Atomwear By Shuwen Liu

Do you love building custom electronic projects? Then you have to think about this amazing Atomwear. The master brain behind the Atomwear is Shuwen Liu. Atomwear system is a micro, modularized open source wearable system which includes Bluetooth low energy connectivity and a wearable strap for your creations. It is fully open source, micro, modularized, open source, wearable BLE device for DIYers.

Atomwear is a BLE product based on a Nordic BLE chipset which enables to build custom wearables easily. You can design many micro sized modules which includes including BLE MCU module, battery charger module, acceleration sensor module, baroceptor module, temperature sensor module, gyroscope module, OLED display module, heart rate sensing module,etc. The possibilities are endless.

Atomwear can be used to pedometer, motion tracker, temperature humidity, Bluetooth intelligent anti lost locator, e-compass, pressure and altitude detection, gesture recognition, HID Input and Bluetooth Smart Becon.
Even though you are not an electronic engineer, you can still make a wrist strap by yourself by just assembling Atomwear modules with FPC and assembling them into a rubber ring.

Affordable Flexible Open 3D Resin Printer
LittleRP is a standardized, affordable, open solution for resin printing. This open 3D resin printer is easy to self source and makerspace friendly.

Affordability, Flexibility and openness are the three fundaments of LittleRP. We have only few inexpensive resin printer options in the market. LittleRP is specially designed to be affordable in acquiring, inexpensive in operating and flexible to fit a variety of needs that encourages 3rd party vat designs, linear motion components and DLP light sources. It is available in a range of colors and is ideal for 50-100micron layer heights.  This is an open hardware project, so you will have the access to every STL, every measurement, every lasercut file, BOM and build documentation. For future modifications or any assistance the team of LittleRP is happy to answer your questions.

The kit includes all the equipment within U.S delivery. Projectors for delivery outside U.S are not included. To assemble the parts there is no need of soldering. The software used to slice STL models and feed them to LittleRP is Slicer/Controller. Autodesk® Meshmixer® is suggested to be used for hollowing, but I believe you can use Slic3r to hollow the objects. For adding extra support structures to the model can be performed by Creation Workshop (is free to download, but it not clear if free and open source) and B9Creator® Layout software.

Are you a fan of 3D printing then you shouldn’t miss this opportunity to back this project. Watch this video before pledging on this campaign.

USB Rechargeable Soldering Iron
Melts Lead-Free Solder! Lasts hours and recharges from a USB port! Open Source Hardware, lightweight, fast, cordless, easy-to-use!

First found on Instructables:

Solderdoodle is a nifty tool with a rechargeable battery and open source hardware. It is portable, cordless and lightweight. It has heats up to 700ºF in just few seconds. It can be recharged from a USB Port. As it is portable, you can take it anywhere and charge it with one of these: Laptop, USB Battery, Wall Adapter, USB solar charger.

Below is the temperature control of the Solderdoodle, which lasts more than 2 hours.
Solderdoodle Temperaure Control

Though you like your premium soldering iron, Solderdoodle Pro is a great one for quick jobs. It uses a high power charge controller from Maxim and battery that is used I Tesla electric car. The soldering iron tip can be replaced using off-the-shelf components.

Develop your own mini-camera

Does your project need a wifi enabled HD mini camera?  With this free and open source hardware available from Lamobo, it is now easy to create your own camera.

The Lamobo D1 is the smallest open-source development board, with a built-in HD mini camera. On first glance it looks like it just a pin hole camera, but this has the brains to control your project, plus provide decent connectivity. The wifi can either connect to your network, or can provide a access point so your can connect phone, table or laptop out in the field.

The camera records 720p @ 30fps, so will still get some respectable footage. For $89 the D1 Pro comes bundled with a 120, 160 & 210 degree interchangeable lens, perfect for every application. There are a large range of features you need to take a look at, like 20 GPIO’s on the pro version, that includes some PWM output. All these features can be controlled via your program running on freedom loving Linux 🙂

I am sure you will think of way of working one of these boards into your next project…
