I live in Southampton, studied Electronic Engineering at Southampton University, and continue to be involved with the [[http://www.suws.org.uk/Main_Page|Wireless Society]] and [[http://susf.co.uk/|Spaceflight Society]].

On IRC I am known as //craag// or variations thereof.

**My Website**: [[https://www.philcrump.co.uk/|philcrump.co.uk]]

**My Github**: [[https://github.com/philcrump/|github.com/philcrump]]

I work as an engineer at [[http://www.telemetricor.com/|Telemetricor Ltd.]]

====== Project Involvement ======

I am the lead sysadmin for the ukhas.net server, and (currently) sole developer of the ukhas.net front-end website and API.

====== Node Development ======

I started basing my nodes on the Freescale Freedom KL25z ARM Cortex-M0+ Development Boards using the mbed framework.

Following issues with the power and possible firmware bugs on the KL25z boards however, I've taken a step back to the Atmel ATMega328P/168P ICs. These are the 8-bit microprocessors that underpin the Arduino boards.

In the future I am planning to experiment with the ST Microelectronics [[http://www.st.com/web/en/catalog/mmc/FM141/SC1169/SS1817|STM32L0 ARM Cortex-M0+ ICs]], however I am waiting until the Nucleo boards become available.
