DIY Projects I : The Beginning

I bought my first prototyping board (or breadboard) and some jumper-wires last week, it's time for me to start learning about electronics and electonic circuits.

The board i got was of the Velleman brand, and to be sure i had enough room on it i bought one of the bigger boards, still for under 20 Euro's.
I also bought a small Velleman Voice Changer Kit (MK171 - 9,95 Euro) , the only audio-related DIY-project i could find to experiment with. Like i said earlier this stuff is quite new to me, and my first attempt will be the mounting of all the parts of the kit onto the breadboard. This seems like a good practice for me to learn more about the components and their functions.

I did learn a lot on YouTube last weeks about the basics of breadboarding and electonic components, and there are a few good (and free) tutorials on the MIT OpenCourseware site ( both video's from lecture 12 are highly interesting and deal with basic sound creation with electonics ) The 559 pages thick lecture notes PDF  that completes this course is also free available at the site, and features the whole course on paper.
The kit is a voice changing kit that can basicly changes your voice into a high, low or robotvoice. I haven't heard yet how it will sound, but the idea and basic modification possibilities are looking great.

I see this as a sort of a side-project, that will hopefully merge into my A-100 system at one point and i'm looking forward on how it will sound. I'll keep you updated.


  1. Very cool again, interested how it'll work out (and sound, of course).

  2. @Marc It does look familiar, with the electronic components as modules, wired together with tiny patchcables. But it is a bit more complicated with all the different diodes,resistors and capacitors.

  3. Great place to start Pierre. I use a similar breadboard for my early development. It will be worth getting a dual power supply, scope and a reasonably good DMM if you don't already have them. If you want any help with selection then let me know. Have fun Pierre!!
