This is a fairly simple project and is perfect for a synth-diy newbie or a young person interested in synth-diy or making noise boxes. It is slightly more challenging than the Alien Screamer or Weird Sound Generator and would make a great second project unless you already have electronic project skills in which case it will be a piece of cake. This project results in a little LO-FI noise maker you'll find yourself playing with again and again. You will need to know how to: Read a schematic, Relate schematic diagrams to physical components, Solder, Populate a PC board, Wire the unit's front panel components together and to the PC board., Make a simple case or build the board into something unusual.
- Easy to build
- Wide Range VCO
- White Noise Generator
- Cool low Pass Filter
- Simple But Effective VCA
- AR Generator with Repeat or Manual Pushbutton
- LFO with Square, Integrated Square and Differentiated Square waves
- Nicely Normalized Switching Scheme
- PCB Has Pads for Interface to Other DIY Projects
- Built in One Watt Audio Amplifier and Speaker.
- Uses one 9V Battery (portable)
- Low Current Design Extends Battery Life
- Makes a plethora of plethoras of cool and interesting sounds
This kit of parts includes all electronics components, pots, knobs, switches, 1/4" jack sockets, even includes an eleven colour pack of wiring which contains 22m of equipment wire.
We only source quality components and we even include the more expensive turned pin IC sockets as we feel the product justifies the extra cost both for reliability and serviceability. Our 1/4" jack sockets are by Switchcraft, yes you can save money by buying cheaper sockets but we decided against that for our kits. Don't like our choice of knobs, pot or whatever, no problem as we also supply all parts individually so mix and match to suit your own preferences.
Each kit contains the following but excludes the optional PCB or a front panel
