The new black BI2 board is ready. I have a few assembled boards ready for shipping. Have a look at www.tindie.com
3 JST 1mm plugs (battery, motor 2, motor 3), LED, reset button, M+/M- is for motor 1
JST 1mm plug for motor 1, alternative RESET button
ESP8266 Microcontroller with WLAN
MPU9250 (accelerometer, gyroscope)
LiPo battery charging
3 motors can be connected (simple motor driver circuits)
1 WS2812B LED – a colourful LED (16 Mill. colours). They are commonly known as Adafruit Neopixel – a strip or a ring of individual programmable LEDs (when use the WS2812B only two motors can be connected)
design based on the great Adafruit Feather Huzaah ESP8266
vibration motors and LiPo battery can be easily connected with JST 1mm connectors
two reset buttons (the button next to the USB connector can be overmolded)
USB connector for battery charging and code uploading
programmable with the Arduino IDE or NodeMCU
white LED for indicating charging
standard LED (yellow) on GPIO00
round 40mm diameter
There are 3 free GPIO ports. Standard layout are for driving 2 motors (GPIO 12 = M2, GPIO 13 = M3) and 1 LED (GPIO14). Alternatively you can use 3 motors (GPIO12,13,14) but no LED.
Standard: SJ2 not connected, SJ3 connected
Alternative: SJ2 connected, SJ3 not connected
Here is the schematic which is adapted from Adafruit.
They created a website for sharing designs for strap-on dildos. In addition the strap-on dildos is part of a harness. Some parts can be 3d printed but the harness must be made by leather or other material which could be out of scope for most DIY people. The inventors say that their toys are made for ecosexuals which practise sex in nature.
Another project is very impressive as it offers a touch surface for a “insertible toy” eg a penis. This could be used for teledildonics application for capturing and transmitting haptical experience. The construction of the capacitive surface is very impressive. In addition algorithms are introduced for gesture recognition. Gestures? The author explains: “Well, I want to be able to tell what the user is doing with the device (e.g. blowjob, licking, hand job and penetrative buttsex)”.
Another exciting project is a masturbator demonstrator which was molded using 3d printed forms.
