Ic1a op amp1/1/2023 In this mode, it acts mostly as a hard step function, although there is some “play” around the zero voltage point. Since the amp operates in open loop mode, the high gain will drive the output of the amp to the positive supply if the positive input is above the threshold voltage, and toward the negative supply voltage if it is below. The third pot R4 on the negative input sets the threshold of the neuron. To realize this, the output of summer IC1A is fed into op-amp IC1B, which is configured as a comparator. In order to implement Neuron Property #2, we need the squashing function. Resistor R12 is used to tie the summing point to ground in case of no inputs. The first op-amp IC1A is configured as a non-inverting summing circuit, to sum the voltages from the two inputs.

The three MOSFETs (T1, T2, and T3) are configured as a wired-OR gate to drive the shared beeper. The monostable times of the upper and lower MMVs are dimensioned to generate clearly distinguishable short and long beeps, respectively. Most rotating laser levels have variable speed, so this can also be achieved by adjusting the speed if necessary. with a 2 rpm laser it should be longer than 500 ms) so that the beeper will emit a continuous tone. The monostable time of the middle retriggerable MMV should be longer than the rotation period of the laser (e.g. In this case, the output signal has the opposite polarity, so the BS170 N-channel MOSFET must be replaced by a P-channel type. If desired, the circuit shown inside the dashed outline (one gate of a CD4044 quad RS latch) can be used in place of each of the monostable multivibrators. The rising edges of the opamp output signals trigger three separate monostable multivibrators (type CD4047).
