Hi peeps, new to the forum! So while in lockdown i’ve put my time to good use and finally started my Kosmo project. The case is built from pine off cuts and some eurorack rails I had from an old case, its painted with ronseal wood stain i had left over from another project, total cost £0. If you wanted to build one it would probably cost about £40. The section at the bottom will hold a transformer and power supply.
The filter is a direct copy of Sams Simple Low Pass filter, I didnt go for the highpass mod as I dont use it that much, my only mod was to add a simple 100k input attenuator. I found the filter can be quite senstive to input level and its alway handy to have an attenuator. The filter is mainly built from cannibalized and cheap parts from China, total cost including the panel was £10. If you wanted to build from scratch i’d say about £20.
