Hi,
I keep reading hints that it is possible to turn this remote into full learning mode by adding the components that are missing, but I have not been able to find full schematics on the subject.
Has anyone been able to do this? If so, can someone please post schematics/how tos?
Thanks

These are pretty new remotes. You need to find somebody with a learning variant to open it up and take pictures of the PCB and then compare it with yours and add the missing bits. I have not seen such a photo on this forum yet.

If you send me pictures of your PCB, I'll see if I can help you.

OK. I will be out of town for about a week, but right after I will get on it. I'm pretty skilled at soldering so it will be neat to be the first one to do it, I guess.

Cheaper to buy the learning one if becomes available.....

I looked at this for my Atlas JP1.2 1025 using the JP1.3 3000 learner as reference but never bothered to look for the components.
Code: Select all
JP1.3 JP1.2 JP1.2
3000 1025 8820 Schematic
J1 =0 000 J4 LRN Enable.
R13=105 R31 1M
R12=102 R32 1K
Q3 =1AM Q31 MMBT3904 first transistor
C7 = C32 10pF
R14=103 R35 10K
R18=102 R33 1K
C18= C33 10pF
Q4 =1AM Q32 MMBT3904 middle transistor
R23=102 R34 1K
Q5 =1AM Q33 MMBT3904 last transistor in learning circuit
R20=103 R36 10K
R24=103 103 R37 10K
C6= C31 0.1uF
R3 =101 R38 100ohm R3 labelled R1 on JP1.3
R35=115 103 10K
R5 =1R0 2R2

Success! I had to place an order from an electronics supplier, anyway, so I added the necessary components to my order. It came in today, and I soldered te components in. It worked perfectly. Instead of a backlit, NON-learning Atlas, I now have a learning function as well.

it would be great if you could provide pictures and an estimated cost
This is great news for those of us who have Atlas' and don't have learning!

OK, I will get pics tonight. I was so excited to try it that I put it together before taking any!

I can confirm this info is valid also for the Atlas OCAP 1056.
I managed to convert mine into a learning one for a few bucks...
Code: Select all
Part Desc Digikey p/n
J10 0 ohm
R12,R18,R23 1k 1/8w P1.0KACT-ND
R14,R20 10k 1/8w P10KACT-ND
R13 1M 1/8w P1.0MACT-ND
C7,C18 10pF 399-1108-1-ND
C6 0.1uF 399-1167-1-ND
Q3,Q4,Q5 MMBT3904 MMBT3904FSCT-ND
Some of these parts might be salvaged from old video cards, I did not order the 0 ohms resistor, since I reused one that way.
Beware that it takes good soldering skills for such a project. At 6$ a piece, he's surely not making much $$$ doing them...

I just did this to my JP1.2 1055 and it works as well. The only thing was I could not find a J4 or J10 anywhere on the board, it only has J1 which was already jumpered on mine. I also did not install any of the capacitors since I don't have a LCR meter and I was stealing components from dead equipment

Did someone post schematics on where these items need to be soldered, etc. I need a mini project for myself and plan on picking up a couple Atlas OCAP 1056 off of ebay along with a USB JP1.2/.3 cable from Tommy.

When you open it up the component locations are all silk-screened so all you need to do is plop the parts listed above in the right spots.
