Adafruit Pi Box - With LCD & RS232 DB9 by waterbury Jul 3, 2012

Description

Modified Adafruit's Raspberry Pi Box to accomidate Longtech 16x2 LCD Module. Also added RS232 port on side. With a Max3232 chip you could turn the TTL UART pins into RS232 level.

Yeah, this looks like a really useful thing, what exactly is it you are complaining about?

Instructions

LCD could be purchased here:
nkcelectronics.webstorepowered.com/16x2-Module-white-Backlight-Arduino/dp/B007LO3Y9W

Code to drive the LCD via Python is provided by my friend, and fellow FamiLAB member, Lance "lrvick": github.com/lrvick/raspi-hd44780

I used four 2-56 threaded 1/2" screws to hold the LCD in with.
You Could purchase them as a part of a pack from Radioshack:
radioshack.com/product/index.jsp?productId=2103300

Three hex nuts for each screw was used makeshift standoffs. The same nuts screwed the LCD into place.
The nuts were also bought from Radioshack:
radioshack.com/product/index.jsp?productId=2103302



This is all sized for 3mm acrylic. With three nuts as standoff, LCD is flush.

Blue Vectors are inside cuts
Green Vectors are for Outside cuts
Red should be treated as raster.
Black should be cut as Raster, do not cut them as vectors as you'll have too large holes.

If you desire recessed screws:

My hackerspace has a 40 watt Full Spectrum Hobbiest Laser Cutter. I cut at 15% speed, 100% power, 1000DPI in Retina Engrave with laser set to 10mA. This etched deep into the acrylic around screw holes for LCD to allow recessed screws. This is optional, and should only be used on the file with the black circles though. I put the LCD panel mount in a seperate SVG, so you won't have a conflict with the raster settings of the red text.

Looks like you need to go back to school and take website building 101.... Before you try to sell anything.
where are her internets?
