Re: Pi in a NES Cart

I was just thinking, it would be awesome to add a pressure sensor inside the bottom which controlled the power. Then to get it to work you have to blow into the bottom and it boots. XD

Re: NES Zero - Build Log

Thanks jonbro. The audio is not the best (by far) but just having the audio there while playing adds a lot to the gameplay. At first I just connected a piezo element between pwm and ground, but as I could not keep the housing on the piezo due to size constraints, the volume was quite low. Low enough...

Re: NES Zero - Build Log

Got the power all wired up last night... As soon as I get a chance, I'll add a parts list here too.

Re: DIY Safe Shutdown w/ PowerBoost

I believe I saw this diagram online somewhere as well. I think it was a video on soft latch switches? These circuits are ones I made from scratch in the falstad circuit simulator, not nabbed from somewhere else, but I'm sure there are similar ones floating around. It's kind of like the guitar, ther...

Re: Multi Circuit Switch

Can you please provide more details about exactly what you hope to accomplish? These are fans correct? Are you using pwm for the LEDs? Single color or rgb? Any number and combination of fan LEDs on at the same time or one at a time? Is there a datasheet for the exact fan you are using? It's hard to ...

Re: DIY Safe Shutdown w/ PowerBoost

The circuit posted above works well, but upon thinking about this some and doing more real world testing, you can get away with a much simpler circuit. The circuit shown below has nearly half the components and works the same way.

Here is the link to the simulation.

Re: NES Zero - Build Log

Thanks guys.

Here is a circuit layout which I had entirely too much fun making in MS Paint.

Re: NES Zero - Build Log

I stayed up late and got the wiring done last night and it booted straight away. That's a first lol
I still need to add the battery and the powerboost... it's just hard wired for now, but I'm really happy with it!

Got the start & select buttons added and the connections all figured out. I think I'm going to wire the screen and buttons first and test before moving on to the power side of things. It all fits nicely in the case though. Hoping to wrap this up by this next weekend.
