Do you have a bike trip computer that makes you enter a 4 digit number when you power it up?
Does that number correspond to the number of mm circumference your bike tire is?
Did you also loose the manual like I did?
Well, you're in luck then.
I got a different road bike for this year, and the tires are clearly a different size than my Mountain Bike's. What that meant was I'll need to remember a new number for when my trip computer battery dies. But what's that number in the first place?
For my trip computer (A Generic Schwinn one) I found an online scanned version of a similar manual. That manual gave my bikes wheels (28.0" Dia.) a nominal circumference of 2237mm per rotation.

Double check those DRC's
I have some good news, and some bad news.
First,
The PCB's have been made and are on their way here! Which has me pretty excited.
Next, the new version of the LED cube controller looks like it will be a sinch to use. Also on that the order for a bulk bag of 1000 Blue LEDs has been made. Meaning I'll have boards and LEDs in a couple of weeks. Next I have to get the lead out on ordering all the components.
Then, there was -minor- bad news. I was putting together a BOM for all of the parts. Just adding on values to things that I know I didn't add to yet. I noticed an overlap of 2 parts on the board. There is a current limiting resistor underneath a hole for the USB port. Means when get that board there will be metal connecting it to ground. Unless I manually Isolate it. Luckily I guess(?) the circuit is just for the power LED. So if I ignore it altogether and just roll with no power LED (just the confirmation Ding in windows when you plug it in) that should be fine for now. Everything else looks fantastic I think.
On the LED Cube Visualizations front:
Some new (soon hopefully) visualizations in the pipeline include:
The Snake Game so far has been somewhat tricky to implement. I dunno why I think it should be easy. Maybe its the 3D messing with me.
Thats where we are at right now, soon with the PCBs here I'll order components (takes a Day). Then the firmware and software is more or less done. Just tweaking. On top of that there will be a new version of the LED designer specifically for 8x8x8 grids when I get those parts working. I want to focus on creating a nice clean cube first. Because the last one worked, this next one I want to look fantastic.
That's all for now.

- Random Walking Points / Structures
- Beizer Curves/Loops Animation
- Conways Game of Life (Edit: "works")
