noob seraching for best microcontroller

simply put i'm trying to figure out witch microcontroller would be best for my purposes. the things i need are 3 pwm pins, 2 normal io pins, as well as what ever else i need pin-wise to controll a nrf24l01+ transceiver

i'm also trying to keep this as light as posible, as its gonna be the rx side of a tiny rc airplane, just under 6in wingspan p-38 lightning . i figure one pwm for the pager motors, and one each for the aleron coils and the two normal pins for current direction, though if needed i could use a spring and the coils to skip the other two pins.

Project Reprap Rostock Rosblog (Hopefully not ROSFLOP!)

Thought I would start a blog documenting my rostock build. Hopefully this will help some other noobs work out the minutae of a project involving so many disciplines!

I wish to make complex project X with W, Y and Z features. How do I do it?

WARNING: This project is only a mock-up project intended to help convey to the proper perception of how difficult or reasonable some random project X might be to take on. My target audience for this post is mostly impressionable, clueless youths (and I mean no disrespect), also people lacking method, common sense and/or social convention might benefit from it.

Continuous servo with picbasic

If you have 2 servos that you use to propell your robot, chances are that one of them are inverted from the other one.

This is a bit of code i use so i only have to set the speed at one place(bot_speed) and this does the rest

This code is not tested yet, but it should work pretty much as it is.

My servos range from 100 to 200 so this example is based on that.100 spins the left wheel forward and 200 spins the right wheel forward.



I found this 40-pin chip in a CPU battery. It is labeled PIC16C74B-04/P. I have the datasheet, but that's not my best language. i just want to know if its possible to use this as the ones used in LMR - if is possible to make a robot with this chip and what would i need to program it. I read something about ICSP(in-circuit serial programming), which I believe is the process used with this chip, but that's as far as I go. Thanks.

how does XORF work?

howd yu do?

I finaly caught on to the PIC assebly language!

I am using a pic on a simple little robot with the usual bump, revese, turn, obsticle avoidance. it will do more than that later but I havent even writen a PIC program yet so I am starting small. anyway there is on thing I don't understand in the tutorial i read. it is the XORFcommand. I understand xor gates but how does it work here; http://www.pictutorial.net/?page_id=152

Which motherboard (basic stamp?) to choose

hello me and some friends are making a robot, and i would like to know which motherboard(basic stamp?) to choose. i need something above average to put several kinds of sensors and stuff on it. any ideas?

thanx in advance:)

Help? Programming PICAXE?

I'm sorry if i sound like an idiot, but...
i have: picaxe 28 starter pack
1 motor
1 hitec hs-325 servo
a laptop and the programming editor for picaxe
im sorry if this is really annoying and its too similar to the start here link, but i need HELP!!! 
for some reason i cannot program the 28...
This is a robot I am working on to create art, I hacked an old RC car, but instead of hacking the car, i hacked the remote (the leftovers of which are on the hood … Read more

Not to take users off this site but updating two postings of this is getting tiring. From now on you can find info about this project here. I will leave the funny video up.
