Final project

one of my idea for final project came to me one night when i was walking to the restroom in the dark hallway and i walked direct into a small chair that had been left direct in the walk path. and i hurt my litle toe. Then i thougth i maybe able to make chair(or some kind of furniture) that will activate some light and/or sound alarm if you approche it to musch in the dark. I could see that people want that kind of furnitures in there houses not only to warn them but its usefull as night light at same time.

I did some little poor sketch in this first week. first sketch

i am curently working on geting some more thougts on how to develope that project an come up with another possible final project. i will add later info about that one.

Week 2

This week i made 3d model of an chair that i am thinking to make. I used Fusion and followed instruction from copilot. and render that in Blender.

here are transcript of instruction i followed from copilot:

Creating a 3D model of a small chair without a back in Fusion 360 is a great way to practice your CAD skills. Here’s a step-by-step guide to help you get started:
Step-by-Step Guide to Modeling a Small Chair Without a Back in Fusion 360
1.  Open Fusion 360:
o   Start a new design by clicking on File > New Design.
2.  Create the Seat:
o   Sketch the Seat: Click on Create Sketch and select the top plane. Use the Rectangle tool to draw a rectangle that represents the seat of the chair. For example, you might use dimensions of 40 cm by 40 cm.
o   Extrude the Seat: Finish the sketch and use the Extrude tool to give the seat thickness. For instance, extrude it to a height of 2 cm.
3.  Create the Legs:
o   Sketch the Legs: Create a new sketch on the bottom face of the seat. Draw small rectangles at each corner of the seat to represent the legs. Each leg might be 4 cm by 4 cm.
o   Extrude the Legs: Finish the sketch and use the Extrude tool to extend the legs downward. For example, extrude them to a height of 40 cm.
4.  Refine the Model:
o   Add Fillets: Use the Fillet tool to round the edges of the seat and legs for a smoother appearance. Select the edges you want to fillet and specify the radius.
o   Adjust Dimensions: Use the Modify tools to tweak the dimensions and positions of the legs if necessary.

I am well on the way to have this project ready. there are som few fix i need to do

  1. Laser cut base plare under the chair(plate that comes beetween the legs of the chair about 20-30cm obove the floor)
  2. print somthing for the electronic that will come on the plate in no one or under the chair.
  3. make final electronic or place the one i have from output week, that could be used but with out the 230V relay.
  4. add som led on the foot of the chair
  5. test and make some final adjustment.
  6. Finished documentasion
Task date finished

In the finalproject i will use the chair i cut out in week 07 as the furniture i call it a chair but many people call it a table causee it is little bit high to be a chair but that i did on purpose i wanted it to be something beetween a normal chair and bar chair. chair This picture shows the final look on the chair it self, but i want to add a lazer cut plesi plate beetween the legs about 30cm from the floor. then i have to #d pront somtheing for the electronic, put at least one ledstribe on the inside of the leg. Thats all i have to do i think, if time will allow i will add lights to all the feets and sensor to at least to direction.

Here is the lazer cut plexiplast that i made for the chair, orginali i was thinking this as a CHair but this works better as a table so from now on i call it a table.

And picture of the Table with that plexi installed.

System Intergration

I did make a workflow system intergration plan that look like this.

system  intergration

This workflow show what is suppose to connect to geather and what parts are going to depends on each other for the project.
Then after i did this i was not really happy with it so i opend chat gpt and ask him to makeme system intergration slide.

Here is the text i gave chatgpt

make me system intergration slide of a table that will interact to movement using ultrasonic sensor and xiao esp32c3 if you walk to the table then it will turn  on green light then if closer it will get yellow and then red. have to make the whole system

and this was the outcome
