3D Printing for Fun and Homebrewing

I recently picked up a mini 3D printer made by M3D.com because I wanted to channel my inner-maker and see what it was like to dabble in 3D printing, but I didn’t want to spend the $1k-$2k or more for trying out something that I might not like.

This particular printer has a capability of printing objects up to 5.9″ x 5.9″ x 5.9″ in both PLA and ABS.  It is not the fastest printer out there, but with a little patience and sub $400 prices, I was willing to give it a try.

After unpacking the printer and settling on the white filament for my first dive into 3D printing, I looked for something that was simple, small, and easy to print.  I picked a flop-eared bunny for one of my daughters for Easter.  I pulled this 3D model from a well-stocked source of 3D models called Thingiverse.

It was easy to get the printer up-n-running.  Here is a sequence of photos during the 4-hour process with the final image being the bunny with all raft and supports removed.

Now that I got thru my first successful 3D print.  I started thinking more of what can I print that might be practical and useful?  I know I have always wanted something to keep my charging cords from falling behind a desk or nightstand, so you can print these:

And how about a nice custom case for that new Raspberry Pi you recently got?  Or custom printing some other little project box?

There are many helpful projects you can print that already exist on the Internet and many colors to choose from.  Want to strike out on your own and brew your own custom widget?  Here is a chance to learn 3D modeling and there a quite a few freeware versions of software to choose from.   I recommend going to a site like 3D Printing for Beginners for starters.  There appears to be quite a bit of info on this site to keep you busy in learning about 3D printing.

VK0EK Heard Island DXpedition is active now!

VK0EK Heard Island DXpeditionVK0EK DXpedition – March 6 – April 20, 2016

DURING the FT4JA DXpedition (March 29th – April 11th)

Because we will be on the air at the same time as the FT4JA DXpedition – and because we will both be operating from a very similar time zone – it is very important that we coordinate with the French Team, and we have. We will use different frequencies for RTTY to allow a greater listening range until FT4JA comes on the air.  We may occasionally deviate from this plan before FT4JA comes on the air, if the op considers it useful to do so. We also will make sure we are on valid and legal frequencies for 80M SSB.

Check out the website for the VK0EK Heard Island DXpedition. They have some great tools on their website to help folks who are trying to work them.

Becoming A Great Elmer

There is much being said and written these days about the importance of bringing new people, especially young people, into our Hobby. There are many obvious reasons for this. As we all get older or get busy with other aspects of our lives, some will leave the hobby. Also, we have the use of many commercially valuable portions of the RF spectrum and there is always pressure to reallocate bands or segments of bands which are not fully utilized.In my mind, the most important reason to bring new HAMs into our hobby has to do with the energy and new ideas that these folks bring to Amateur Radio. Amateur Radio has always been a learning hobby and new folks help us to keep this important part of what makes our hobby so much fun vibrant.

Anita (AB1QB) and I try to put a lot of time and energy into getting folks started in Amateur Radio and helping them to build their skills and progress. Our Amateur Radio License Classes and the youth outreach work that we’ve been doing are two good examples of this. To make these efforts as successful as they can be, it’s also very important to provide good opportunities for folks who are new to various aspects of Amateur Radio to learn and gain experience. This means becoming an “Elmer” or a HAM Radio mentor to people who are less experienced in some part of the hobby than you are….
