Lynx Wireless DMX / Re: Obsolete parts that are no longer availible at Mouser

It appears that Microchip recently came out with a new module,  "MRF24J40MD"   that on the surface appears to be a drop in replacement...   with stronger output and more sensitive receiving...    from Microchip on a onzy basis,   $15 each...  (over 4000 currently in stock).    The bad is that that chip is not yet available at Mouser.    Whether it truly is a drop in requires the boss to pitch in with his esteemed expertise.

Recommend you pull (reference your photograph)  the 6n137 optocoupler chip on the right and re-seat.    it does not appear to be making proper contact.     (this may or may not fix your immediate problem but definitely would affect output).

It does look like the discoloration that often occurs in the bathroom tub sealant.   I would suspect microscopic bubbles of air or moisture trapped in the sealant.

My computer was reporting that the file did not have a digital signature to validate it.   I had to go around the system to get it installed.

It took a while, but finally got the hardware in place.    A short daytime video attached.     Still want to adjust the firmware.   For now, the circuit is set up so that it comes on with the landscape lighting.   easy to change over to a 27/7 lighting display.    Very visible from the street.    Uses a 12 volt power supply from a printer to get 12v DC for the SSC and the SCC test firmware.

From the picture, the bottom two resistors look wuestionable and specially the bottom one.  Did you do a resistant and voltage check on them?

The Porch / Re: LED strip mounting ideas
« on: August 29, 2014, 06:29:01 am »
One simple idea is to screw a hook into eve above the place you want the strip to hang.   Attach the strip with fishing line and use Velcro patches to "attach" the strip to the wall.   This life of this method would be dependent on the humidity level  -  high humidity, not very long life.

The original transceiver (version 1)  used the MA chip {in both the RX receiver and TX/RX transceiver).    In the transceiver version 2, RJ jumped to the MB chip in the transceiver because it has a stronger broadcast signal and did not require an external antenna.   

Real Components  indicates they have a bunch (over 3000 in stock)   but price unknown.    You'd need to call them.    You are not allowed to view links. Register or Login

Rethinking the power.   Attempting to use landscape pwr supply is definitely more convoluted than anticipated.  Found packaged 4 and 6 amp 12 volt regulated supplys (less than $10)..  current thought is contain in small water proof box hidden under under rock next to display.  scc could alsso be in box and wire distance between scc to first node should be less than 36".  Wall outlet controlled by switch that has dusk to dawn programming built in. (With options).   Getting closer

While most landscape lighting doesn't really care if the voltage is AC or DC, the SSC does so you may want to look for a high output regulated DC supply instead of a landscape transformer.  You could also build yourself some filtered and regulated rectifier circuits that you could put into the poles that would convert the AC to regulated DC for the SSC's and let the rest of the lights run on the AC voltage.
Would adding a simple rectifjier/filter onto the circuit just prior to the SCC be enough?  Only need enough juice to drive the one string of led lights.

It looks great up to the landscape power supply.  Those are unregulated 12 VAC supplies and the SSC requires a regulated 12 VDC supply.
Suggestions?   (and thanks for the caution)   This power supply will eventually all be supplying power for regular landscape lighting along the flower bed / sidewalk.)

Could be pretty cool, with 128 nodes it will be BRIGHT.  Do you have any heat worries there?

Won't know until I try it but with the LEDs, I should be pretty good.    I had originally stuffed 400 small incan lights in it for last Christmas but the high humidity here this spring and summer  has severely limited the electrons flow through the corrosion  so you can almost make out the lights through the globe.    I'll be doing Corrosion X on the lights (before stuffing) and the circuit board as part of the assembly process.
