Notesthese days you won't find anything that outputs s-video via two RCA cables. I've seen people make adapters from the standard 4 pin s-video plug to 2 RCA connectors, but I think I have a better solution.Unfurl
NotesWhat happens is that the contacts on the harness loosen over the years. The connectors also oxidize and start making bad connection with the board. As the resistance to the current goes up, so does the heat which burns up the connector.Unfurl
Notes Celebrate the 25th anniversary of that classic gaming device by building your own with 3d printing and DIY electronics from adafruit. In this project we'll use a raspberry pi and TFT touch screen to make an epic DIY gamegirl. FeedUnfurl
NotesArtisan is a software that helps coffee roasters record, analyze, and control roast profiles. When used in conjunction with a thermocouple data logger or a proportionalāintegralāderivative controller (PID controller), this software can automate the creation of roasting metrics to help make decisions that influence the final coffee flavor.

Notes If you've been following along here or on Twitter or Google+ you've no doubt seen the experimenting I've been doing with interfacing a Raspberry Pi in various ways with several retro computers like the Atari 800 and Commodore 64. My first project was using the Raspberry Pi to act as a converter for a USB gamepad to turn it into an Atari 2600 style joystick.Unfurl
NotesSince the Raspberry Pi was just sitting there, and the Amiga lacked (*) a network adapter - why not just connect the dots and get something up and running? I did, and it worked. Here's a quick writeup on what I did - if anyone's interested I can write a more detailed post with all the information I have.Unfurl

NotesThis Instructable shows you how to build a four-gang outlet box in which each outlet is controlled via an Arduino (or any other TTL level signals).
It differs from the other relay boxes in that it uses no circuit boards and has very few parts (one chip and 4 relays).Unfurl
NotesPirateBox can be configured to run on many devices, including wireless routers, single-board computers, laptops, and mobile phones. Key hardware platforms include the TP-Link MR3020 and the Raspberry Pi both of which start at US$35.Unfurl

NotesIf you simply remember how to do something, then all you can do is use it the same way over and over, but if you understand how it works, you can reason about it. Once you can reason about something in your mind you can contemplate why it is the way it is, you can apply your entire creative mind to making the most of it, and you can implement and question improvement ā you own it intellectually.Unfurl
NotesOnce upon a time, a boy met a girl. Then a short amount of time later, the boy decided to design and build a ring for the girl, because doing things in the most complicated way possible is just what he does to show the love. This is that story.Unfurl
NotesThe SPI (Serial Peripheral Interface) is a peripheral used to communicate between the AVR and other devices, like others AVRs, external EEPROMs, DACs, ADCs, etc. With this interface, you have one Master device which initiates and controls the communication, and one or more slaves who receive and transmit to the Master.Unfurl
NotesThis is a C library for Raspberry Pi (RPi). It provides access to GPIO and other IO functions on the Broadcom BCM 2835 chip, allowing access to the GPIO pins on the 26 pin IDE plug on the RPi board so you can control and interface with various external devices.Unfurl

NotesI finally dug out that LCD from the mess in my room and got it to work :) . Turns out , its really simple. You dont even need a microcontroller to do it.Unfurl
Notes Whenever you come across a LCD that looks like it has 16 connectors it is most likely using a HD44780 controller. These devices provide the same pinouts making them relatively easy to work with. The LCD uses a parallel interface meaning that we will need many pins from our raspberry pi to control it. In this tutorial we will use 4 data pins (4-bit mode) and two control pins.FeedUnfurl
NotesA couple months ago I saw an article or video of the worldās largest game controller and thought to myself āI bet I could make the smallestā and so I did.FeedEmbedUnfurl
NotesThis post is based on the work made previously by tomek in wiring LCD displays using 4 bits. The basic idea is to group the 7 pins that are needed to drive the LCD in only 3 using a shift register. This is a cheap alternative to serial LCDs. Unfurl
NotesHD44780 based character LCDs require at least 6 I/O lines from microcontroller to display data. Therefore, they are not suitable for low-pin microcontrollers like PIC12F series microchips. In this project, I am going to show how to drive an HD44780 based LCD display with only 3 pins of a microcontroller. I am going to demonstrate it with PIC12F683 microchip. The character data and command from the microcontroller is transferred serially to a shift register (74HC595), and the parallel output from the shift register is fed to LCD pins.FeedUnfurl
Notes Adding a LCD to any project immediately kicks it up a notch. This tutorial explains how to connect a inexpensive HDD44780 compatible LCD to the raspberry pi using 6 GPIOs. While there are other ways to connect using I2C or the UART this is the most direct method that get right down to the bare metal. FeedUnfurl
NotesWhen mine arrived, I didnāt really know what to use it for, but then it hit me: I can build an emulator box for all the NES and SNES games that I loved to play as a child.FeedUnfurl
NotesThe three models (all of which we use here at Digital Diner) are the Arduino, Raspberry Pi and BeagleBone. We chose these three because they are all readily available, affordable, about the same size (just larger than 2ā³ x 3ā³) and can all be used for creating wonderful digital gadgets. Before we get to the comparison, here is a brief introduction to each one.FeedEmbedUnfurl

NotesI've found that most of the technical books published before about 1964 never had their copyrights renewed, so now are in the public domain. So I am endeavoring to digitize and post some selected books relating to the "vacuum tube age" of electronics here.Unfurl
NotesOkay, so now I've got your attention - it's true - the cabinet construction was completed in 24 hours, but it took about three months to get around to the last few bits (like decorating the unit), so don't complain if after one day you don't get something that looks like the unit on the left!Unfurl
