Edge Lit Acrylic

ANYONE SEEKING TO ADAPT THIS WORKSHOP SHOULD CONSIDER THE FOLLOWING INFORMATION.

WARNING - This workshop makes use of small coin cell/ button batteries. In December 2020, the Australian Government made mandatory safety and information standards for button/coin batteries and consumer goods that contain button/coin batteries (the standards). The standards included an 18 month transition period and became mandatory from 22 June 2022. From 22 June 2022 manufacturers, importers, wholesalers and retailers of button/coin batteries or consumer goods that contain button/coin batteries supplied to Australia, must comply with the applicable Australian mandatory safety and information standards. Supplying or selling non-compliant products to consumers in Australia is illegal. The four mandatory standards are as follows: • Consumer Goods (Products Containing Button/Coin Batteries) Safety Standard • Consumer Goods (Products Containing Button/Coin Batteries) Information Standard • Consumer Goods (Button/Coin Batteries) Safety Standard • Consumer Goods (Button/Coin Batteries) Information Standard

Summary

Edge Lit Acrylic Signs was developed and delivered at 2 Family Maker Club Sessions in July and August 2024. In the First workshop participants learned how to create artwork and then laser etch & cut

Skills Introduced

Bitmap and Vector Image manipulation (PS & AI) - import image, convert to grey scale, invert and isolate negative space

Laser cutting

intro to electronics

intro to soldering

and for extension if you have time basic CAD and 3D printing

Preparation

Before the workshop you will need to ...

Workshop Walk through

Workshop 1

Step 1

Welcome and Tour

Step 2

Laser Demo

Step 3

Artwork Demo

Step 4

Participants decide on an idea

Step 5

Participants prepare artwork

Step 6

Participants prepare and cut artwork on laser.

Workshop 2

Step 2-1

Welcome and Tour

Step 2-2

Intro to Electric Circuits (conduct a scaled down version of Electronics 101 ) with a special focus on:

Current flow - Atoms passing their free electron from Neg to Pos

LEDs - Polarity

resistors - Restricting the flow of current in the circuit.

Step 2-3

Demonstrate building the circuit in Fritzing edge_lit_acrylic.fzz.zip

Start by showing what happens if you dont have the resistors edge_lit_acrylic_no_resistor.fzz.zip

Step 2-4

Look at https://ledcalculator.net/ for their suggestion for 4 LEDs with 4.7V

and then add the resistors in Fritzing

and show the outcome

Step 2-5

Show how the current flows on the positive and negative sides of the circuit

Positive accross the top and negative from the bottom via each of the resistors

Step 2-6

Participant place their components in the circuitboard board.ai

and using a print out of

Hints add your leds and working from the back of the circuit fold positive legs around the next LED. Then add your 2 resistors and then fold your negative led legs to connect these up. Finally connect the positive and negative sides up to the leads on your battery box Test you have you have LED Polarity right with a coin cell battery as you go

Step 2-6

finish up by soldering all your joints together and then trim the loose legs so they don't cause a short.

Step 2-7

Put your circuit and batterybox in the Plinth that steve designed for 3D printing.
