Development board

Google "Use Arduino as AVR programmer"

How it's written by Genesis: "There must be some misunderstandig, there must be some kind of mistake ..." Or maby I just need another hint, but I just asked for a schematic of the pref board shown in last video (that funny automatic shades) on 03:30. The board, where point with your finger on. In the video you told us the viewers that you will use the AVR-Studio together with the AVR ISP mk2 programmer. Why should I need an arduino as programmer if I already have an AVR ISP for programming?

you mean the little circuitboard that has 2 dip sockets for avr chips that ben uses to prototype his arduino/avr projects on id like to know how to make that too ben can you do a mini tutorial on one of the shows detailing how we go about making our own microcontroller dev board if you want to go for a fully fledged show idea you could perhaps make the board universally compatible with both pic and avr programmers by having them share common components and also include other little micreocontrolelr related things such as building a programmer that uses a usb to serial cable to program the pic and avr mainly avr if you could do a show on theese topics that would be awesome

The board looks to be a couple of sockets which are directly wired to headers on the board so you can hook things into them, a linear power supply to drop the wall wart voltage down to a micro controller safe level, probably 5V, and then a connector for the programmer which is then wired to both sockets to the 5V/MISO/MOSI/RESET/SCK/GND of the micros

That is a really long sentence!

Will I ever get an aswer?

Do you mean the PCB I had on the show with sockets for ATMEGA and Tiny?

The chip you're programming is on the right.

Basically you need the SPI bus, Reset, Power, Ground and Crystal.

You'll need still an external AVRISP Mark II programmer to connect to the header, or use Arduino as ISP (see Ardunio site for details)

Yes, it exactly that prefboard which you used to program the ATtiny. But there is no socket on the Arduino Uno for an ATtiny ?!?

Here's how it works:

A regular Arduino must first be programmed with a Bootloader. This is done via the SPI bus and the AVR Programmer.

Then, it can be programmed externally via its RX/TX port (serially)

ATTINY can be programmed via SPI and AVR programmer. You could breadboard it, and use jumpers to connect it to an empty socket Arduino. Google "Program ATTINY with Arduino"

The catch is there's no RX/TX, so you'd have to use AVR Studio, WinAVR, or compile with Arduino and manually burn the hex file.

I found this schematic and modified it a bit. Do you guys think this would work? Hope to get a respond!
