3D Scanner.Gerbers2

2 layer board of 3.94 x 3.94 inches (100.2 x 100.2mm) 3 boards will cost $77.70

3D_Scanner LINK TO PROJECT

It is a simple Arduino-based gadget which automates images taking for photogrammetry (3D scanning from many images). It slowly spins a round platform using a stepper motor, and regularly triggers a camera shutter and optionally an external flash. In particular, it can be used with Canon DSLRs running Magic Lantern firmware in a Full Resolution Silent Picture (electronic shutter) mode - with an external flash.

The gadget uses a small Nokia LCD (~3$ on ebay) and a 4x4 keypad (1$). Internal components include Arduino Nano with a mini USB connector (~4$), DRV8825 Stepper Motor Driver (1.40$), and two optocouplers.

DIY LiPo Charge/Protect/5V Boost Circuit by GreatScottLab

2 layer board of 1.72 x 0.77 inches (43.7 x 19.5mm) 3 boards will cost $6.60

He will show you how he combined a couple of ICs in order to create a charge/protect/5V boost circuit for a single cell LiPo battery. Along the way he will show you how he designed the PCB, how he ordered it and what kind of problems occured while soldering the components and testing the circuit. Let’s get started!

Instructable for his design and build with howto and BOM

Orange PI zero Echolink node

2 layer board of 1.90x1.82 inches (48.13x46.15mm). $17.20 for three

Micro EchoLink node based on Orange Pi and a transceiver DRA818U I want to introduce you a project of the French radio amateur F5NLG. This is the Echolink / FRN system node based on Orange Pi Zero and the DRA818 or SA818 transceiver.

Stepper Breakout

2 layer board of 5.30 x 1.35 inches (134.6 x 34.3 mm).

2 layer board of 5.30x1.35 inches (134.62x34.34mm). $35.80 for three.

What do you do when you need to drive multiple stepper motors with the same step, direction, and enable pins? If you’re in RepRap land, you just connect two steppers to the same output. This is dumb. I have a project that needs to drive four steppers for the Z axis of a printer. The easiest solution? Break out the Step, Direction, and Enable pins on an A4988 socket to four different motor drivers. This is the project that does the job.
