Hold on to that pile of gold

For the last year, I have been using an Arduino board and the associated IDE to build a few projects around the Atmega328.
If you are willing to live with miner limitations; boot loader, hardware wrappers (timers, interrupts), …, it’s a very handy solution.
The only major annoyance is the scarceness of the Atmega328 or 168 chip! Try to get one with DIP package at a reasonable price… It’s been out off stock for a while now at DigiKey (well I guess not anymore: DigiKey, Mouser)
I saw, on eBay, a seller that was asking 1,99USD + 8,50USD for shipping – for one Atmega328. I said to myself, hum, it might be a good opportunity for 10 pieces. So I asked the sealer.
Surprise! (well, not really), I got this:
“For normal price of total price 10units(Atmega328) is $105 but for you that special price of total price 10units(Atmega328) is $85
Great, He gave me a special price on shipping, 65$ to send a 2 ounce package. I felt so lucky.
Back to my story;
Atmel makes a lot of fine and available chips so I got myself an Atmel AVR ISP In-System Programmer and some ATTINY2313-20PU-ND.
Their IDE is a pleasure to work with and I like the idea of ‘in circuit programming’.
My next AVR project will be a frequency counter – on the local oscillator- with I.F. adjustment – for a vacuum tube, shortwave radio I am working on. See this post: https://ve2cuy.wordpress.com/vacuum-tube/project-4-sw-tube-receiver/. It will be used to display the tuned station frequency.
I will start by using a Hitachi HD44780 compatible LCD display but I might switch to nixie tubes.
To be continued…
