Hello All! Can you guys help me figure out how to get my situation sorted out. It is very similar to what you are talking about in this thread but I am kind of lost. I posted this over on the Avs forums also but no real help was given as of yet.
Here we go:
Could someone give me some help with this modification if I post some pictures of my remote? I currently have the mk161 module built and the 8049 added to my harmony.
I have 2 questions however, 1 is on the same direction as above. I have a remote that uses 2 AAA Batteries for total of 3 volts. The power supply I am powering the mk161 with is 12V. My question is when I come out of the 2 channels of output on the mk161 to go to the remote, do I have to have a dc-dc step down converter in-line on each of the 2 output channels between the output of the mk161 and The 3V remote control.? I plan on continuing to use the 2 AAA batteries to power the projectors rf remotecontrol.
I?m not very sure of myself when it comes toelectrical so it’s possible that what I just said makes no sense at all. Because if the power to that circuit is coming from the 2 batteries, then will I even need step down converters??- Iguess I’m just afraid that when I solder the wires coming from the mk161 to the proper places on the rf remote circuit board that I will blow it up and I’m confused if the voltage differencebetween the 2 pieces will mess something up.
The second question is the buttons on the rfremote control on the circuit board look like they are made of a thin concave piece of tin that pops in on the center when pressed. There is a thinclear sticker over the area where this described component is. So the question is, how do Isolder to it? (Since it is under the transparent sticker like material and where do I solder my + and - wires to on the described components?)
I am going to try and attach some pictures for in case my descriptions are no good.
Thank you all so much in advance!!
