Re: Connecting NES to Teddy Ruxpin

If you take a 50 ohm resistor and connect it to your controller port, there will be 100mA there, and that is OK for the nintendo. But that is not the same as connecting a 100mA motor to the controller port. There is a very important difference that I have been trying to explain to you. Oh ... See, ...

Re: Connecting NES to Teddy Ruxpin

I found some technical documentation today that mentioned amps for the 2941 Micro Servo: Running Current (at no load): 100mA (4.8v) / 120mA (6v) So, I think we considered the 100mA to be too much of a draw. Or ... I do have an NES where the audio is broken at the RF cable input. I am not partial to ...

Re: Connecting NES to Teddy Ruxpin

One big problem here is that the NES's CPU, PPU, cartridge, all the other digital stuff runs from its very modest internal 5V supply ... This is also what I was thinking, but my dad said the voltage didn't matter because ruining motors was going to come down to amps. I think I saw on the bottom of ...

Re: Connecting NES to Teddy Ruxpin

Could a big capacitor charge from the controller port and hold enough juice to power the servo for those (hopefully brief) times that a servo is running? Or will the mouth servo run pretty much constantly? Well, the mouth stays open when long vowels are passed through and is static long enough to s...

Re: Connecting NES to Teddy Ruxpin

Well, the only thing I found about using the NES controller as a power supply was this: https://m.youtube.com/watch?v=P0AOMkiIlYc NES powers a small screen and GameBoy simultaneously, so a mini servo (5 volts) or 3v to 6v DC -- is it that much more? Again, there is no mention of amps. https://www.ad...

Re: Connecting NES to Teddy Ruxpin

I wanted to post an update on this. I have a few Teddy Ruxpins at this point. I think I am going to use the third generation one because it only has two motors instead of three. I'm trying to pick one with a cassette drive that's truly broken so that I don't ruin a good Ruxpin. It's been easy to fix...

Re: Connecting NES to Teddy Ruxpin

I plugged it into my NTSC NES and it worked. Well, I could hear the background music for SMB3. Are you saying it won't work with the DPCM channel? I could go test it really quickly. Version is HC66-7. I think different versions might exist for NES and Famicom. Or someone might have done something to...

Re: Connecting NES to Teddy Ruxpin

https://imgur.com/a/HEqafPW I have this controller with an audio cable that allows you to plug in headphones to the controller. I was thinking ... I could just plug in a speaker to the headphone jack and stick it in the doll. Then, it would be easy to control audio from the NES. I think I could jus...

Re: Connecting NES to Teddy Ruxpin

I went back and looked and there was actually a 9v battery in the video, so I'm not sure what I was thinking (if that battery was even used). I already bought two bears online with books and tapes for cheap. They are partially working, just the mouths are broken, I think. I'm going to tear them down...

Re: Connecting NES to Teddy Ruxpin

The first test is going to be -- can I get power to flow from the NES to the motors and move the eyes? Not without exceeding what you're allowed to draw from the NES's controller port. Right now, I'm trying to find a Teddy Ruxpin that has a cassette player that is truly broken. I don't want to rip ...

Re: Connecting NES to Teddy Ruxpin

I see what I thought was a simpler way to do this, I replied on twitter, but it could use some elaboration. I had a Teddy Ruxpin when I was little, so it's kinda fun to think about. The MP3/WAV player chip on GTMP3 is controlled asynchronously, it's just 9600 baud and can be controlled easily throu...

Re: Connecting NES to Teddy Ruxpin

Might the current owner of the Teddy Ruxpin product identity object? I've read that one company to hold the rights successfully sued third-party publishers of compatible tapes . Oh, no. We're not going to be doing anything with tapes. I'm not selling anything related to Teddy Ruxpin nor producing a...

Re: Connecting NES to Teddy Ruxpin

I was thinking something like this Arduino Nano: https://www.aliexpress.com/item/32341832857.html Or like this Arduino Uno: https://www.aliexpress.com/item/32665372585.html Should work well and be within the $10 range. These should be available on eBay as well for a similar price. Using an Arduino/...

Re: Connecting NES to Teddy Ruxpin

I am going to completely discard the cassette and Teddy's circuit board. But that's my point. You don't have to. There's a lot of circuitry on the board that you could reuse, and it lets you keep more of the "authentically 1985" vibe going on. I would rather not use an Arduino because I don't think...

Re: Connecting NES to Teddy Ruxpin

One silly thought is that maybe if you can reverse-engineer the PPM encoded data on the audiocassette, you might be able to use the NES to recreate this control signal, and just reuse Ruxpin's entire circuitry. You could then plug the NES's audio output to the other channel inside. I am going to co...
