    Great work, but the plastic and the tiny screws might not stop a heavyweight rushing the door....Thanks for sharing.Andy

    9 Unusual Uses for Toothpaste

    Nice instructable, thanks for sharing.Some are new to me, some are not.If you would like a new one, I have used toothpaste to "shed heat" from pieces of metal (usually jewelry), so that one older repair/or joint is not damaged by the heat of a new one close to the other one....as heat travels fast over short distances in gold and silver....Also, you can make your own thermal paste for PCs and the like, check here:-https://www.youtube.com/watch?v=YZ6mQVnqNpwThen you can post :- "10 or maybe 11 Unusual Uses for Toothpaste!"RegardsAndy

  • The Single Most Effective Way to Get Rid of a Sunburn

    Putting a burn under water always helps, what was not mentioned is that it can take several hours to become effective.....Plus the water must be soothing, not hot or cold.I take a long bath, adjusting the temperature carefully.Kids I also put in the bath, and tell the to play for some hours.The test is, "does it still sting? If yes, back in the bath.I have used a T shirt kept very wet for some hours for my back, the next day, the areas NOT covered by it were red, but the main part looked as though I had not even been in the sun......This works for any burn, not just sun burn.This is a very good instructable.The next time, for smaller burns, I will try Earl Grey too.But how about an update for the time it takes? The worse the burn, the longer the treatment!!Many thanks.PS. The lady ...

In an emergency even a good moisturizer can help, but water is best and lots of it!! Take your time.

    How I Make Cool Metal Inlays

    I'm guessing, but you might think about painting or sealing the wood first maybe. Or maybe ultra fine grain wood might be best....Just a thought....I have not yet done this myself, but your experiences will help me too I feel...regardsAndy

    Very well thought out and the end result is superb.Thanks for sharing.Andy

    Ultimate Fishing Rod Holder

    Like it!! Really simple and very effective....might try it later on this year.....many thanks for your idea.Sadly the idea with the fan to cool the beer will not help much, it may even warm the beer up as just using a fan, will (at best!) only take the beer to the temperature of the air around it. You need something wet, to allow evaporation, which will cool say a beer can.....maybe a thin "jacket" made of wet foam rubber? I haven't tried it out for effectiveness though! But thats the direction needed.Also a small fan could be driven by a small solar cell, provided you are a fair weather fisherman like me nowadays!! :-)Again, super idea, thanks for sharing, a really good instructable!!Andy

    Arduino Sun Tracker Turret

    I would like to give you some food for thought, why do you need to "track" the sun with such a system?The sun is at the same horizontal angle to any particular spot on the earth, every day of the year, at the same time, if you ignore summer and winter time.......That is say at midday (forgetting slight differences due to countrywide time), the sun will be at its highest, but at the same horizontal angle, each and every day!The only difference is the height (elevation) of the sun, higher in summer and lower in winter generally, with slight differences for the equator.....Converting a 24 hour clock time to an angle of 360° , will always find the sun's direction, even when its thick cloud and even at night!!! (Think about it!) 12 midday, will usually be 180° for those liv...

(Think about it!) 12 midday, will usually be 180° for those living in the northern or southern hemisphere, if 360° is taken as being midnight!Even adjusting the elevation about 4 times a year by hand, will still achieve a similar efficiency to a complicated sun tracker's elevation.......as it will still point at the sun, even with cloud!Sun trackers often have problems when there is cloud, or an eclipse or even someone standing in the way!!!I hope that I have explained it enough for you to understand fully, that tracking the sun is really a series of "knowns"......therefore "K.I.S.S!Sorry to be so boring...... :-) You did a good job, but I feel too complicated! But do have a great day.Best regardsAndy
