\"\"<\/a><\/p>\n

For the last year, I have been using an Arduino board and the associated IDE to build a few projects around the Atmega328.<\/p>\n

If you are willing to live with miner limitations; boot loader, hardware wrappers (timers, interrupts), …, it\u2019s a very handy solution.<\/p>\n

The only major annoyance is the scarceness of the Atmega328 or 168 chip!\u00a0 Try to get one with DIP package at a reasonable price… It\u2019s been out off stock for a while now at DigiKey<\/span> (well I guess not anymore: DigiKey<\/a>, Mouser<\/a>)<\/p>\n

I saw, on eBay, a seller that was asking 1,99USD + 8,50USD for shipping \u2013 for one Atmega328.\u00a0 I said to myself, hum, it might be a good opportunity for 10 pieces.\u00a0 So I asked the sealer.<\/p>\n

Surprise! (well, not really), I got this:<\/p>\n

Dear aboudro,<\/strong><\/p>\n

\u201cFor normal price of total price 10units(Atmega328) is $105 but for you that special price of total price 10units(Atmega328) is $85<\/p>\n

Best regards,<\/p>\n

Great, He gave me a special price on shipping, 65$ to send a 2 ounce package.\u00a0 I felt so lucky.<\/p>\n

Back to my story;<\/p>\n

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.<\/p>\n

Their IDE is a pleasure to work with and I like the idea of \u2018in circuit programming\u2019.<\/p>\n

My next AVR project will be a frequency counter – on the local oscillator- with I.F. adjustment \u2013 for a vacuum tube, shortwave radio I am working on.\u00a0 See this post: http:\/\/ve2cuy.wordpress.com\/vacuum-tube\/project-4-sw-tube-receiver\/<\/a>.\u00a0 It will be used to display the tuned station frequency.<\/p>\n

I will start by using a Hitachi<\/em> HD44780 compatible LCD display but I might switch to nixie tubes.<\/p>\n
