Gantry Assembly 2 hoursThis is the estimated time it will take to assemble the Gantry.Step 1: Assemble the Gantry PlatesGather and lay out all of the parts. You will need:Two Gantry PlatesEight complete V-wheelsEight M5 x 30mm screwsEight M5 locknutsEight...
Here’s the camera holder from the previous step:Small, neat, secure, easy to install – perfect for the right camera. What is the right camera? It needs to be a reasonably small camera that will lay flat/parallel on the wooden board when you insert the...
At this point I assume you've already figured out how to get the PCB. So below are purely the component side:Cherry MX switch. Mouser. They have pretty decent stock available for Black, White and Blue color. apart from that you probably need to find...
There are four main parts of the circuit board. We have the atmega328p microprocessor. This is the same as is found in popular arduino models. This is the brain and will communicate with a real time clock (RTC) module, process the time, and display...
This step in the Instructions is practically a project in itself. The Throat version of this project requires something to hold the mike against the neck; this could be the collar of a costume, though in many (if not most) cases a neckband will be needed...
The videos on youtube discussing state space control make it seems simple: choose where you want your poles and as long as your system is controllable, you can find a feedback matrix that will get you where you want to go. In practice, there are plenty...
Parts Selection I would say in general there are four categories of parts that you need to manage where some are customizable ordering-wise while others are fixed. The PCBsThe Electronics BOMThe Miscellaneous BOMThe Housing The PCBs Honestly the...
With PWM we face some strong limitations: if we use software PWM we can use any GPIO pin, but get a lot of jitter. If we use hardware PWM we are limited to very few pins and two channels, but get almost no jitter. This is were the DAC comes in. It let's...
As we've established in prior tutorials, every program written with the ESP SDK needs to have a function called user_init(). This function is called by the SDK once it has finished the boot process. Much of the code in our example revolves around getting...
The conversion to MSX1 by adding PPI, keyboard and BIOS/BASIC ROM gives you an advanced version of BASIC which includes commands for the screen modes, graphics functions like circle and line and the Music Macro Language (MML) for writing music....
The internals of the AUV performed the heavy work of actually taking water quality measurements and controlling the submersible's buoyancy. Evidently, it also required a sophisticated mechanical design to fit the necessary components into the confined...
Step 1: Gather Your Components Laser XY Scanner - BOM I usually like to source my parts from DigiKey, but the low-cost options on Amazon are hard to beat sometimes. This list is just one of many sources for each component in the BOM. There are of...
Through Hole Technology (THT) versionThis is how I built the Through Hole Technology version Make a double-sided fibre glass PCB (see front- and back- PDF files below). There are several ways to do this. The way I do it is to print the front and back...
