Thanks. I've actually used a thermal imager and found it to be quite effective. However, I'm now trying to build my own system tuned to the required temperature and the ability to interface with other components. Are there any suitable sensors/circuits, ideally giving an analogue output of the...

Hi, I'm trying to design a system which will be able to detect a hot object on a cold surface. The downside is the temperature difference is only 1 degree celcius and I'd like to use IR from a distance of about 10cm (further away preferred if possible). Does anyone with any experience of...

Well, 500mW is very powerful. Just make sure you use goggles... And the rough plan sounds ok - essentially you need a driving circuit (inc. cooling) and some way of mounting it with a lens to focus the energy. I don't know what exactly are the 'cutting limits' with this but you'll certainly...

This can be done quite simply with a laser diode (LD). For instance, extracting an LD from an old CD-RW, DVD-RW or Blu-Ray drive and building a driver circuit could give you a laser with a power output around 200mW (the average laser point is < 5mW). If this is focussed it could burn through...

Hi, I'm trying to design a solution to the problem of finding golf balls in the rough. I've had a few thoughts so far: - Image processing to detect white objects in a predominantly green environment - UV light emitter and detector to take advantage of fluoresence of the whitening coating of...
