Simple Automatic Volume Control with Arduino

This was for a pair of outdoor speakers in front of KMNR, my college radio station. KMNR was receiving complaints for having the music too loud at night. An Arduino checks clock and adjusts volume using digital potentiometers This post is a walkthrough of the design and implementation. Design I interfaced an Arduino with a RTC (real time clock) to get the time. The RTC is Maxim’s DS1307 and it should last 17 years on it’s backup battery. It communicates over I2C and you can find already written code here. ...

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. ...

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. ...

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. ...

Designing and Building a CNC Machine

In May 2012, the end of my junior year of high school, I began to develop great interest in a personal CNC machine. A CNC machine is a beautiful thing, and the process of homebuilding a CNC machine emcompasses design, building, and utilization. The design demonstrates creativity and planning, building demonstrates an understanding of mechanics and craftsmanship, and utilization restarts the process at design again. A tool to make new things, limited mostly by one’s creativity. ...

Making a Computer Jog/Scrolling Wheel

The idea is simple, take the scrolling mechanism out of a mouse, and move it to a large, heavy spinning wheel of some sort. The benefits of this, scrolling long webpages and folders is tireless and editing video is a quicker process, as you are able to scrub easily and quickly. The more you use a jog wheel, the quicker and more painless navigating and using a computer becomes. ...
