MuViTools: MuVisu

In this video I describe the current version of MuVisu, a program I’ve made to help learning musical instruments. It is insprired by interactive music games like Guitar Hero, Rock Band or Rocksmith. It’s focused on an universal approach of high customizabillity to make it usable for a wide scope of musical instruments as well as different learning-settings and -goals.

The project is hosted here: https://github.com/Piesi/MuviTools/

 

My PCB-Milling-Toolchain

DSC01802

PCB-milling is an interesting alternative to the traditional PCB-etching method, because it doesn’t involve chemicals and the mill can also be used to drill the holes an cut out the board. I think i t’s also faster (never did etching). On the downside, the process is not easy to handle and it’s hard to level the surface of the PCB precisely to get a consistant quality of the traces. I haven’t enough practise to tell how fast the tool wears out and how the costs add up compared to the traditional etching method. But I finally managed to get nice results from PCB-milling and like to share the setup with you by describing the toolchain I used. The tools are all open source, by the way:)

DIY Amp Circuits

I’m currently looking for an analog post stage circuit
for my Techtar, to apply some “real” amp-sounds.

There are many DIY amp circuit websites out there. Here I start to list
some sites which are most useful to me.

Catarina Mota (ted-)talks about open materials

A wonderful talk about smart materials and the maker culture.
I think it contains lots of well nailed statements.

“…There was a time when we understood how things work and how they were made, so we could build and repair them… Many of these do it yourself practises were lost during the second half of the 20th century. But know the maker community and the open source model are bringing this kind of knowledge about how things work and what they’re made of back into our lives…”

crazy experiments: motors, frames and propellers

DSC08162

  I got a crazylfie micro quadcopter for my birthday and love playing around with this remarkable open development kit. Yes, it’s not just a very small but powerful quadcopter, it is also comes with all the design files and the tools necessary to modify the software and/or hardware, which in it’s current state is already quite mature. Having said this, if you look for a ready to go quad copter with all cutting edge features – look elsewhere. While the hardware with it’s 10dof sensors, fast cpu and expandability is – considering it’s size – quite complete, there are still a lot things to be developed hard- but foremost software wise. But this is not a downside, because the product crazyflie is not exactly a quad copter, it is a quad copter construction kit with every bells and whistles whith a blog, a wiki, a forum with a whole quad copter construction community, inviting everyone to participate. And for that I’m just loving it.
