And We Have A Winner!
Today I found out that the Light Painting Buchlaesque photo I posted a couple of weeks ago was selected as picture of the week for the I Dream Of Wires Modular Synthesizer Photo Contest! I’m really excited about that. Check out the post on Matrixsynth or the I Dream Of Wires Facebook page for more…

Light Painting Buchlaesque
Experimented with light painting today. This photo was taken at 40mm with a shutter speed of 20 seconds and an aperture of f14. ISO was at 400. While taking the picture the room was pitch black and I used a small flash light to paint the light during exposure. I entered the I Dream of…

Prototype PCB is here!
Today I received the prototype PCBs for the mutant timbre / modulation section. They’re looking good! The final version will be blue (of course). More to follow soon…

Mutant 259 timbre / modulation index
I’ve been working a while on the timbre section of the Buchla 259 and this week I spent a couple of evenings finishing the PCB design. This is how it looks now. The PCB is the same size as the 258J oscillator and the power connectors are on the same location which makes for easy…

Buchlaesque modular in progress
I’ve been working on my new Buchla inspired modular on and off for some time now and finally had some front panels made. They turned out great and it inspired me to put some more energy into getting the modular done. I already finished the cabinet and rails for mounting the panels six months ago. So, last…

Mutant Buchla 259 timbre section
Lately I’ve been working on building a mutant version (that is: with non-vintage components) of the timbre/symmetry section of the famous Buchla 259 complex waveform generator. I used the schematic Mark Verbos posted on his website as a starting point. I replaced all opamps with the TL072CN. All other components are common resistors (I used…

Buchla 258 Dual Oscillator working
The last couple of days I have been fighting with a DIY variant of the Buchla Dual Oscillator Model 258. I couldn’t get one of the two PCBs to output the right waveforms. Tonight I wired the second PCB and was finally able to fix the first PCB. I will not bore you with the…

Buchla200 custom cabinet almost done
The cabinet is almost done now! It is made out of 18mm Birch plywood and there are 4 layers of Mahogany stain applied now. I still have to do one or two layers of protective lacquer. Today I made four Aluminum rails where the modules will mount to. Unfortunately, I couldn’t finish the last two…

Buchla200 custom cabinet v2.1
Finished the basic structure of the new cabinet today. The cabinet is glued together now so I have to wait until tomorrow for the glue to dry. I changed the side panels a little bit. They are now a fluid line instead of the three angled slopes in the Sketchup design in my previous post.…

Buchla200 custom cabinet v2
I wanted to start working on the cabinet but due to circumstances I didn’t have time today. Instead, I played some more with the design and came up with something better. The footprint of this cabinet is larger than the previous one but it looks much more Buchla. So this is the one I’m going…

Buchla200 custom cabinet
I’m playing around with Google Sketchup and, as a practical exercise, I’m designing a new cabinet for my Buchla 200 clone. I wanted it to be as compact as possible and came up with the design to the left. The height of the cabinet is 616 mm (24.3″), it’s 684 mm (26.9″) wide and 240mm…

The (Buchla) Future of Things to Come…
I worked on a couple of front panel prototypes for my Buchla 200 modules today. I used the same technique as I used for the Buchla 291 clone I’m building: designing in Front Panel Designer, print out on paper and using 3mm scrap wood for the prototype panel. From left to right: Dual Oscilator Model…
