How to build a microcontroller-driven cold brew coffee drip tower

coldBrew03

Our friend and frequent Boing Boing contributor John Edgar Park built a large cold brew coffee drip tower using laser cut parts, lab glassware, a food-safe solenoid valve, and Arduino-based controller. I'm waiting for him to invite me over for a glass of ice coffee!

I love cold brew coffee. Its rich and delicious flavor, and low acidity, means it tastes great over ice. Traditional hot-brewed coffee methods simply can’t compare; when chilled and served on ice they tend to taste diluted and acidic. I have a small commercial drip tower that works very well, however, given the fact that cold brew takes up to 18 hours to brew, it’s disappointing to finish it off in just a few drinks. You can buy large cold-brew towers, but they’re very expensive, aimed at coffee shops. I decided to build a much larger brewing tower from scratch, and to make it considerably higher precision while I was at it — drip rate is everything when it comes to cold brew — using a microcontroller-driven solenoid valve for exact drip rate.

Star Simpson is designing classic circuits from Forrrest Mims' "Getting Started in Electronics"

circuitclassics8-1_jpg_project-main-8

The talented engineer Star Simpson is designing circuits from in Forrest M. Mims' terrific 1980s electronics books published by Radio Shack. They look great!

Each circuit depicts an original, traced and hand-drawn schematic created by Forrest Mims for his iconic books Getting Started in Electronics, and the Engineers’ Notebook series. Every board includes a description of how it works, in Mims’ handwriting, on the reverse side.

Alongside the schematic is the circuit itself. Paired with the components you need to build up timeless examples such as the Dual-LED Flasher, the Stepped Tone Generator, and the Bargraph Voltage Indicator, each board is carefully designed for easy assembly recreating the wonder of learning how electronics work— whether it’s your first soldering project or your fifty-thousandth.

An inventor, maker, and toy designer shares his favorite projects

tumblr_o5a0x9Ua5J1t3i99fo10_r1_1280

See sample pages from this book at Wink.

The first thing that struck me about Make Fun!, a collection of toy and game projects from former Mattel designer Bob Knetzger, was how many of my favorite projects from the pages of Make: magazine were his. Bob has contributed to the magazine for over nine years, and this collection represents a best-of from that run (with some original projects as well). WINK’s own Mark Frauenfelder (founding editor-in-chief of Make:) also contributes the book’s introduction.

Make: Fun! features full step-by-step instructions for some 40 projects. They range from the very simple, fun, and ephemeral, such as the actuated “Ouija Be Mine” Valentine’s Day card and “Gnome Holiday Hats” to a classic “Diving Spudmarine” bathtub toy to more elaborate builds, such as constructing your own “Kitchen Floor Vacuum Former” and building a “Desktop Foundry.” Some of my favorite projects include the “Monster Candy Snatch Game” (think: Operation), the “E-Z-Make Oven” (think: Mattel’s Thingmaker), and vacuum forming your own “Tiki Masks.”

Make: did a really nice job on the production of this book. The projects are well photographed, in full color, and the instructions are well laid out and easy to follow. And there are fun little “gimmicks” that serve the playful spirit of the book (a flip-book animation on the page edges, QR-code videos for some of the projects, and colorful templates and paper project components in the back). You can see the videos, view the templates, and find out more on the book’s companion website. Read the rest
