Take control of your CAN bus by deciding how signals move between OBD connectors with the OBD2 Breakout Board. This breakout board is designed to simplify OBD2 device development. Users can install a jumper wire between rows to create connections, among many other tricks.

The OBD2 Breakout Board can be used to function in several different ways by how the user alters the signal routes through the system. Users can use this device to create a sniffer to watch traffic, or create an emulator by connecting 2 OBD2 Breakout Boards together for developmental purposes. Users can also create a man-in-the-middle by placing the OBD2 Breakout Board in between the host and another device.

Each product comes with a fully assembled OBD2 Breakout Board, documentation card, official sticker, and jumpers. The product features the following:

• A 12V Input Power Source
• CAN Termination Resistors
• Junction Blocks
• One Green LED
• One Input OBD2 Connector
• Power Jumpers
• Two Output Connectors

The OBD2 Breakout Board might be the missing piece for your next project, so be sure to check it out!

Every modular system needs a place to bring all the bleeps and bloops together, to make a happy sonic family. The Nerve Center is a simple, adaptable example of a DIY mixer with 4 inputs and only 10HP of eurorack real estate required. If you’re new to soldering, and need a mini mixer, this is an ideal starter kit, so lets take a look at what it’ll do!

This mixer has 4 mono inputs or 2 stereo inputs, depending on what you need – providing a single or double mixed output. Control panned signals, individual instruments or CV signals – giving rise to the merging of a wide range of modular goodies. The individual output volumes are attenuated by four faders, and each channel can be muted – indicated by a little LED on the channel fader.

The mixer has a 1:1 gain ratio, but this can be adjusted by replacing some of the resistors – more information will be provided by the seller. The kit comes with all the PCBs, connections and components you need to make a finished mixer, with comprehensive build instructions available from their website – there are 3 PCBs and around 50 components to solder.

The Nerve Center is made by CCTV who are based in Canada. Check their shop for more musical products!

Polyphonic synthesizers have long been the ultimate in electronic music making, with early incarnations costing thousands and taking up huge spaces in the studios of the 1980s. The TSynth has just been released, and is one such polyphonic synth which looks and functions like a polyphonic monster at only a fraction of the price and size!

The TSynth is a Teensy-based DIY synth kit which has 6 note polyphony coming from two oscillators, with PWM (Pulse Width Modulation), a pitch envelope, two LFOs, Ring Modulation and a stereo chorus! It also allows you to save and recall patches, so your beloved sounds can be saved to internal memory, and you’ll find the full list of features on the TSynth product website.

The TSynth comes in PCB form, meaning you’ll need to source the components and an enclosure to fully complete the build. You might like to check the build guide which goes into step-by-step detail about the components within and construction of the synth. Note: You’ll need the Teensy version 3.6 as the processing power behind the TSynth, the latest version is being worked on.

The TSynth is the first product made by Electro Technique who are based in South Korea. Check out the demo they’ve made here:

Many synthesizers come with built-in arpeggiators, but for those that don’t the ARPIE is just what you need. It comes in a pocket sized package, and runs off a battery or a power supply  – and is absolutely packed with features for undulating melodic arpeggios! With a customer base including Jean-Michel Jarre and Vince Clarke, you can be sure the ARPIE is a potent creative  force in any electronic studio.

The ARPIE is designed by Jason Hotchkiss, and is so feature rich it has a 40 page manual! You’ll find controls for transposing, pattern, rate, span, velocity, length and various sync modes for external gear. It features both a MIDI in socket, and a MIDI clock in so you can have one source controlling the tempo, and another controlling the arps!

This is the ideal addition to any synth which doesn’t have an Arpeggiator – that includes the mighty DX7, and many of the early FM Synths. Even if your synth does have an arpeggiator, chances are this one has way more options and features!

This ARPIE is sold by midierror, and comes fully constructed and tested. If you prefer a kit version, you will find them here. See what it can do below:
