Rpi radio transmitter.

Posted 01-30-2017 at 09:57 AM by peonuser

Check local laws before setting this up.

PiFM sorta
Wanted to be able to send music to speakers outside the house say for a barbecue or whatever. Could use Blue tooth among other things, but I wanted something more secure and easier to generally implement. PiFM seemed to be an answer . With a RPi you can send an old fashion radio signal to a radio and the radio will play what is sent it. All you need is an up to date Raspian install on a Raspberry Pi with internet access....

Have a barebones arduino working with the enc28j60 via battery power as a minimal web server..

Next project is to use arduinos as a/d converters for use the parallel port and the Rpi.

Made a usb ethernet gadget with the RPi zero.

Bad documentation?

Posted 12-15-2016 at 01:55 PM by peonuser

Sometimes you just want to tear your hair out when the documentation of a product is WRONG. Something I ran into recently when trying to attach an enc28j60 from Hanrun to my genuine Arduino. I have used the ethernet shield on the Arduino without a hitch. So I supposed there would be no problem again... So I thought. Followed the map for hooking the two devices together as follows:

VCC - 3.3V
GND - GND
SCK - Pin 13
SO - Pin 12
SI - Pin 11

Just talk.

Brother gave me a small pre-hdmi flat screen. That freed up other monitors.

Have been using kodi more and more. Still have to set up the time server access.

Gave my niece an old wok. Sure she will appreciate it.
