As some of you may know, we have a small herd of llamas and although each is easily recognisable legislation and the Llama Association of Australasia Inc. require that the animals be microchipped. As a geek, I'd also like to integrate routine monitoring of weight, so my idea is to use the embedded microchips (same as your pet FDX-B 'grain of rice' thing) to save the scale output into the relevant animal record (yup, another use of a Raspberry Pi in the steading)
