What you need
Step by step
- 1
Step 1
Clear a flat workspace and lay out all your materials where you can reach them.
- 2
Step 2
Place your phone face down on the cardboard and draw an outline slightly bigger than the phone with a marker.
- 3
Step 3
Cut out the cardboard rectangle along the outline using scissors.
- 4
Step 4
Fold up two small tabs at the short ends of the rectangle to make a front and back stop for the phone.
- 5
Step 5
Stretch two rubber bands across the top of the cardboard where the phone will sit and tape their ends to the underside so they act like straps.
- 6
Step 6
Tape a drinking straw to the center of the cardboard underside so it sticks out as a handle.
- 7
Step 7
Poke a hole in the side of the paper cup big enough for the straw to slide through.
- 8
Step 8
Slide the cup onto the straw so the cup hangs below the cardboard rig as a counterweight.
- 9
Step 9
Drop 4 to 8 small coins or washers into the cup to add weight for stabilization.
- 10
Step 10
Slide your phone into the cardboard cradle and pull the rubber band straps over the edges to hold it securely.
- 11
Step 11
Cut a small square of transparent coloured plastic to make a gel for the camera lens.
- 12
Step 12
Attach the coloured plastic over the phone camera using the clothespin or a binder clip so the colour is in front of the lens.
- 13
Step 13
Hold the straw handle and move slowly to check how steady the rig is while filming.
- 14
Step 14
Add or remove coins from the cup to fine tune the balance until the camera moves smoothly.
- 15
Step 15
Take a short video with your rig and share your finished creation on DIY.org.
Fun facts
How do you hack your film gear and build simple DIY rigs?
Start by planning a simple shot and sketching what gear you need. Build a smartphone rig by attaching a phone to a lightweight frame (cardboard, plastic container, or small mounting plate) with rubber bands or a clamp. Make a handheld stabilizer from a short PVC or wooden dowel with a wrist strap and optional counterweight. Create colored gels by cutting cellophane or transparent folders and attaching with clips. Test, adjust balance, and practice steady moves.
What materials do I need to build a smartphone rig, stabilizer, and colored gels?
You'll need a smartphone or small camera, rubber bands or phone clamp, cardboard or a small plastic mounting plate, tape, scissors, clothespins or binder clips, PVC pipe or wooden dowel for a handle, small weights (washers or coins) for counterweight, stretchy wrist strap or lanyard, colored cellophane or transparent folder sheets for gels, foam or felt strips for padding, and basic tools (ruler, marker, hot glue or strong tape).
What ages is this DIY film gear activity suitable for?
This activity suits children about 8 years and up with adult supervision; ages 8–11 enjoy building parts with help, while 12+ can design, balance, and film more independently. Young kids should focus on safe, simple builds and practice handling the phone; older teens can try more complex stabilizers, lighting gels, and editing. Adjust tasks, tools, and supervision to each child's fine motor skills and attention span.
What safety tips should parents follow when kids hack film gear?
Prioritize safety: supervise cutting and hot-glue use, keep small parts away from very young children, and secure the phone with straps or a clamp to avoid drops. Test weight balance before filming to prevent wrist strain; avoid overloading handles. For gels, avoid covering phone vents or overheating the device under strong lights. Teach safe tool handling, tidy cables, and set up on stable surfaces to prevent trips or falls.
Watch & Learn
Need help?
What can we use instead of hard-to-find items like rubber bands, binder clips, or transparent coloured plastic?
Use elastic hair ties or Velcro strips instead of the rubber bands (step: 'Stretch two rubber bands...'), a clothespin or strong tape in place of a binder clip (step: 'Attach the coloured plastic...'), and cut coloured cellophane from a candy wrapper or a clear plastic folder for the transparent coloured plastic gel (step: 'Cut a small square of transparent coloured plastic').
Why does my phone wobble when I move the straw handle and how do I fix it?
If the rig wobbles when you 'Hold the straw handle and move slowly...', tighten or replace the rubber-band straps and add or remove coins from the cup to rebalance the counterweight (steps: 'pull the rubber band straps...' and 'Add or remove coins...'), and reinforce the straw by taping a second straw alongside it (step: 'Tape a drinking straw...').
How can I adapt this activity for different age groups?
For younger kids, have an adult pre-cut the cardboard and use a toy phone or thicker cardboard with Velcro straps for safety (steps: 'Cut out the cardboard rectangle...' and 'Stretch two rubber bands...'), while older kids can design adjustable straps, experiment with different coin weights, or add a tripod mount to improve footage quality.
How can we enhance or personalize the rig to make more creative videos?
Decorate or paint the cardboard, create multiple coloured gels to clip over the camera with the clothespin (steps: 'Cut a small square of transparent coloured plastic' and 'Attach the coloured plastic...'), add a small LED light to the cardboard edge for lighting, or install a 1/4"-20 tripod screw to the underside to connect to standard tripods for steadier shots.
