Noisy in bed ?

Overall I am a solid fan of these energy saving lamps (CFL).  Until recently I have never experienced in the home the industrial buzzing noises of the old strip-light tube magnetic ballasts. But there is only one place when a lamp is next to my ear.  It’s a bed side lamp using a 7w CFL […]


ALOT ! Phew, the days holding a spare 100w incandescent bulb under the kitchen sink are long gone.  So how many types of bulbs do you need nowadays ? Here’s a short list I started but never finished,…… GU10 50w, 20w halogen GU10 11w megaman G9 50w halogen capsule G9 11w megaman T5 and  T8 […]

So using the beta dashboard from my Brultech ECM-1240 power monitor I can easily focus into the electrical power used by the electric oven/grill, microwave […]


I like XP embedded, there are many strong cases for using it, especially to get XP running on minimal resources to get volume device costs down whilst still having the benefits and flexibility of a mainstream OS.
