anyways if u got the lcd working then the parallel-to-serial will be cake. i forget if those chips have built in pull-up resistors for the inputs or not. if not, you'll need to add those yourself. here is a helpful schematic

my crippling autism precludes me from relying exclusively on internal pullups

my goon project is to electrify this wooden baseball pinball game i got for xmas a few years ago, it has 12 holes for switches so that's why i need a 4x4 input matrix

if the internal pull-ups are good enough for I2C then they're good enough for me.

been messing around with high bit adcs for some work and personal projects. been using arduinos for some basic stuff (with an ads1115) but have for awhile been wanting something that I could program and use for more controls (analog out is really nice). wanted to work on using SPI to talk to a 24 bit adc (i know this is easily done on arduino but i wanted a more complete package) picked up one of these a few days ago and it is awesome http://www.cypress.com/psoc5lp/?source=CY-ENG-HEADER - you can find them for $75-100 depending im not a programmer by any means but its still been pretty easy to use. did a tutorial to make an led blink and had it communicating over usb with custom drivers to labview a few hours later. it uses a schematic ui that lets you throw down/connect op amps, adcs, pgas, muxs, DIOs, etc then switch over to the programming side to set up how it actually works while assigning all the stuff to custom pins also has a nice 20 bit delta sigma adc, can do a poo poo load of DIO and analog out as well with a bunch of premade package stuff for spi, i2c, usb, etc def recommend for people looking for more control/stuff to play with

that is incredibly stupid. you can buy a $49 brother laser printer and some $0.50 transparency sheets and a $5 clothes iron and do the same loving thing already e: also the laser will do hundreds of sheets at the very least and you aren't printing SILVER on possibly bad designs

tbh i didn't read it at all, just looked at the pretty pictures. lol @ this: SUPPORTER CARD: Thank you for your support! You will get one sheet (12pcs) of usb-powered supporter cards. You can plug a card into USB and turn a LED on. "you can plug it into usb and turn a LED on" basically sums up the maker movement

welp i was planning to make a MFOS Noise Toaster and i've been placing all kinds of orders on aliexpress.com to get the bits that i need but i find myself becoming dissatisfied with it, even though i've not built it yet. however due to the way aliexpress works, i'm going to end up with 10-20 of everything that i need. so i'm just going to make something else. something... bigger. i'm trying to scratch my modular synth itch without actually going down that particular rabbit hole, but i'm probably just accelerating my inevitable demise.
