Eurorack Modules: DIY CRT scope

Hi guys, I know it's been a while.
I've fallen behind with updating my blog although I've been active on my facebook and my YouTube pages. Sometime back in 2018 I decided to switch to eurorack as my DIY stuff required a lot of maintenance. I uploaded this video of my current studio recorded with an old crappy camcorder where you get the general idea of the setup:

I've bought several weird modules which sort of fits into my previous aesthetic with vero test-boards, bendable CMOS-chips, tube-amplifiers, CV-controllable tape-player, nixie tube counter and a custom built CRT-scope module I designed in collaboration with a tinkerer from Belarus under the name Ghetto Hacker. 

I stumbled upon this Ghetto Hacker guy where I saw he'd built a module for eurorack with a small CRT from a camcorder, used as an oscilloscope. I paid him for his time and skills to make me one and the result is really amazing, sturdy 3d-printed arm to hold everything in place and a nice black front plate.

 

Here's some video:

Testing module in my own case:

 

 And here's some pix from the build:

If you're interested to see what I'm up to, go follow me on YouTube (Dani Dogenigt) or find Dogenigt on facebook. I think I am going to give a guided tour of my eurorack system so you can see some of the modules in action. Please take care and see you soon!

Yearly recap

All right so it's been over a year since I last made a new post here. A lot has happened in this period.
First of all my .com domain expired and before I got the chance to renew I discovered to my surprise that it'd been bought by someone else, I suspect godaddy does this to get people to negotiate a buy-back fee which is a dirty move so right now you can find this blog on dogenigt.blogspot.com

I've been moving a lot so all my gear and the entire workshop is currently stored in my rural home where I am renovating so I haven't been able to build and produce anything.
I also chose to cancel my studies for my master's degree at the academy of music due to stress and other health issues so my mind hasn't really been focused that much around electronics and music.
I've been more or less homeless over the (harsh scandinavian) winter and staying at friends but I am moving into an old farmhouse with my brother on the 1st of may so my plan is to gather some of my gear and get a small studio going again.

To make a recap of where I left off a year ago,
my DIY modular project was going into all sorts of directions as I was really inspired to do all kinds of raw and untraditional modules.


I got to mounting the magic eye tubes for the 4 channel mixer and the VU-meter nixie tubes for the stereo main out module with EQ for both channels as you can see in the bottom case.
In the top case I mounted volt- and amp-meter for the PSU and a breadboard module with banana jacks for interfacing. This could be a neat little module for testing new circuits and have them ready for experimenting on the go.
The green screen to the far right is actually an old gameboy with backlight with LSDJ cartridge and a vintage magnifier screen from a dias-photo viewer. The red wires going from the gameboy are going to a NES-joypad which I succesfully got working so I'll be able to control the gameboy from afar as the gameboy is enclosed in the case.
On top of the case is my microcassette tape delay and two cassette tape players from a stereo tape deck which I am planning on building into a third case for a tape delay.
On the far right is an old tape player from a car stereo which I want to make into a monophonic tape voice unit with CV-control for the motor to control the pitch.

More to come!

Roberta the Robot v0.1 (voice recognition test)

I want to show you a cute little side-project I am currently brewing on. It's going to be a robot with a

voice recognition shield for Arduino (EasyVR 2.0 Shield). The idea is to have a fully functioning voice controlled robot able to control power relays with motion tracking servo motors for the neck and arms.
Right now I am testing the voice recognition out with responds in both english and danish.

The final idea is shown in the drawing to the right. There will be a lot of challenges involved if I am going to realize all the ideas. I will need a little help from my friends.
