Workspace rules

I am not a tidy person. Much like choosing components I cope with this by having rules. If you don't have rules you don't know when you're breaking them. Rules aren't mandates, they're a thing to measure against.

We have a one car garage that is an office, workshop (recently: cabinetry, concrete, casting, electronics), storage area (mostly camping and sporting equipment, couple of bikes) and gym (dumbbells, pull up bar, and a heavy bag). It's about 250 sqft for all that. It was also a makeshift co-working space for a half dozen people once a week for a ...

US Economic Growth and Personal Income Growth 1968-2014

I started reading Berkshire Hathaway's annual letter this morning and it starts off a little bullish on what 2% GDP growth means to the average (upper middle class) citizen.

The easiest data to find only went back to 1967, though the world bank went back to 1960 on GDP and population numbers. The census data covers the presidencies of Nixon, Ford, Carter, Reagan, H.W. Bush, Clinton, Bush and Obama.

At Home SMD Circuit Board Work

I make electronic things at home. Sometimes from individual components, down to designing and fabricating PCBs from blank boards. Sometimes by connecting groups of purchased modules. Surface Mount Devices sit on top of the board, while through hole components are placed through machined holes that span all layers of the board. SMD pieces have many advantages over through hole components for industry use. They're cheaper, they can be placed easily and effectively by pick-and-place machines, and the final manufacturing steps are easier and cheaper than the steps for through hole parts.

As a very quick overview of the typical ...

3d Printing Is Not For You

I would only recommend 3d printing to someone who wanted a hobby, and wanted that hobby to be 3d printing, not "having parts made on a 3d printer". The printing itself is the activity. If you have any other primary motivation your parts will fail more often than they'll succeed.

3d printing with open source tools is this weird siren's song for me. I'm an open source enthusiast and apologist. I'm an early adopter. I'm a born tinkerer. I'm a wishful inventor. I'm a programmer and electronics nerd. 3d printing theoretically ticks all ...
