Set the motor mount retainer on top of the stepper motor and attach with 4 x M3 screws. Press-fit the 5 : 1 sun gear with the motor shaft axle to the stepper motor shaft. (note: the motor mount STL doesn't have the four holes in the plate right...
Step 1: Fill the cavity of the mould with Fimo or a equivalent polymer clay and flatten the clay e.g with a round pice of wood or core follower. To prevent the two clay parts from sticking together while making the key indentation, powder some talkum...
1. prepare all the material : An arduino sheildSoldering materials4 servo motors4 buttons120cm wires * 12 60cm wires * 8 2. Braid the wires This step is for better wiring management and for avoiding short circuits. Braid the 60cm wires...
The basic capacitor is done. This next section is how I built a motor drive to remotely position the capacitor. I decided to use a DC motor. Perhaps a stepper is a better idea, but for now I like this design. The motor I chose is overkill. It was...
Since we're going to actually hack a pre-existing product - a shop bought CNC engraving machine - the first step is to assemble the CNC engraving/laser machine - it comes as a kit with instructions of it's own (see below). The upright aluminium 2020...
After you apply the finish to the wood pieces, it's time to press in the acrylic tiles and assemble the stand. The acrylic tiles are press fit tolerances and don't require any adhesive generally speaking. A few of the tiles may need small amounts...
Next, we're going to start extending wires and mapping out where we want things to go. I like to add plenty of wire ahead of time and trim to fit as I go. Extend the wires coming from the power cord and solder the white and green to the proper sides...
The simplest of changes was to add a hot air exhaust port and duct. I chose Chardonnay because its oaky tones complemented the oak in the top. You can choose a nice red, just NOT MERLOT! This may look large, but I wanted to make plenty of room...
Once all the components are assembled the next task is to feed firmware into the microcontroller. To upload the firmware the most recommended method is to use AVR in-circuit programming (ISP) compliant adapter. This system is designed to work with standard...
For this project we use an open source Mosquitto MQTT broker. It is lightweight and is suitable for use on all devices from low power single board computers to full servers. Before we start installing, it's a good practice to update the system components...
It is a very easy, event-driven tool for setting up your own automation system. You may also find more formal and precise Node-RED definition on their website: "Node-RED is a programming tool for wiring together hardware devices, APIs and online...
Start by gluing together the screen mount and screen surrounds. You can always see how the parts go together in the FreeCAD model. Here you can see the 3 parts that make up the screen mount. All the other parts are hidden - by clicking on the eye...
The USB connector is a nice through-hole connector. Even though it has tiny legs, you should have no problem with it with your new surface mount skills! We've also extended the pads in opposite directions to give you plenty of space for the...
PCBs designed by our team are manufactured by JLCPCB - a hardware production company that specializes in batch PCB production. You can create PCBs with up to six layers, and order a batch size that fits your needs. Batch production is beneficial since...
Mounting:One hole sized for 4-40 screws (or M3). Screws and standoffs not included.Other Cool Stuff:There are test points a-plenty, just to help you troubleshoot stuff. Or you can solder wires to them and pull extra power lines off the badge...
