Incredible Shruthi-1 hardware synth with its excellent SMR-4 MkII filter board, both of which I built about a month ago and which I love to bits for exploring new sounds. However, as a sound designer I`ve always been interested in pushing the boundaries, so having dusted off my electronic engineering skills, polished my soldering iron and retrieved my component boxes from the shed I`ve spent

many spare hours over the last few weeks seeing what other sounds I could coax from the SMR4-MkII filter board. 1. First of all, I was green with envy when Olivier`s stunning 4-pole mission filter was released, so I cherry-picked my favourite six filter shapes from it and reverse-engineered them for the SMR-4 MKII: LP2, LP4 BP2, BP4, HP2, and Notch 2. Second, I explored the wobble` filter character from the 4-pole mission and implemented it as a variable Filter FM control going from none to serious filth. 3. Finally (and what took most time, energy and listening sessions) I extended the Mission/Polivoks MS-20 distortion` feature so that the SDE has six Filter Flavours that each react dynamically to incoming audio signals: e) HARD adds a similar amount of distortion as GERM, but this time predominantly third harmonic and less second for a harder-edged sound with added sub-octaves. 4. I couldn`t resist adding yet another feature to the Shruthi-1 SDE after hearing the Polivoks in action: Output: Drive offers some subtle to serious overdrive and distortion options, along with a tweak to output level to make the SMR-4 MkII presets all run within -10dBV input sensitivity on your audio interfaces. On my setup some presets previously needed turning down or my interface switching to +4dBu to avoid digital clipping. Now everything runs nicely at -10dBV so you don`t have to watch the meters ;) 5. I`ve been exploring some internal...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
