Project development¶

When i applied for the study place in Fabacademy 2025 i started to think about what to do as a final project, i had few ideas one was a drone, another was a robotic arm that can grab and move things while he organise them. But after i got my work schedule for the semester i realized i was going to do this study with 160% work, that lead to the conclusion that´s itæs maybe better to go for something more simple and be able to finish my project.

Then i was think of the time when i needed to visit the restrome one dark night when i was in Norway and kick a little chair on the way and hurt my little toe.and came up with the idea to make some warning system for small furniter that can be in such hollways, to warn people that they are coming to close and surve as a night light at the same time.

This was simple project that i thougt was possible to do on this time i had with my work without leting it affect my work to much. So i went for it.

This project was simpple so i realy did not have to much problems on the way, i started to think how i wanted to be so i made my first prototype in fusion. This was the the out come

Chair

Well that was only my third time useing fusion so i was pretty happy with the outcome.

Then we came to computercontrole machin week the i decided to cut out the table that i was goin to use in my final project. So i design new table and cut it out in 12mm plywood(should have use thicker and more better wood) and this was the result.

Table

i was really more happier with this version so i used it but i wanted to add something more to get some more live in it so i made little plexiplast plate to put under it beetween the feets.

This is the plexi plate plexi

And then here is the table with the dark plexiplate

with plexi It´s look much better like this

Then it was time for making the electronic to designe the electronig i used Kicad. This is the reasult from kicad

Who has done what before hands?¶

Searching the net and fabacademy site i didint find anything that was exacly the same thing, i found that people have done many things whit table but never turn them direct into nightlight whit warning system. Then i found speaker table by Anubhav Jain.

Quick searce on the nett reveled there is alot of furnitur on the market with inbuilt lights but none i found have sensor to activate the lights.
I think it´s very interestet that there are not more furniture on the market haveing intergrated night light with sensor.
On the internet it´s easy to find lights with sensors it´s all kind of lights and almost all light producer in the world has some kind of light that has sensor, tabel light, celling light and lights to intergrate in other things.

WHat will i designe?¶

i will designe a table that has intergrated night/warning light that let you know if you get to close, it´s speciali thought that it will warn u and make it self visible if it´s dark area.
the system wil work like this if ýou come in the range of 100cn light will turn green when you are in the range of 55cm light will turn yellow and when you are in the range of 45 cm the light gets red.

Designe a table
Design the electronic
Design the the seat for the light
Design the house for the sensor
Desigen the house for the electronic and the poewer bank

what part and system will be made?¶

I will make the table from some 12mm ply wood in the shopbot machine,i will then make the electronic design, mill and solder, i will use xiao ESP32c3 that is factory made and add him to the circut with sockets, the sensor i will by and the powerbank , then i will make the bottom plate for the table in the laser cutter from dark plexi. and print out in PETG the house for electronic, sensor and the ring for the light. light stribe is bought.

What processos will be used?¶

For the wood i will use the shopbot and cutt out the table. For the electronig i will mill out the circut either with the Roland mill or the lunyee mill. For the printing i will print all things in my Bambulab A1 printer FOr the plexi plast i will cut that out in the lazer cutter

What question need to be answeard?¶

The bigest question is what sensor is best to use?
How ti intergrate all pieces to gether?
In my project i got one question from people that i wasint expecting every one asking if what i started with as a chair was a table, so in the end i called it table. But it still can be used as i high chair.
What processor to use?

How will it be evaluated?¶

This project will be evaluated after how its work, that is if it work as intended, and of course also by its look. And how it was intergrated.
In this project i onluy used 5 screws 3 to fasten the bracket for the ligt and 2 for the electronic housing. And after testing then it seams like this is working nicely.

What task have been completed?¶

All task have been completed.

WHat task remain?¶

No task remians.

What has worked? What hasn´t?¶

This was very smoth project, maybe not complicated enough. But however i had few problems with the sensor, when i had program the system and teste the light wasint stable enough it was flickering so i needed to add some thing to the code like let the sytem read the color of the light before change color, and to read avreage distance and use that distans to controle the color.
Designing the 3d printet parts only problem i had was the house for the sensor was to small, so i had to redesing that.

What question need to be resolved?¶

There are no question to be resolved to finish this cycle of making that project ready.
But in the next cycle it´s a question if i shoukd use another type of distance sensor, and adding on/off button and even if it should hafe light sensor to to turn off the circut at day time when its no need for light to save battery.

What will happen when?¶

June 12 2025 i will present this final project.

In the future i will change out the ultrasonic sensor for the another type of sensor.

What have i learnd¶

This few last months has been increadble jurney. i have learn how to create my own electronic circut, i have learnd to designe my own electronic and 3d design. i have learned to use machines that i only dreamd of i ever could use before machins like shopbot, lazer, 3d printers and the mill. In the begining of this course i could not have design any of this with out outside help but to day i am confident that i can do som 3d design on my own(not proffesional tho) and produced the product using the equipment in the Fab lab faciliatory. I have also learnd basics around makeing your own things. It will be so fun to use and widen that knowlegs in the near future.
