Raspberry Pi Power and RF Hat


So i know that I have been living under a log, but on the Pi you can modulate one of the GPIO pins and create a rather rudimentary transmitters. Now this outputs the sum of all the sine waves HEHE and the GPIO pins are not very clean also passing on any power supply ripple and the like. So it need to be filtered quite severely. So with that in mind, I have put a double tuned band pass filter inline to clean things up somewhat. I will take a look with my spec-an when i get the boards back and see if its actually clean enough. Some say it is, but I like to see for myself and not jump to conclusions. There is enough wrong on the internet as it is from monkey see monkey do copying others mistakes.

The other thing i have added is a DC barrel jack to power the Pi. I have a couple of 5A 5V PSU’s so its a bit of a no brainer to power it that way and it saves on breaking the micro usb connector off eventually. The other connector is a USB A socket to supply power to the HDMI LED Display that I use. I have a bigger one coming, a 7 incher which will make developing on the Pi a little nicer than using the 5 incher i have on there currently.

I got a few other things in the plans to play and experiment with in the pipeline. So there are a bunch of cool posts and videos in the pipline. Oh and I have the board files for the uSDX as well which will get sent of with my next order. Should be a cool project.


Fun With Raspberry Pi

So i was going to make a really nice post today explaining the things I was doing with the raspberry pi. Instead, I have spent the last hour fighting with windows to give me access to the SD card on my phone so I could add this picture to the post. Why is it, that windows always breaks something every time they run and update and we have no option but to update or the scammers will hijack our shit.

If it was not for HRD, Diptrace, Vegas Movie Maker, and Photoshop i would dump this pile of windows shit and go linux. Well then I would have the problem that my HP keyboard does not play well with it because it defaults to multi media keys for the function keys. Nothing is ever simple. So my spend a few hours tonight learning how to so some cool things with the Pi ended up being a waste of time dicking about trying to get a picture off my phone.

HAHAHA. Failure is always an option.
