Post by thread:Anyone have experience with this programmer?

part 0 2502 bytes I haven't actually built my programmer yet, but this is the one that I think I'm going to build.  It is inexpensive and seems to have good compatibility. This is the URL: <A HREF="http://www.ebar.dtu.dk/~c888600/newpic.htm" TARGET="_blank">www.ebar.dtu.dk/~c888600/newpic.htm</A> Has anyone worked with this programmer before?  Has it worked good for you? Thanks in Advance. Rick. </UL> This is a design that uses the voltage available at a PC's serial port to generate Vcc (5v) and Vpp (around 13v).  The design has been around for years and has the advantage of simplicity and no external power requirements.  However, the success of this programmer depends largely on the ability of your serial port to provide enough current/voltage to the programmer.  Some PC's are ok, other's aren't.  Notably, laptops seem to have the most problems with this type of programmer. If you are on a budget then I recommend you get/build a parallel port type programmer.  This uses an external supply and tends to be far more relaible than the serial port types.  There are literally hundreds of designs for these types of programmers, you will usualy see them refered to as "Tait" type design after David Tait who designed one of the original programmers.  I personally have a P16PRO kit at home and I've never had a problem with it.
