For those who own MPCs (or MPDs for that matter!) beatmaking is a way of life – a time to escape the outside world and get absorbed in chopping samples and laying down some big beats. Well, if you have an Akai MPD this Replacement Knob Akai MPD (Pack of 4) is a nice way to embellish your beatmaking with a set of four colorful knobs – to liven up it’s look, match up with your audio workstation or replace any which have been lost or broken.

They’ve been 3D printed using hard plastic PLA, and were originally designed to match with the Ableton Live color scheme in order to help MPD beat making flow more easily. Replacing your existing knobs shouldn’t be too much of a problem, just a carefull pull on the originals and then press your new colorful caps in their place! Choose from a mix of colors or use the drop down menu to pick the exact combination you need.

These MPD knobs are sold by Rick’s Music Store who’s based in Canada and sells more music goodies; including sliders for an MPD and a nice stand for the Moog Werkstatt.

Listening to music made on the original hardware is an audiophile and music nerd’s dream! Great news then that the mt32pi hat for zero 2w model Raspberry pi has just been released, giving us the opportunity to put our ever-growing Raspberry Pi collection to work in playing MIDI music from original system engines. If you’ve ever gamed on an ao486, Atari ST, Amiga, or x68000, then you’re in for a treat!

Designed for the new Raspberry Pi Zero 2W (but it will work with other models), this unique device will connect to your MiSTer FPGA to enable you to listen to classic MIDI music from a whole host of vintage video games, as well as being munt and fluidsynth compatible. Using the hat means you can connect a Raspberry Pi directly to a MISTer machine using just a USB3 male to male cable. Incorporating the Raspberry Pi Zero 2W gives it an incredibly small form factor, capable of being transported, affixed, and accessed easily.

These days, there’s really no excuse to not be using some sort of password security system – and the Mooltipass Mini BLE Authenticator is a great choice if you’re looking for one. Reusing passwords is just begging to be a victim of a credential stuffing attack. With literally hundreds of millions of username/password combinations floating around online, every single Internet user should have at the bare minimum a software password repository. These are reliable and time-proven, but they do have some drawbacks. Any device that can’t install the required app or browser extension has to have password manually entered. If you lose your phone or have to factory reset it, it can be a pain to get signed into your phone and get everything set up again. Or you might have more stringent requirements due to work or personal preference.

The Mooltipass Mini BLE Authenticator is the latest iteration in the Mooltipass series of hardware security devices. I’ve had a Mooltipass Mini (non-BLE) for a number of years now, and while I use a software-based password storage system primarily, I use the Mooltipass for a number of security-critical files and passwords. Knowing that physical access to the device, the smart card, a and my PIN are all required to access the device gives me great peace of mind. The Mooltipass is also a fully open-source project, meaning you can look at the code yourself or have it audited for security issues. The new BLE design segregates the BLE processor from the crypto processor, providing another layer of separation. All passwords and other data is stored using AES-256 encryption, which has no known feasible attacks – even by nation-states with huge amounts of computing power and time.

The new Mooltipass now integrates BLE, making it even easier to use with phones/tablets and many other devices. Whereas a USB OTG cable was needed beforehand, now a BLE connection can securely enter passwords for you without having to carry a cable around. Combine the Mooltipass BLE with a FIDO/U2F device (like the Yubikey) and you can have ultimate access control to your most important online data.

At this very moment, electromagnetic waves are flying around our residences, coursing through our bodies, and interacting with us in countless ways. It’s a marvellous unseen world, strange and amazing enough to make one at least sympathize with those that express fears over such phenomena.

While not always intentional, all electronic devices emit electromagnetic radiation/waves to one extent or another. If you’d like to explore the electromagnetic output of everyday objects, then check out the Circuit Surfer from Fusco. This device uses a copper coil inductor as a sort of electromagnetic microphone/short range antenna, which when held up to an electronic device emits interesting, and generally high-pitched, noises.

As shown in the video below, the face of a cell phone makes different noises depending on the sniffer’s position. A fan makes a low drone sound, while a traffic light buzzes when illuminated. A flashing bicycle symbol is especially entertaining as it blinks/beeps in a predictable pattern.

The device is powered by a 9V battery, and features a 3.5mm jack for audio output. While interesting, you’ll want to keep the volume at a relatively low level when using it per its  unpredictable crackling and high-pitched squealing.

This Envelope Generator and Low Frequency Oscillator (LFO) module is the perfect compact companion to your Eurorack setup. Command the envelope of your frequencies with ease and precision using the high-quality potentiometer controls, and get making some incredible sounds!

An envelope generator controls the volume of an incoming sound – essential in any Eurorack setup. The front panel has three dials, which form the shape of the outputted sound – the first dial is the attack, or rise time, which controls how quickly the signal reaches its peak volume. The second dial controls the sustain, which is how long the signal stays at its peak and the third dial governs the release time, which is the speed at which the signal returns to 0. There are also outputs for the envelope as well as it’s inverted signal.

Using these parameters, you can create all sorts of exciting sounds using many different methods – like slowly evolving pads or short sharp percussive stabs. Combining this envelope generator with the rest of your Eurorack kit will make the perfect environment for some creative sound signal generation! This device can also be patched as an LFO, allowing for even more exciting possibilities. Alongside being a brilliant module, it’s also got a beautiful design!

Blacknoise is an independent company based out of Dijon, France. They have a lot of experience designing Eurorack modules and aim to develop the kind of products they wish they could use.
