Reviving dead brain cells with electronics …. November 16, 2013. Having been busy for the past several months, I’m just now able to refocus on all of my projects, including the POV Poi one that’s been sitting idling. Every day I stare at the two batons, yearning for me to pick them up and do some work. Alas, the time has finally come. So I thought, why not make a permanent development board? Micro SD card reader. All of a sudden, using the 32U4 became impossible. Enter the new AT91SAM3X ARM series! It al...

Code Freeze! | KA4 Designs

Reviving dead brain cells with electronics …. August 7, 2013. Will remain there for the next revision. There’s just too much to be working on right now and I continue to push the project further back because of that. No more! So, with that said, here’s where the project stands:. Four strips of 48 full color LEDs arranged in a square tube shape, inside of a round polycarbonate tube. Final tube length will be somewhere around 18″, though we are diligently working to make that shorter by an inch or two.

Reviving dead brain cells with electronics …. August 1, 2013. I used to be a “list” writer, do this, do that, remember this, get that … But then you ask, when is it too much? I know people who write lists about lists. That, to me is overkill. When you get to the point of needing a list just to keep track of your other lists, you’ve got a problem. Plan for a thicker PCB. 8211; Done, 7/31. Check height on LED. 8211; Done, 7/31. Move control board to wedge inside of LEDs boards. 8211; See above, 7/30. Add b...

Reviving dead brain cells with electronics …. Hacking a Reflow Oven. July 15, 2014. After spending the last three years building small circuits here and there and doing so using the skillet reflow method, I decided it was time to step up my game and bought one of those cheap, Chinese reflow ovens: a T-962. After cooling, I tore the oven open again in preparation to perform a hack as explained by this awesome instructable. What’s up with that? It took me a little over an hour to get the hot glue removed j...

Reviving dead brain cells with electronics …. December 10, 2013. In the process of cleaning up and organizing my office, which also functions as my development and coding area, I came across several bits and pieces of past and present projects. Some of which I forgot what they are or why I made them, at least till I went back to the original schematic to try to decipher what I was doing. A couple of things became obvious:. I have a lot of components and parts! 8217; That’s certainly an option, espe...

Capture Time | KA4 Designs

Reviving dead brain cells with electronics …. July 30, 2013. I decided to cobble together one baton. A couple of things were immediately obvious:. A pain trying to solder *inside* of a square tube. Thin PCB warp too much. Small pads coupled with thin traces tend to break or lift off of the PCB very easy. Need to find a better way to interconnect the PCBs, both while daisy chaining, as well as sideways to its neighbor. Other things that became apparent after I started playing with it:. Tags : POV Poi.
