Paper Silk Screen

Tuesday, September 30th, 2008

No project this month since I’m to busy working, really, I can’t stand to look at another PCB, I made like 20, 25 boards in one month, my hands smells like ferric chloride.
That and I can’t find a MAX3232 in dip package around here, gona have to order one on-line and that takes time…

Anyway, I needed to make a prototype for a friend, and since I was not the one to use it and didn’t want to make a sketch with the positioning of the buttons and LEDs I decided to try something I have seen in some blogs for some time.

And as you can deduce from the title of the post and the big photo over there, I printed a silkscreen for board on paper and before soldering everything put the paper between the board and the components.

Surprisingly, it turned out great, I don’t know why, but I thought that the heat was definitely going to stain the paper.

But I still have a doubt, I used masking tape to hold everything down, but there got to be a better way.

Anybody who has used this method before knows a better way to glue the paper on the board?
Glue? Hot Glue? Glue Stick?

More videogames…

Last week my good friend Gabriel invited me to a game party to test his new TV, which has a VGA input that allowed us to display his note screen on the TV. I was working on 3 different projects at the time without a focus on one, but since one of the projects was a board for the USBJoy project that I found on the ObDev site, I rushed to make a prototype of the board to test it and have fun at the same time.

The prototype worked well under Windows XP and Linux, should work on Mac to, since it is a HID (human interface device).

The USBJoy connects Dendy (Russian NES), SEGA Mega Driver II and PlayStation I and II to the computer trough a USB port, but the board that i’m making only works with PlayStation I and II.

Anyway, the layout of the board is ready, I just need to make one board and test it before putting on the site.

So probably this week or the next the project should be up.
