I’m a freelance developer, maker, 3d printer and moderator with a passion for building useful tools at the intersection of hardware and software. My main interests include automation, ESP devices, WLED, and open-source development. I enjoy creating tools that solve real-world problems in my own projects and sharing them with the community.

A lightweight, browser-based pixel editor designed specifically for WLED matrix devices. Design pixel art visually, preview it live, and send it directly to your WLED devices — no installation required.

Features

• Visual 2D pixel editor
• Direct upload to WLED devices
• Live preview
• Browser-based — no installation needed
• Fast and lightweight

Planned features

• Home Assistant integration
• Text rendering support
• Animation workflows
• Multi-device support

The goal is to make WLED matrices easier to use, integrate, and automate in maker and smart home environments.

• FOSS Tools of TheSpielplatz
  A collection of free and open-source tools built for my own workflows and shared with the community. Includes:
• Web Lightning Wallet
  A lightweight Lightning wallet for development and testing with LNURL auth support.

• ESP Battery Shield
  Stable power supply and battery monitoring for ESP devices.

• ESP Observer
  Simple firmware to send JSON data via WiFi with flexible configuration.

• Hardware Playground
  A collection of hardware experiments and prototypes.

• Button Phase Control
  Control system for specific phase control hardware.

• TSPI Blockclock
  Homebrew Bitcoin blockclock using Raspberry Pi Zero W and NeoPixels.

• BackupCard
  Secure offline backup solution for Bitcoin keys and critical information.

• Freezer
  Live Linux system running entirely in RAM for secure offline usage.

My current focus is expanding WLED Pixel Studio and bringing it directly into Home Assistant.

This will enable:

• Sending images directly to WLED devices from Home Assistant
• Displaying dynamic text from automations
• Creating visual smart home notifications
• Supporting animations and advanced display workflows

The goal is to make WLED matrices a fully integrated part of the smart home ecosystem.

I’m always open to collaboration on open-source, ESP, WLED, and automation projects.
