Granted US Patent Number 9183818

Live performance laser show for keyboard players.  Created all software, firmware, electronics and enclosure.  If you would like to see the confidential video demo in action, please email us at info@ctrnd.com

 

Handheld Laser Projector Prototypes

Two units created.  Extracted the optical engine from a Samsung SP-H03 and Optoma PK-202 Pico Projectors, and reversed engineered them to replace all LEDs by lasers for high power output.  Created an optical coherence despeckler by using a guitar string and a magnet+coil vibrating diffuser

 

Ultra-Compact 600mW RGB Laser

How much punch can we fit in such a small device?!  It could blow up balloons from 10s of feet away instantaeously

 

Single Lasers and Power Modulators

Can provide up to 1.5 Amp to a laser diode, and reach 60KHz analog modulation speed

 

600mW Dual Violet Laser

Using a polarized beam combiner to double a laser module’s output power.  Developed a custom ultra-simple magnetic precision mechanism for alignment

 

GoPro Battery Extender

Enjoy 5+ hours of non-stop recording for only $8 CAD instead of 1.5h for the $30 stock GoPro battery.  Thanks to the powerful 18650 rechargeable lithium ion cells

 

Magnetic e-Probing System

For quick setup of an electronic probing system, with dual-axis micro-positionning thumb screws

 

Universal Motor Drive Experimental PCB

This board allows experimenting with several motor driver topologies: half-bridge, full-bridge, 2 to 4 phases, stepper motors, DC, brushless, reversible, PWM, etc.  Can also be used to implement uC-based switching power supplies.

 

Camcorder Battery Extender

No more missed videos with this twin cell modification of the stock Sony battery.  Can reach over 6h of non-stop recording, even while using the LCD screen

 

Helmet Communicators Battery Extender

Uses the lithium ion 14500 cell and a voltage booster to power the Sena communicator device through micro USB connector.  Can get an extra 8h of talk time

 

FrameStreamer Express

Our USB to ILDA converter for laser graphics projection.  Connects to a RGB projector and can do up to 60KPPS with 24-bit analog color

 

Lab-Grade Analog Bipolar Adjustable Power Supply

Specifically designed for laser diode evaluation and development.  Ultra-stable output and the precision voltage adjustment can go down to a true zero, unlike most other supplies.

 

Laser Projector Galvanometers Kit

DIY laser projector kit for hobbyists.  Allows learning the basics of PID closed-loop position control.  Can do 16KPPS scan rate

 

Mobile Radio Communications and 911 for Washingthon DC

Contributed to the creation of the largest a fastest 911 system in the world:  Washington DC.  Also coded the firmware on several Motorola products in their mobile communication equipment line

 

RFID PoE Dual Antennas for Ottawa Paramedics

Custom designed a twin RFID antenna for real-time location of Ottawa Paramedics’ assets both in the building and on the road

 

RFID PoE Single Antenna

A single version of the above antenna

 

RFID Proximity Asset Locator

For manual tracking of assets in a large manufacture.  Runs on Raspberry Pi 3B+ and uses WiFi to connect to the database.  Written in C and Python under Linux Raspbian
