Whilst I wait for some small components to come by post my thoughts have turned to the physical implementation in terms of housing, mounting and waterproofing. Not being particularly adept at metalwork and lacking tools other than a basic drill and a few other everyday items such as small files etc., I'm very keen to adapt what is already available rather than constructing anything from scratch.

With this in mind I am looking at the abundance of Garden Lights available on eBay and from other sources. Many are waterproof and include a solar panel and battery. The intention would be to ditch the LED lights and Movement Sensor and just use the housing, solar panel and battery providing that there is sufficient space to house my PCB. I've sent for what looks a suitable candidate. I hope it meets my expectations.
