 Bigger Bigger  Smaller Smaller  Reset Reset

Hi - After browsing through this forum, and others, I came to the conclusion that LOTS of people have issues uploading the bootloader / programs to there blank atmega/attiny chips. So I have made the following 2 boards :

Arduino as ISP Mini board, Fits onto the ICSP header (With a lead going to pin 10 for reset).
and
Arduino as ISP Shield, Complete with the Heartbeat, Error and Working LEDs.

Just upload the ArduinoISP sketch, fit the Mini or Shield, then disable the reset on you Arduino (The shield has a jumper to do this)
pop you chip onto the relevant socket, Choose the correct chip from the tools menu, Select Arduino as ISP in the tools menu.
Then upload the bootloader or (if using the up to date IDE) upload the program with programmer.

See the attached images.

They are for sale if any-one wants one (or both).

Nice concept, but consider replacing the sockets used on the ISP board with zif sockets.  The normal sockets your using are not designed for repeated insertions/removals and will quickly wear out.

I agree, But I tend to hold the chip in place, rather than insert the chip fully, so wear is minimal. Also ZIF sockets are quite expensive compared to the standard DIP sockets.

Here's something I cooked up for my own use:





It's just the DIP socket broken out (Up?) to the shield and the 2nd socket is configured to burn the bootloader. Without the 2nd chip in place it operates normally and once projects are nailed down the chip can be removed for standalone apps. and another bootloaded chip can be installed for the next go round.

Pull both chips and it's a programmer:



(The sockets have to be empty for loading sketches. Unlike the pic...)

I'm planning on breaking out the pins needed for programming for use with a single cable instead of the jumpers.

But, yea, the ZIF sockets would drive up the cost.

I'm putting up 2 of these to swap. Leave an offer here or PM me, I'm not after anything specific, does not even have to be arduino related, But preferred.

I've Built & Tested the shields with :

atmega 328
atmega 168
atmega 8
(All set to internal clock & Oscillator)
tiny 13,45,85 all on internal Osc.

I'll post to world wide (With a few restrictions).
