The Voldemort Disarmer

by alexander_Bits

Published on November 4, 2016

I've made a little contraption that will disarm Voldemort.  I took a box and attached a servo motor to the side  Then I attached a mechanical arm to it via screws.  I made a circuit that goes like this: battery+cable then BLE Bit then servo then wire and at the end of the wire I put a bargraph.

I attached the bargraph to the mechanical arm to add that wand like beam.  Then I drew Harry's wand and attached it to the mechanical arm.  The servo will open the box when I shake my phone, then Harry's wand will start swinging and battling Voldemort.

Ask any questions about the build in the comments.

Duration: 20+ minutes

How To Make It

STEP 1 : Circuit

41d3ca68 1238 41ff 933d bac035690390

Assemble the circuit like this: battery+cable/power bit then BLE then servo motor then wire and finally bargraph. Then put the the power bit, BLE, servo, and wire onto the mounting board as shown in the picture. Note: leave the bargraph hanging as shown in the picture.

STEP 2 : Servo Add Ons

Screw the servo mount onto the servo motor and add the adhesive shoes to the bottom of the servo mount.

STEP 3 : Hub and Mechanical Arm.

87be00fb 0da9 4b58 9ac0 b6a1f346cf38

Add the servo hub onto the servo motor and screw the mechanical arm onto the servo hub as shown.

STEP 4 : Bargraph Attachment

Now grab some tape and tape the bargraph to the end of the mechanical arm/wand to give the illusion that the bargraph is the tip of the wand disarming Voldemort.

STEP 5 : Into the Box

B31b5455 2364 4f5b b299 1cfcbfee3219

Now put the entire circuit into a 20 cm long, 15 cm wide, 7 cm high box as shown in the picture. Note: Take 1 glue dot and attach the battery as shown in the second picture.

STEP 6 : Sticky Shoes

2beeb448 5b10 497e 9642 d0c75c9b6b4b

When you put the circuit in the box it should look like this: When you attach the sticky shoes don't forget to make sure that the arm can turn a full 180 degree turn before attaching.

STEP 7 : Tape Sides

C5242442 84bb 4a12 9f92 cb5248c0afce

Now take the sides of the box and tape them to the side to not disturb the servo. Note: only do this step if your box looks like this.

STEP 8 : Photo Add Ons

88ecb614 5f23 492d bbe6 2e563bb787cc

Note: This step is optional but it will make your Voldemort disarmer look much cooler. For this step you can get a few printouts to make it look cool here are a few I put there.

STEP 9 : Box Decoration

39774933 f5eb 4621 97f4 c3d0ca7f982a

Note: Now this step again optional but it will definitely make it look better! You can make the mediocre box look like a chest by drawing some details on the box.

STEP 10 : Wand Attachment

1ade22f3 2bec 43a6 b295 97b0d03cf95b

You can draw a flat wand from a piece of paper and tape it onto the mechanical arm.

STEP 11 : Flex Add On

Fd466ced 630b 45f9 af4f f0862d62119b

To make sure the box opens properly I would tape some thing flexible to the back of the box.(I had a little propeller that was flexible so I used it.)

STEP 12 : Bonus 1!

F756b0ab c05d 4dc6 99b8 2674ee778189

D419deee cce1 4699 a8f1 13ceaf0197d9

So this is your existing circuit take it apart as shown in the second picture and add a spit.

STEP 13 : Bonus 2!

C3295dc6 0a91 45c7 ab01 5e76915ce370

Now grab another BLE and a buzzer and make the circuit as shown in the picture. Finally attach all of that to the mounting board.

STEP 14 : You're done YAH!!!

You are done and if it doesn't work properly tell me in the comments below.
