Just a short little #blog update today - with all the good news going on around here, and the usual springtime rush of fresh energy, I'm going to be resuming work on #PETI, the homebrew #VirtualPet I started work on back in 2019.

There's just one itty bitty problem: the development branch is about six months stale and I have no sweet clue what the hell I was up to from back then.

I will be disentangling that during lab hours on my twitch channel tomorrow.

I offer my capacity for firmware & embedded partnerships. 🛠️

Focusing on software-first shops that hit a hardware wall. If you ship great code but lack an in-house team to handle microcontrollers, drivers, or IoT interfaces, I’m here to bridge that gap.

Think of me as your remote embedded extension.

Open to DMs if you’re navigating an integration bottleneck or looking for a collaborator.

A developer's note on enabling BLE Transparent Transmission for the BT401 Dual-Mode Audio Bluetooth module.

Data Flow:

Your MCU can send any data (non-AT-commands) over UART, and it will be transparently transmitted via BLE.

Any data sent from a mobile app is forwarded directly to your MCU, The module itself won't process it, giving your application full control.

Exploring the KT142A voice chip? Here’s a robust guide for developers:

🔹 Audio Prep: Optimize MP3s (remove silent segments, 16kHz recommended)
🔹 Hardware: 3V-5.2V power, PWM/DAC options, BUSY pin diagnostics
🔹 Debugging: Fix playback truncation (reduce amp capacitor to 10nF)

Real-world example: Bus announcements & Community access control

I screwed up so hard.

Does anyone in #EmbeddedDev have the document "Programming Sharp Memory LCDs"? It was a document they themselves created for the obvious purpose and no longer host.

I thought I was keeping all my datasheets locally but I can't find these ones.

I've just pushed an update to my #blog!
In this post:

• Get yourself some updates regarding the state of PETI, my ongoing virtual pet development project!
• Patch rants with unusual brevity about decisions made by major corporations.
• True facts about Patch's Starfield, Fallout 4, and Dwarf Fortress playtime statistics in Steam.
