Following up on our previous post where we discovered a big temperature differential between our peltiers during testing, we installed bolts and nuts to the clamp to secure each individual peltier/cooling block to enhance contact. We also began with 0.9 pwm from the beginning so that we could achieve ice faster. Here’s the results from […]
With our clamp and backing finally working, we are at the final stage of testing to see if all our components work together. We know that its possible to freeze clear ice, and its also possible for us to freeze such large ice with the peltiers separately but now we will be testing to see […]
Following up on our previous post, we’ve finished designing our final ice mold clamp and backing with advice from Tony!! Here’s Shuchi with her creation: And here’s a closer look at our ice mold and backing: While we were designing, we realised we needed a method to apply pressure to the peltiers such that they […]
As with every MNT project, 3D Modelling is an essential skill everyone learns and uses – partly to print cheap alternatives that have specific dimensions for what we want and partly cause its cool 😛 Now that we are fully in the construction stage, there’s surprisingly a lot of small miscellaneous parts we need to […]
After working on the software and planning out the designs and materials for our prototype, we finally got around to MAKING it!! Firstly, we assembled the profiles and gussets to create a supporting box to support our main styrofoam machine. We then realised we actually have no space to insert our radiators and water cooling […]
With school in full swing, we’ve been trying to go to lab twice a week with full attendance of all members. To speed up the work, we’ve fully split up the hardware and software components, with Jerry and Dan Hong working on the following. These are the various updates and changes we’ve been working on […]
Already the end of August :ooo we’ve been busily working on both the software involving codesys and RPI (Jerry and Dan Hong) and the hardware involving designing and sourcing the materials (Clarice and Shuchi). Its been about a week since we’ve received our ice mold and contrary to our initial joy with it, we’ve realised […]
After we switched from Arduino to RPI and Codesys, we realised we had a steep learning curve ahead of us as we had to learn how to utilise codesys with RPI to control specific parameters (water flow rate, temperature of ice mold). Firstly, we tried out basic codes such as making the LED blink continuously […]
After a month of deliberation….. we finally got our ice mold!! *insert pic* We initially faced so many problems sourcing our ice mold, namely that a custom stainless steel ice mold requires welding services which are pricey (a few hundred dollars), other materials such as copper oxidising over time and aluminium having much lower […]
While hardware and designing stuff was being settled, we had to decide on our controller – and oh boy was this a nightmare. One of the days we started to experiment on Arduino Mega setup for 3D Printing that was available in the MnT lab. It was a long day at lab trying to code […]
