I recently bought a Nokia 6100 LCD from Ebay because I am in an LCD craze phase. Since I have no need for this LCD right now, I decided to port some code over to the PIC24H minibully from Sparkfun.
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.
Here is a 4-bit LCD library for the STM32 that I based off of the LCD4BitLibrary for Arduino. It’s lightweight, but it also incorporates Arduino’s Print class.
Here is a STM32 project template that I based off of http://www.micromouseonline.com/blog/2009/10/19/another-stm32-project-template.
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.
At church, we have a projector that is close to the ceiling and far away from the audio/video booth. The remote control that came with the projector does not have a very far range. I have to get out of the booth and walk close to the back row and keep moving the remote until I get the projector to turn off or on. It wasn’t only annoying for me, but I’m sure it was distracting for the church members.
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.
So, my girlfriend bought me a STM32F103 board to play around with that has a RS-232 serial port on it to program it. Since I haven’t owned any computer in the last few years that has a serial port, I needed to get a converter.
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.
