How to Select Electronic Components

These are some great articles by Octopart on how to select components. There are definitely times where you have to delve deeper than your supply voltage and amperage ratings. These articles are great at covering more of the nuances.

How to select voltage regulator
How to select a capacitor
How to select a resistor
How to select an inductor
How to choose a connector
Octopart guide ic packages
How to choose a microcontroller

Caught this because Hackaday shared it (post).

Custom Bookmarks and Forgetting Letters

Engraving a bunch of new stamps and it seems I forgot some letters while setting up my files. The name of this font is Anabel and I thought it would make a great set for embossing. It's going to come out with colored letters not the way it shows on the screen.

Heading out to Juniper Library today and making bookmarks. If I get time I'll make an I heart Science stamp.

Organizing my embroidery floss

Today I spent some time organizing my embroidery floss while listening to music. It was pretty relaxing. It's really satisfying to get the first row of the spool nice and even.

Reminder: Monday is Craft Night at HeatSync Labs and you can make your own stamp for free. See details here;

Happy Mother's day and other bookmarks

I hosted some bookmark making workshops at Scottsdale libraries last week.  We used stamps and embossing powder. It's a lot of fun.

Big compact calendar

Today I'm working on an 8 foot tall calendar using the vinyl cutter with a sharpie in place of the pen attachment. The design comes from Dave Seah who made it as a compact calendar that prints on a single page. I'm a fan of his design work and particularly this calendar.

To get it working with the vinyl cutter I used a single line font and saved it as a PDF. This page has great information about single use fonts.

Edited to add a view on the wall for scale.

Red Mountain STEM Expo

I had a fun time yesterday at the Red Mountain High School STEM Expo. We had a bunch of kids soldering this really cool flashy LED white board sign in the shape of an Erlenmeyer flask. I chose this shape for Barbara Torrey the biology teacher who worked really hard to make this event happen.
