Tēnā koutou katoa, Ngā iwi kia ora rā,
Ngā mihi au ki te maunga ō Parapara,
I tipu ake ahau ki te tahataha o Te Waikoropupū,
Ko ingarangi te whakapaparanga mai,
Nō Aotearoa ahau,
Kei Ōtautahi ahau e noho ana,
Ko Isaac tōku ingoa,
Tēnā koutou katoa.

Hello, my name is Isaac. I am an embedded systems developer, electronics tinkerer, and PCB designer.

I design and build embedded systems that combine firmware, sensors, and physical hardware into real-time interactive devices.

A microcontroller-based affection-giving MACHINE! - Currently a work-in-progress!

• Supercapacitor powered with USB-C charging
• Over 20 minutes of on-time
• Supports custom fonts and bitmaps
• 100 multiplexed LEDs

PCB layout

A digital clock that displays time in an analog-style format.

• RP2040 firmware
• DS3231 real-time clock integration
• Capacitive touch UI
• Adaptive brightness control
• Custom LED matrix mapping

Face of the clock

Clock internals

A real-time audio visualiser using FFT-based frequency analysis.

• Arduino firmware
• Real-time FFT spectrum analysis
• Multi-band LED matrix visualisation
• Audio input switching
• OLED display support

Housing Internals

A fully functioning clock on a credit-card-sized PCB. - Currently a work-in-progress!

• On-board 2 CR2023 battery holders, one for timekeeping, one for external peripherals
• On-board switch for changing various clock functions.
• Built-in binary display.
