Motorcycle Seat Repair – Liquid Electrical Tape

The #1 vinyl repair kit on Amazon has 2.9 stars. And it’s not made to fix an 10″ split seam. There isn’t a whole lot you can do to hide a 10″ split, which is a problem for my 83 Kawasaki 305. A friend had success using Liquid Electrical Tape to fix the seat of a Honda CBR1000rr. There doesn’t seem to be a whole lot of talk online about this. This is the repair for people who use close-enough nail polish to touch up body paint. ...

Motorcycle Brake/Turn Light PCB

A stranger off eBay got me pulled over, from across the world. I have a 1983 Kawasaki CSR 305 that has a hint of a cafe racer. For the look, I replaced the stock brake and turn lights with a LED brake/turn light combo from eBay. It was manufactured overseas, very cheaply. typical cheap brake/turn light Something failed and the lights went out…at night…while riding. This upset the local authorities. ...

You Don’t Suck At Flying A Quad – Part II

I could have gone from 1,000 crashes to 100 crashes with a few simple pointers. There are two big reasons why you are crashing. This is for the pilots who moving from beginner and intermediate. Reason 1 - Your Brain Imagine flying a microquad in a gymnasium. You can practice a banked turn and go wildly off target without crashing. Then you bring it back toward you and try again. ...

5 Reasons Why Hovering a Quad is Really Difficult

The title says it. And you can 10x your skill development as a quad flier with the same amount of practice time. 1 - Spatial Tasks are Hard It’s easy to keep a position in 2D space, because you can place a marker or a cone on the ground. In the air, you can’t mark the spot you are trying to hover by. Targeting a point in 3D space and maintaining a quadcopter is difficult, because it’s hard to remember where that point was, especially when a little quad is zooming all around that point. ...

You Don’t Suck At Flying A Quad – You Just Don’t Know What You’re Doing

The same scene plays out everytime I see someone fly a quadcopter indoors… They lift it off the ground, hover for a few seconds, move back and forth, then a spectator roars. “Land it in my hands! " This is not easy. First, it is a not simple to hold a microquad in one position for 5-10 seconds as you lower into someone’s hand. Second, hands are small - much smaller than the floor. Third, you get some Ground Effect and maybe Vortex Ring State from hitting your own prop wash; all make holding a precise position that much harder. Fourth, if you bought a microquad, the motors heat up and slow down mid-flight - throwing off the trim you wasted an entire battery perfecting. ...

Kansas I-70 and Nebraska I-80

Trying to decide which one to take? I’ve driven both, so you don’t have to. I-80 through Nebraska runs on slow, gradual hills. Driving to from Kansas City to Denver is deceiving, because after the 5 hours through Kansas, you still have 3 hours in Colorado that looks remarkably similar to Kansas. There isn’t much along the highway either. Few towns, trees, signs, or radio stations. Highway I-70 through Kansas ...

2×15″ Home Subwoofers, Car Amp, & Server Power Supply

After half a semester of college, I learned that my 8″, 40W woofer wasn’t enough. I wanted something bigger, but didn’t want to have to upgrade again in the future. So I decided on something reasonable for any 10’x15′ dorm room - two 15″ subwoofers powered by a 1000W car amp. My goals: keep it under $400, design it so one of the two subs can be placed in a car and be powered from a 12V source (like a car battery), and build them to be as durable as possible. ...
