# Week 5 Update

What was accomplished: 

1. Finished designing the peristatic pump, and got the 27:1 gear motor attached to the mechanism
2. Researched syringe pump method as an alternative option in case the peristatic pump wouldn't work. Designed several diagrams, but before reaching CAD phase, found a lot of critical drawbacks that convinced me to use the peristatic pump instead(including linear actuators that require built in encoders)
3. Start working on PPT for the presentation on tuesday

Roadblocks:

1. 3d printed parts for the pump(may be accurate, but should have initially been designed to account for clearance holes for drilling through)
2. Finding the right material for syringe pump(a glass syringe would be optimal to handle all the liquids required, but the larger models do not have built in syringe needles, so a glass syringe + recyclable needle with luer locks was thought out)

TO DOs:

1. Finalize PPT for tuesday
2. Help Advaith move the pump mechanisms into the overall assembly, as well as implementing other components(Im not sure how the spin coater is going to look like)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.hackerfab.org/home/working-docs/cmu-updates/matthew-chois-updates/week-5-update.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
