As I mentioned earlier, 3D printers have serial but the data is communicated via a converter chip to computer-friendly USB. Most small controllers can not act as USB host so we need to hijack the serial before it gets to the converter chip. Looking at...
Now we start adding the components for the material feeding system. These include the hopper, the hopper inlet and the joint body that connects the hopper with a material reservoir. There will be also a motorized feeding system. Prepare: 6 pcs M3 Square...
Your hacked and sweetened Bubble Blaster is ready to go! Now you can incorporate it into any kind of project you want! Here's a list of some example projects I have done for inspiration! Hopefully i will get around to posting full how-to articles for...
Install the Arduino IDE and ensure that the ESP32 Board manager is installed. If you're not sure how to do this, you can refer to this article: Installing the ESP32 Board in Arduino IDE.Make sure you have the DFRobot/DFRobot_RTU (github.com) and cdjq/DFRobot_EnvironmentalSensor...
An overview over what components and tools were used in this build. More on how the parts were selected in the next step. The components are divided among what's needed to make the PCB which acts like the watch movement, and the watch body itself. Electronics...
You can check out the interactive model for the Trash Printer on the SketchUp 3D viewer, or download it from the SketchUp 3D warehouse. You can use this model as a reference to see how all the parts go together, and you can also use it to modify...
This flow cell generates electricity by differences in electrode potential in manganese dioxide over a PH gradient, like a fuel cell that uses acids and bases instead of oxygen and fuel. This type of technology, albeit probably with different electrode...
Effective Bardware Based Stepper Motor ControlIn my quest to derive a robot control scheme from scratch, I've been working to figure out how to control a stepper motor. Stepper motors are great because they're cheap, relatively simple to control,...
Step 2: Sensor BoardsCongratulations -- if you've successfully soldered the motherboard, then you'll likely have little issue putting together the sensor boards. They're very tiny, and about a 2 hour build per board. Because the process is similar for...
Step 2: Working with Robot Simulation using R.O.S and GazeboAfter designing the robot 3D model, the next step is to simulate the robot. I have describe complete simulation of this robot from scratch in the book. The simulation is done using R.O.S and...
Hello there!In Christmas I had a little more time to improve DIMER, improvements have been mainly two; motor drivers and two potentiometers to know their position and power programming.Drivers:In Bilbao maker fair another maker told me he had just found...

STEP 4 Box it togetherOnce the shield board is ready, take the box and start to laid out all of the remaining components and plan where you need to drill holes and what shape and size. The best way to cut holes is with a small pocket knife (at least...
