Somehow, I think my education really let me down. I’ve learned a lot about physics, math, science, and all around hackery… but I have yet to learn anything around building something truly beautiful. How do you do that? Sadly, I think this was the most beautiful thing I’ve created… and it never even made it into a real product.
Okay, so this is a cool door. But isn’t the point of a door to keep people out, in… noise out or in. Hm. This makes for a good youtube demo, but I think it stinks as a door. Maybe it would work in a museum?
If you’re starting out and intimidated by how good other people’s projects look… the truth is that they started someplace too. Just to press this topic a little further, here’s my first try at… eagle CAD, OSH park, and soldering SMD components!
The green and yellow ‘budge’ wires were my attempt to fix the problems… needless to say, there were too many to save this board. Actually, the power LED and fuse were the only Continue reading
Board loaded… begin debug!
At first I was getting some really odd values coming from the thermal sensor. There were two issues at play .
- Loose leads
- Voltage source
First, I kept getting erratic spikes and couldn’t read the voltage coming out of the sensor. At this point I was only using a Digital Multi-Meter. I thought I might have bad Continue reading
Here’s the problem… I need a temperature reading on almost all of my projects. Unfortunately, most of the off-the-shelf solutions are not as refined as I need them (example – SparkFun’s TMP102 breakout board).
These solutions are simple and inexpensive, but it only had a resolution of 0.0625C. Continue reading
My wife had asked me to build a board or box with a bunch of levers, locks, handles, and doors for my two boys. I’ve always thought that it was a good idea, I’m just not that interested in things completely mechanical. So, I decided to build a button box that did essentially what my wife wanted while also being engaging enough for me to work on.
I did some quick google searches for such boxes, and found two. I was pretty shocked that I only found two, but I did find a lot of people who wanted to build this. It turns out that most people either didn’t have the time or the task became too overwhelming. Fortunately, I’m all about simplicity and I had a hard deadline!
