Raspberry Pi Setup Notes These are the notes I keep for initial setups of the base Raspberry Pi Linux images. They were collected from all over the internet and from personal experiences. If you find errors let me know. I’m always updating it so check back if you’re looking to add a feature that you … Continue reading Jeff’s Raspberry Pi Setup Notes
Finally got my hands on a Raspberry Pi....will this replace my Arduino? No....I don't think so...not yet anyway.... I think the Raspberry Pi will be a perfect "front end" for web enabling my Arduino. I have found that adding Ethernet to Arduino eats up a lot of precious memory. My idea is that I can … Continue reading Uh oh, Pi is in the house..
I hope to get to play with my arduino projects over the next week when I'm off for the holidays. The first hardware version of Lizard Climate Control project is still faithfully running with no glitches. The only adjustments I ever make are to the RTC which can't keep time to save its life. The … Continue reading Just no time!
Many different terms are used for the devices that run our small computing projects. In addition there are lots of different hardware/software platforms. Many are pin compatible, similar in size and function and can achieve the same result in different ways. Here are some of the common terms: Microcontroller A microcontroller is a small computer … Continue reading Microcontrollers, Embedded Systems and Single Board Computers
I've been distracted from my Arduino projects lately. Here's what's going on: It’s true. I’m a cutter. I admit it. I cut vinyl. Lots of it. My wife and I have started a tiny business selling vinyl stickers. It’s a great combination of her creativity, my technical skills and our love of sharing that with … Continue reading A Cutting Confession
Wikipedia says that a proportional–integral–derivative controller (PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems – a PID is the most commonly used feedback controller. A PID controller calculates an "error" value as the difference between a measured process variable and a desired setpoint. The controller attempts to minimize … Continue reading PID? What is it?
I wanted a way to have a "rotatable" counter to indicate that the LCC was still looping properly. I finally found something! A decade counter (as noted in an earlier post)! Now instead of pulsing one led I have a "spinner" type of effect. I don't have to keep track of where the "count" is....I … Continue reading Decade Counter!
I've been programming for most of my life. Very very rarely have I had issues with memory or lack of memory. Now that I'm hot an heavy into microcontroller programming I've stumbled across an issue that has apparently been causing me issues without me know it it. Lack of memory! The ATmega328 series chip that … Continue reading Lost Memory…
I've started on LCC 2nd Gen or LCC2 or LCC II. I don't know what to call it. BUT I do know it'll be killer. This one is going to be everything LCC 1 was not. So far I have: Ethernet 64 GPIOs A better RTC 2 OLED displays The RTC can be updated via … Continue reading The Next Lizard Climate Control…
If you've got the chops, Maker Shed has Arduino Leonardo boards for $20! Read the description though. They have more IO but have some exceptions.
