I finally finished a design that replaces the two LEDs in a Neuros Recorder-2+ (Green for plugged-in, Red for recording) with a single LED that turns Green when it's plugged in (powered), Blue when the unit is turned on, and Red when it's recording.  In addition to the onboard 3.3V, this design also uses +5V from the DC power supply allowing well over 20mA to the LED (design is actually capable of 100+ mA).  Combined with widely available LEDs that produce 6000 - 8000+ mcd (sometimes called ultrabright LEDs) lack of brightness outdoors should not be an issue.  Potentiometers are also included to allow a wide range of brightness for each color.  The DIY document can be found here:

Thanks everyone for the kind words and to those who emailed me to buy one or ask for more information.  I updated the DIY manual to include additional installation and operational details.  It's the same link as before.  For those handy with a soldering iron and can deal with SMT parts, a complete BOM at cost is $10 plus ~$5 to box and ship it to lower 48 states.  Given some spare time, I'll assemble and test a unit for an extra $10.

I'm not sure how I'm going to do it right now..  But I'm going to try and make this hack a remote.  I'm putting this unit on a sportbike and would like to but the leds on the "dash" while the unit will be affixed near the rear.  hmmm

Moving the LED to a remote location is easy by running wires from the board to the LED instead of soldering the LED directly to the board.  I don't know how to "wire" the remote part.

BTW - I assembled 10 of these in my spare time this weekend and will sell/ship them at cost, $15 each, to the lower 48 states until they're gone.  Then it's back to unassembled units.

Forgot to add - got mine the other week, very cool, very nice kit! Now I have to catch up with my electrical guru for installation -  don't trust myself for this one! Wink

Thanks!

Since receiving far more requests for assembled RGB Boards over unassembled RGB LED kits, I designed another version, had 100 units built, assembled, and tested by a company with very reasonable prices, PCBGeek a.k.a. Univelop Tech LLC.  This version is easier to install since there is no longer a voltage reference potentiometer (adjustment) and the three brightness potentiometers were reduced to just one potentiometer.  LED voltage source selection is still set using a standard jumper and LED current limit protection was added using a standard jumper.  No more worries about soldering SMT devices, the RGB Board comes fully assembled and tested.  Because of the simpler design and competitive PCBGeek prices, the price is the same as the previous unassembled kit version, $15 shipped to lower 48 states. Below is a link to the installation manual, a picture of an RGB Board (PCB v20C) standalone and installed in a Neuros Recorder-2 Plus, and pictures of a modified Neuros Recorder-2 Plus in each of the 3 states.

Manual (PCB v20C)




                     Plugged-In                                             Turned-On                                            Recording


Update:  24 May 2008
This modification has been tested to work on both the Neuros Recorder-2 (P/N: 4030200) and Recorder-2+ (P/N: 4030500).  The manual has been updated.

Update:  28 May 2008
You're welcome Tango_Au.  I assume you're down under?  Sold a few there already.

Update:  07 June 2008
For those who wish to have the RGB Board shipped with the LED unattached, the manual has been updated to show LED pinout and schematic.

Update:  09 August 2008
The manual has been updated to include RGB Board Stand-Alone Test Procedures.

Update:  14 September 2008
The manual has been updated to include arbitrary color assignments to Recorder-2 functions.
