This is my first post and by the time im going to show you a 2 days project: A Homemade Negatoscope or "Box of Light". This tool its used by healthcare to detail a radiography.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Step 1: Materials and Design
For this Simple project I use:
- Wooden slats 0,5cm of thickness
- 2 x AWG18 Wire (2 meters)
- 1 x White Light Bulb
- Acrylic Sheet
- Terminal Block
- On/Off Switch
- Fuse Holder and a 5 Amp Fuse to Protect the Bulb.
- Industrial Glue
- White Paint (Spray recommended)
- Tools like Dremmel and saw
It haves a simple design with a small inclination at the front panel so can be used in two diferent ways to get comfortable: working stand-up or sitted.
Step 2: Step 2: How It Looks Finished
Someting important to know is that this negatoscope works with a voltaje 120VAC so its circuit is easy to make. All the components have to be connected in series. A Terminal block can help you making the connections you have to made a piece of cake just hold your DVM next to you and be carefull with any short circuit.
Its recommended to paint with a light/reflecting color Inside the box to increase the power of the lamp, i use white paint but silver can works too.
