I’ve got my new Gorton 256-6 grinder in the shop along side the P1-2 engraver! I’m excited to have it back in the shuffle. They look very different under the light! 
The Gorton brothers are in their new home!

Herman Miller Chair repair
My Old Herman Miller wheels were really ruining my floor. This is something you don’t really think about until it’s too late…
I ordered hardwood floor safe wheels for my chair. I really recommend them for any surface… the soft rubber really keeps your floor looking new.
While I had the chair upside down I thought I’d share a mod I do to them. If you’ve spent a lot of time in these chairs you’ll know the KLANG the legs make… to keep that klang down to a minimum I Supper 77 in some scrap acoustic foam to the legs.

Finished a project for school
I had to build a 1 watt Class AB – Amplifier for an Electronics devices course. The school has an LPKF PCB prototyping machine to make these PCBs with. I’m not going to turn down the chance to have the boards made up so any project that involves PCB layout, I will over do it! The machine does 2 sided boards and with a special baking process plates the holes. I only learned this after I spent all the time making it single sided with a ground plane on top. So many lessons learned on this one.
After two revisions and some trace cutting, she’s alive. I used some Phoenix connectors on the board for connection. I will never make a board without some simple way to connect or disconnect it. Also, the idea of a PCB copper heat-sink was a bad idea. I imagine the copper has to be thin for the machine to router… so chunks of aluminium were added on the back. Thing gets rather hot. 
I was at a convenience store…
It’s almost cheaper than iTunes…

Time to clean your office chair
I moved my chair into the sunlight for the first time in…
Sure enough it needed a cleaning. The casters were beyond cleaning, so new ones with Rubber wheels (for the hardwood) have been ordered.
This chair kicks serious ass!

RLC calculator for components in series
I’ve been calculating a lot of components in series lately for an ECR255 class. I’ve also had to graph them on impedance diagrams and a power triangle.
In an effort to better understand the math I made a calculator for myself. Here is it for you to use and enjoy. If you see any problems please let me know. It was designed in excel 2011 for mac… there WILL be compatibility issues and I hope they’re minor.
How it works:
You can fill int the info you have in the orange boxes. Once the boxes are filled in the calculator should fill in the rest.
If you need to modify anything else, it’s all dependant on the orange boxes. I suggest a goal seek by modifying and orange cell.
Hairball build
All things considered the build is going well.
The leads from the supplied output transformer could have been longer… and if anyone knows a good way to remove paint for grounding posts let me know :-)
Making a game show trigger system
I got a text from a friend asking about designing a game show system that triggers sounds…
he caught me JUST as I was walking out of a digital systems class… lucky for him I’m getting better at learning about FPGAs
schadow switch mounting information
In the 70’s and into the 90’s WBS used a Schadow switch in almost every product they built. Different buttons required different offsets so “GOLDEN RULES” of design were made up so each engineer was on the same page. I found two of those pages the other day and was fascinated. These drawings are both done by hand and are admirable.
