By Emilie S. Førrisdal In todays lab we learned how to build a device that lets you hear electromagnetic fields using a kit called Electrosluch. The electrosluch kit contains all the basic components needed to make the device. It uses… Continue Reading →

Building the Elektrosluch

Author: William Davison Today I finished building the Elektrosluch instrument which should be able to create sounds by detecting electromagnetic fields. I followed the picture tutorial then checked with the schematics afterwords to see if all was well. An emphasis… Continue Reading →

Elektroslush – What we learnt

Author – Matthew London In the last two labs we have learnt how to build an elektroslush, on a breadboard and a perfboard. By following the schematic on the lab materials I was able to successfully build a prototype on… Continue Reading →


Author: Eddie Clijsen It was interesting to create this instrument as well as learn how to troubleshoot electronic circuits using both a multimeter and an oscilloscope. Also, looking into the methods for developing the project further, for example using a… Continue Reading →

Cable Wiring – Minimising Noise

Authors: Marcus, Matthew and William Today we learned how to wire up cables in different configurations, for example: mono to mono jack, Jack to XLR and XLR to TRS. We also went over some tips on reducing noise being transmitted… Continue Reading →

Cable Making Workshop

Today we discussed how to make different cables. The connections we looked at are: XLR male to XLR female XLR to TRS Mono jack to mono jack TRS to mono jack We discussed how to solder the cables and how… Continue Reading →

What we learnt today

Authors: Michal Kais & Eddie Clijsen Designing wiring for different connections, for example: Mono jack to mono jack XLR male to XLR female XLR to TRS jack Balanced XLR or TRS jack to unbalanced mono jack

Tutorial 3: Noise

In todays lab we explored the ways to calculate the noise generated by conductors. All conductors create noise at temperatures above Absolute Zero(-273 degrees celcius). How much noise is created depends on three factors: Temperature, bandwidth and resistance. The signal… Continue Reading →

What we learnt today

We first revised the formulas for working out the frequency with the period and vice versa, and the RMS of a signal. We then figured out how to calculate what time delay you need to cancel a signal, and that… Continue Reading →

What we learnt today:

Authors: Michal Kais, Eddie Clijsen RMS measures a constant power of a wave How phasing and flanging works A wave can be cancelled by adding another wave that’s exactly the same, but delayed by 1/2T
