Introduction: DIY Negatoscope

About: Hey there! I'm a Venezuelan DIY Enthusiast. i hope my projects can be used by any to make their life easier. Have fun always people.

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.

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.
