Vibrating 3d Printed Necklace

necklace-frontThere are a lot of sensible areas of the body which are also erogenous zones (see Wikipedia). The neck is one of them. Stimulation can be achieved eg. by licking and kissing. The stimulation can be quite strong. So why not try to stimulate your neck with vibration? We think it works.

Think of an artistic designed necklace or collar with a vibration function. The vibration will be turned on when you move and gets more intense when you shake our head eg. while dancing. Or the vibration function will be turned on remotely by your friend.

necklace tinkercadBody interaction has made a 3d design for a vibrating necklace. It can be secured by a solid clip closure at the back of the neck. At this place the vibration motor is positioned which gives an intense vibration especially at the back of the neck but also at the whole neck.

Wireless battery charging of the body interaction vibrator development board

bisiliconeformfilledreadybigsiliconereadyvogel2One major Problem oft DIY electronic sex toys (or massage wands) are the need to charge the batteries. Usually the batteries are charged via the USB connector. This means that there is a physical connection between the sex toy and the USB connector, making it impossible to mold the whole sex toy with eg. silicone.

 

 

seeedwirelesscharging

The solution is to use a wireless charging module (eg. this module from Seeedstudio). It comes in two parts: The sender (IN) and the receiver (OUT). Both are connected with a coil. If you place the two coils close together, the sender coils induces power in the receiver coil. Though you can share the batteries wireless. The receiver could be molded, separating the electronics, batteries, connectors etc. from the environment. The result is a form with a smooth surface enabling secure usage as a sex toy.

 

 

 

bigsiliconeready crossmeovedWe have made an easy DIY solution based on the body interaction vibrator development board, wireless charging module and a 3d printed silicone molding form.

 

 

 

 

 

 

 

 

 

big wireless part a

Part A: The molding form consists of two parts.

bigwirelessform

3d print form A

Step 1: The form comes in 2 parts. Print both parts of the form. The STL file is called part A. After printing polish the inner part of the form as well as the surface between the two sides.

 

 

 

 

 

 

big wireless part bStep 2: Now print out part B. It is used to fasten the board, battery, receiver coil and receiver board.

 

 

 

 

 

 

verkabelung seeedwirelssechargingStep 3: Connect the + pad of the wireless charging receiver board with the pin marked + of the vibrator development board (that’s pin 1 of the MAX1555 battery charging IC). Connect – of the receiver with the GND pad of the vibrator development board. You need two short wires and have to solder them at the two boards.

 

 

 

 

wiresStep 4: Now wind up the wires connecting the board with the battery and the vibration motor. (The connection to the receiver board is not shown on the image.)

 

 

 

 

 

 

 

battery and board installedbattery and board installed 2Step 5: Now attach the coil on the shorter “cross” of part B with some glue. There must be space between the coil and the outer longer cross. Then attach the board, battery and vibration motor as shown in the pictures. you can use some glue to fix these parts. Be sure to set the switch to the ON position.

 

 

 

 

 

The receiver board can be placed within the coil. It’s the small long board in the middle.

Double check: There must be space between Part A and part B. And there must be space between the coil and the upper edge of form A as the coil must be molded by the silicone.

bigsiliconeready removedStep 9: After the silicone gets hard, remove the tinkering wires and softly remove the form A. Remove overhanging part.

 

 

 

 

 

 

bigsiliconeready crossmeovedStep 10: Now you can remove the outer cross of part B.

 

 

 

 

 

 

 

 

 

 

bigsiliconereadyvogel1That’s it. It takes about half an hour (without printing). Before using check carefully that the silicone is solid. Even if you skew the silicone form you should not be able to feel the edges of the vibrator development board. Otherwise there is the danger to get hurt. Use it as a massage toy on your own risk. For charging the batteries place the molded coil over the sender coil. The yellow charging LED should go on.

The next development step is a battery charging station!

Print your vibrator case, visit our galleries and read the quick start guide

The case for the body interaction vibrator development board are printed with a 3d printer. There are two possibilities.

(1) You can use a printing service like Shapeway or Sculpteo. Sculpteo has the advantage that they offer food safe material. This means there are no risk if you apply the case to your skin or even insert the case. Follow this Link to the Public Sculpteo Library. The library offers 3d views, material, color, finishing configuration and price calculation (there are no surcharges for the designer.):

sculpteo library(2) You can print the design on your own 3d printer at home. If you don’t have one you could go to your next Fablab or Hackerspace and ask if you could us the printer. You need a STL file which can be downloaded from http://www.thingiverse.com/south/designs

xyz printerAfter printing the case you can assemble the body interaction vibrator development board. In the blog you will find several videos which explain the assembling. For a quick reference please download our guide: quickstartguide-bodyinteraction1

How-to assemble the vibrator ring case

ringredbottom small ring red side small

We have ordered a food safe version of the vibrator ring case from a 3d printing service provider. The case consist of the main body and a kind of cap to close the case.

The design could be improved to have more space for the battery and a more stable cap. The ring diameter is too small for most males, but you can combine the vibrator ring and the “organic” vibrator for her. The combination of these two vibrators gives you a vibration in two dimensions. (The vibration of  a vibration motor is only strong in one direction – you can think of either the x-, y- or z-axis of a coordination system. If you combine two motors you have vibration along two axes of the coordination system, take three you have vibration along all axes).

The video shows how-to assemble your own vibrator ring.

New vibrator design for the vibrator development board & 3d cases

Chain of Ball 2

Chain of Ball Vibrator design with cap

The new design catches the “chain of balls” design theme used in some sex toys. It was constructed in Tinkercad and it is really simple to do it on your own. This how-to video explains the construction in detail.

 

 

 

many balls body interaction vibrator development board

The design is composed from several spheres

Try it on your own in Tinkercad. Just grab a sphere, make a copy, resize the copy, make a copy again and repeat this until you have a chain of spheres. Now select all sphere and use the “align” tool. That’s it.

The tricky part is the screw cap. This is needed to enclose the body interaction vibrator development board.

Improved vibrator ring

Ring2_6There is new version of the vibrator ring. The height is smaller than in the original version. As there must be enough space for the vibrator development board, the LiPo battery and the vibration motor the case is larger in height. Board and LiPo are now beside one another. The new case is printed with the daVinci 1.0  3d printer with yellow ABS.
