I posted recently about detecting power loss in an AVR and quickly writing values to EEPROM before power is lost completely and have since received the PCB’s I ordered from oshpark.
This is the first time I have ever ordered professionally made PCBs. I’ve made many using photo resist or toner transfer, but at US$5.00 per square inch for three boards (including worldwide postage) I decided to give it a go. It took a total of three weeks from placing the order to arriving in New Zealand.
![And this is what they arrived looking like.](https://www.john.geek.nz/wp-content/uploads/2014/08/asreceived-257x300.jpg)
I don’t think I’ll ever make a board by hand again (provided I can wait the manufacture and delivery time). This order came to US$9.10 for three boards…
