Re: Solar battery charging/LED setup

Hi, first, sorry for being a bit late on the reply. Sort of embarrassing after your huge compliment. I have been out for the better part of the month. Went back to visit my parents and then spent over a week in the woods hunting and living off the land for some real Indian type of experience. I hope...

Re: Question about patching hole in RV molding

Can you find some thick, but flexible plastic to patch the hole with? My large trailer is covered all along the bottom with a thick sheet of plastic which protects everything from dirt, moisture and mice. You will need to find some very stiff glue to mount it well. The best option tho, in my opinion...

Re: Home made led light + battery charger.

Hi, I am terribly sorry for your loss. The easiest way to make this work is to use a complete solar garden/path light and just cut the wire leading to the LED and then run wires from there to your flickering candle LED. Run the wires directly into the battery compartment of the flickering candle, no...

Re: Petlier cells

That sounds like an interesting idea. I do know that Peltier elements can produce power. Apply heat to one side and heatsink the other side and you should see a potential difference (voltage). I would certainly try it first by holding the Peltier near a candle (not too close so you dont get soot on ...

Re: Bedini desulfator

Hi Chris, Welcome to The DIY World forum. The simplest schematic to follow is the following: http://www.thediyworld.com/img/img_th/th_Radiant-Battery-Charger-Schematic.jpg If you follow this schematic precisely, you should have a machine that runs right away. Make sure your bearings are very free sp...

Re: How to desulfate lead acid batteries for free

The radiant energy charger will normally cause less hydrogen emissions than a standard charger. A standard plug in charger uses brute force to push electrons into the battery, which heats up the battery and boils off the electrolyte. A radiant energy charger uses a sort of "cold" energy which does n...

Re: passive solar heater for trailer

Hi, more vent area means more air flow. I never heard of such a project, but it sounds interesting. I have heard about a lot of various projects where you heat up a mass with the sun during the day and allow the heat to flow back out at night. The whole thing needs to be insulated very well. Best is...

Making solar panels for $1 per watt

I spent a good part of the summer experimenting with homemade solar panels. I have tried out various materials in making solar panels. I have also experimented with the location of the solar panels. Homemade solar panels can be every bit as good as retail solar panels. The homemade panels can be mad...

Re: The Dollar Store Survival Bug Out Bag

Just recently returned from a dollar store survival shopping trip and got a bunch of nice items for a survival bag. Some good food items can be put away for long term storage as well. The dollar stores sometimes contain nice little hidden deals. Just look around and see what you can find. Here are s...
