| Oct 1, 2010 at 0:49 | comment | added | Jack Schmidt | I did see some instructions on making a high voltage programmer (and the datasheet for the chip seems to have pretty detailed instructions on designing one), but I'm waiting until I brick one of my chips until I try it. My oscillators get here tomorrow, so I'll be burning fuses and tempting the brick fairy soon enough! | |

You do need an high-voltage programmer for that sort of thing. [1] mouser.com/search/… [2] ladyada.net/make/usbtinyisp | |
