USB powered charging station for the silicone molded vibrator

charging-station-in-action-with-body-interaction-vibrator-so-much-balls-smallWe made a DIY silicone molded vibrator (see here, here and here) using the Arduino compatible body interaction vibrator development board and a wireless charging module. Now we need a charging station where you can put your vibrator for battery charging.

We need a simple box for the wireless charging sender (transmitter) module and the coil. In addition we need a USB cable which we will cut though and connect to the charging module.

It is important to keep the distance between sender and receiver coil as small as possible. The larger the distance is the less power will be transmitted. Therefore the plate where you put the vibrator must be very thin. There are different modules available.

 

What do you need?

  • A USB cable
  • Wireless charging sender (transmitter) eg. from Seeed Studio, 5V input. The sender (transmitter) will be placed in the charging station. The receiver module will be part of the vibrator. There are different modules available. Look for a 5V input module.seeedwirelesscharging

Instructions:

A. Print out part A and B. Download STL files (zip file)

B. Cut a USB cable. Plug the cable through the hole of form B.

C. Now connect the USB wires with the sender module. Solder the red wire to the (+) pad on the wireless charging sender. Solder the black wire to the (-) pad.

D. Glue the sender board on the bottom of the red form. Put some glue on the cable to fix it. We used hot glue.

charging-board-and-cable-glued

E. Now glue the black form and the sender coil together. We used simple “UHU”-like glue. If the distance between coil and form is too large the charging could be rather slow. So don’t use too much glue.

New fusion 3d printed and silicone molded vibrator

fusion tinkercadThis is the initial design. The round curved form will be in silicone with vibration motor within (vibration motor not shown on sketch). The red part is 3d printed. It is the enclosure for the body interaction vibrator development board and LiPo battery. You can plug-in the Micro USB connector for battery charging. In addition there is an on/off switch e.g. for travelling.

Update for “balls revisted” – silicone molded vibrator

balls-revisited-v3-wit-v4-inlay-blueThe “ball revisited” silicone molded vibrator uses a wireless charging module. Unfortunately there are different version available. The version with some textile like cable jackets have a different inner radius of the receiver coil.new-inlay-from-topWe have changed the mounting on top of the picture as this type of the receiver coil needs a little more space. In addition the encasement is a bit larger. new-inlay-seen-from-side-BThere is enough space for the body intercation board (top), wireless charging board (right) and the LiPo battery (below).new-inlay-seen-from-side-BFinally the wire of the vibration motor is glued in the middle of the encasement.new-inlay-from-belowPlease follow the “old” instruction – nothing has changed. When printing out the 3d parts use the new version 4 of the inlay. All 3d printing STL files at Thingiverse

 

Silicone overmolded vibrator – balls revisited

molded-quermolded-with-ueberh-querBuilding your own silicone molded vibrator becomes now easier. We already have presented 3d printed forms for building your personal vibrator (massage wand, wireless charged vibrator). The vibrator uses the body interaction vibrator development board. The body interaction board has a Arduino compatible microcontroller, vibration strength control by motion, a vibration motor and a rechargeable battery.

 

balls_revisited_3_inlay_part_bWhat is new? The electronics including battery are in the base of the vibrator. We developed a 3d printed enclosure for the electronics. This has several benefits: The assembling of the electronics and the molding itself is easier as everything is fixed within the enclosure. And it is more safe as the enclosure shields the electronics from the environment (and vice versa). In addition we used a different charging module from Seeed Studio. The input voltage is only 5V. Now you can connect the charging module with a USB connector and don’t need another power supply. (Look here for an explanation of wireless charging sender and receiver.)

overmolded-vibration-motor

Another improvement is the placing of the vibration motor. The vibration motor can now be placed in the center of the vibrator and it different heights. Just were you need the power.

balls_revisited_3_inlay_part_aFinally the mounting is improved. The mounting holds the enclosure when it is inserted into the form.

balls_revisited_3_finalThe mounting (together with the enclosure with the electronics) is inserted into the form. The form consists of two parts which must be fastened together by tinker wire. It is a variation of the ball theme.

We present a step by step procedure for tinkering the vibrator. You need:

  • 3d printed form (molding form, 2 parts)
  • 3d printed enclosure
  • 3d printed mounting
  • body interaction vibrator development board
  • silicone with a high shore A value (eg. shore A 45 which is quiet hard but still flexible), approx. 100 ml
  • wireless charging module eg. from Seeed studio
  • soldering station, (hot) glue

Step by step procedure:

A. Print out all forms. You can download the forms from Thingiverse.

wireless-charging-sender-and-receiver-line-pf

B. Connect the wireless charging module to the body interaction vibrator development board.

B.1 You have to solder a wire connecting (-) on the wireless charging module and GND on the body interaction board.

B.2 Now comes the tricky part. You have to connect (+) from the charging module with the body interaction board. Solder a wire at (+) of the charging module. But where do you solder the wire on the body interaction board? Unfortunately the wireless charging option was not taken into consideration during the development of the board. So there is no appropriate connection on the board.

circuitThe best solution is to unsolder the USB connector and connect to + of the USB connection. The easiest way to unsolder the surface mounted USB connector is done with a hot air soldering station.  Alternatively you can solder the wire directly to the MAX1555 module – this solution is presented here. In any case: Be careful not to break the tiny pads connecting pcb and USB connector.

B.3 Connect the sender module with a 5V power supply. You can use a USB cable, dismantle the cable and connect the black and red wires.

inlay-with-coil

C. Place the receiver charging coil on top of the enclosure. The diameter of the top side is a bit larger than the diameter of the bottom side. Use some glue to fix the coil. Don’t fix the mounting now. It is easier to do it later (step E).

enclosure

D. Put the electronics into the enclosure: Begin with the body interaction board. The RFM12b is quite large so place it at an outer position. Then insert carefully the LiPo battery. Don’t force it! The plugs for the battery and the motor could break. If you have done so insert the tiny wireless charging receiver board. At the end fix the wires of the vibration motor in the middle of the enclosure.

E. Connect the mounting with the enclosure. There are 2 holes provided where the mounting fits into the enclosure. Use some glue to stick together both parts. (see picture above step C).

 

form-unfilled-with-inlay

F. Put together both parts of the molding form. Use tinkering wire to attach both parts tight together. Then insert the enclosure into the form. Check the wireless charging function. The yellow LED must be on when you place the charging coil over the receiver coil.

molded-form

G. Now poor silicone into the molding. We use Shore A 45 silicone which is rather hard. The silicone has to dry for some hours or days. Read the instructions of your silicone provider.

H. When the silicone is hard, you can remove the tinkering wire. Then carefully remove the form.

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.):
http://www.sculpteo.com/de/embed/gallery/?click=order&designer=south

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.
