MIDIGEN – A (belated) LEMS postscript

This short article discusses an add-on to the following:

The Brute: A 3-channel Audio Amplifier For Leslie Speaker Emulation.
Treslie: 3-Phase Leslie Speaker System.
LEM: Leslie Emulation Control System using PIC Microcontroller (18F26K20) based on Pequeno board, (Arduino-alike) and 3 DACs.

Shortly after completing LEMS, The Brute and Treslie, (see links above) it became apparent to me, that [...]

PCB Milling Diary – April 8th 2012

A great deal of what we see on the Web, project-wise, is the ‘finished’ product. Every questionable decision has been ‘revisioned’, and what warts remain are carefully hidden, or presented as ‘features’. Yeah, I know this is a pretty cynical view, but unfortunately, nearer the truth, than even I would like to admit.
One of the [...]

Microchip’s MRF24J40MA SDO Buffer Hell

I am annoyed. So much so, that I’ve downed tools to scribble this.

I recently spent some considerable time attempting to get a non-documented SGN6210 radio module to work. In the end I decided there were too many unknowns, and it was better to go for a more ‘mainline’ product, so I bought two MRF24J40MA modules [...]

LEMS – A Leslie Speaker Emulation System

Updated: 16th July 2011 @ 3:02am
This post describes the design and construction of a Leslie Speaker Emulation System (LEMS) control unit, based around an 18F26K20 PIC Microcontroller. The unit is intended to be used to split an audio signal into 3 phases, amplitude modulate these and feed to a Leslie Speaker Emulation driver unit [...]

MPLABX – Beta 6.0 software? I give it Alpha–

As I started writing, the newly-installed copy of MPLABX was using up over 50% of my PC’s CPU time, and half-way through this sentence I had to kill it dead using Task Manager.
It looked promising – but NetBeans does look pretty. And I successfully converted and built a current MPLAB 8 project for a PIC18F26K20. [...]

Ultra-easy use of 64-pin TQFP PIC Microcontrollers using TQFP-to-DIP PCB from VOTI

VOTI TQFP-to-DIL Header with PIC and ICSP fitted

A while ago I purchased a batch of 18F6620 TQFP PIC Microcontrollers at a ridiculously low price. The barrier to use of TQFP packages is, of course mounting these SMD packages effectively alongside the ‘normal’ components enthusiasts tend to use. At the time I set about and [...]
