Delay No More - NonLinearCircuits build notes.

The saying "Delay No More" is a great ideal to live by.
And for those of you who have spent any time in Hong Kong, you might also recognize it by its local slang meaning.. "Delay no more" sounds similar to the Cantonese foul words (Diu lay lo mo) which translate as "fuck your mother".
Seldom used seriously "Delay no more" appears in writing as a joke among Hong Kong people. There is even a fashion brand in Hong Kong producing T-shirts with "DelayNoMore" on it.


I'm sure Andrew knew none of this when he picked a name for his new delay module. :-)


Here are the build notes:
http://www.sdiy.org/pinky/data/DelayNoMore%20build%20notes.pdf

All the SMDs are passive ... just caps & resistors. So building this puppy should be pretty easy.
(Be careful not to heat the caps too much).

The DNM uses the PT2399 which is a great chip for DIY. It's almost a whole guitar pedal by itself.
According to Princeton (the manufacturer) it is a echo audio processor IC utilizing CMOS Technology which is equipped with ADC and DAC, high sampling frequency and an internal memory of 44K.



It also features an internal VCO circuit in the system clock, thereby, making the frequency easily adjustable.
Cool Man !

First some virgin pics of the PCB.

Both sides require SMD components. Solder these on first.


Headers, resistors, caps next.
Next the BC 547 trannie, the 78L05 (+5v voltage regulator) and the vactrol.
I'm using a Silonex NS 32

K = Cathode.

Now the pots & jacks. There are six linear 100k pots , one 1M linear  and a single 50k linear.

Don't forget to solder the ground tabs with scrap wire.
Lastly do the LED.
Beautiful !!! Time to stand back and admire.
And she sounds very distinctive. esp for such a small module. Another sound effect in your arsenal.

I'm thinking of putting this into one of my Buchla cases. As the CV input is isolated by a vactrol, plugging in 10v - 15v Buchla voltage levels should be fine. This module is not just for Eurorack.

Buchla 200e & a Roland TR 909

Some fun yesterday. 

Cobramatic & I paired two of our favourite instruments:


The Buchla 200e & Roland's TR-909


The 909 is the master clock. (all midi)  sent to the 225e -- the top left module in the pic below.

The timing to the 250e sequencer was super tight... all midi clocked via Buchla's internal bus

Mutable Instruments Grids - hack - adding clock & Random gate

It's Sat afternoon and we are feeling pretty good ...having each just consumed half a Kangaroo and two bottles of red wine.
The wine on the right is a 1990 vintage port from Steins in Mudgee NSW. If I remember correctly, they have a fabulous motorcycle museum there.


And on the left is a Tollana Cabernet Sav from 1995. (Eden Valley, South Australia). Both excellent wines !!!

In such a frame of mind there seems nothing better to do than hack a perfectly good Mutable Instruments
module.

Paul (Cobramatic) tells me it's a easy one and he won't even hold me responsible if I mess it up :-)

He must have really liked the wine I served.

Anyway, it turned out to be dead simple and I highly recommend this if you own a MI Grids.


There are 3 points on the back of the module: Random Gate, Clock & Ground.
Solder  a wire to each and the other ends to two jacks.
The ground of course is shared by both jacks.


Deciding where to mount the jacks is a bit tricky ... Lots of SMD components .... decided to place them
between the bottom two jacks on the left.

There you go!

We now have two new outputs ... for clock and random gate. Very useful.

Rolex Explorer history

 
The Rolex Explorer was launched in 1953 to celebrate the historic first successful ascent of Mount Everest by Sir Edmund Hillary and Tenzing Norgay. [1, 2, 3]
It is one of the world's defining utilitarian sports and tool watches. [1, 2]

History and Evolution
  • The 1953 Everest Connection: Following high-altitude expeditions in the late 1940s and early 1950s—including the May 29, 1953 Everest climb where team members wore Rolex Oyster Perpetual chronometers—Rolex capitalized on real-world testing to refine its watches for extreme conditions. [1, 2]
  • Early References (1952–1959): The first watches to carry the Explorer name were the pre-chronometer/precision Reference 6150 and the chronometer-certified Reference 6350 (which introduced the signature 3-6-9 Arabic numeral dial and waffle/honeycomb textures), followed by the Reference 6610. [1, 2]
  • The Long-Running Ref. 1016 (1963–1989): Produced for over 25 years, the Reference 1016 became the backbone of the Explorer lineage, transitioning from glossy "gilt" dials to matte finishes and upgrading its water resistance. [1, 2, 3]
  • Modern Refinement (1989–Present):
    • The Ref. 14270 (1989) introduced a sapphire crystal and the Caliber 3000 movement.
    • The Ref. 214270 (2010) temporarily bumped the case size to 39mm.
    • The current Ref. 124270 (2021) returned to the classic 36mm size and houses the Caliber 3230 movement, alongside two-tone Rolesor options. [1, 2]
  • The Explorer II (1971–Present): Launched with the Ref. 1655, the Explorer II diverged into a larger, 42mm tool watch featuring a fixed 24-hour bezel and an orange 24-hour hand originally designed for speleology (cave exploration). [1, 2, 3, 4]

Significance
  • Pioneer of the Civilian Tool Watch: While earlier watches served military, aviation, or deep-sea diving needs (like the Submariner launched the same year), the Explorer pioneered a purpose-built, rugged timepiece tailored for civilian adventurers and mountaineers. [1, 2]
  • Design Purity: It established a minimalist template—a high-contrast black dial, bold Mercedes hands for maximum luminescence, and prominent 3, 6, and 9 Arabic numerals—that has remained remarkably unchanged for over 70 years. [1, 2]
  • The "One-Watch" Philosophy: Valued for its lack of superfluous complications (no date window, no rotating bezels), the Explorer is widely celebrated by collectors as the ultimate "GADA" (Go Anywhere, Do Anything) watch that bridges formal and casual wear.
