DIY Remote Control for Everyone

[ALBQ]

Moderators,
Would you please move the BasicStamp postings from the “High End Pre Group Design Invitation” thread over to this thread? Fear that suggestion of alternative micro-controller was un-welcome and would like to start fresh with a new thread for those interested.
Thank you -ALBQ

Why don't you just summarize it for us and give a link to the old thread. Those who are interested can follow it up.

p.s. I want an RF remote. So, does ''Remote Control for Everyone" include me?

Summary,
Suggestion was to build a remote controlled preamplifier using a Basic microcontroller such as a BasicStamp, BasicAtom or BasicX microcontroller. Although slower than a PIC or Ubicom, the controller can be programmed in basic using free downloadable software. The advantage of such a solution for the DIY community is that it takes minimal software knowledge to get it working and, can be easily modified at by the end user. This means that once a basic design is developed, people are free to build upon it.

Oh, on your question, was thinking more along the lines of IR remote but, hey - its for everyone so, why not

Cheers -ALBQ

BS2 code and specifications for above:

BS2 source code:
http://mywebpages.comcast.net/gilles...me-Encoder.bs2

Specifications:
* BasicStamp2 micro (will migrate to BasicAtom)
* PGA2310PA - digital volume control (256 step)
* IR - function (power, volume, mute & IO control)
* LCD display - on/off greeting, volume setting, mute, function
* Rotary Encoder volume control
* +/-9V Analog PS w/switching for when unit is off
* +5V-9V Digital power - onboard filter network to wallwort

Still to go:
- Migrate code to BasicAtom - more speed, power & memory
- Add switch inputs - for manual control (74C922)
- Write code for balance control via rotary encoder (mult func)
- Change LCD for VFD
- Final design of power supplies
- Draw and etch PCBs
- Put it in a box

I like it

So this is a neat programmable switchbox and volume control, not an active pre-amp, right? Could I add an active preamp into the mix without too much trouble?

Any idea on what the costs are approximately?

Regards,

Michael

Michael,
Somewhat - with a PGA2310 you could go either way. Leave it as is, would not exactly call it passive or add a stage of your choosing. Total cost as you see it is around $150, maybe a little less.

I was wondering that would u be kind enough to let us know the source of this PCB, and if i m not wrong its based on AT89S8252 an 8051 based AVR?
I too have got almost the same board....

[jleaman]

Im going to be selling these as kit's the pcb comes from a friend in china

[jleaman]

I have many idea's of my own to build a better pre-amp.. Does any one want to work on this and put all there ideas into one pot and make a good pre-amp ?

Id also like to use this LCD..
