(With apologies to Chistopher Marlowe) Now the bath in my new home in Portugal had a concrete relationship… Solid support? Further, it would have been difficult for a medium-sized Portuguese child to get wet in it, so I decided on a replacement, the installation of which would take place on completion of pipework being installed for the [...] December 23rd, 2013 | Tags: bathtime - any takers?, Brick shithouse engineering, Tabuas Casa | Category: Mechanical Engineering, Workshop |

The TREND T4 variable-speed (11-32,500 rpm) router provides an affordable alternative to high-cost ER11, ER16 and ER20 High-speed spindles. As part of my project to convert my SIEG Milling machine to CNC, I wanted to see for myself how easy it would be to fit a high-speed spindle to the Mill at reasonable cost. I have [...] June 11th, 2012 | Tags: Economic High_Speed Mill Spindle, High-Speed Spindle, Isolation Routing, Milling Machine, SIEG X1L High-Speed Spindle, T4 Router, TREND T4 Router | Category: Hackit & Bodge, Mechanical Engineering, PCB Isolation Routing, Workshop |

Updated @ 16:28 13th April 2012 I’m playing catch-up here. The contents of this post refer to work over two days old, delay in writing it up is due to other, more pressing matters.

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.

This post describes the design and construction of a 3-phase loudspeaker intended for Leslie Speaker emulation. The unit is intended to be driven by a 3-channel audio amplifier The Brute, which in turn is controlled by LEMS, a micro-controller based control system, the construction of which both are described in companion posts. Final tests on [...] July 18th, 2011 | Tags: 3-channel speaker, 3-phase speaker, Leslie Speaker, Leslie Speaker Emulation | Category: Audio, Electronics, Guitar Projects, Mechanical Engineering, Music, Workshop |

This post describes the design and construction of a 3-channel, 30 watts per channel, audio amplifier. Although my amp incorporates two antique HY60 power modules, construction details are given for construction using the modern TDA2050A, capable of yielding 32 watts. The amplifier is intended to be used as a Leslie Speaker Emulation driver unit, delivering [...] June 20th, 2011 | Tags: 3-channel amplifier, 60's architecture, Brutalist, emulation, HY60, Leslie Speaker, TDA2050A | Category: Audio, Electronics, Guitar Projects, Mechanical Engineering, Music, Retro Gear, Workshop |
