What's NewI intend to maintain a list of updates to my site on this page, if I can remember to update it every time... 25 Sept 2011 - Some PHP processing brought on board! Crude PHP-based navigation bar added at left of most pages, and general structure re-vamped, though old HTML links should still work - if you find something that doesn't work (it will be a minor miracle if I haven't made a mistake or two editing over 50 pages!), please let me know by getting in touch. 24 Aug 2011 - Plan B M14 Dual Voltage Processor mod Simple resistor changes (mostly!) to improve the crosfade (Linked from 'mods page'.) 12 Mar 2011 - Monotron filter pole analysis A new page of analysis of the Monotron filter poles, which is also largely applicable to the Korg35-based lowpass filters. (Linked from the 'Korg page'.) 30 Jan 2011 - Teleton SAQ-206B Amplifier A new page dedicated to the Teleton SAQ-206B amplifier, with a few new scans and photos. (Linked from the 'Stereo LED VU Meter'.) 27 Dec 2010 - Korg Monotron component layout An annotated photo showing the component layout of the Monotron. (Linked from the 'Korg page'.) 28 Nov 2010 - Plan B M17 Triple Event Timer mods A couple of simple mods to correct and improve the operation of the Triple Event Timer (Linked from 'mods page'.) 26 Nov 2010 - M28 Tap Clock mods A new page detailing the main inverter mod for the M28 upgrade: my instructions for Rev 1.0 boards were already posted at Phil Gallo's site—here I have added those of Rev 1.2 boards. Also a bit about missing resistor R5 on the main M28 page. (Linked from the main M28 page.) 01 Nov 2010 - Clock and Reset for the A-161 Adding a small board to provide clock and reset signals to the A-161, making it stand-alone from the A-160. (Linked from 'mods page'.) 26 Sep 2010 - Plan B M10 modifications A page of modifications for the Plan B M10 Polyphonic Envelope. (Linked from 'mods page'.) 29 Jul 2010 - Plan B M28 upgrade sound samples Some simple sound files added to show the upgraded M28's new capabilities. (Linked from the main M28 page.) 20 Jun 2010 - Plan B M28 mods Details of two further simple mods to the Plan B M28 (Linked from 'mods page'.) 28 May 2010 - PE Minisonic scans A complete set of scans of the Practical Electronics magazine Minisonic synthesizer. (Linked from 'synth main'.) 22 May 2010 - Plan B M28 synchronization upgrade A new firmware offering and modification to improve the performance of the 'phase lock' feature. (Linked from 'mods page'.) 21 Mar 2010 - Plan B M15 sine wave adjustment mod A tricky modification to the Plan B Model 15 VCO to improve the sine wave adjustment method and waveshape. (Linked from 'mods page'.) 31 Jan 2010 - LMF100 Switched-Capacitor Filter I finally got around to recording a simple sample of the clock noise of the LMF100 Switched-Capacitor Filter, when modulated with a slow-running LFO. 11 Jan 2010 - How the Serge VCS works A detailed look at the workings of the Serge VCS (Linked from 'synth main'.) 14 Dec 2009 - Comprehensive TB-303 Diode Ladder Model A new page giving some extra data on my large transfer function for the TB-303 filter (Linked from 'diode ladder filters'.) 14 Dec 2009 - Site map Added a crude site map to maybe help with navigation. 4 Oct 2009 - LMF100 Switched-Capacitor Filter I have completely re-written the LMF100 Switched-Capacitor Filter page, to correctly refer to the LMF100 chip actually used (it was originally written around the MF10 chip), and given a lot of design information (though it is not 100% complete yet). (Linked from 'DIY modules'.) 29 Sept 2009 - Plan B M9 bleed-through mod A simple modification to the Plan B Model 9 Mixer to help alleviate the bleed-through problem. (Linked from 'mods page'.) 25 Sept 2009 - New Facebook photo album Link to some new snaps at Facebook, of a short break to North Wales. (Linked from 'photos'.) 28 Aug 2009 - Resonance Tuning for the Digital Moog Filter Link added to Robin Schmidt's paper on the Moog ladder filter. 09 Aug 2009 - Behold the Computer Revolution Another brief trivia page added, on the never-ceasing frustrations of working with computers. 05 Aug 2009 - Arp 2500 brochure Scan of an Arp 2500 brochure (a 5.1meg PDF file), courtesy of Ben Ward. (Linked from 'synth brochures'.) 02 Aug 2009 - Arp 2500 poster Scan of a large Arp 2500 poster (a 5.6meg JPEG file). (Linked from 'synth brochures'.) 03 Feb 2009 - Identifying dodgy IEC power inlets How to tell if your Doepfer G3/G6 case is possibly fitted with a dodgy IEC power inlet, which have been known to fail. (Linked from 'mods page'.) 17 Jan 2009 - Teleton SAQ206B amplifier schematic added I've been surprised by the number of hits I get from people searching on 'SAQ206B', so I have scanned the schematic (7.7Meg file) that I have had for years (the copy is not brilliant, but scanned at 300dpi it looks to be mostly readable). (Linked from 'Stereo LED VU Meter'.) 25 Dec 2008 - New Facebook skiing photos album Link to a Facebook album of a selection of my old skiing photographs, taken over a number of years. (Linked from 'photos'.) 10 Dec 2008 - this night wounds time A brief page of King Crimson trivia added. 7 Dec 2008 - Page of Korg MS-10/MS-20 filter related material added Reference to my MS20 study moved to a separate page, along with many links relating to the Korg35, the MS-10 and MS-20 filters, and clones/copies of them etc. (Linked from 'synth main'.) 25 Oct 2008 - Moog Ladder paper - big update! A major re-write of my Moog ladder filter paper, which now includes diode ladders, poles, frequency responses and more (Linked from 'synth main'.) 20 Oct 2008 - Correction to Diode Ladder Filter page Strikeout of an erroneous statement (proper correction to follow once I've got a better handle on it!) 13 Oct 2008 - New Facebook photo album Link to some new snaps at Facebook, of a recent weekend visit to York. (Linked from 'photos'.) 19 Sept 2008 - Research paper links A page of links to some interesting research papers on ladder filters.
