Pure Engineering was originally started in 2006 to offer specialized consulting and design services for small projects and ideas. Then in 2014 Pure Engineering LLC was established as the growth of the consulting work and products exploded. Our services cover a wide range of skills starting from strategic planning and product development. We offer architecture development, applying engineering rigor to develop and assess technology that is suitable for the design. In most cases you need more than a piece of paper; this is where we can develop a proof of concept to help conceptualize your product. Beyond a concept, we will make a prototype to demonstrate the produce experience and shake out all the issues before moving to manufacturing. In most cases if we are involved early in the design process, we will design for manufacturing from the beginning ensuring you will be prepared for production. In some cases when you have hit a design block or impossible requirements, we will provide subject matter experts to find a solution. Finally as we are applied researchers at heart we love to apply our engineering backgrounds to develop unproven technologies, test out theories and live on the bleeding edge.


The Internet of Things is our major focus area. We have been working on IoT systems before they were called IoT. Our strength lays with low power systems that run from batteries, as well as the movement of data across low power system to get to a server. We work with a wide range of wireless technologies to support any application.

Bluetooth Low Energy

Bluetooth Low energy(BLE) is an explosive new technology in the marketplace today. We have extensive experience making sensors that connect to modern cellular phones and computers. We have proven designs that run from several uWatts of power enabling your device to run for years without a battery change. We are familiar with the entire BLE stack and can make custom protocols using COTS hardware.

We have experience with the following BLE micro-controllers:

  • Nordic nrf5x series

  • TI cc26xx series

  • Cypress PSoc 4 BLE

  • STM BlueNRG

  • Dialog SmartBond

  • and Others

Thermal Sensor Integration

We have extensive experience with FLIR Lepton Thermal Camera. We were the first to bring to market a simple to use breakout board that enabled video capture from micro-controller development boards. Several thousand systems have been shipped to date.

Radiation Sensors

We are intimately familiar Radiation Sensors. We have designed fully custom solutions for the electronics for several detector materials.

Spectrometer Sensor Integration

The Hamamatsu C12666MA and C12880MA Spectrometer are game changers in terms of size and functionality for a spectrometer. We are supporting this sensor with breakout boards and sample firmware and software to enable the DIY crowd to make sensors to improve the world and how we see it.

Android Application Development

Android is an operating system for mobile devices such as cellular phones, tablet computers and netbooks. Android is developed by Google's developers and programmers and is based upon the Linux kernel and GNU software. Android has a large community of developers writing application programs that extend the functionality of the devices. Developers write managed code in the Java language, controlling the device via Google-developed Java libraries. We have written a number of applications and are widely used by end users in the field. Some applications were downloaded over 100k on the play store. In addition to Application development we have experience with the ASOP source code and have made custom modifications to it. We have developed custom ROM’s and tools from the ASOP source code.

Software Defined Radio Hardware and Firmware

We have extensive knowledge on designing hardware for Software Defined Radio (SDR) systems as well as writing the embedded software to make them run. We are aware of noise, cross-talk, signal loss, and impedance matching that are critical in making a working system.

Ground Penetrating Radar

With a number of published articles on GPR, our staff has contributed to the GPR community and familiar with building, testing, and evaluating GPR systems. In addition to GPR, this research has carried over to sonar image reconstruction as well. A number of signal processing techniques have been developed as well that can do target identification and classification based on the signature response of and unknown target. These signal processing techniques can be applied to a number of different applications. see paper

Development Back-end

In order to support a wide range of solutions, we have had to understand the tools to make such systems. We are focused on supporting the GCC tool chain for all embedded development. We have experience with a number of different micro-controller families ranging from the AVR, AVR32, ARM M0, M3, M4, A8, PSOC5 and A9. Our back-end support also includes revision control management, selection, setup and maintenance. We are familiar with a number of revision management tools such as SVN and git. We understand project management and the tools needed to excel.

Cloud Back-end

We do full-stack development to support many applications but our focus is cloud development to support a million devices on a single server by developing server code like firmware. Our focus is using modern standard protocols such as gRPC and REST to supporting the exchanging of data to clients, and custom low overhead encrypted communications to sensors. When it’s the right solution we use graph databases to have very efficient queries that scales linearly and time series databases for archive and analytics. Our preference is to develop docker based deployments with pre-configured load balancing and proxy services, but we can utilize services from AWS, Azure, and GCS when it is the prefered solution.


Our team can build native UI's for android, iPhone, windows, MacOS, Web. We prefer to develop cross platform web based technologies that target multiple platforms to simplify development and user experiences.
