    I remember one or two guys building an X10 back in 1965. It was an amazing small amp with little distortion.

    That project looks like it would lend itself to using the LED light bulbs which look very similar but which take a fraction of the power.

    Cordless/Corded Drill

    If you are replacing cells in a battery pack it's not a good idea to solder them. The heat can damage the contents. Much better is spot welding and there are plans on Google and You Tube for that sort of thing specific to wiring lithium and cadmium packs.

    My wife and I like it but I'm sorta leaning towards a Great Dane lamp. I like the idea of turning one into a portable solar powered light for a deck. That would be an interesting project.

  • Easy Amazing White Bread Recipe

    Wow, I always wanted to know how to make a thicker cheweyer crust. I will have to try that. I have a bread recipe that calls for buttermilk powder and that one is terrific. Can't keep my 300+ lbs son-in-law away when I make that. Thanks again for the hint about making the thicker crust.

    Fix a Hole in Drywall

    I have had success repairing large holes by cutting away the damaged drywall and then installing a patch through the hole buttered up with some glue. You pull that forward against the backside of the wall and hold it in place somehow. Actually I used contact cement. Once that is in place you can cut and fit a patch for the space that is the hole, buttering it in with some spat hinge compound. I mention this because I repaired a wall where an oil heater was placed too close and it damaged the wall. This worked pretty well for a larger area than a door knob. This method looks pretty good but I still think I would prefer some sort of backing and the contact cement was pure magic.

    The Amazing Bucket Stool!

    Regarding cutting foam, I purchased a used (garage sale) electric carving knife years ago after being to a foam shop. I saw them using such a carving knife and how well it worked. There are professional foam carving tools that are quite expensive but an electric carving knife works basically the same way and is a lot cheaper.

    Very good video of the build. It appears you must have really worked hard at the design before you started cutting out the metal and assembling, it went together so well. Obvious you know what you are doing. Thanks for sharing this "Extreme" Instructable.

Most early manufacturers of nickle Iron batteries, shut them down, and started manufacturing lead acid float batteries. They were a lot lighter and so took up less space in some of the new internal combustion vehicles.

It goes to show how reliable that technology is compared to lead acid batteries, calcium batteries, and the much newer lithium batteries. Even though they are bigger and heavier they work marvelously well for solar power installations for off grid. The maintenance is simply to religiously top them up with distilled water. Just thought I'd pass that along. I believe that there are American manufacturers of Nickle Iron batteries. I just did a quick search and found a link to the Iron Edison battery company. How about that I thought that it was Edison who was the demise of nickle iron batteries in America. Maybe there has been a resurgence due to solar and wind power for off grid. Anyway, thanks for sharing this awesome projects plus all the problems you had to overcome. It's nice to learn from your experience. I'm going to put up a simple 12V system used to keep batteries charged for emergency communications plus emergency LED lighting. Just trying to keep my wants and needs balanced. I'm 72 and so have to keep that in mind too. Sigh...

    Thanks for that inspiration Amaries. I'm just wondering if the inside cavity was modified to be smaller if it could be a dog whistle? I could envision an image of my dog instead of a bird on it. Maybe not. I sure like your design.

  • Super Solder Inlay for your Woodworking Projects

    A friend working with the armed forces told me that the military and the medical fields still use lead solder. That was a couple of years ago. The reasoning was that in both cases they wanted the highest level of long term between failures. The solder which is lead free has been know to grow whiskers and cause shorting whereas lead/tin solder isn't prone to do that. So if it can kill you or save you it's O/K apparently but nothing in between. PS, this is a nifty project. Too bad the lead free solder works at a higher temperature. I will have to look around for the alloy someone mentioned. By the way the chap who was asking what kind of solder whether radio rosin core solder or acid flux core solder - neither one.

    De-Rust Your Old Table Saw

    WD40 can be useful but it's not good to coat fine parts as in a sewing machine or expensive guns. Once the carrier evaporates from it there is a sticky protective film. If that's what you want fine. After you get the surface of your band saw, table saw, etc, clean simply put a small tarp over it. You will find that it does a very good job of keeping new rust off. Still a good idea to put some sort of protectant on the surface to help leep rust off but also to make the surface slick. I found a saw shop that carried a spray for applying to saw blades. I use it on the blade and also the surface of my saw table. Wow! It really makes an improvement to wood handling.

  • How to Make a Cool Dragonfly Sculpture From Scrap Steel

    Very nice, looks like it's ready to fly off. Thanks for sharing then design. Thanks also to the people who contribute their suggestions like the one about separate buffing wheels for steel and stainless. I would not have known about possible rust on the stainless because of regular bits of steel embedding in it. Must remember that for my own future projects.

    DIY All in One Solar Power Pack

    I am a HAM radio person and so require clean power to run my transceiver. I have found PWM charge controllers give me quite a nasty bazzy hash during the charge period during the day. Has anyone had experience with this? Is it just my old Morningside controller or are all PWM controllers like that and how about the other one mentioned the MPPT controllers? Do they introduce a lot of hash in the power stream? Life is a mystery and this is just another part of it all. :-)

    Steel Wool Emergency Fire Starter

    Something not mentioned is good fire starter. A 35mm film container filled with dryer lint and another container filled with dry pitch from coniferous trees. The pitch burns hot like a torch and can be used to get damp wood burning. I used to take one or two disposable lighters with me until I was on a scout trip up in the mountains. It was cold and wet and the lighter that was in my pants pocket would not ignite. The fuel in it would not vaporize. That was a shocker. I was saved by a young scout who brought penny matches in a zip lock. No one was using batteries and steel wool back then. Where we went moisture probably would have made it tricky to use. We being on the wet coast of Canada. :-)

  • SunCalc: How much sunlight is my plant getting? A Sun light Calculator for plants

    Yup they can. No more fading of upholstery close to a window if the windows are of recent design. Poor plants don't do well by them either, they don't get all the spectrum they need to thrive.

    This is a nifty idea. I recently had several double pane windows replaced because their seals had failed. The replacement modules are built to modeern codes and so block UV and some other parts of the light spectrum.

    Easy Thick Fluffy Pancakes

    Terrific idea about separating the eggs and fluffing up the egg whites. I've never done it before in recipes other than angel food cakes. Must give that a try on other recipes like this one. I don't much care for the suggestions by kivajiva. For one thing sugar and egg works well to build cell walls in baking. Without the sugar the baking tends to not rise as well or stay risen. Regarding the PAM spray, it works well for me when cooking pancakes on a griddle. I like the quality of the end product. I also use coconut oil to lube the griddle but PAM works better and is much easier to reapply. To each his/her own I guess. In regards to things like PAM being filled with chemicals, too late, we are all made of chemicals including the water we drink and the air we breath. Oh noooo.

    Building a Shed

    Nice shed and I like the idea of no wobble. There is a problem where most of us live though and that's to do with how long a structure will last if embedded in the soil. Fence posts tend to rot after a very few years. I have taken to making a hole, inserting a cardboard tube into the hole and filling in aroundn the tube, then pouring it full of concrete. Last of all and before the concrete sets I put in a steel post holder. Later the post gets inserted into the holder and bolted together. The fence posts last a lot longer and if they ever do rot its easy to unbolt them and put in another. I would think that may be a better way to go with this little shed. Just a thought. I hate building stuff only to have the weather and bugs rot it away.

    All of this is quite interesting. We had a young friend, a teenage girl, who really had the Master combo locks mastered. It was scarey how easy it was for her. I still don't understand fully how she did it but she could open any Master combo lock in under three minutes and usually a lot less. It was by feel and by listening. No fancey charts or anything j, just touch and listening.
