I have figured out Walter's trailer...

Well as we all know, the basic drive system of Walter is now done and the whole family has taken turns riding it... Now I am on to trying to figure out what I want it to look like, do and all the features. One issue I have run into, is the dual-purpose nature of this bot. What I mean is that I really dig the fact it is powerful enough to move people around but I also want a nice, big deck for a lot of circuit boards, an arm, sensors, a proper head and batteries. Now, of course the trailer idea was thrown out...

Can a Picaxe "Read" Servo Outputs?

So I am playing with a RF radio control system. For one instance, it is a perfect set-up just to have a pot stuck on to a servo (all the outputs on the receiver are servo outputs) and the pot data to be fed into an ADC on my picaxe. Now, seeing that I have a total of 8 channels on the RC unit, 8 individual servos, 8 pots and 8 ADC inputs is just not feasable.

Question:

Ever sampled audio and stuck it on an EEPROM?

Has anyone sampled any kind of audio and was able to stick it on an EEPROM? If so, how was it done? Did it work and how complex of audio were you able to use? There has to be a sampling rate involved here so maybe just some of that 8-bit Super Mario Bros. stuff, right? Gimme what ever ya got!  --Oh yeah, what about playback, as well....

$60 Picaxe Oscilloscope!

I just saw this on Instructables...

How 'bout a serial (or USB) 2 channel oscilloscope for 60 bucks that uses a Picaxe 28x for it's base? Oh yeah!

--The guy even sells the PCB for $25!

Link HERE, yo!

 

USB to Serial Adapters

I am looking at new laptops and it seems laptops with serial ports are a dying breed... I know that Picaxe sells a download cable in USB form but I think I might be getting into i2c programming, that peek and poke thing etc. --All the stuff you need an ol' fashoned serial port for.

Question:

Has anyone ever used or tried a USB to serial adapter? They are as cheap as $6 on ebay but I have no idea if the programming editor or any other serial based software will work with it or even recognise it. Does anyone have any thoughts?

Help pre-programming an EEPROM

I know you 1's and 0's guys are going to throw a bunch of stuff over my head but...

Is there anyway to pre-program variables into an EEPROM (directly from the computer) to be read by the Picaxe later? --Let's say I want to stick in a string of variables that will sorta translate into a map that the picaxe will later follow. Right now the only experience I have had with EEPROM's, as you know, is sticking data into them from the Picaxe. Any thoughts?

 

Add Your Translation...

So we are an international website but we only speak English! Now I know this is the easiest and probably the only way it would work, but is this the only way?

On this thread, I invite us all to pick a robot sorta thing (word, phrase etc) and give us the translation in your native language. Points are awarded for creativity!

So the more I am working with picaxe products the more I am finding limitations to their boards...

Help with Schottky Diode

 

Just don't want to screw this up...

Which is correct? A or B?

Help with the HPWM command

Well, with my new motor controller parts soon in the mail, I am playing with the HPWM command on a 28x...

I am just plain lost, yo. I have re-read the picaxe manual about 40 times now, including the HPWM command and the HPWMDUTY command and am getting nowhere!

I have everything hooked up to a L293D -A,B hooked up to one side and C,D to the other. I can get the motors to spin and have had success in controlling their speed, but they are both stuck in one direction.
