Hidden Drawer Locking Mechanism Plans
If you’re here, you’ve probably seen my YouTube videos on the hidden drawer mechanism incorporated in my featured project bookcase. Now, take a look behind the scenes at the drawings and sketches used to create this project.

How the Hidden Mechanical Locking Mechanism Works
The hand-crafted custom bookcase requires you pull open each of the visible drawers, before a hidden control springs out and allows you to trigger the secret compartment built into what looks like a normal molding.
To make things more complex, each of the drawers must be pulled out to a certain point before the latches they control slide out of the way, similar to how the pins in a regular lock work. That finally allows a length of wooden dowel to slide out – hidden, normally, as a knot in the wood itself – and when you twist it and then push it back in, a cable tracked around the back of the cabinet allows the hidden drawer to spring out.
We’ve used this Bertazzoni cooker in a few projects, and are honored that Bertazzoni reached out to us to use this chef’s style kitchen as a design inspiration on their website.
Designed by Adam Rosengren and Chris Vanklei, this chef’s kitchen features a 70cm wide commercial grade gas Bertazzoni stove from the Master series, custom-built cabinets, poured concrete countertops, and shelves made from reclaimed barn wood.

electronic HOUSE Award Winning Theater
The goal for this award-winning theater was to create a space that was truly unique and custom by design. This theater includes state-of-the-art audio/visual equipment, glowing pillars with glass-beaded panels, and a giant oval with built-in lighting in the ceiling. It was a great experience collaborating with Admit One Cinema and interior designer Annie Tropple on this project.

Dresser w/ Hidden Drawer
This is a short little pitch video I put together for one of the editors at Fine Woodworking. The beginning part of the video was filmed on the iPhone about a month ago, but the furniture spin at the end is from 2010. The wood lock was something I saw on Matthias Wandel’s website. I thought it would be fun to incorporate it into a piece of furniture and have it control a hidden drawer. The video below shows what I came up with.
Showing Mike Prom this dresser is what got us talking about how we were going to take the hidden drawer concept to the next level. That evening we started sketching the custom bookcase and its elaborate hidden drawer mechanism.
Voted Best Cabinet Company
2013 Reader’s Choice Winner!
Each year MinnLocal.com and Minnesota Sun Newspapers conduct a reader’s choice poll giving consumers a voice to show which community businesses they felt performed the best during that year.
Readers submit nominations for this award, and a 3rd party totals the results. Everything ranging from restaurants to doctors is evaluated in this poll. Needless to say, when I found out my company was rated the best cabinet shop for the second year in a row, I was thrilled!

Multi-day moving time-lapse
How we pulled this shot off:
- To keep the lighting consistent, we covered all of the windows with tin foil. We had several “day light” fluorescent bulbs set up on stands that provided consistent lighting throughout the two weeks the flowers were blooming. That lighting setup works great for multi-day shots because the fluorescent bulbs stay cool.
- The camera is controlled by an intervalometer. Each time the camera takes a picture, a red LED light on the back of the camera illuminates. This light lets you know that the shutter is open. (For this shot, we took 3-bracketed images every third minute.)
- An Arduino Duemilanove controls the whole operation. We taped a photoresistor (a simple light sensor) over the camera’s LED light. The photoresistor reacts to the light emitted from the LED, and creates a signal that the Arduino board can measure when the LED turns on. Each time the camera’s shutter opens while capturing an image, the Arduino board knows it.
- As soon as the Arduino board receives the signal that a photo has been taken, we programmed it to wait for 60 seconds–this delay was added to ensure that the dolly will not move while the shutter is open for long exposures. After receiving the signal from the camera and waiting, the Arduino board activates a high capacity H-bridge called a Spike for five seconds.
- The Spike then powers a 2 RPM gear motor connected to the winch. The winch either pulls or lowers the dolly up or down the curved pipe tracks, which are mounted on top of fully adjustable saw horses. The gear motor runs at a fixed speed, so the duration of its runtime determines how far the dolly will move between shots.
- The robotic control of the dolly manages two variables: the frequency of the shots (set by the intervalometer) and the distance covered by the dolly between each shot (set by the Arduino board). Because the track length is fixed and the runtime of the gear motor determines the distance the dolly moves between shots, the run time essentially dictates how many images the camera will take while traversing the track. A consistent number of images means that the length of the final video will depend only on the runtime of the winch. Thus if we want to create a 10 second time lapse with shots covering three hours or ten days, we only need to adjust the intervalometer. This greatly simplifies the field programming of the dolly.
The Ultimate Party Invite/Guerilla Marketing
While I was working on my mobile website with Craig Rentmeester and having cocktails on the rooftop of The Cafeteria on a sunny summer day, we came up with a crazy-awesome idea to build the ultimate party invite.
I had just finished up an elaborate home theater project that I was super excited about, and I was in the mood to throw a big party. In addition, I was sitting on a boatload of great time-lapse footage that I had filmed throughout the entire process of the project for my demo reel. The party invite was a great opportunity to double dip, and use the footage twice.
This invitation was much more than just the video. It was a full-screen website, and it also had a mobile redirect for people viewing the invite on smart phones. More importantly, it was an all out marketing campaign. This is where Craig’s brilliance came into play. Craig is the ultimate salesman/internet marketer/fun-guy-to-work-with. He has talent, check him out: (www.relevantemarketing.com)
Craig created a custom page within my full-screen website that listed all the party information, as well as Google Maps embedded for people who needed directions to the party. There was also a link within the page that said, “Invite a friend”. When you clicked on the link, it automatically opened your email application and impregnated the body of the email with a prewritten message. All you had to do was type in your friend’s email address and press send. Pretty slick.
All in all, the party invite was a huge success. Between the website and the mobile redirect, the video was viewed over 200 times. More importantly, my portfolio got a few looks from a couple people in the industry that I really wanted to see my work.
