Light programming showing some results
I’m actually seeing some results from my Light Programmer. I’m reading a photoresistor using the analog comparator on an ATmega168. Check out my previous post about the hardware, then join me after the...
View ArticleBinary Burst clock concept
I’ve been working on a new clock concept and am far enough along to start sharing some details about it. I call it the Binary Burst. The latter is because I was inspired by some vintage starburst...
View ArticlePCB order placed for Binary Burst Clock
A lot of work went into designing this board. Thanks to help from Chris Meyer and Devlin Thyne I ended up with what I think is a design that will be friendly for the PCB manufacturer. The parts order...
View ArticleSoldering the Binary Burst Clock PCB
I received the boards back from Seeed Studios two weeks and four days after placing my order. I’m shocked by the quick turn-around, especially since I selected the slowest shipping option available...
View ArticleBinary Burst Clock demonstration
I finally got around to taking some pictures and shooting some video of my assembled clock project. Above you can see it displaying time. Minutes are tracked by the blue LEDs in binary code. Each spire...
View ArticleBinary Burst Clock firmware update
I pulled out the Binary Burst Clock and did some more work on the firmware. The big change is that I’m using a different library for the i2c communications. The one I started with had some issues and I...
View ArticleWoe is me: oscillator calibration and PCB design regrets
I’ve been investigating the calibration register of the RTC chip I used in the Binary Burst clock. While doing so, I discovered some design considerations that I didn’t manage to consider while laying...
View ArticleMy first ARM project
I’ve been trying off and on for years to get into ARM development. But my insistence on using FOSS for development has proven a difficult hurdle to overcome. But recently I acquire an STM32F0-Discovery...
View ArticleLoad capacitors for Binary Burst clock crystal
Earlier in the summer I was talking to Bob Baddeley at a Sector67 meeting about my clock problems with the Binary Burst clock. I’m a little bummed out that I didn’t dig down and find the recommended...
View ArticleSnake game on an ARM microcontroller
I’m starting to get accustomed to using an ARM chip and wanted to do a small project. I’ve always enjoyed playing the game of Snake, but never programmed it myself. I present to you Snake on an ARM...
