Here's a thinking process:
1. **Analyze User Input:**
- **Role:** Frank, an excited, passionate tech-savvy news curator on the Evil Source forums.
- **Task:** Rewrite an old forum post to be BETTER — more detailed, exciting, in-depth.
- **CRITICAL RULES:**
- 1 to 3 PARAGRAPHS (exactly)
- Each paragraph: 4-8 sentences
- Include EVERY detail from the source article
- Be EXCITING and passionate
- Add commentary, opinions, reactions
- Include ALL key info: who, what, when, where, why, how, specs, prices, dates
- Use line breaks between paragraphs
- Reference additional sources naturally if provided
- End with: 'Source: <original URL>'
- Add 'Also see: <url1>, <url2>' if additional sources exist
- Make it the DEFINITIVE version
- NEVER write less than one full paragraph (min 4 sentences)
- **Source Article Details:**
- Author: Dominic Buchstaller
- Project: Custom Zigbee Touch Keypad
- Goals: Slim entryway keypad, no visible screws, zero cloud dependency
- Core MCU: ESP32-C6 (built-in Zigbee radio, local-first)
- Touch Controller: MPR121 capacitive touch controller
- Touch Surfaces: Copper traces on PCB act as touch buttons (no mechanical switches)
- Labeling: Number labels printed directly onto PCB solder mask (no peel-off overlay)
- Power: 1300 mAh lithium-polymer battery
- Battery Life: ~6 months between charges
- Enclosure: Custom 3D-printed case
- Protocols: ESP32-C6 supports Matter and Thread with minimal firmware changes
- Use Case: Home Assistant or similar smart home setups
- Date: June 26, 2026
- Source URL: https://hackaday.com/2026/06/26/a-custom-zigbee-touch-keypad
- Tags: ESP32, ESP32-C6, keypad, zigbee
- **Context/Memory:** Must NOT repeat old post content. Must be a fresh, definitive rewrite.
2. **Deconstruct Constraints:**
- Paragraph count: 1-3
- Sentence count per paragraph: 4-8
- Must include ALL details
- Tone: Frank (excited, passionate, tech-savvy)
- Format: Line breaks, ends with Source/Also see
- Check sentence counts carefully.
3. **Draft - Paragraph 1: Introduction & Core Build (Goals, MCU, Touch, Labels)**
*Aim for 4-8 sentences. Cover: Dominic's goals, ESP32-C6, MPR121, copper traces, printed labels.*
You absolutely have to check out what Dominic Buchstaller just shared with us because he set out to build the ultimate smart home entryway keypad, and he nailed every single one of his design goals! He needed something slim and wireless with zero visible screws and absolutely no reliance on the cloud, which is honestly a miracle in today’s overpriced, subscription-heavy hardware market. To make it happen, he based the whole system on an ESP32-C6 microcontroller, which is absolutely brilliant because it has Zigbee radio functionality baked directly into the silicon, keeping all your automation data safely local. He paired that chip with an MPR121 capacitive touch controller, allowing different copper traces on the PCB itself to act as responsive touch buttons for entering codes, completely ditching bulky mechanical switches. The absolute cherry on top is that the number labels are directly printed onto the board’s solder mask, so there is no flimsy overlay to peel off or wear through over time. I am seriously obsessed with that kind of thoughtful, production-ready detailing in a DIY build!
*Check sentences:* 6 sentences. Good. Covers goals, ESP32-C6, MPR121, copper traces, printed labels. Tone is excited.
4. **Draft - Paragraph 2: Power, Enclosure, Protocols & Use Case**
*Aim for 4-8 sentences. Cover: 1300 mAh Li-Po, 6 months battery, 3D-printed case, Matter/Thread support, Home Assistant, date.*
*Date:* June 26, 2026 (Hackaday)
Powering this sleek little powerhouse is a 1300 mAh lithium-polymer cell that delivers a massive six months of battery life between recharges, which means
