Deoxy i ching3/28/2023 ![]() ![]() I threaded this through an existing hole, and as with Socket on the TellyMate shield is clearly labelled “TV” in the I also attached the RCA video out cable to the TellyMate shield (its.IĮventually ditched the 9V battery for fear of exceeding the 5V maximum 5V out and GND (these are to power the LM386 amplifier circuit).Spinning of the direct drive motor) Ultimately only A3 was used. A3 and A5 (these are to read the voltage that is generated by the.D2, D3, D7 and GND (these are for the rotary encoder).I attached a TellyMate shield to the top of the Arduino and connected long wires to pins I rigged up the LM386 amplifier circuit like this īelow is a schematic of the LM386 amplifier chip circuit in the picture above Steps as I spent much time getting the amplifier chip circuit working) I feel that it is still worthwhile to document these I attached an LM386 amplifier chip to the breadboard, and positioned aĩV battery nearby to power it (Note: The amplifier circuit was laterĪbandoned due to the fact that it was generating large bursts of Pushbutton (although this is not exactly as it appears in the pictureĪbove as I had yet to add the 10k resistors at that point The following diagram is a schematic of the rotary encoder with The cables from the rotary encoder to it, and connected cables from the I attached a mini-breadboard next to the rotary encoder, connected To stop it coming loose from the Raspberry Pi if it were to get tugged I secured the Blackberry Mini-USB lead it with a screw at the hole Raspberry Pi. I looped the cables through the existing holes at theīack. I connected a Blackberry Mini-USB charger and HDMI cable to the Now the inside of the turntable looks like this I threaded a USB cable between the Raspberry Pi and the Arduino. I found a hole left from when I removed the pitch control that was the perfect size for my rotary encoder There were existing screw holes in just the right places to attach the Raspberry Pi and Arduino. In the spaces now made inside the casing, I found nice places to position the Raspberry Pi I then ripped pretty much everything else out of the turntableĬasing, the power supply, the pitch control, the audio cable, etc Once I worked out which connectors they were I soldered wires to themĪnd ran the wires through a pair of very conveniently positioned holes Motor produce a current when the shaft of the motor is manually spun I used a voltmeter to find out which connectors on the direct drive We can say confidently that the least significant threeīits of this total will be a random number. We can using one of the Arduino’s analogue input pins and simply total This will occur regardless ofĭuring each spin of the turntable we sample these voltages as fast as Such a motor is that if you turn the turntable by hand, the magnets will Turntable round when the turntable is working normally. The turntable produce a rotating magnetic field which drags the I removed the direct drive motor which is a synchronous motor. I eventually ditched the Roulette wheel idea, but I didn’t let go of Infra-red transmitters etc on the wheel itself would be quite likely toĭisrupt this balance and cause the ball to have a greater probability Wheels are finely balanced, thus embedding any sort of Arduino, sensors, Rotating would require some sort of wireless technology. Information to a physical location beyond the point on which it is Getting a wheel to spin smoothly and also be able to relay.Have to find a Roulette wheel whose number of pockets is a multiple ofĨ. (in American roulette), to recreate the throwing of three coins I would Roulette wheels have 37 pockets (in French/European roulette) or 38.I really like the idea of hackingĮxisting devices, but there were a couple of problems with the Roulette Placing sensors in the pockets that detect where the ball has landed and I then investigated the possibility of using a Roulette wheel, Open it in presentation mode, I’ve added some explanatory comments) Times and the system then displays your generated and transformedĪlthough the Max patch looked impressive (see Figure 7), this idea was a bit weak. Represent the number of heads you’ve thrown with three coins. Simply have a box where you press either 0, 1, 2 or 3 buttons to Replicate the throwing of three coins as in the traditional techniqueįor casting the I Ching, in a way that feels in tune with the Tao.Īn early (and fairly crude) idea, that I prototyped in Max/MSP was to The I Ching Turntable project originated from an interest in how oneĬould generate random numbers in a computer system using a physicalĮvent, I have never been convinced that computer generated random ![]()
