Nice video, simple and self-explaining. Steps are well explained as you said.Btw, do you know how to dry-age mozzarella?

I agree. I cannot understand about the "it's not a problem" followers, why is it so hard to use a simple fan or similar to reduce the fumes? Is it so expensive or requires so much time? is your health less worthy than a fan? it's "just in case", in the same way you use the seat belt of your car to be safer even when normally you won't have accidents (besides your local regulation can force you to use it). Those followers shoudl think that normally you don't have a problem therefore you don't need to use the seat belt. That is the real non sense here.Simple, would you let your kids being exposed to fumes?

Because you don't have any side effect it doesn't mean it's safe. Surely your body didn't accumulate enough lead. The problem with lead is that, once it's in your body it remains forever and reaching the critical ammount the effects appear. It's well known the lead makes changes in the brain structure and affects the neurogical connectionsI know welding professionals with no problems at all, and others have serious issues in their eyes (due to the welding light/radiation) and lungs, both using the proper safety equipment. The former will say it's not dangerous because they don't have anything... in the same way the politicians say paying more taxes is good for the country, omitting they earn 3/4 times more than average citizen and pay same or less taxes.Fumes are bad, simple. How do the...

How do they affect the person, it depends on the person, exposure time, kind of job, etc... but they are bad for you health.

It took some time to find the link again, but I think this is the best explanation about masking and ghosting I found, simple and simple:http://www.dribin.org/dave/keyboard/one_html/Anyway it's also possible to reduce or even eliminate some of these effects using software, but it's not trivial.

What about the "ghosting" and "masking"? these are usual problems to count when using matrix keypads. Some diodes (check any good source about ghosting or masking) could help.

It must be the most complete step-by-step project about supplies I ever saw, and with caculations as well, without going into deep mathematics/physics. This is not very usual, normally you get the schematic and final values, but not intermediate steps. Nice job.

I don't use this kind of systems, but what if you simply boil the water. It won't prevent all, but won't hurt and you'll get some benefits... as killing most of the bacterias, spores, etc. surely not all but mostly all. Then you can add anykind of aditives to it.

Do not forget to specify that there are two types of LDR: positive and negative. One decreases resistence with light, the other increases resistence with light (perhaps it is the opposite).

Simple and clean, good for beginers :).You should explain the differences between pre and post-increment operators "++a" or "a++" as elements in an expresion.

Simple and clean, good for beginers :).You should explain the differences between pre and post-increment operators "++a" or "a++" as elements in an expresion.I think the rest of operators should be mentioned even when the instructable is intended for beginers. Operators like << >> , [ ] -> . (cast), etc.

Looks nice. This would be a nice improvement were I used to live, with high temperatures on average... Which is the price of all your system, roughly ?

Today I increase my "dangerousity" x100 :D Simple, nice, clear instructable :D My friends will hate you.

Next time ;) you can use specific software like "Polyboard" (for design) and "Cutmaster" (for cuttings).
