First Product for sale! Sharp Memory LCD Breakout

Sharp Memory Lcd Breakout and Library

Hello?  Anyone home?  Echoooooo?
It’s been pretty quiet around here lately in Rengineer land.   I’ve been letting this site sit for too long.  However, this is going to be a big week.- Makerfaire is coming to New York!  The Open hardware summit is here as well.
Today is a little different though – today I’m bringing out a a project I’ve been working on for the last few months – my first open hardware product, a Sharp Memory LCD breakout, and an Arduino Library to run it.

A wise man once said “Bringing a product to market is like having kids and kicking them out of the house all at once”
I’ve definitely found this to be true!
I’ll try to document the process over the next few weeks – but right now, I’m proud to show off the fruits of my labors.
Sharp makes a number of interesting LCD modules.  This particular one is part of the “Memory LCD” series.  What makes it special is that it doesn’t use polarizers.  That causes it to have a really interesting “reflective on cloudy” effect – unlike any LCD I’ve ever seen before.
So – Check out the LCD module.  I have two videos of it up on youtube:


If you like it, the breakout (with LCD) is available for purchase on tindie:

As always – this is an open source release – everything is on my github here:

    Hey! I saw your board at MakerFaire. It looks great, and I’m loving the µA/pA power consumption aspect.
    I’m trying to think of a project to use it in; once I do, I’ll grab a couple from you.

    Enjoy the rest of MakerFaire!

    thanks for sharing the code for talking to the sharp memory lcd. i would like to extend the library with more fonts and i was wondering what tool you used to generate the setfont.h file (currently only orbritron)? if you could point me in the right direction, i will add some other fonts.


    • TheRengineer says:

      Hi Rene,
      I really have to write up a tutorial on how I created the fonts – It’s not too hard though. I used To convert truetype fonts on my PC. Once i had the file output from the dot factory, I used (not shareware, but there is a 30 day free trial). 010 has a nice feature to “cut/paste as C code” and it pretty much does all the hard work for you. I believe I have a max fonts variable set to 5, but the real limit is the amount of flash you have available. Be careful – – fonts eat it up quick!
      I realize this is really a quick overview – let me know if you have any questions.

    Any idea when this will be back in stock? I really need this to start a project of a digital watch for kickstarter.

    • TheRengineer says:

      Ben – I should have the LCD’s back in stock early next week. I’m adding the option of 3.3v or 5v input (via jumpers). I also have the “second generation” 128×128 transflective Sharp Memory LCD’s as an option (though I haven’t updated the library to support it yet).
      If you have any questions, contact me at or via tindie.

    The public handicapper usually gives odds and predictions for just a race track or
    perhaps a local newspaper and even one of many data or program

    have a living from it. Similarly, Johnson could possibly be gone soon, and Nannes’ deliveries could join the planets, in orbit.
