Ever thought of taking SPI out of the Atmega 168 directly to a MAC enabled ethernet chip?http://www.microchip.com/wwwproducts/en/en022889

Making a typewriter with an old keyboard and a dot matrix printer
Laser Transceiver (laser data link)
hello! this is really a great project!!I was wondering if it is possible to control, for example, the space between the letters, or something like that - by messing with the code, or actually put that function in one key of the keyboard.Also, this code can be used for a bigger dot matrix printer? A4, A3 paper size?Thank you!
Hey Perfo,I have limited data internet over the phone and it is expensive compared to line internet. Obviously. Can't use RF based solutions as there is a huge possibility of interference due to unavailability of fully clear line of sight. But I do have a line of sight.Can you please share a little more details about your hack. Can you give out details of the media converter, LEDs, receiver and other hardware that you used for the project and what were the problems that you faced? I would really appreciate if you give out these details.Thanks in advance
it was a compilation problem, only updating IDE and fix it.
i have same problem, did you fix it?
I reply myself... update your arduino IDE... :P
I doubt this is fast enough for quality data transfer and that laser and photodiode is probably not fast enough to operate in the MHz stably. I would recommend an avalanche photodiode and an IR laser diode (850nm or 1310 nm).
You just can Connect the Laser to Pin 0 (TX) to the laser and connect the photodiode to 1 (RX). Do so with 2 Arduinos. Now set a Low Baud (1200) and Print Something in the Serial Monitor on the First Arduino and it will Echo at the Second!
The resistor behind the mosfet is 10k, but i cant make out what the one next to the LED is... probably like 100 ohm?Theres only one capacitor, 100nF (yellow)The orange one is a 20MHz resonator :)
Did you ever try the media converter hack?
Hello :) Did you ever finish the project?In that case, can you tell me how you solved this gradual drop?
