Hi Chris,
I see the thread has been resurrected is there perchance a schematic of the circuit in existance, PDF, Jpg, etc ?? so I could happily build a one off

I got ready to program it into a PIC and put it in a ss8 not as portable but should have worked. then I realized it was for an 1825 not a 688 when the assembler gave me an error.
Everything is in the download. It was created in Kicad(which is free) so you should be able to load it up and get whatever you need from it. Let me know if you have any problems.
If you do get a 1825 it will work in an ss8. I actually did this last year for a pumpkin patch at my Mom's house. I changed the output sequence, put in a 1825 and connected the cat5 out directly to the cat5 in. Voila...a self running controller to make the pumpkins shimmer.
For the output sequence, do you have any instructions on how to modify it an what the different values are used for?
Hi Chris,
Many thanks, Success after "jumping through a few hoops" in an "unfamiliar" program, that circuit certainly looks do-able on my "favourite" stripboard. I will now figure out wether to go ahead immediately or get through my season prep first :-( time is running out!!
On a cursory glance that Cad program looks very nice - more investigation of it to follow
Cheers,
Terry
Here's what I use. It's only a rough plugin but it does what I need it to do.
Extract the .dll file and put it in your output plugins folder. Create a new sequence of 8 channels and set the RenTester as the output plugin for those channels. You'll want to keep the sequence pretty short. I'd start with around 10-15 seconds. Do whatever sequencing you want to do and when you're finished run the sequence. When it's done you'll be presented with a box. Copy the contents to the clipboard. This is the data table that will go at the end of the .asm file.
Open the asm file in MPLAB and scroll to the bottom. Replace the current table(starts with dt) with the contents of the clipboard. Save, compile, etc.
Please note that the way the Rentester works is it repeats each set of 8 channel values multiple times depending on the count settings in the code. If you have any questions let me know.
I'm just curious if a Rentester ever officially became available. I don't remember the details but I remember that I more or less stopped working on it because others were putting out a similar board.
The only reason I ask is because I still use this every year to work out kinks and honestly, I consider it as must have tool in the toolbox. I'm actually about to build a couple more(yes, I use it enough that I can use more) and I'm thinking on 3d printing the case. Nothing in the works at this point but I don't think it will be too much work to make the design.
Is this what you're looking for??? The Renard Plus guys may have a couple of these leftover, I dunno....
