⚠️ Important update (2026)
Starting January 1st, 2026, due to an international agreement of the World Postal Union (UPU), postal services no longer allow goods to be sent as registered letters with tracking. This rule applies worldwide, including the European Union.
What this means:
Tracking / safer shipping option
Tracked shipping is possible only by purchasing an upgraded shipping method (shipment as a regular parcel): 👉 https://www.tindie.com/products/18508/
Thank you for your understanding. These shipping rules are defined by international postal regulations and are outside of my control.
📦 Ready to Ship All products I offer are pre-built, tested, and ready for immediate dispatch. I maintain inventory of finished items to ensure you receive a quality-tested product as quickly as possible. I'm committed to shipping your order as soon as possible – typically within 1-2 business days of receiving payment.
🔧 What I Sell I primarily offer two types of products:
Please note: I do not sell complete component kits or beginner assembly sets. My products are designed for intermediate to advanced electronics enthusiasts who are comfortable with soldering and component sourcing. Why This Approach? I want to work with experienced makers who have solid soldering skills and electronics knowledge. However, I've designed my PCBs to be as builder-friendly as possible:
💰 Pricing Transparency You'll notice my PCB prices are higher than ordering directly from mass manufacturers. Here's why: Every product represents months of intensive development, multiple prototype iterations, and several failed batches before reaching perfection. The pricing reflects:
The fact that each piece is handcrafted at home, not mass-produced in a factory
When you purchase from me, you're supporting independent hardware development and getting a unique, collectible piece of functional art that you won't find anywhere else.
