Alexa Dot Holder

Alexa Dot Wall Mount

My brother got me an Alexa Dot for Christmas a few years ago. It turns out to be a lot of fun. We put it in the kitchen and the kids play music. My wife and I also use it to add things to our shopping list (very convenient!) Anyway, I like to explore by tying in the names of gadgets I have to see what kinds of modifications you can find. When I typed in Alexa dot I came across this really cool plug holder which would get it off my kitchen counter.

The design is by Cpt Skippy and I am really pleased with how it turned out.

I may post a new picture when I get a smaller USB cable that doesn't need to wrap around so much.

Picture of the switch

We recently moved into a new house and the kids are having fun running around turning on and off all the lights. Unfortunately, some of the light switches are not for lights. One goes to our garbage disposal, another goes to the gas fireplace and another turns off the furnace …

I have been coveting a FarmBot. At $2500 to $4000 these farming robots are a little out of my price range. However, I guess if I had a big enough yard I would still be looking to purchase one of these. They are so cool, they will plant, water, weed …

Intrducing a 3D printer to my daughter's Kindergarten class

Sat 09 May 2015 by Dr. Dirk Colbry

We had fun showing off my 3D printer to the Kindergarten class. Although the printer is fun to watch, kids tend to get board with it in just a few minutes. I like to come up with classroom projects that let the kids use things that are printed with the …

I have been having trouble with my 3D printer over the last couple of months. It turns out that the fans got disconnected. Once I fixed the problem my printer is working better than ever. I was itching for something to print so I came up with this simple spacer …

Ultimaker 2, cleaning a clogged nozzle

Sat 02 May 2015 by Dr. Dirk Colbry

So my Ultimaker2 extruding head got clogged, really bad. Something got jammed while printing and I could not get the filament to feed. This had happened once in the past when I tried using some really cheap filament but I am not sure the real root of the problem this …

April 1st Brownies

Fri 03 April 2015 by Dr. Dirk Colbry

An oldie but a goodie with a modern twist. This year I printed out the letter E on my 3D printer using Brown PLA plastic.

Then I put the Brown E's in a baking pan:

Cover with aluminum foil and tell the kids I made brownies for them.


The were …

3D Cookie Cutter app comparison

Thu 25 December 2014 by Dr. Dirk Colbry

My oldest daughter is in her second year of Brownies. My wife and I volunteered to lead a couple of their meetings with a maker theme. I thought the 3D printer is always a hit and what better project for girl scouts than cookies (yes I realize this is cliche …

I saw my first 3D printer when I was visiting the University of Notre Dame. It was over 10 years ago, it was fairly expensive to operate and it printed in a kind of expensive wax.

Anyway, this was the first time I saw a lithophane. It was a picture …

Snowflake Lithophane

Fri 28 November 2014 by Dr. Dirk Colbry

There is something magical about looking at a lithophane. I like handing them to people with the light coming from the front. Most of the time they are polite and say, "that's nice." Then I have them hold the lithophane to let the light come in from the back and …
