving haptic response matches the audio track.
If you have previous work with BLE audio routing, haptic drivers (DRV2605, etc.), or mixed-signal PCB design, that will make this move even faster. I’m happy to iterate quickly, approve each milestone, and get a functional first article in hand. Looking forward to collaborating on a compact, reliable board that turns sound into feel—and warmth—without a single wire hanging loose.
