Reviving a dead arduino

Well I managed to kill my arduino. It no longer accepted uploads with the classic out of sync error. After asking on the arduino forum I was told I would need a high voltage programmer to rectify, so I decided just to buy a new chip.

I was a bit scared about doing this but it was really easy and thought I would share my experience. 

Step 1 Gathering the parts

After having a look at the price of high voltage programmers, I decided it would be cheaper just to replace the chip on the arduino, and at least this way I knew I would have a working arduino.

I found the cheapest atmel 328p (the same as was coming out of my arduino, with the arduino bootloader preloaded on it) on ebay, buy it now from the UK so I would have it as quick as possible so I could continue with my arduino powered project (await future instructable ;) )
Total cost: £5.90 delivered next day

This didn't solve my problem after all... well assuming the guy on ebay actually installed the arduino software... I think ether my board or my drivers are messed up. tho i wont know for sure for a while.

Sorry to hear that, what does your board do when you power it up/ hit the reset?

[kyle brinkerhoff]

you know, if you go to the right place (actually show up physically at their store) alot of times if your only getting one chip they'll give it to you for free!

[xana]

where name the sight

[kyle brinkerhoff]

you have to show up in person....

[the_burrito_master]

Yes! my arduino has this exact same problem thank you so much!

[datahar]

Have you tried bitbanging the chip? Buying a new one is really the last resort

[the_burrito_master]

Bit banging the chip?

[datahar]

You can rewire your arduino up to write to its own chip to reprogram it The tutorial I followed was http://www.geocities.jp/arduino_diecimila/bootloader/index_en.html

I tried it but I don't have net framework 2.0 and cannot get it. So I think all i can do is buy a new one. thanks for trying.

Thats a shame, I know the latest (I believe) Arduino 0018 build has a burn bootloader via arduino, something I still need to do to see if I can salvage my chip would be interesting to see if it could be used for bit banging

[the_burrito_master]

yeah it does have that but it doesn't work, unless it only works if you modded the chip for bit banging before hand. I might give that a try.

[the_burrito_master]

Oh yes well i want a second avr anyway and it's easier to program it with a bread board.

i do that a lot but i just buy the chips form atmel and program them myself by bit-banging them or using a adafruit tinyusbisp both work well

[datahar]

Think I am going to do that next, with being unable to bit bang my chip back to working order, I lost a little faith and just wanted my arduino back so I can carry on my project.
