Let's Make Robots!

Birthday Tattoo!!

Well folks,

I just had the 33rd aniversary of my birth and as a gift, my wife gave me 3 more seasons of MacGyver for the DVD collection but more importantly, TATTOOS!!! Yup, a big phat gift cert.!!!! Now, why would I post this news on a geek website like this one? Well, I am going to finally get my wings. Wings of wax on my upper back to remind me of the past times I flew too close to the sun and not to again. Now I needed a roundish symbol to go in the middle and pondered what to do for a while now... I have decided (here comes the geek part)...

28x2 Board --Your Wish List

Well, with all this Walter work going on, I find myself sorta longing for a small, fun tabletop robot --just to play with. I was looking at the standard picaxe 28x board and again, I remember how much it really sucks. No EEPROM space, ADC's have the data pin in the center, no HPWM output to the motor driver etc. etc. I know I have asked this in the past, but my PCB designing skills have gotten a lot better sense then. So, I ask again...

What pisses you off about the current 28x picaxe board and what would you want if you could have anything?

Note:

Embed Audio Signals?

So I got this nifty iPod plugged into Walter and I can easily control it with serial commands. If I were to want to sync say, movements of the head to the audio being played, I now can only do it manually... I.e. I would actually use a stopwatch and time when I would want each move to start/ continue and add the needed pauses to the code.

With the help of ezekiel181, I have finished my new on-board chargers. I just have to say this is simply the best, most adaptable charger circuit I have ever … Read more

A new sexy mobile phone...

Kari and I have been with Verizon for almost 10 years now and during that time, every 2 years, we get a new, free, nifty phone when we re-up our contract. Now, each and every time I am truly amazed how much cooler my new phone is and how much my old one sucked. Once again, this has happened. I just got a new Envy touch and well... MAN! I mean, really --holy crap!

 What you will find below is FROM A FRIGGIN' CELL PHONE!! (It has a macro function!)

Can you believe the quality?!?!

Sharps, Sonar and a dead horse...

This is a dead horse, but...

Again, I am still sick of my sharp sensors. I am looking at  the LV-Max-Sonar(s) EZ(x) sensors as an upgrade... These are the "single-eye" sorta sonar sensors.

Open Question:

Has anyone played with these? Plus and minus for the output options (serial, an., pulse)? Is there clean data?  Etc. Etc.

Gimmie what you got.

Line follow sensor spacing ??

I am a bit embarassed to be asking this but... With everything I have done with Walter, I have never played with a line-follow set up. Now, the electronics I have down solid but I am a little fuzzy on the theory of opperation. I intend to use 4 sensors. Where do they go?

 

How to click a relay with a low signal?

I need to click a relay when a signal goes low. I have a couple relays on Walter, but they all click when signal goes high. These are pretty straight-forward, just a simple 5v relay, and a 2n222 NPN transistor to click it when a data-level signal goes high. --No Problem

Little circuit help with volt reg.

I am using designing a new PCB for a tidy way of connecting all my 5v doo-dads. It is a pretty basic set-up, 5v- 3a low dropout reg, the obvious caps and some nifty screw terminals. This is all pretty straight forward. Now I also need 3v to replace the (2) AA's in walter's mini ampified speakers. Would it be cool to just use a resistor bridge on this same 5v regulator board to get my 3v?

IF / OR Interrupt? Picaxe...

Hey guys,

I am playing with a 40x2 and the hintsetup and hserinsetup commands also with the flags commands... I would like to interrupt on either a hint signal OR a hserin input NOT both at the same time. It seems that with the various flags conditions, you can stack-up a bunch of stuff that has to be true to interrupt, but there is no "OR" --just a bunch of ANDS

 

Basically, "if hint1=1 and hint2=1 then inturrupt" but not "if hint1=1 OR hint2=1 then interrupt"...
