I was (and hope to again) working on a PID loop for the dragon's main light. The idea is simple- vary the heat lamp using a servo and rheostat. Some of you have expressed interest. Here are the photos of the servo setup. The code however is so bad I don't even know where to … Continue reading PID Hardware Photos
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 found time over the holidays to mess with one of my old original projects- the Tri-Temp It was very interesting to poke around in some of my original hardware/code and add some things to it. Attached is a gallery of pics from the latest incarnation. I'll add the code changes and an updated schematic … Continue reading Tri-Temp Update
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 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.
Just in case you live in total isolation, the Arduino IDE has been updated to 1.0.1. Some libraries including ethernet and wire have been updated. Get it now! http://www.arduino.cc/en/Main/Software
I've always loved electronics. Sadly I started before the internet. Now, in just a few minutes I've found some of the coolest projects for Arduino and other micro controllers. And the author (lucky larry) of this one is over seas from me. How cool is that? What a great and under appreciated resource the internet … Continue reading Random Thoughts
