SynthBend - The Electronic Peasant

SynthBend - The Electronic Peasant

Some of you may be aware of my Electronics Engineering community. A DIY question was asked by a young person ...

"I wish to build a modular style analogue synthesizer . I was wondering if anyone had any relevant circuit diagrams for oscillators, filters or amps etc .....Im really interested in building good circuits but in my own design ".

This made me add some of the Analog Synth Enthusiast Sites in this blog. I also realized that this is a good starting point for young minds to learn analog design. If a student or hobby learner is enthusiastic about some idea, he gets the drive to learn the basics on his own.

When a person who is learning, or even a professional, is passionate about what he is doing; he achieves what is called as Resonance in that filed of activity. This is when Innovations Sparks, this is when an Invention Manifests. This is the beginning of R&D.

Getting back to The Peasant in his own words about this device he created ...

"A classic control-voltage type keyboard and an Appendage ribbon controller would be the heart of the project, with many added features. A large quantity and variety of manual CV modulation controls, such as joysticks, potentiometers, and pressure sensors would also be included."

Gainclone or chipamp is a type of audio amplifier made by do-it-yourselfers, or individuals interested in DIY audio. It is a design based on high-power integrated circuits, particularly the National Semiconductor Overture series.

GainClone Chipamp Audio Amplifier

The Gainclone is probably the most commonly built and well-known amplifier project amongst hobbyists. It is simple to build and involves only a few readily accessible, inexpensive parts. As an amplifier it is highly regarded by many in the DIY community.

GainClone Amplifier Rod Elliott (ESP)

"The amp is based on the Project 19 PCB, so uses a pair of LM3876 (or LM3886) power opamps, run from a ±35V supply. ...........The power supply is conventional in almost all respects. I used a 160VA transformer, a 400V 35A bridge rectifier, and a total of 20,000uF per supply rail - 4 x 10,000uF caps in all."

GainClone Chipamp Audio Amplifier

"The Gainclone amplifier has proved very popular with hobbyists since construction is straightforward and the resulting amplifier has an impressive performance specification.

A Gainclone for the PC Age

Most designs discussed online are aimed at audiophile applications. Here is a design for connection the a PC. It powers up and down with the PC and audio input can optionally be taken over USB."

Gainclone Monoblocks

"But it was the Gaincard that caught the imagination of audio diy-ers around the world and before long, copies of the Gaincard were appearing on internet sites and discussion forums. The Gainclone was born!"

incise.org: gainclone

"I had previously planned to build a small stereo amp using the amp6 kit from 41hz.com. After deciding I wanted a bit more power, I did some research and am now going to build a so-called gainclone amp based on the LM3886 chip."

"First, check out this 3-channel buffer amp Darcy made! It uses the chipamp.com LM3886 amp boards! Feel free to send pictures of your amp and we’ll show them off for you."

8051 Macro Assembler ASEM-51

In 1979 Intel has introduced the 8051 as the first member of the MCS-51 family of microcontrollers. Today hundreds of cheap 8051 derivatives are available from dozens of manufacturers. This makes the MCS-51 architecture so interesting for professionals and hobbyists.

8051 Macro Assembler ASEM-51

Intel had also defined an 8051 assembly language with bells and whistles for all the subtle peculiarities of the MCS-51 core, and offered a well-designed 8051 assembler, the legendary ASM51. Unfortunately, Intel obsoleted all its MCS-51 development tools in December 1993. The original (and IMHO best) 8051 assembler was gone and no longer available! ....... - W.W. Heinz,

ASEM-51 is a two-pass macro assembler for the Intel MCS-51 family of microcontrollers. It is running on the PC under MS-DOS, Windows and Linux. The ASEM-51 assembly language is a rich subset of the Intel standard that guarantees maximum compatibility with existing 8051 assembler sources.

"In the letter, they told me that they had used my ASEM-51 V1.2 to develop the motor-control software for a little Mars car prototype..."

8051 Macro Assembler ASEM-51 in Mars

They had validated several 8051 assemblers, and found ASEM-51 to be the most reliable and best documented one.

Electronic Projects of Mast

Projects with Basic 52
  • Using DS1621 temperature sensor chip with BASIC-52 (Temperature logger)
  • Using ADS1286 12-bit ADC with BASIC-52 
  • Cheap R2R DAC for BASIC-52 with performance analysis 
  • Using RF modules for wireless communication with BASIC-52 
  • Sinewave generator with AD9835 DDS, driven by BASIC-52
Electronic Mmicrocontroller Projects of Mast

My first 8052 BASIC Project

"So, first of all, you need a 80C52 or compatible microcontroller. There are several producers, I used Atmel's AT89C52 which is FLASH based, so it can be reprogrammed (as opposed to 80C52 which is OTP part). Any 89C52 or 87C52 part will do fine for experimenting, but if you do not have a programmer for 8051 family of MCU-s, Atmel also has a AT89S8252 (8052 compatible chip with 2K of EEPROM built in) with a serial programming interface which makes building a programmer much easier."

Simple PWM controller - with 555

This 555 timer based PWM controller features almost 0..100% pulse width regulation using R1, while keeping the oscillator frequency relatively stable. The frequency is dependent on values of R1 and C1, values shown will give a frequency range from about 170 to 200 Hz. Any 555 chip will do, CMOS is fine as well.

Local copy of David Tait's PIC archive

Most of these files are related in some way to my simple PIC16C84 programmer for IBM compatible PCs (download pic84pgm.zip and pic84v05.zip). You may find one or two packages that have more to offer though.

Adding More Digital I/O to your 16-Bit Experimenter Kit 

16-Bit Experimenter Kit - Nuts and Volts

If you’ve been following the 16-Bit Micro Experimenter series in Nuts & Volts, you are already familiar with its solderless breadboard environment and the fully programmable 10 line I/O expansion bus that comes with the kit. The 10 lines can be assigned to be digital, analog or even connected to any of the PIC24F Microcontroller’s internal extensive peripheral set (i.e. dual UART, five CCP modules, ADC, Real time Clock Calendar, dual SPI, and dual I2C).

The Mini-Bench Supply

A small power supply with +5V, +12V, and -12V outputs is a handy thing to have around when you’re breadboarding circuits with both op-amps and digital ICs. You would want a switching regulator for efficiency, but linear regulators for low noise. Plus, it should be easy to build and relatively inexpensive.

The Thunderchief project, released in March 2004, was the first runoffgroove.com circuit that was developed using the tubes-to-FETs process. Enlightened and inspired by Doug Hammond's excellent Meteor circuit, we used the same approach in an effort to capture some of the legendary magic of the Marshall Super Lead. The circuit's performance pleased us, but there were issues.

A Geiger–Müller tube consists of a tube filled with a low-pressure (~0.1 Atm) inert gas. (Helium, Neon, Argon,...). The GM-Tube has a coaxial shape, where the inner conductor (Anode) is biased with a high voltage (~500V) relative to the outer conductor (Cathode). The Tube has a window (left side) made of mica.

Homebrew Geiger Müller Counter

This GM-Counter is build on 2 PCB's. One is a standard high Voltage generating circuit, whilst the second is a Counter based on an ATMega16™ which also handles serial Communication with a host (Environmental Control).

A Tiny Computer on Arduino Footprint

pcDuino is a high performance, cost effective mini PC platform that runs PC like OS such as Ubuntu Linux. It outputs its screen to HDMI enabled TV or monitor via the built in HDMI interface.

The platform could run full blown PC like OS with easy to use tool chain and compatible with the popular Arduino ecosystem such as Arduino Shields and open source projects etc.  It can also run Android 4.0 ICS.

A Tiny Computer on Arduino Footprint

Early this year, LinkSprite released a powerful mini PC platform that combines the benefit of an ARM based mini PC and Arduino ecosystem: pcDuino, which represents pc + Arduino. pcDuino is pin to pin compatible with Arduino so that existing Arduino shields can be installed on pcDuino with a simple translation board (T-board). By being compatible with Arduino ecosystem, pcDuino is a platform that bridges the power of open software linux and the power of open hardware.

Use Arduino Uno with pcDuino

Use Arduino Uno with pcDuino

pcDuino has all the hardware interface that Arduino Uno has to offer.  Still, there are chances that people run pcDuino just as a mini PC and use Arduino UNO together with it. All the Arduino UNO programming can be done by running Arduino IDE on pcDuino.
