The Coriander Divide: A Polarizing Herb in Korea Coriander—often referred to as cilantro in the Americas—is a staple in many global cuisines, but in my home country of South Korea, it is arguably the most polarizing herb you can find. While the rest of the world enjoys it in tacos and curries, a vast number…
Why Custom? When Off-the-Shelf Parts Just Don’t Fit Mounting brackets for motors or reducers are essential in automation, but making them from scratch is a tedious task. Usually, I’d prefer off-the-shelf parts to save time, but occasionally, the hardware leaves you with no choice. I was looking through some of my old project logs and…
Ditching the Perfboard: Why Mill Your Own PCB? When you need clean signal processing, a perfboard covered in messy jumper wires just won’t cut it.

A Flashback to a Hot Summer (Better Late Than Never) It is currently freezing cold outside. My hands are numb just typing this. However, looking at these photos brings back the sweaty nightmare from a past summer. Yes, this incident happened quite a while ago during the peak of a heatwave. I was too busy…
The Nightmare of “Over-Gluing” Low-viscosity super glue is a double-edged sword. Its ability to penetrate tiny gaps is unmatched, but it flows like water. We’ve all been there: you aim for a tiny drop on a delicate scale model or a fine jewelry piece, but the standard bottle nozzle dispenses a massive blob, melting the…
The Nightmare Scenario I typically spend my days modifying or repairing CNC machines. But sometimes, requests come in that make me want to run away. Today’s story is exactly one of those cases: Removing Broken Bolts. Ideally, I would avoid this task at all costs. But due to certain circumstances (and perhaps a bit of…
The “Bad Hair Day” of Wiring In this post, I want to share a simple, slightly “janky,” but surprisingly effective tip for crimping spade terminals, which are common in DIY projects. If you do any kind of electronics work, you know the struggle. You strip a flexible cable (especially those with hundreds of hair-thin strands),…
