I need to hire one person who will be able to make a small program for pic 12F629 (or to modify an existing one). It's a remote controller/timer via radio (433 MHz or 866 MHz). I have the exact requirements.
I'll need the program, in order to put it inside of this pic (why I need to use 12F629?: because I bought a lot!, and because the program will be small enough to fit into this one).
All of you interested can drop me a line to: email@example.com

Hello again (sorry, I'm a newbye, and I can't post PM to the rest of you),
and specially for Wizpic and mEiNaRd, who had written me:
The requirements are:
-Do you know the Velleman kits K8057 and K8059?. Well, this project is based around this one. The Velleman is a simple 2 channel remote controller, and you can program any of its 2 channels to any of 6...8 choices (I mean: you push one button in the remote, which is like a door opener, and you have timing durations from 0,5 seconds-5 seconds-15 seconds...and up to 60 seconds, and even flip-flop...except if you keep pushing the remote button all the time; in such case, the receiver will maintain the "on" state until you release the remote button; and I mean in the 0,5 second timer mode; it's like a push-on-pull-off mode). You can push any of the 2 buttons on the keyfob remote, and it has both pulse or burst modes. Of course, the previous example was done with the remote adjusted in continuous or "burst" mode; in pulse mode (pulse duration: aprox. 1 sec.) you're not able to do this.
The question is the Velleman is perfect, but I need minor changes:
-I need that the led in the remote controller remains lit until you change of state (I mean, in long timed periods). I know: I'll employ more battery energy, but this is the requirement! (the Velleman uses the typical 12 volt battery, normally used in any door opener).
-The Velleman use a very simple design, and it uses a Radiotronix module as a receiver (433 MHz). I'll prefer a better, more reliable module, like another Radiotronix, but superheterodyne, quartz stabilized...all in all, more reliable (to install it inside a truck, and avoiding spureous, etc.).
-It uses a vinculation mode which claims to have "...more than 1.000.000.000 combinations". It works vinculating both the transmitter and receiver only once at the beginning; it generates a random code, which can be returned to a "factory default" state.
-In the future, maybe I'll need a third button, but not for now.
-The receiver uses a very simple design topology: the receiver module, the data from the receiver goes to the 12F629 data in, and the two PIC outputs going directly to the base of a couple of BC547 transistors, triggering a 12 volt relay each one (the circuit employs a small 5 volt regulator for the rest).
The main goal here (almost for me) is the "silly" thing of the led; nothing silly!. It must indicate me the "change of state" of the receiver in the transmitter! (I like blue leds
), and only in channel one; channel two can be as ever: you push, and you have light; you unpush, and the led goes off. I don't know if the Velleman uses KeeLoq or not, but I'm sure that it doesn't use DIP switches (I don't like DIP switches; I prefer the method described here, as the Velleman uses).
You can visit the Velleman page here:www.velleman.be
and the exact kits are (receiver):http://www.velleman.be/product/view/?lang=en&id=352724
We will stay in contact. I'll remember my email, because I cannot reply private messages yet:firstname.lastname@example.org
For designing costs, fees, payment method, etc., drop me a line with your requirements, please. If you have a similar, or even a bit more complex project done before which can be useful, it will be valid also.
Thanks a lot for your feedback! And sorry: I'm in a hurry at this moment!.
