I’ve been wanting to make my own alarm clock for some time now, since I’m unsatisfied with any alarm clock on the market (neglecting overpriced ones). I just made a quick prototype to see if I liked it or not.
I decided to use a Sanguino for my next project and I noticed that every time I reset it with the pushbutton, it would take around 10 seconds to start the program. I thought this was absurd since the regular Arduino doesn’t take that long. I decided to dive into the bootloader firmware and find out the problem. The Sanguino version I’m dealing with is v1.4 r1.
I decided this year to make a 8x8 RGB LED device to give to my girlfriend for Valentine’s Day. I had made her a heart of red LEDs two years ago and I decided to step it up a little. No, this was not a cheap solution (it cost around $100 in materials, including all the stuff I bought that I ended up not using). I spent more time on this thing than anything I have made before.
I’ve obtained two Airwick Freshmatics from a yard sale for $2. These were used in my house for a while, but it quickly became annoying to be sprayed in the face every time. So I decided to hook it up to my arduino for no reason whatsoever.
At church, we have a projector device that is hooked up to the computer that allows us to show words to a song or a video. The problem is the VGA to composite converter we have does not have a button to black out the projector. So, when I go to get a video ready to be shown, the whole congregation sees what I’m doing.
