Helloooooooooooooooooo!
Okay, this is stupid. Where am I going to find an ammeter, voltmeter, resistor and light box???
I can't just use my lamp, because the light spreads out. I need a light box with like un-dispersed light.
Wait, can we borrow from the school? Remind me to ask Ms Zhang later.
Anyways, I still need to buy colour filters/transparent paper. Today, my dad bought this electronic photo frame, and it came with a medium sized frame. I'm going to use the frame to stick my colour transparent paper on for the light to shine through.
Here's an updated list of equipments I still need to get, the striked words means that I already got them:
⚨ Voltmeter
⚨ Ammeter
⚨ Resistor
⚨ Light Box
⚨ Colour filters (red, orange, yellow, green, blue, violet)
⚨
