hedral.io
a series of micro-R&D projects.
we use imaginative approaches
to solve novel problems.
projects
Train detector
a portable lidar sensor for enabling traffic routing & improved rail safety.Trail proximity sensor
radar detection for interactive objects.Flood sensor
detects the presence of water on roads, sidewalks, and pathways.Cube
a general-purpose net-connected portable switch. movement and side selection change values on services like spotify and philips hue. quite magical!The Things Network
we are founding members of Norfolk’s open internet of things network. We use TTN (The Things Network) for our gateways and backend servers.crew

Q:
Can we help you with your project?
Do you have a vision that you’d like to share?
Call, email, or stop by.
We’d love to talk.
Find us evenings & weekends at Studio Colab, located in Norfolk’s historic railroad district.
fig 1. - Copper decorative treatment on a prototype cube, with sanded PLA hardware enclosure.
fig. 2 - Installation of a lidar sensor. We use a Particle Boron lte board for connectivity.
fig. 3 - Aiming the lidar. The device samples >100 times/second and we can visualize individual train cars. Solar power opens up many possibilities for placement.
We design from first principles.
Our process is a rolling one; we iterate and let results drive consecutive steps.

fig. 4 - An OmniPreSense radar. We’d like to install these in parks and along trailways to create interactive lighting experiences for residents of the city.
fig 5. - Multiple prototypes of the cube. By the 20th version, we were on to something! Our 3-d printer allows for rapid changes to designs.
fig. 6 - A lidar sensor’s “eye” view. Small devices allow for data acquistion in the most improbable of places.
Small is flexible.
As a micro-R&D project, we are able to quickly test and validate ideas for further exploration.
fig. 7 - Who says sensors have to be obtrusive? Our devices are designed for minimal visual disruption.
fig. 8 - A prosepective placement of a flood sensor along the Elizabeth River Trail. *The sensor was never installed.
“Design Philosophy.”
Make interesting objects that solve real world problems!
