However, while the Raspberry Pi undeniably ranks as the most popular and well-known SBC, there are loads of options. Check out the best Raspberry Pi ford f350 wiring diagram schematic When selecting a Raspberry Pi alternative, think about what you plan to use your single-board computer for.
This ultimately determines which SBC is most appropriate for your needs. Whereas the Raspberry Pi 3 is suited to many applications, video game emulation, for instance, is decidedly choppy for Dreamcast and Nintendo 64 games. However, Orange Pi offers loads of hardware options.
You'll even find several accessories such as Orange Pi Prime cases. You can run Android, as well as Linux. While the Raspberry Pi caters to both power users and beginners, the Arduino is mostly a development board. Feeling overwhelmed? Snag an Arduino kit and start with a simple task such as blinking an LED. Ultimately the Raspberry Pi and Arduino are not the same, one being a microcontroller, the other a single-board computer.
Still, there's some overlap in their uses, and the Arduino is an awesome choice if you don't need the GUI features of a Pi. As Trusted Reviews revealed, the Asus Tinker Board delivers superb performance with exquisite hardware.
Moreover, software support is a bit hit or miss. Despite a few concessions, the Odroid-C2 delivers a performance boost at a price on par with the Raspberry Pi 3, making it a true potential Pi killer.
In fact, the only benchmark where the XU4 did not outright win was in John the Ripper tests. Aside from that, the Odroid-XU4 trounced the competition. Ultimately, it's ideal for loads of projectsfrom gaming and HTPC use, to cryptocurrency mining.
Plus, the Odroid XU4 runs Android extremely well. Like the Cubieboard the BeagleBoard X15 does not come cheap. However, it runs pretty much any Linux distro you throw at it, as well as Android, and is capable of running P at 60FPS.
Plus, the X15 houses two Ethernet ports. The Odroid H2 arrives as the first x86 single-board computer from HardKernel. It's compatible with NVMe M. Since the Odroid H2 touts x86 compatibility, it can run virtually any operating system. It's a fantastic board, though the Odroid H2 price might prove a deterrent for some uses. Still, if you demand top-tier performance in a tiny form factor, the Odroid H2 vs Raspberry Pi is a no-brainer.
Similarly, the LattePanda Alpha is a nifty maker board rocking x86 support. As such, the LattePanda can run Windows 10 as well as virtually any Linux distro you throw at it.Analog modular synthesizers and embedded systems are currently enjoying a large amount of attention due to the arrival of extremely cost effective and unbelievably powerful devices. This article will describe the process of building a Eurorack FM oscillator using Csound's foscili opcode.
The Eurorack modular synthesizer format was started by the German company Doepfer in The majority of modules on the market have an aluminum faceplate but for DIY projects, plexi glass, PCB material, or even cardboard will suffice.
To connect a module to a standard Eurorack case's power supply, a ribbon cable is used. The cable can have a 10 or 16 pin connector. Arduino is an open-source micro-controller platform used by hobbyists and developers for prototyping and designing interactive tools, products, artworks and general household gizmos. The platform emerged from Ivrea, Italy in to aid student physical computing projects.
It has since blossomed into an array of very affordable micro-controllers of all shapes and sizes. There has been a growing community of Arduino users who use the platform to build custom MIDI controllers using the vast array of sensors and technologies readily available from online suppliers like Sparkfun .
A perk to Arduino's open-source philosophy is the freedom to build Arudinos yourself in your own preferred format. The following schematic fig1.
Introducing the MPA Platform
It will require a timing source 16MHz crystal oscillator and regulated 5V power source to complete the basic stand alone circuit. A small flathead screwdriver will easily remove chips from the board. Be aware to match the notch on the IC with the notch on the socket, and be gentle with the legs. Pins 23 to 28 are the Analog inputs A0 through A5 respectively. These can receive variable voltages from 0V to 5V. Figure 1.
ATMega chip circuit with analog inputs from 3 potentiometers and 3 control voltage sources source must be unipolar positive V. Control Voltage CV standards for Eurorack are bipolar signals that range from The analog to digital convertors ADC's on the Arduino can receive only unipolar positive voltages up to 5V.
This requires our CV source to be biased into a positive signal before being accepted by the Arduino chip. An operational-amplifier op-amp can be used to perform this task.
25 Raspberry Pi Project Ideas to Put Your Pi to Some Good Use
These attenuation networks scale any incoming signals to a little over a quarter of the initial input voltage, which is then biased by the op-amp. The op-amp outputs then lead into an optional protective circuit, which stops any negative voltage bleed from reaching the Arduino. The maximum voltage is also limited to 5V.Here are some great projects that will help you start writing code and get going with digital making.

Rather than deal with designing and fabricating printed circuit boards PCBsI wanted a way to quickly take circuits developed on a breadboard and implement them in my Eurorack setup. Enter the mighty Perma-Proto board, from Adafruit :.
I have used these Perma-Proto boards on a number of other, non-synth projects before. They are high quality in construction with thru-plated holesand they offer a nice layout, with strips running down both sides for power rails.
Adafruit also offers a full-sized version of the board, so you could get one of those and cut it down to exactly Eurorack size and gain another 10 rows or so of holes.
But my goal was to make simpler designs with this setup anyways, so I hoped I could make the half-size version work, with less effort and less waste.
Then we thought about how people actually prototype — usually starting with a solderless breadboard and then transferring the parts to a more permanent PCB. Read more.

Enter the mighty Perma-Proto board, from Adafruit : I have used these Perma-Proto boards on a number of other, non-synth projects before. After settling on the board, I needed to figure out a few other construction basics: How to connect power from my Eurorack case, following some available Eurorack standards What kind of jacks and potentiometers I could find that could solder directly to the breadboard avoiding a tangle of wire leads going between the board and the panel, if possibleand where on the board could I solder them?

Video, embedded below. In normal use, he can control the servos inside the hand simply by thinking about moving muscles. After experimenting a bit with an old hand, he discovered that the amplifiers in the prosthesis could produce a proportional control signal based on his inputs, and with a little help from synthesizer manufacturer KOMA Electronikhe came up with a circuit that can replace his hand and generate multiple control voltage channels.
Plugged into any of the CV jacks on his Eurorack modular synths, he now has direct mind control of his music. We have to say this is a pretty slick hack, and hats off to [Bertolt] for being willing to do the experiments and for enlisting the right expertise to get the job done. Interested in the potential for EMG control? While step one is usually to build something, anything that makes sound, a natural step two is to build a looping device to extend and play with those sounds.
He plugs in a thing, records some tunes, and the resulting loop gets divvied up into eight equal pieces. He can cut the loop together live using the eight buttons to jump around between sections.
It supports unlimited overdubs, although too many will cause clipping. But hey, that just means free derivative sounds.
The looper records its audio to an SD card. Since this is typically a slow endeavor, [Cutlasses] used two circular buffers. One reads audio, and the other writes it. This took a lot of trial and error, which he may have to repeat with future SD cards.
Jog past the break to watch [Cutlasses] demo his looper with a kalimba and a DIY noise box that uses a string bow to make metal tines sing. Feeling out of the music-making loop? There are slightly easier ways. Modular synthesizers have been around since the early s, delivering huge tonal possibilities from their impressive and imposing patchbays.
Inthe Eurorack standard was launched, and has become the go-to choice for enthusiasts new to the world of modular synthesis. The unit packs plenty of connectivity into an 8HP wide panel, with four gate inputs and outputs, four CV inputs and outputs, and serial MIDI in and out. Thanks to its Bluetooth connection, Motivation Radio makes it easy to pass note and gate data into a Eurorack setup, and can be used with the wide variety of tablet and smartphone MIDI software on offer.
Video after the break. However, not everything on a modular synthesizer build has to be inordinately complicated, a mess of wires, or difficult to understand.
The device has 12 channels, each responding to a single MIDI note. A note on message is used to set a gate high, and a note off message to set it low again. This allows very fine grained control of gates in a modular setup. The device can also output a variety of sync signals controlled by the USB MIDI clock — useful for keeping your modular rack in time with other digitally controlled synths.
All the required details to build your own are available on Github. Eurorack has taken over the synthesizer community, and hundreds of people are building their own eurorack modules. The basic idea of a Eurorack sequencer is to somehow store a series of values and play them back repeatedly. Connect that sequence to a clock, and you get the same pattern of sounds out of your synth. This can be done digitally with a circular buffer, in the analog domain with a bunch of FETs and caps, or in this case, on a piece of paper glued to a stepper motor.
The key bit of mechanism for this build is a stepper motor with 96 steps per rotation. This is important, because the module is controlled by a clock pulse from the sequencer. The electronics for this build are surprisingly simple, with an Arduino taking in the clock pulse and sending the step signals to an H-driver.
The motor spins a paper disk, which is read with a photoresistor and a LED. You can check out the video of this build below.If you bought a Pi and wondering what should do with my Raspberry Pi, I have got your back.
