Andrew Marsh has created a very impressive Psychrometric chart. I have been staring at paper versions of this thing my whole career. This one is interactive, and you can either plot on the chart or enter values.
Up until recently, I’ve been rocking an HP probook 4520 that I’ve had for nearly 5 years. I bought it on Ebay at the time because it was the most recent laptop I could find with a CDR/ DVDR built-in. The serial port was an added bonus.
I really liked this machine. It had an “executive” feel to it- with it’s brushed copper finish, number pad and clean design, it was really fun to use.
Not that it wasn’t still performing- I just wanted to get something a little more lightweight, a little faster, and a little easier to carry around.
As it’s replacement, I went back to eBay for another HP, and landed on this smaller, more compact EliteBook Revolve 810.
I’ll share more about it once I get set up and start putting it through its paces
