This is why I open all power supplies before using them if at all possible.
Mounting this supply would have put the housing at mains voltage. That’s also why you should never forget the protective earth connection.
The odrive is a open source high performance brushless servo platform based on RC BLDC motors. Great Stuff!
- Two motor channels.
- 24V, designed for more than 100A peak current.
- 48V version just released.
- DC-DC converter, for brake resistor or energy storage.
- Encoder feedback for arbitrarily precise movements.
- Supports power regeneration.
- Optional use of a high power density battery means you can achieve >1kW peak power output with only a modest power supply.
- Open source: Hardware, Software
- USB Serial port — PC, BeagleBone, RaspberryPi, etc.
- CAN — CANOpen and CiA 402 is a possibility.
- UART — Arduino, mBed, etc.
- PWM — RC Recievers, Arduino, etc.
- Step/direction — Existing motion controllers
- Some general purpose digital and analogue pins
- Many types of command modes
- Goto (position control with trajectory planning)
- Position commands
- Velocity command
- Torque command
Basic information on Lighthouse and schematics
Schematics of the discrete part of a sensor node for the Valve/HTC Vive Lighthouse Tracking System courtesy of Alan Yates. More info in this thread on reddit: reddit.com/r/Vive/comments/465lqw/lighthouse_sensor_module_designs/ in Alan Yates posts here: reddit.com/user/vk2zay and in this video with him talking about it at maker faire:
Also interesting the embedded-fm podcast with Alan Yates talking about Lighthouse Development and the science behind it in general: http://embedded.fm/episodes/162
In depth analysis of lighthouse technology
For an in depth analysis of the lighthouse system read Oliver Kreylos post here: doc-ok.org
Someone made a board from the schematics. The data is on github: github.com/pdaderko/lighthouse_sensor/tree/master/hardware
Open Source implementation
There is a open source implementation of a indoor tracking system that uses the vive base stations on github: https://github.com/ashtuchkin/vive-diy-position-sensor
Official Licensing of Lighthouse Technology
Last but not least. Valve started a royalty-free licensing program to use lighthouse technology for third-party products. Licensees will need to pay $2,975 to attend a training course, but other than that, there’s no licensing fees or royalties for using the tech.
Valve provides a Lighthouse ‘Licensee Dev Kit’ to companies who apply to use the technology. It includes:
Dev Kit Contents
- A modular reference tracked object suitable for attaching to prototype HMDs or other devices
- Full complement of EVM circuit boards to enable rapid prototyping of your own tracked object
- 40 individual sensors for building your own tracked object
- Accessories to enable custom prototypes
- Software toolkit to assist with optimal sensor placement
- Calibration tools for prototyping and manufacturing
- Schematics and layouts for all electronic components
- Mechanical designs for the reference tracked object and accessories
- Datasheets for the sensor ASICs
Great idea! PixelTrack is a electromechanical signage display.
The Berlin based electronics online shop TinkerSoup is reselling electronic components of lots of tinkerers favorite companies: 4D Systems, Fritzing, Olimex, Pololu, Sharp, Smart Projects, Spark, Fun, ThingM, USGlobalsat, Adafruit
Seems the domain was sold to UK based Pimoroni
A great shop for tinkerers in Berlin is sertronics they sell online but have also a brick and mortar store. They are also an official raspberry reseller.
