Minima - M1KTA bodges

As away from home at moment looking at the minima and the work from a few others... throwing my code bodges into github too https://github.com/m1kta/minima

I am going to be looking at the I2C libraries for the 4x20 LCD and adding a VSWR, Power Meter and Supply Voltage to the LCD real estate.

I like the option of using dual Si570 for the VFO/BFO and using an Arduino Uno and not the original base Atmega328 chip. I might investigate the use of the Arduino Mega 2560 (as I have one) as it has extra I/O and I2C dedicated already.

Also I have some alternate IF frequencies (as have the crystals) so might play a bit, as well as ADE-1 and SBL-1 mixers.

Python Panadapter for KX3 and UHFSDR

This has been done before with a RaspberryPi... but I found it lacked a bit on raw grunt and the tiny TFT was, well tiny... the Banana Pi with a dual core 1GHz CPU and 1GB RAM etc is an interesting option as almost all hardware is an upgrade from the earlier RaspberryPi, who (whom?) have said they will not update the RaspberryPi hardware until 2017) So I will be taking a look at using it and I will also employ a more friendly 7" LCD (ebay) with HDMI and a touch screen.

I don't want to grab an image that belongs to anyone else however these are what I will use

7" screen + BananaPi + KX3

 


+ bit of Python and a BananaPi flavour of Rasberian OS and you get this...

M1KTA 'library'

Asked recently how can I almost instantly recall or obtain details of circuits and designs....easy I have my own radio library. Quite a few volumes have been borrowed recently... No I do not post to anyone but I have found the odd thing for people (If I have time).




Bit of a shacky video (upside down as it happens!)
