does anyone know of a cheap and good homemade programmer schematic?

Thanks

The PROPIC from Octavio Nogueira is a very nice multi-purpose PIC
programmer with software.

David Tail has an excellent page with (among other things) lots of links to
programmers (http://www.man.ac.uk/~mbhstdj/piclinks.htm).
My own design (http://www.xs4all.nl/~wf/wouter/pic/wisp) is good, but much cheaper
designs exist.
regards,
Wouter.

Hello,

What types of caps are reccomended for use in the circuit & where?

We use the 'Ludipipo' serial programmer - it's very simple and may be
interest.
Let me know if you need a PCB layout.

English summary by Michael Covington,
http://www.ai.uga.edu/faculty/covington

*****************************************
LUDIPIPO 1.0 programmer for PIC16C84
------ LUDI's PIcPrOmmer ------
for the serial port
- direct connection, 4.5cm x 4.0 cm
Ludwig Catta :-) 12.12.1995
*****************************************

LUDIPIPO is a programmer for the PIC16C84 (only) that attaches to,
and is powered by, the serial port of a PC. It assumes that the
high level voltage coming out of the serial port will be at least
12 volts. With different software, it could also program the
PIC16F84 and perhaps the 8-pin PIC12 series.

The idea came originally from Erik Hermann.
Here is the schematic:


TxD ---*-----------------------------
(3) I I
--- ---
I I I I
I I 2.2k I I 10k
--- ---
I I\I I
*-------I-I-----*--------- I
I I/I I I I
----\ I + I I
/\ \ --- 14 I I 4
/ \ 5.6V --- --------------
---- 10u I I Vdd Vpp I
I I I I
I I 5 I I
GND ---*---------------*----I Vss I
(5) 22k I I
----- 12 I I
RTS ---------I I----------IRB6 (clock) I
(7) ----- I I
----- 13 I I
DTR ---------I I----*-----IRB7 (data) I
(4) ----- I I I
2k2 I I PIC 16C84 I
CTS ------------------I I------------I
(8)

The pins of the 9-pin serial port connector are in parentheses.
Note: No power supply is required; nor a double-sided circuit board;
and we're not selling anything.

The resistor values are not critical. Instead of 2.2k, 2.2k, 10k, 22k,
I have used 1.4k, 1.4k, 10k, 16k. The original plan had a 100-uF
capacitor which I replaced with a 10-uF tantalum. There's not much to
install, not much to solder. Be sure to get the diode and the capacitor
installed the right way around.

No special requirements for the caps. See the schematic and the PCB at
