Help with in-circuit programming ATTINY45 surface mount, no header pins

[yary hluchan]

My partner has painstakingly soldered together 10 of these- http://cdn.instructables.com/FF5/1HU0/2RCEWP7OER2/FF51HU02RCEWP7OER2.MEDIUM.jpg

But despite much careful work, we cannot get the software loaded into it. It seems to be simply that we can't get a good connection from the Arduino that we're using as an ISP to the pins/pads of the microcontroller, despite careful work. These are for an art piece that is meant to be installed on Monday(!) near Parrsboro. Is anyone around that has flashed a hex file onto an AVR ATTINY45 microcontroller, with time to show us/help us get the code loaded onto them? Email me here, not.com at gmail.com

ps. I posted this a little earlier to the Halifax makers, which is closer to where we happen to be at the moment, but a) we will take help anywhere we can get it and b) most of our chips are near Parrsboro, which makes Moncton more convenient. Apologies to anyone subscribed to both these lists. And thanks for being here!

I only have tiny85s, but they're the same deal as 45s. Slapped it together and got it running. Minor edit to the makefile, and I had to patch the arduino ISP program to use it for uploading. Not clear on what the actual error messages/ uploading problem is. I'll email you my phone number and if you give me a call we can see what's up.

Couple questions:

Is the programmer timing out or are there protocol errors?

Are you using the arduino ide to upload the firmware?

Did you change the fuse settings on the tiny 45? (defaults from factory are fine)

Cheers,
Nick
