Good point to add. I received two of the newer ones from one supplier and one of the older ones from another supplier, with all three orders received within a day or so of each other. Clearly, some suppliers still have old stock on their shelves. I added the resistors, of course. But it's work asking before buying, if possible, and watching out for it otherwise. Jon

AND ALSO! ... Do not install the software from the supplied CD; get the latest versions from the Microchip website. In any case, there is a slip of paper in the PICKit2 suggesting that you should do that.

HEY IDIOT YOU ONLY NEED 1 RESISTOR: http://home.earthlink.net/~davesullins/software/pic18f.html HAHAHAHAHAHAHAHAHAHAHA LOL WHOOOOOOHAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA LOL ahahha jippi!!! fun fun fun. Save a couple of dollars. LOL

If you want to build, take a look at the Wisp648: http://www.voti.nl/wisp648/index.html. The PCB is not available for free, but you can buy a kit or lay out the board yourself and buy a pre-programmed PIC. This programmer handles a lot of different PICs, but only 5V ones. It works with both Windows and Linux. >I've never laid hands on one >so am I not sure what to look for. You absolutely want a programmer that supports ICSP (In-Circuit Serial Programming). Moving the chip back and forth between the project and the programmer gets old very fast. >I am a hobbyist and would like to program the occasional IC just to >simplify my circuit building. It would be nice to program a wide >variety if chips but in reality I would probably just pick a few that >I was comfortable with and stick to them. I have the PicKit3, and I am very pleased. In addition to programming almost all PICs, it also has basic debugging capabilities. The debugger is more useful than you'd expect. >My programming skills >aren't all that great. I'm comfortable with editing VB script or >using graphical programs. If I have to I could probably learn basic >or c. I have not been able to find any decent, free Basic or C compilers for the PICs. If you're going to learn a new language anyway, take a look at JALv2: http://www.casadeyork.com/jalv2/. There's also a mail list at Yahoo groups where you can get help. >The less code I have to write the better. I would like to keep >the price tag under $60. I've read that it's best to get one that can >be debugged in place so that would probably be good too. I think you'd be well served by a PicKit. The 3 has been getting some bad press, but mine has been fine. -- RoRo

For a hobbyist I'd have thought a kit might be ideal. The suggestion below is a bit too minimalist and unsafe for my liking. YMMV > > HEY IDIOT YOU ONLY NEED 1 RESISTOR: > http://home.earthlink.net/~davesullins/software/pic18f.html Provided that you don't mind the risk of damage to your parallel port. The design is totally unbuffered, voltage dependent and may not work, and some of the suggestions there are likely to wreck a PIO if used by the unwary. Older chips also want a higher programming voltage applied. But there are cheap DIY PIC programmer kits for hobbyists about. It is quite cute to make designs fully in circuit programmable.
