also for some persons in countries with small currency, like ours, it might be over 300% of your monthly wages. eg: picstart+ in India is around 18,000 indian currency. and average salary for a professional at entry level varies from 4,000 to 6,000 in an average size company. So homemade is the only alternative.

And if that pencil had a ZIF socket on it like most good PIC programmers, you can tack on another $25 just for it.

There are people who have access to old electroncis, but not new stuff, and some people would rather make a pencil than buy one, just for the fact they can. If I am correct, programmers are only trying to get certain voltages to pins at certain times. the sequence is important, but how they get there is not. ie: one can use transistors or a PIC, depending what one has on the bench. A single chip unit (18 pin) is really the same as having a socket for an 8 pin, an 18 pin, a 28 pin and also a 40 pin on the board. The idea of the single socket type is just small board size. There are quite a few schematics on the web that detail different levels of programmers from a one wire (one resistor) to things like the WARP that does both Atmel and PIC chips. here is a very simple unit. http://webspace.webring.com/people/jl/leon_heller//pic.html and go thru this site and see the different programmers that the software supports. And if you want something even better, check out Wouters Wisp628. Dave

I got your idea, but you know , some people will try to 'make' something what costs almost 1/4 from the month wage! So I 'm still with the idea of making the programmer home. Too bad is I don't have the schematics from well known good programmers. I will try to use JDM, but I must be somehow sure the debug problems are not from bad PIC programming. The other part is I really really don't like black boxes. And the surprise in bigger when you open a black box which you paid already for and you see there are just a few 25 cents components each. > Second thing goes to the cost of making something. > > How much would you charge to make me a pencil ? you would need to > get the wood, the lead, some metal and rubber, along with some paint. > > Don't worry about sharpening it, I can do that part. > > And remember, I can buy one already made for about 25 cents. > Dave

One is that you can buy a programmer from MicroChip for under $50.00. You can buy the Wisp628 for under $30.00 or a JDR kit for around $20.00 all support ICSP, and Wisp is strictly ICSP. Second thing goes to the cost of making something. How much would you charge to make me a pencil ? you would need to get the wood, the lead, some metal and rubber, along with some paint. Don't worry about sharpening it, I can do that part. And remember, I can buy one already made for about 25 cents. Dave

Hello, I want to bring in attention an old subject but in another light. I use JDM programmer as a PIC serial programmer. I read that it supports ICSP but I'm not sure. My question is what is a good programmer on the web with all those : - can be build home (no problem if many components involved) - has a true power supply, to avoid hazardous signaling - respect microchip programming standards for PIC - can deal with all (at least most popular) PICs - can be use with a software programmer (windows or freebsd OSes) - can support ICSP ( is this related to the programmer or not? ) As I said , I use JDM serial programmer, but from what I saw on the schematic description, there are some spikes in the signal, the power supply and signals are not so true generated, and I experienced some failures if I used serial cables longer than 1 m. I can't spend $100 for a microchip pic programmer, you know with $100 you can buy a powerful GPU graphic card, which is far more powerfull than a PIC programmer. thanks
