Back in Sept 2010 I blogged about some of my favorite "Free" software tools and over the years I have just found a ton of neat tools that people have freely distributed, so here are some more!
I am defiantly a Texas Instruments Graphic Calculator lover. Even though I do have several Slide Rules... and know how to use them; I pick up and use my TI-89 daily.
I've never been much for RPN calculators, but I do love the HP calcs easy Unit conversion function. This was one of the huge disappointments with the TI-89; you have to actually go into menus to assign units to be able to convert them; the HP calc does it with a couple quick button presses. Below is a screen shot from the EMu48 HP Calc Emulator by Christoph Giesselink.
It has been a couple years since I've spun a set of PCB Gerbers for a home project; I've been busy trying to save the USA's Social Security program by having a few kids!
I was pretty familiar with Cadsoft's Eagle CAD but I figured if I am going to switch tools I might as well do it now while I am rusty. I downloaded and have started making a board with RS Components DesignSpark PCB. and I have to say for a Schematic/PCB tool that has no limitations on PCB size and is free.... I am impressed.
