All of my weekly posts in one place. There will be one post every week which appears in this category summarising my actions and thoughts for that week.
The final week task was to program a robot which would move by itself and avoid objects Unfortunately this wasn’t completed due to time constraints, although most of the code for the movements was completed and fully working The board was attached to the chassis with metal standoff – which did short the board out […]
Arduino LCD Displays Wire up the arduino using these following instructions VCC (Red) to 5V Ground/GND (Black) to GND SDA (Blue) to A4 SCL (Yellow) to A5 The code used was downloaded adn the library installed in the specific location. Ensure that the LCD drivers are included in the same folder #include <Wire.h> // Comes […]
What is a stepper motor? A stepper motor uses opposing electromagnets to create rotation. The different number of steps are determined by the number of poles on each the stator and the rotor. There are several different types of stepper motor, depending on the use case and the size that is required. The main types […]
Pulse Width Modulation Using ‘unsigned char’ to replace values > ‘unsigned char’ allows you to control all of the same variables in a sketch by only changing one value unsigned char DelayTime = 255; unsigned char LEDoutput = 2; // the setup function runs once when you press reset or power the board […]
Design Rules for CNC/casting Most important is to know your cutter shape and size. Any features have to be designed in accordance to the diameter of the cutter as this will restrict how far and deep the slots between features can be. Try and keep the cutter as big as possible as it will reduce […]
3d Scanning can be done in multiple ways and at multiple price points, either with handheld scanner for an iPad all the way up to full systems, e.g for car manufactures to scan clay cars. They also have different degrees of accuracy, with hand held scanners being less expensive they will also produce less detailed […]
The task this week was to program the board that we made using the CNC router. There are several levels to this week, some being ‘simple’ and some being advanced. The main goal was to upload some sort of program to our Echo Hello World Plus board and ensure that it completed the function that […]
The task this week was to create the schematic, board layout and then mill the simple LED circuit board. Autodesk Eagle is the circuit-board software that we used > Installing it was relatively easy as it was just a simple installation but to get the correct components for the FAB LAB, downloading the library of […]
Surface mount components are very common and are what the majority of manufacturers will use due to the smaller size, compared to through components. It seems fairly easy to use them, although the mounting of these components, via soldering is vastly different to through hole components. Through hole components have the obvious advantage of being […]
Task: Produce a press fit kit (accounting for kerf) using the laser cutter Making the Design The main aim is to use parametric design software to ‘simplify the process’. Being able to edit the sketch automatically by adding parameters and using these to dimension the sketch instead of manually changing them. First step was to […]
The task this week was to make on Fusion 360 a version of our tile, render it and display it as a pattern of 9. Method Start new sketch > Draw 100 x 100 mm square using corner to corner rectangle tool > Exit sketch Extrude 13mm with a taper of 4 degrees (minimum required […]
This week task was to create our own web page by either using edublogs or another website software. I chose to go with edublogs as they are supported by the university and therefore would have support available. Choosing a theme was difficult and I went through several to find the correct one, eventually choosing ‘Weather’. […]
