I often need to send text messages but my only way to send is via email. No worries. All carriers have a email version of your phone number that convert emails to texts. Here is how to figure out your email to text address: AT&T – firstname.lastname@example.org Verizon – email@example.com T-Mobile – firstname.lastname@example.org 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 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
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
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 haven't posted in a while- I'm not MIA- not that I know of. I'm working hard on the PID portion of the new LCC. Its a great idea but tuning and testing is time consuming. I hope to have it wrapped up soon.
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 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!
