ThingaMa-Buzz. There are two low frequency oscillators per light with a smoothness control (slew rate) per channel. one of the oscilators can be assigned to either channel.
The Network Shield provides a 10/100 Mbps Ethernet PHY to allow connection to an Ethernet network. It provides the connectors and load switch to support use of the USB 2.0 OTG controller to implement USB device, USB host or OTG operation. It also provides two CAN transceivers and connectors to allow connection to two independent CAN networks. Connectors are provided to allow connection to two of the I2C busses supported by the Max32.
In addition to the communications features, the Network Shield also adds a 256Kbit I2C EEPROM for non-volatile data storage and a 32.768Khz oscillator to allow use of the Real Time Clock/Calendar (RTCC) peripheral in the PIC32 microcontroller.

The 10 MHz reference oscillator and the 2256 MHz phase locked oscillator are on the left. The 2.4 GHz filters are in the centre foreground and the receive preamp and tx driver amplifiers are in the brass U shaped channels on the right.

Lots of goodies.

This is the schematic of an analog synthesizer board. The Voltage Control Oscillator, Voltage Controlled Frequencies, Slew Limiter, Inverter, Low Frequency Oscillator Voltage Controlled Amplitude, and ADSR (attack decay sustain release) are all there. (thats the white boxes).
The beauty of analog synths are their adjustability and purity. You have complete control over the waveform from input to output, rather than cheating by selecting some god-forsaken preset that "sounds" like a violin, or a preset that mimics some other noise. And really, the noises you hear are 'pure' (not digitally sampled). The battle between digital and analog has leaned in favor of digital, sadly. To give you a better idea of what digital sampling does to a waveform, look here; cnx.org/content/m15655/latest/graphics1.png
I took some liberties in not labeling the units for aesthetic purposes. The sounds generated from this board are distant and strange, and I felt a background like this best reflected the nature of the sounds.

Three 6V6s, one oscillator, one P.A. and one modulator. As you can see, this is one very compact rig.
Fitting the PCBs to the amplifier backplane. The 'common' PCBs (pre-emphasis, oscillator and motor speed control) and one channel are fitted. In front are the modules for the second channel.

This is a prototype for a backpack with flapping wings. A simple oscillator circuit and amplifier powers electromagnetic coils that oscillate an armature bar. The force is transferred to flap the wings. The design is loosely based off the robotic honeybee developed at Harvard University.

This lilliputian noise machine by Modal Electronics is hiding some serious power.
4 voices, 8 oscillators per voice, duo and polyphonic modes, unison/spread for choral effects, a real-time sequencer, arpeggiator, midi clock syncing, a 16-key touch keyboard… Where did they fit it...

This was supposed to be a funky voice oscillator thing... they turned it into a pendulum with a laser and a string ... something about humans' obsession with light or something.
A few documentation shots of the multi oscillator, light reactive synths I've been building for various performances as part of Sanctuary 2015. They use the amazingly hardy perennial favourite IC, the 40106 CMSOS Schmitt trigger.
There are also a couple of not synths, but percussive instruments made from jars, piezo electric contact mics and m3 nuts and a silver dollar respectively,
