Boris Landoni from Open Electronics writes about a new open source energy meter project:

In the first installment, you had the opportunity of learning about our energy meter, and of learning about its details, with special attention the technical ones. Our energy meter is based on the coupling – by means of two measuring transformers – to an integrated circuit, that enables the detection of the values as for voltage and current, in addition to the corresponding phase angles, so to be able to know the real, the reactive and the apparent power, in addition to the phase angle (cosφ). We developed a software to be paired to our measuring board, so that it may be used for the configuration and calibration of the integrated circuit, and for the real-time display of the electrical measurings that it has carried out.

agilent_53131A_53132A_Timebase_us_oven (3)-600

Gaurav Singh made an open source 53132A OCXO Ultra stability time base, that is available on github:

While i was working with my own GPSDO project. i need to have a frequency counter with descent stability so purchased my self a Agilent 53132A which is a 12 digit frequency counter, big brother to 53131A 10 Digit Counter. Both are really nice units.
But they unusable standard Timebase. So optional oven oscillator time base need to purchase. but 53132A and 53131A both unit are no longer available for sale and neither of the Time base upgrades.

canable

An open-source USB to CAN adapter:

It supports CAN bit-rates of up to 1 Mbit/s. The product comes with an open-source SocketCAN driver software. It features a Micro-USB connector and a 4-pin screw terminal with CAN_H, CAN_L, 5-V supply, and ground. The CANable device is a hardware clone of Eric Evenchick’s CANtact project, an open-source USB-to-CAN hardware adapter

Traktorino, an open source DIY MIDI controller

Traktorino

Here’s an Arduino based open source MIDI controller by Musico Nerd, the Traktorino:

The Traktorino is a powerful low-cost DIY MIDI Controller. It is based in the Arduino platform and it comes in DIY kit, or assembled. In its core, there’s a shield that connects to an Arduino Uno, which uses open-source code, making it totally hackable.
The Traktorino is a MIDI class compliant device, designed for controlling Traktor. It has several features and custom made mappings, so you can take the most of the software. However, it can do much more than that. The Traktorino can control any software that accepts MIDI, like Ableton Live, Serato, FL Studio, Logic, etc
