I live in Brisbane, Australia and the closest electronics shop to me is called Jaycar. You can find them all around Australia. Note that the official Raspberry Pi 3 power supply is shown in the photo. You can easily use a Raspberry Pi 2 if you happen to have one and you can always choose to connect via network cable in the ethernet port if you prefer.
It is a board that the guys at Codify have created as a project for themselves. Ben Parker kindly gave me a couple of these to use and demonstrate. The custom printed board is certainly much nicer than wires on a breadboard. Note that it does not use all 40 pins but it is fairly obvious where you line up pin 1.
As you can see in the next photo the two pins from the terminal block that you connect to 12 volt power to are at risk of shorting against the metal shield around the HDMI connector. This would be bad. I found the 12mm spacers were slightly too tall and the 9mm ones just slightly too short. A Nylon M3 Flat washer proved to be just the right answer to this problem.
I screwed the spacer and washer to the Codify board using a M3x6mm Phillips head screw Jaycar HP as you can see in the following photo. You should also note that I am not securing the other ends of the spacers to the Raspberry Pi board. The next item on the agenda is to look at the LED light strip.
The 12 volt RGB light strips seem to be popping up everywhere. The strips usually have a 3M adhesive strip on the back so they can be stuck to a wall or piece of furniture. Usually both ends of the light strip are terminated with a 4-pin plug. These allow you to easily chain them if you want to create a particularly long light strip. This will make it easy to attach the light strip to the terminal block on the Codify board.
The hole in the PCB lines up with the lug in the bottom of the case and holds it in place. You can see now what the assembled project looks like. The Codify board is a great size to just fit on to of the Raspberry Pi. I should point out now that the top of the Raspberry Pi case is not going to fit due to the Codify board. My next task is to connect the wires from the LED light strip to the terminal block on the Codify board. The labels on the board make it very apparent which wires go where.It is a Raspberry-Pi 3 powered synthesiser.
Why make this when I have other synths? Well, there are three reasons:. I used a R-Pi 3B because I had one. The unit is lightly loaded in operation, and a 2B would probably be OK. Sound Card. Again, it was because I already had it.
To bring the voltage down to R-Pi voltage I bought a cheap adjustable 5V converter. Break-out Board. It has I2C connections for the display, and 10 inputs for the various controls. I used three EC11 encoders to provide the operator interface. They can be turned clockwise and anti-clockwise as well as incorporating a momentary push switch.
Each EC11 needs 3 inputs to the computer. I built a case using my 3D printer. I downloaded and compiled the first stable version 2. That version is not available via the Raspbian repositories yet. This is the tricky bit. Getting a good-sounding soundfont is not easy. I had to install CC2 breath modulators for each instrument, as the originals used CC11 expression for volume control.
I used Polyphone for that process. I downloaded the latest Bluez 5. I needed to change the symlink for bluetoothd to get the correct version running the symlink was pointing at the old version.If you're just here for the absolutely-totally-not-supported agent, you can download it here. We do demos with. Unfortunately, the Linux builds don't work on a Raspberry Pi.
Probably not a surprise.
Running a VSTS build/release/deployment agent on a Raspberry Pi
BUT, in typical recent-Microsoft style, the agents are open source! And they're written in C for. NET Core!
Thankfully for everyoneI didn't have to write any code, because Edward already did that for me. He had a pull request already in the works don't be surprised if that link breaks soonso I just grabbed that PR and compiled it on my Pi. The first was the configuration and run scripts. I'd just compiled the pure, unadulterated agent. I imagine the scripts aren't totally necessary to run the agent, but I'm lazy. Now, I could run config. Did you know the exact same agent is used for builds, releasesand even targets in deployment groups?
I really just wanted to use the Pi as a machine to deploy toso I reconfigured it as a target in a deployment group. I configured the agent as a deployment group targetran it using run. All that's left now is to create a basic release definition using the Deployment Group the Bash script is just a hello world at this pointand run it! Yep, even if I have a single bash script in my build or release, it runs that baby through node.
The second missing bit is a packaged version of node. Remember that externals folder?
Turns out there's a known version of node in there that the tasks use to run. Which poses a problem - the versions that come with the supported agents won't work I tried.
They're for other OSs I mean, don't get me wrong, it's pretty cool being able to deploy directly to the Pi using an agent like this, but what if you have hundreds of devices, or you're actually deploying to 25 light globes or a refrigerator?
That's what it's for after all. Awww Yeeeaah. That's right. So it should be totally possible to compile it for the Pi, right? Well, yes, but there were a few changes needed.

Missing bit 1 The agents you download from VSTS include a few things that this compiled agent doesn't have. Deployment agents A small aside. Yeah, we're big into reuse. What's the difference between those three agent types?

The instructions for both are the same. By the way, on the latest raspbian, it works out of the box. No need to install anything. Look for the device ID, which is in the format x So to connect the output of the LPK to the output of the Emu, just go:.
Naturally, we will want this connection to happen automatically every time we start the Pi. Of the several ways to do this, I opted for the laziest, which was to make a root crontab. This entry was posted on February 8, at and is filed under Zzzzz. Do you run it on battrery for me it would make just any sense for mobile usage of my mini maudio and i.
Hi Niels, I have not run it off batteries, but I know it is possible with a suitable battery clip. The reach is long enough. I'm sure there's an even cheaper ay, but I had all the ingredients available, so it was free.
Thank you for your fine work. This was extremely helpful. I am now able to get my OP1 to play nicely with my circuit and organelle. BTW your Tempest guide was masterful. Life and all that…. Great, thanks! Although having bother getting the frontal to work, the MIDI ports of my devices seem to jump around every time I reboot! Thanks for this!
I have plans on doing something similar. One question though: was midi channels a factor of the alsa setup? Or did you set the outgoing midi channel directly on the lpk? Great job, thanks! Do you know if is possible to send messages to change the emulate instruments. Thanks in advanced. Thanks a lot for these instructions, however they did not work straight away for me for a few reasons:.The Raspberry Pi was first introduced to the public in as a small credit card-sized computer with advanced features that you see on larger PCs, including USB ports, internet connectivity and HDMI capability.
Throughout the years the Pi has evolved to keep pace with current technologies on the market, including VPN technologies. What is a VPNyou ask? VPNs stand for virtual private networks.
What they do is that they create an encrypted tunnel between your computer and the network you are accessing services from, either through a government-made encryption device or application.
I happen to like VPNs because they protect my computers and my private network from illegal government spying and data theft. Coupled with antivirus suites, this provides a robust form of security that keeps your network private and secure.
The Raspberry Pi is perhaps one of the ultimate expressions of taking technology to the next level. As opposed to using large form servers where you would need to shell out hundreds of dollars, here we will do a rundown of the four steps on how to set up the Raspberry Pi and run it as a VPN server. This tutorial assumes you already have a Raspberry Pi computer with the Raspbian operating system installed preferably the Stretch or Jessie versions.
On my path to make a Pi a VPN server, I had to create a double-hop connection in order to make this process feasible. Double-hop connections essentially doubles the layer of security your server will provide. When choosing a VPN service, I picked the one that had a large amount of servers within its inventory that is arrayed worldwide.
How to create a VPN Server Using a Raspberry Pi
One of the other criteria that I had in choosing a service is that it supports the OpenVPN protocol, which is the current standard in secure communications. ExpressVPN has a large fleet of servers, and is reputable in its privacy policies. I downloaded ExpressVPN and installed the app into Rpi, which is already a fairly lengthy process itself. Once you have the correct Raspbian OS, you will need to have an Ethernet connection between the Pi device and your router, and configure your interface with the eth0 argument.
If on the other hand you do not have a direct connection to the router, you will need to configure it as wlan0 instead. SSH server mode is required for this evolution, which is enabled through the Interfacing Options menu. Terminal users also have the option of inputting this line in the terminal:. When the terminal comes up, enter:.
There will be a prompt following this pertaining to updates and dependencies. Accept them all and wait a bit until the installation process kicks off. The PiVPN installer will display via a graphical interface.
You need to let the installer set a logical static IP address for you unless you already have one on hand. This is the part where you will need to choose between the eth0 or wlan0 interfaces — the former which serves as your hardwired connection and the latter for your Wifi functionality. The RPi will take a moment to configure and calibrate itself, and you will see visible activity within the interface through scrolling lines of text.
The PiVPN interface will then prompt you to select a local user in this instance pi will show up as your local user name. You will have the option of adding on other users later. After the installation is done, you can enter the pivpn command in the terminal and type in other options, such as:.
In this step, you will need to open up a communications port in your RPi. You will get a prompt asking if you want to enable unattended upgrades. Choose Yes as your option. When it comes to security, you do not want to skimp out on upgrades. Not enabling them gives hackers incentive to run port scans and breach your network.Logout Register. PasPi as a hardware VST host? From watching omenie's and echolevel's excellent work I think it'd be possible!
I decided to write down my conclusions to see if I can get any input from you guys. What do you think about the following setup? Velocity sensitivity?
Steinberg brings VST to Linux, and does other good things
Tue Aug 28, am Sounds like quite a project! I'm sure it's possible, in terms of getting all the VST API calls hooked up, but I suppose then it's a sliding scale of resources vs capability.
I can't offer much in the way of practical advice, except for the fact that I'd imagine OSC would be a much better way to control this. But Lemurs are stupidly expensive and now out of production, I thinktherefore at odds with the idea of a RasPi-cost standalone VST machine. It's what I plan to do, anyway Good luck!
I got this idea after deciding to buy an electronic drum kit which has crappy onboard samples most of them do, so people play them through software. But I think I'll purchase the Pi so I can start learning hands-on.
I'll keep following everyone's progress. Thanks for sharing! PS: If USB latency can be resolved in future updates, this would really make things easier hardware-wise!
Wed Aug 29, am Thanks! That does look like good solution for clear analog sound. Would it be possible to power up both devices off one 5v adapter to keep things in one box?
PS: I just found a cool piece of soft, Oracle VirtualBox, which should allow me to install Raspbian and start learning it before I actually get the Pi in my hands!
