Grat stuff right there!! I might actually take your documentation as inspiration for my uni project.. basically i have a professor who is going to help me build a whole modular synth from the ground up and right now im starting out.. and a "simple" 8-step sequencer is my first move into that direction!

just to say, you should check the 4022 or 4017 i dont get the point in using an arduino herem but that's me (the interesting part in the arduino for this woulkd be the code study witch sould make an easy to undertand example). for 8-16 (or more if you chaion several) steps check "baby sequencer, and then add what ever controls you want using transistor switches per step (you can do without though) for power stability. Anyone interested in etching/building 8-16-or more steps sequencer, feel free to let me know i'll; share my pcb layouts... sequencers are a great project to learn and understand some basics of logic electronics, and i'm pretty shure it must be interesting and not that hard to program to an arduino.

Arduino enables varied stepping modes: Reversed, up and down, etc., which would be difficult at best with a 4017.
@baddriddimworkshop21 күн бұрын
@@analog_output yeah but i think i remember you can do that with a 4022 or another way (i just happen to have used 4017's because i started building a baby seq the first time and went from there, but i got a few books since...), i'de just need to check my books but it's doable with logic and i'm shure you know that. BTW i found a way to achieve randomness; you'll need a s&h with the output sent to a 16 stage lvl merter (or 8 or else, if its two 10 stage meters in series in a chip reduce input lvl and number of meter stages to suit needs), each levels of the meter being tied to one step, with a separate clock to the s&h you can do cool things that way... personally, random, and back and fourth is not that interesting to me the way i build music but once again that's me. these days i am after sequencing drums with one line (i prefer sevewral like igor did but, technically...), using two 8 latch chips (push on push off) chips per chanel if 16 steps (or more for more...), theory is easy (once you know your chips), i just need to give it a built now...

Today i finished the sample and hold circuit and works like a charm. Now i have this great idea i like to share but i do not know how to approach this. What if..... we would add voltage per octave tracking so that the random notes/voltages are played in minor or major or other musical scale? A random minor/major like sequencer.? I hope someone or maybe Mr Holmes himself could use this. Have a nice day

The legendary Bob Pease called breadboards 'the white slab of trouble.' I'm not sure I'd go to quite this much work. I don't know how often I need a 10 ppm match. (I usually use emitter resistors, which hides some of the mismatch.) The last batches of DMMT5401's and DMMT5551's that I got in all seem to have a Vbe match within about 300 microvolts (The data sheet says 1 mV typical, 2mV max, so maybe I got lucky, or maybe their production process is better than they claim.) Having both transistors in one package is convenient. I solder it into a breakout board, epoxy a tiny RTD on the back of the package, and glue on a piece of blue foam. An opamp and a couple of resistors, and I have a temperature compensated matched pair suitable for a 1000:1 log converter. For currrent mirrors and current references, I really like the REF200. Searching for transistor matches for that application is worth a lot more than ten bucks of my time.

I'm RX light blinks with note on info, but I'm getting no voltage change readings on any CV output. I'm using elkayem's exact code. I'm using benjiao modular schematic I'm really confused. Any suggestions? Thanks

Very nise! I also have a DSO 138, I have long wanted to combine it with my experiences with music and homemade devices (I absolutely agree with you that initially it does not look presentable) But there are several not good moments in it. These are slide switches and tact buttons. They were initially of disgusting quality. Although they still work today, but with deviations. I will also upgrade the oscilloscope. I have an idea to make something like my own form factor. Similar to Eurorack but a little smaller. The useful area of the box is 34.5 by 28.5 centimeters. Yes, it’s very small, but that’s the beauty of it. The box itself is an all wooden box in excellent condition from a portable reel to reel tape recorder. With a chic, massive, fold-back stainless steel handle. This box will contain a simple set of homemade and converted modules. The front panel is styled to resemble instruments from the 60s and 70s. Micro knobs (turned from aluminum) and mini potentiometers are many original ones from the times of the USSR. From the mixing console "Venets 32-01". Something like this. You have an interesting channel! Subscribed! I wish you Health, Love, Goodness and Happiness! Шикарно! Тоже есть дсо 138 давно хотел его обьеденить со своми опытами с музыкой и самодельными устройствами (абсолютно согласен с Вами что изначально он выглядит не презентабельно) Но и есть в нем несколько не хороших моментов. Это ползунковые переключатели и тактовые кнопки. Они изначально были отвратительного качества. Хотя по сегодня работают но с отклонениями. Буду тоже осциллоскоп модернизировать. У Меня есть мысль сделать что-то типа своего форм фактора. Аналог еврорэка но немного меньше. Полезная площадь ящика 34,5 на 28,5 сантиметров. Да очень маленькая но в этом и есть прелесть. Сам ящик это полностью деревянный ящик в прекрасном состоянии от переносного катушечного магнитофона. С шикарной массивной складной назад ручкой из нержавеющей стали. Вот в этом ящике и будет простой набор самодельных и переделанных модулей. Передняя панель стильлизованна под приборы под 60-70 года. Микро ручки (точёные из аллюминия) и мини потенциометры ест много оригинальные со времён СССР. От микшерного пульта "Венец 32-01". Как то так. У Вас интересный канал! Подписался! Вам Здоровья,Любви,Добра и Счастья!

Fantastic, thanks for sharing Rich! I've had one of those oscilloscopes for years with the intention to build it into a module. I have a case for it and so it's been very low on my priority list. You've done nearly all the thinking for me for when I finally get around to doing this! I like the idea of separating the main circuit board from the display with a ribbon cable.

Hackaday just posted a link to kzbin.info/www/bejne/fpPMl2loo69ojsk in which the builder had some trouble with apparently fake multiplier chips that were prone to overheating.
