We're working on that. It will most likely be done with a comb binding (plastic ring type that sits open nice an flat on your workbench).

Comb binding is cool. It means you can wrap your pages round more easily Very Happy

Fair? When is life ever 'fair' ? Shocked Laughing

I'm off to the Isle of Wight to spend a week in a static caravan on some remote farm Very Happy

Beware of rules on the Isle of Wight! Lunch from 12-2pm only, dinner 7-10pm only and that sort of thing. I have never seen a component supplier there!

I'll be getting a copy of this one. Sounds great.

A couple of questions though.

Since it's "An Analog Synthesizer for the 21st Century" can we safely assume there will be no hard to get obsolete parts?

Will it include PCB art work?

Yes to the first question, no to the second. Wink

I'm going to post a parts list, so you'll be able to see what's involved. There is a 3080 in the LFO (along with an 8038), but the 3080 isn't hard to find (ask on the forums, or even try Futurlec). Also, as Thomas pointed out, you can sub a 13700 for the 3080.

As far as PCB artwork, I'm working on PCBs for some of the more ambitious modules (the mega LFO is one example), but these will be double sided professional boards. I may try some single-sided home etch friendly layouts, but there are only so many hours in the day!

And thanks for the interest!

Sounds good. 3080's I can get over the counter here so that's OK. I'm sure I'll be able to find the others.

I once ordered some NOS obsolete chip from a guy in germany. When it arrived it was stamped 'made in singapore'. Kind of like it had taken a long vacation.

Hey, ready-made pcb's sound good too (can't wait for the Mankato as it is, and now you're turning up the drool flow even more).

Hi All,

I've got a parts list for all the circuits in An Analog Synthesizer for the 21 Century, anybody want to see it?

The book will be ready very soon, so I prepared the parts list in case anyone wants to start checking their inventory Wink Let me know and I'll post a copy here.

Ciao!

Please do post the parts list, it will make my life easier.

Also, would it be possible to post the double sided pcb layouts as well? I know this sounds crazy but I wouldn't mind either running the layers through my router or even trying it the laser transfer way.

Man, I can't wait for this book!

Okay All,

Here we go! This is a complete parts list for all the schematics in Thomas Henry's An Analog Synthesizer for the 21st Century. Please note that this is preliminary, and I'm still double checking for errors before publishing the book. Should be pretty darned close though. Let me know if you have any questions, or if anything looks weird.

Just waiting for a proof copy from the printers. As soon as I make sure that's okay, then we're off to the races!

Hey Boys and Girls,

Thomas' new book is now available! We're experimenting with a new print service to produce printed hardcopy versions, and we hope everybody likes the results. The new book is Thomas' "An Analog Synthesizer for the 21st Century." If you're not already familiar with it, here's a short description:

"A collection of schematics for a complete, accurate and versatile analog synthesizer. Designed by well-known synthesizer guru, Thomas Henry, this is a comprehensive set of plans guaranteed to delight and challenge the advanced DIY enthusiast."

Basically, unlike Thomas' other books, this isn't a step by step book with detailed instructions. Rather, this is a set of schematics for a variety of modules and is meant for the more advanced DIYer. This includes schematics and parts lists for:
*Power Supply
*XR-2206 based VCO (with some neat VC wave skew features)
*LM-13700 based VCO
*State Variable VCF
*VCA
*ADSR
*VC Noise Source
*VC Phase Shifter
*Deluxe LFO (with the features of Thomas' older Super Controller and then some)
*Sample and Hold
*Along with a suggested Patchover scheme for creating a "normalized" synth somewhat like the ARP2600 where the synth can be run without patch cords but those connections can be easily overridden with patch cords if desired.

The book can be previewed and ordered at
http://www.lulu.com/content/1065518

You can also just go to Lulu.com and search for "synthesizer," we come up first on the list. The printed version is $20 + shipping, and represents years of work and refinement by Thomas Henry. If you check out the preview, don't be put off by the rather 'grainy' appearance of the first schematic (power supply). This is a result of the preview conversion, but the printed version looks very very nice. The book also comes with a spiral bound backing so that it will lie flat on your work bench.

Thanks for your time and bandwidth. Servo out!
