Tenderfoot Electronics
It's an annual event. Hopefully I'll return in 2020.
Address : B2F SHINTAISO BLDG No.4, 2-10-12 DOGENZAKA,
SHIBUYA-KU, Tokyo 150-0043 Japan
TEL : 03-6427-810
Directions: Go through the entrance of Shintaiso bldg parking lot located next to the Seven Eleven Dogenzaka Chuo Shop.
Tokyo Tape Music Center
WYWS - While You Were Sleeping (Brisbane, Australia)
As well as the manufacturer's displays, there were electronic performances at night.
Videos of the performers to come.
Star wars - timeline
A brief Star Wars timeline.
These are just the personal records of a Starwars fan & are not by any means complete.
I'll add to this as time goes by.
Thanks to the confusing release of the various movies, their renaming & addition of prequels, etc, it can sometimes be difficult to know where things start & end. thus this attempt to put order to the chaos.
Please let me know if you think I've left out anything really important.

National Art Center Tokyo - Roppongi
You can see the Ginza district and the old Tokyo Tower from there.
If you have limited time in Tokyo, this is a great place to go to get your bearings.
Highly recommended are the National Art center (NACT) and the Mori building.
Address:
7 Chome-22-2 Roppongi, Minato City, Tokyo 106-8558, Japan.
Website:
https://www.nact.jp/english/
The NACT is probably Japan's largest museum
The building is made up of seven enormous column-less display rooms.
Architect: Kisho Kurokawa.
He is one of Japan's leading architects and is one of the founders of the Metabolist Movement (along with Kiyonori Kikutake,and Fumihiko Maki )which fuses architectural structures with organic biology.
Metabolism (/məˈtæbəlɪzəm/, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms..... leading to renewal & organic growth.
Shibuya Crossing - Sat night 16th Nov 2019 - Tokyo Japan
Its a trendy suburb of Tokyo ... very much geared towards the youth & young at heart.
There are lots of nightclubs & designer shops.
Night time is when it really comes alive.
Ginza, in comparison has an older, more sophisticated feel. After the first night
The Shibuya department store,109-2 has the best views (Mags Park) over the crossing.

TT 303 Bass Bot - Higher State of Consciousness - Josh Wink - Jondent remix
Josh Wink's HSOC is one of my favourite acid tracks and it's so simple... just 2 notes : G & B. (the second G note is transposed up from the rest).
Sometimes the simple things in life are the best.
This remix is not intended to be an exact copy.... I used HSOC as a starting point.
Original HSOC video (It"s been described as a porno with great music) LOL: http://youtu.be/VOXw1xz-c8w Thanks to Old Nick for his suggestion.
This is a live remix. I've made it a bit slower than the original.
Sadly I didn't have any scantily clad models at my disposal. :-( Equipment used: Cyclone Analogic's Bass Bot TT-303 for the acid. Korg monotribe (kick drum)
Hard Mod's Ribbon synth - background atmospheric sounds.
The Bass Bot does not receive Roland/DIN Sync so haven't been able to sync it with my TR808.
But the Korg monotribe works a treat. Also, the patterns remain even after the Bott is turned off. This is without batteries. Something the old 303 didn't do. I think this is what is called Non-Volatile memory.
Yamaha FM Chips
(This is only a small selection of the total produced)
Many of these chips are still available and are excellent for DIY projects.
ALM Busy Circuits Akemie’s eurorack modules are made with some of these old Yamaha chips (YMF262 aka OPL3).
These came out around 1983
YM21280 (OPS) operator chip (Yamaha DX7& DX5)

8 algorithms. The envelopes, frequencies and LFOs can be changed to get a good range of FM sounds.
The YM3438 is a modified CMOS version of the YM2612
I recently built a DAFM synth using the YM3438.

1988
YMF262-M(OPL3-L)
Used in many of ALM Busy Circuits Akemie’s eurorack modules... like the castle.
OPL3 stands for FM operator type L. Mostly SMD format. ... really cheap on ebay.
The YMF262 was used in many sound cards, such as the Sound Blaster Pro 2.0,
Sound Blaster 16 ASP and Creative Labs AWE family
Four op FM. .... pairing 2 channels together to create up to six 4 operator FM voices
4 channel sound output

YM2610(OPNB)
used in NeoGeo hardware. Needs an external DAC.Four FM channels
(The YM2610B variant added two extra FM channels for a total of six)
In the original chip, sound comes from 4 different generators, each having their own channels:
- SSG (Software Sound Generator): 3 channels -- compatible with YM2149 (Atari ST)
- FM (Frequency Modulation): 4 channels. 4 operators per channel.
- ADPCM (Sample playback): 7 channels
- Noise : one channel
1994

This is actually a hybrid FM/PCM. It uses 32 channels (4-op).
1994
YMF271 (OPX)
used in Seibu SPI arcade board
Again, its a hybrid FM/PCM chip.
I think there are 9 channels .. can configure the number of operators?? (Up to 4 op)
1994 ??
YMF276-M(OPN2C-upper compatible?)
It's a 6 channel FM synthesizer based on the Yamaha YM2203c.
used in FUJITSU FM TOWNSII

YM2608B(OPNA)
Used in the NEC PC98 ... PC-8801 (1985)/PC-9801 (1986)
16 voices, six FM channels, 4 operators.
Uses the same algorithms as the DX21 ??
----------------------------------------------------------------------

YMF281-D(OPLL Another version?)
Y8950(MSX AUDIO)
-----------------------------------------------------------------------
**** OPL is a FM Operator Type-L
-------------------------------------------
About the different types of Sound chips:
These ICs, were used in arcade game system boards, video game consoles, home computers, and PC sound cards.etc etc.
They are not all FM.
There are 4 main systems:
1. PSG - programmable sound generators
2. Wavetable synthesis
3. FM synthesis
4. Pulse Code Modulation

OTA - Operational Transconductance Amplifiers
I never really studied the circuit till recently so always assumed it was a completely digital design.
It uses a cmos 4069.... its an inverter... but the other part of the circuit is a
CA3080 ... a OTA...Operational Transconductance Amplifier. This is used instead of your standard Op-amp.
I'm sure this is a big part of the sound.
So what is a OTA?
It's a amplifier unlike your standard Op-amp.
What the OTA shares with your common Op-Amp is:
1. a single output.
2. They both have inverting & non-inverting inputs.
3. They both have power lines (V+ & V-)
What makes the OTA different is that it has 2 extra inputs (Ibias & Iabc)
and it's output is a current not a voltage.
So, to put it another way, a OTA is a voltage to current amplifier or a voltage controlled current source.
The OTA can also be viewed as an ideal transistor.
Like a transistor,it has three terminals—
a high impedance input(base)
a low-impedance input/output (emitter)
a current output (collector).
There are loads of circuits that use the OTAs like VCOs, filters, VCAs, waveshapers.
OTA's include:
CA3080 (discontinued)
LM13600 - Texas Instruments (formerly National Semiconductor)
LM13700 - Texas Instruments (formerly National Semiconductor)
MAX435 (obsolete product)
MAX436 (obsolete product)
OPA860 -- Texas instruments (SOIC)
OPA861 -- texas instruments
NE5517 - ON Semiconductor
NJM13660 - New Japan Radio (JRC)
NJM13700 - New Japan Radio (JRC)
V13700 - CoolAudio
BA662A Roland (manufactured by Rohm in the 1970s)*
BA 662B - Roland (manufactured by Rohm in the 1970s)
IR3109
BA6110 - Rohm
* The BA662A is the VCA used in the SH101, TB303, Juno-60, JX-3P, etc etc.
It's used for portamento in the Jupiter 4.
------------------------------------------------
CA3080
Lots of old synths use the CA3080 which is obsolete and can be expensive to buy on the second hand market.
----------------------------------------------------------------------------
LM13700
The LM13700 is basically two CA3080s on one chip. You can also get these in a DIP (through hole) format. There are also conversion circuits that allow you to use a LM13700 in place of the CA3080.
There are lots of manufacturers still making this useful chip. They may have different part numbers, but the design is still the same one designed by Bill Gross & Don Sauer of Texas Instruments (formerly National Semiconductor).
Here is the pinout for a LM13700
We basically have 2 identical op-amps.
This is really good for circuits that require matched pairs of amps.
Pin1
Amplifier Bias input
This sets the level of transconductance.
(the relation between the output & input current).
Pin2
Diode Bias A
Current applied here allows the chip to accept a higher differential input voltage.
This will improve linearity & distortion.
Pin3
Non-inverting input A
Pin4
Inverting Input A
Pin5
Output A
The output of the opamp as a current.
This equals the difference in input voltage between pin 3 & 4 , multiplied by the transconductance.
Pin6
-V
Pin7
Buffer input A
Darlington pair buffer
Pin8
Buffer output A
Darlington pair buffer
