Hashtag Test

This is a #test to see if I can insert hashtags into #Blogger posts.

Why can't Blogger just take the Labels I add to a post and make them into hashtags?

Tardis Lights Mostly Wired

Yesternight I was at the Milwaukee Makerspace. I wired up the LEDs for the Tardis I 3D printed a month or so ago. While I was there, I also 3D printed four more white bases for the wobbly chess set.

Last weekend, I bought six ultra-bright white LEDs from Radio Shack.  They will go into the top of the Tardis.  The plans for the Tardis on Thingiverse included a support that will hold four small LEDs.  A fifth LED will go into the top of the Tardis.

I used the circuit shown below that I got from a website that helps design circuits for LEDs.  (See this blog post for details about the circuit design.  Also, here is a link to the circuit below on Digikey's SchemeIt tool.)

I got the resistors, some wire, and a 9v battery plug at the Makerspace.  Below are some pictures of the soldered together LEDs both outside of the Tardis and then installed inside it.  I still have to wire in a switch that will attach to a special pieces in the bottom of the Tardis.  My son thinks I should put some kind of pushbutton switch on the top of the Tardis.  I'll have to look into that.  Finally, one of the windows for the Tardis are no longer in my locker.  I'll have to print another one.  Then, I can assemble the lights into the Tardis.

Printed Some Wobbly Chess Bases

I made it back to the Makerspace after a few weeks off.  Tonight, I took a spool of white PLA filament and printed five (5) bases for the wobbly chess pieces.  This took about 2.5 hours and was all the time I had tonight.

I'll take the pieces home and glue them to the top pieces that I printed before.  I need to figure out a good weight to put in the base to make them stand up.  The Thingiverse instructions says to put in five pennies.  I'm going to try lead from Pinewood Derby cars.
