I have been busy with 4 different projects, one done and the rest coming along. I seem to bounce back and forth as I ponder over some design flaws and possible solutions. Which usually leads to a “hey let’s do this too” moment, I like to call it my Shiny Penny Syndrome. It works for me.

We need a bluetooth speaker for the outside by the pool and I have also wanted one to use inside the house as well. This one is 90% complete. I still need to find what I am going to use for front and back grills. I may settle for some black material on a frame for the front and some aluminum grill for the back. In the meantime at least it is ready to go!
While the Volumio is up and working in the family room downstairs, I am still working on the case for the setup. I have the idea firmly in my head. I have the case hollowed out. I need to find a way to get down to the bottom and clean and smooth the bottom. it is too small to work it with any chisel I have. I was thinking of upping the RPMs on my drill press and using the drill bit to clean it out. We’ll see, I still have a little research to do on this one.
Arduino CNC experiment
My goal here is to have a larger CNC mill, a real one, that can handle wood and soft metal like Al and brass. While I usually like to jump into a project with both feet, I have learned and bit by over enthusiasm in the past. I have read quite a few builds using old DVD drives, the LM293, and an Arduino to make a simple X / Y potter (the Z axis raises and lowers the pencil). I have the X axis works, the Z axis servo works when it feels like it (so much for the cheap micro servos in the intro kit. Time to scavenge from an old RC car tonight). The Y axis just grinds at me, so I need to dig into it here tonight and get it moving, literally.
This is one that was downloaded, installed, configured, setup with 2 controllers, an old LCD monitor, and it has been hard to find to time to play with it myself. That is OK it is being well used. I have an audio DAC for the Pi 3 some old monitor speaks to mate with it. I have been searching for a case idea. The cases one can purchase are well – so so, do in a pinch, rather not spend money on one, will the HAT fit? As I pondered and searched, I stumbled upon an old Game Cube for sale on eBay (9 bucks right now, don’t bid on it please) and it looks like it will do the trick quite nicely. Integrated power supply, spaces for controllers / USB ports, and about the right size. I hesitated when I click on bidding for it, but as time goes and I read some, it should work quite nicely. Stay tuned for where this one ends up.
Since the RetroPie is up and going, I have been playing some Tempest, my ALL time favorite arcade game; but it just isn’t right playing it with a controller, keyboard, or mouse. One really must have a spinner for the real experience. I have looked for them online, but they are rather pricey (upwards of $70.00) so I have been looking into making my own. I have the box of parts and my notes in line. I will find some time one night when nothing else interests me 😉 I guess you will just have to check back on this one to see how it goes.
