Anyway even thought the site has been down, i have not. I’ve been working quite a bit (real job), but . . . → Read More: Update !

My site was down for like a month, sorry

Hello everyone. Sorry I got caught up with work and my server started clicking. I actually moved and changed jobs so I didnt have time to fix my server. I finally fixed it up and here it is again. I think I’ll be moving all the “robot” stuff to a web host as I am trying . . . → Read More: My site was down for like a month, sorry

Simple Version is running !

btbot running on youtubebluebot running on youtube

With a 330pf cap and diode to power the circuit when both motors turned on, and more diodes and pull ups etc the circuit worked 10x better. This time instead of running the power through the mcu circuit I just connected ground and tx from the blue tooth module to . . . → Read More: Simple Version is running !

Current Circuit

I had some issues with the first circuit (right) so now I’m building another. I was using 403 diodes and such that were just too small to work with on these boards. I got some newer diodes and revised my circuit to account for most “bad stuff” Now I’m trying to make it nice stable and . . . → Read More: Current Circuit

We are nothing but the cumulative experiences we experience during our life

I’ve been meaning to write this for a long time. I think that people are all born almost exactly the same. The only difference between them is who their parents are and what their genetic makeup is. I’m including defects and handicaps as attributed to genetic makeup.Your parents are responsible for your genetic makeup but not . . . → Read More: We are nothing but the cumulative experiences we experience during our life

Laser cut parts went together great !

I was expecting something to be really wrong, I was expecting that I had overlooked something, but suprisingly everything worked great. I can even make 2 more models when I have time.

Overcoming gridview limitations, switching the screen around.

Gridview is great but it does not allow you a lot of functionality. As with most things from changing to higher api sort of things you loose the bottom up functionality. In my case gridview does not allow you to actually set on touch listener and get the position easily at the same time. So you . . . → Read More: Overcoming gridview limitations, switching the screen around.

Goodbye button class, hello gridview.

Upon trying to make my console “half” the screens width I realized that the “absolute” layout is a can of worms. With absolute layout you have to define the exact x,y of everything so, when you change screen your going to have a distorted mess. You would have to make a different layout for every android . . . → Read More: Goodbye button class, hello gridview.
