Robo Crab
(mini-project)
When I found out we were paying $200 every few weeks to replace the mechanical robot in one of our exhibits, I knew there had to be a better way. I worked with volunteer Paul Stankiewicz to create a durable, low-maintenance, and affordable replacement. The Robo Crab uses an over-sized motor, linear guide rail, and pivots with bushings and shoulder screws.
Materials cost around $200, and thanks to Paul’s generosity, it only took a little bit of my labor to manage the project.
Fenner Nature Center Concepts
After seeing my designs at Impression 5, Fenner asked me to conceptualize a new space to reinvigorate their aging exhibit area.
Build Zone
This was a very quick, low-budget project to fill a gap made by a departing traveling exhibit. Other staff developed the activities, and I designed the exhibit layout, look and feel, and environmental treatments. The project took 2 months from initiation to completion.
It turned out to be one of the most popular exhibits in the museum.

Pan-Tilt-Zoom Camera Controller
Electrical vs Mechanical
When it comes to hands-on exhibits, I usually favor mechanical solutions over electrical because mechanical methods are more obvious to the user, often allow for wider exploration, and often require less maintenance. However, there are times when circuits make sense. I have the ability to design and implement simple circuits, including PCB design and integration with consumer/commercial electronics.
The Project
I was tasked with creating a camera setup that would allow visitors to remotely view birds at a feeder. Unable to find a kid-proof control interface, I created a controller that allows a pair of Suzo Happ analog joysticks to control a Sony EVID70 commercial grade pan-tilt-zoom camera.
The software allows a technician to easily change various parameters (such as maximum zoom, pan/tilt ranges) with a laptop via a serial interface.

Silent Spring
The Challenge
The MSU Museum contracted me to design an exhibit about the impact of Rachel Carson and Silent Spring. There was a lot of text but not many artifacts, so I did my best to add images and compartmentalize the text to make it easier to skim. Because the exhibit would travel, I was required to put all text and images on 4×6′ panels. I designed backdrops to the panels to connect them and unify the gallery.
Handy Hydros
Goals
Design and build portable activities that demonstrate hydraulics in action
Design Details
- Challenge: Facilitators can set up a challenge, such as saving a metal toy dinosaur from a vat of acid, and the user moves the magnet to complete the challenge
- Durability: I wanted to make the activities out of everyday materials, but it still had to be durable enough to withstand being disassembled and packed for school visits. The devices didn’t need to be bombproof because a staff facilitator mediated the activity at all times.
- Service: I used shoulder screws, bushings, and threaded inserts (tee-nuts) to make service as easy as possible. The syringes are held by a press-fit collar and can be removed without tools.
Portable Demo Devices
Goals
- Build demonstration devices for the MSC Traveling Science Program, which visits schools in Maryland and surrounding states and performs science shows on stage for large audiences.
- Improve on older designs, which were difficult to set up and take down, and just didn’t work very well
- Keep items compact for easy transport
Design Details
- We used simple yet durable materials to make the experiments more relatable, especially since audience members would not be able to touch the experiments.
- Designed to be maintainable by Education staff, who may not have mechanical experience
