Here is how to figure out your email to text address: AT&T – email@example.com Verizon – firstname.lastname@example.org T-Mobile – email@example.com Sprint PCS - … Continue reading Text To Email Addresses
HP for the most part is a pain in the butt when it comes to finding parts for servers. BUT- I found a neat resource that lets you not only find parts but specific ones based on your server serial number. Total win. It's called the HP PartSurfer. Finding a motherboard part number with just … Continue reading HP Parts Finder
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
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 haven't worked on the Tri-Temp project in a while. I am going to go through and update the code a bit to lower the memory usage based on what I've learned for the LCC projects. The original LCC code will have an update posted soon too. Mostly memory updates and a few control changes. … Continue reading Code Updates
So I want to add some kind of visual indication that my main arduino loop is still well, looping. I decided on an LED "spinner", kind of like on web pages and applications. but how to do it? After a lot of searching I found something neat. A decade counter. Seems this nice little IC … Continue reading LED Spinner!
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…
This may be useful for you if you haven't memorized the pins on the Arduino UNO R3 Handy Arduino Uno R3 Pinout Diagram.
My LCC project is growing. Too much I/O is needed! I'm exploring the I²C bus system. It seems simple enough. Direct I/O is nice but is wasteful- I've used all the I/O already on the LCC project but I still need more! Wikipedia has a great write up all about it. Now I have to apply … Continue reading Out of I/O! What to do???
