Sugo Music Dashboard

Wed, 27 Jan 2021 00:00:00 +0000

Sugo Music is an online Music publishing platform for Artists by artists. It was my responsibility to manage the software process, build and test the backend and manage the front-end development in React.

Go, React, REST API, HTTP, HTML, JavaScript, Webapp, fullstack

Sahara Networks

Wed, 27 Jan 2021 00:00:00 +0000

Sahara Networks is building something truley unique, connecting micro-controllers and IoT devics across the network allowing virtual circuits to be created. I help design, develop and lead the design and implementation of the network protocol that delivers high speed digital I/O signals across a “device network”.

Backend, C/C++, nodejs, TCP/IP and Raspberry Pi

Radian Laser

Mon, 01 Jul 2019 00:00:00 +0000

Radian is a small, fast moving startup that sells Laser Engravers and Cutters. I manage five software projects, including two Web Applications for the control and calibration of the Laser system. I am also responsible for the successful delivery and maintanance of the products Firmaware and Fleet Management system.

C/C++, Go & Python, embedded systems and microservices.

Red Eye Video Server

Fri, 24 May 2019 00:00:00 +0000

The Red Eye project is a service definition rapper around inexpensive cameras attached to inexpesive micro-controllers that take pretty good video.

The video streams are built using the GStreamer library. The camera native capabilities are used to extract as high quailty, realtime images possible.

The video streams will be consumed by one or more sinks, including but not limited to Files, cloud storage, High Def Display and Computer Vision libraries.

Skid Steering

Wed, 15 May 2019 00:00:00 +0000

Skid steering basics

Based on fixed direction wheels[1] or tracks
There are two groups or sides of wheels: left and right
All wheels in a group MUST always point in the same direction
All wheels in a group MUST always rotate at the same rate
Direction is determined by the speed of the two wheel groups
- To move straight all motors rotate at the same rate
- Forward and Reverse are determined by positive and negative values
- Turning is achieved by varying the throttle on the right and left

Example

The Skidder class has the following API, as you can see all of the movements we desire can be accomplished with a single API call skidder.set_throttle(left_throttle, right_throttle), does not get much simpler than this!

Raspberry Pi Motor Control Software

Tue, 14 May 2019 00:00:00 +0000

This software adds a Skid Steer motor control software to the Raspberry Pi Device Server device server. RPID adds motor controls accessible via both MQTT and REST APIs, as well as directly with the Skidder python library.

MQTT For Controllor Communication

Fri, 03 May 2019 00:00:00 +0000

The MQTT message bus is a simple but critical element of our MBR software design. MQTT provides what is known as a publish/suscribe or pubsub communications model. This model of machine to machine communication has some attractive benefits for realtime driving algorithms that we will discuss in this post.

TLV the Type Length Vector Protocol

Wed, 17 Apr 2019 00:00:00 +0000

TLV is a very simple communication protocol that can be used to send messages around a complex, distributed system.
