We had our weekly progress check with Dr Ho, who suggested with delve deeper into our design for the funnel again. Dr. Ho drawings. We taped the ledges we 3D printed to the wheel using masking tape, and held our funnel to the wheel to attempt to recreate our idea by putting pipette tips in … Continue reading Progress checking, wheeling

We finished assembling our Arduino kit today and tested it. We identified a missing component (a z-axis sliding plate), which we ordered today. We also coded the movement for the 3D printer using python. Finished Arduino assembly. Finished Python code to control movement of 3D printer. (Credits: Yuki) Additionally, our hamster wheel arrived, so we … Continue reading 3D Printers and Wheels

With the 3D printer machine built, we started assembling an Arduino kit to be used with the 3D printer machine. Process of assembling the Arduino, using parts provided by the Making and Tinkering Lab. With the ramp working, we did not see a reason to use the shutter that we 3D printed anymore. However, we … Continue reading Assembling the Arduino

We collected our 3D printed ramp and started experimenting with different ways to make sure the tips could slide down the ramp (i.e. changing the distance between the two blocks to see what the optimal distance to allow the tips to slide down by gravity is). During this process, we discovered that there is a … Continue reading Building the 3D printer frame

We collected the 3D printed parts of our shutter and started to assemble it. Unfortunately, as the 3D printer was unable to print the parts precisely, the dimensions of the screws and their holes were not accurate and hence incompatible. We had to manually adjust the diameter of the holes by using a screwdriver to … Continue reading Ramping it up

We presented our progress at Progress Check 1 by providing a live demonstration of how all our prototypes have been failing so far, as well as pitching our new idea that was developed on 17 June. Find our slides at this link: https://docs.google.com/presentation/d/1-rBmlqIA3VzK15CogGcvAaiNTKQonxXfwaZx1kbSh54/edit?usp=sharing  Boots made an appearance at the Progress Check 🙂 . To begin … Continue reading Progress Check 1

We developed a new idea to sort our pipette tips in the correct orientation. It is summarised in the drawing below. Drawing of our idea of a sorting mechanism. (Credits: Yuki) Our idea was to have a rotating wheel in a box full of pipette tips and a ramp, as shown in the drawing on … Continue reading Pivoting time!

We sent the new design of our mould for 3D printing after exporting the 3D model we designed on Autodesk Fusion last week into an .stl file. After collecting our 3D printed mould and shaking it with pipette tips inside the box, we realised that our idea did not work and that the pipette tips … Continue reading Funnel time…

We collected our 3D printed mould from the 3D printer. Upon shaking the box with some pipette tips inside, we realised that the mould was not big enough for the pipette tip to fall out of the box through the cylindrical hole at the bottom (i.e. the 3D printer did not print our design as … Continue reading New new shaking design!

With some reassurance that the idea we had the previous day works (from the success of our cardboard prototype), we created a 3D model of our idea on Autodesk Fusion and converted it into a .stl file for 3D printing. Screenshots from the .stl file of our third prototype. (Credits: KK)
