First thing to do is create simple heater controller. My idea is to use PWM signal what will turn on/of heating element, and because PWM is running more than 1kHz, i can get very fine power control. Here is original circuit:Idea very simple. First i...
1) Come up with a simple good idea.2) Add good ideas to it.3) Try to implement it.4) When it fails, start to strip down the design to try to get it to work.5) Strip it down more6) More...7) Rejoyce when something simple works8) Add a few simple things...
Have them cut the boards for you to these specs:Board #1 and 2: 20.75", then 20.75", then the remainder should be cut in half (will be 27.25" each, minus whatever is converted to sawdust)Board #3 and 4: Just saw these in half: 48" long.This will give...
Add your gear. Use more wood screws to secure faceplates to the wooden posts. For small items like cable modems and wireless thingamajigs, you can put wood screws into the side and hang them (most of these have special slots, as if they were......

Get and keep everything clean, including the back of your fabric. When you roll up the screen, the back touches the front, and any dirt will transfer right into the middle of your new screen. Take the actuator arm off the wiper motor. See what the threads...
Keeping the screen tensioned is what keeps it flat. I provided the needed tension almost all in the vertical axis with weight. Take a scrap of your screen fabric, and test how hot you can get an iron on it, before it melts. Three layers, and two are...
The light block fabric is actually three layers. White on both sides, with black plastic in between, but you are still painting fabric so you may have to experiment to get it right. Lay your light block fabric out on some hard clean surface. Don't step...
Get help. Clean yourself. Clean the floor. Wash your hands often. Look for the weld line on the post, or otherwise establish a line along it's length. Line up your fabric with this line, and tape across the joint, applying slight tension the the fabric....
Drill two holes, almost all the way through, two blocks of something the same size as the outer diameter of your roller blade bearings. It's a common size like 3/4 or 7/8in. Make them identical. For the hole you are after, you need a nut on the threaded...
Take your other coupler nut, and fashion a small post coming off of it at a 90 degree angle. I welded mine. Take your corner brace, and make a second post behind the first, the thickness of the corner brace, so the main post slides on the front, and...
