1. while most knowledge is a good thing, some information is good to have , but can make one feel uneasy at the same time
http://www.bumpmylock.com is one such site that explains in very clear terms how easy it is to open almost any standard door lock or deadbolt using "BumpKeys"
they do offer more secure anti-bump locks but of cousrse thgese go at a premium price
I found a link to this sight at our 2nd link of the day
2. http://hackaday.com/ lots of intersting techie ideas and soultions, somewhat like a modern day version/blog equivelant to what used to be on the back pages of popular science magazine, that I subscribed to for years on end in my youth
Todays third site was found on hackaday as well
3. self described as "Tinkertoys for adults" http://www.formufit.com/ has PVC pipes and connectors in all the connectors you would dream about but never find since plumbers never needed water to flow "that" way in the PVC pipes
