Skis
About the Skis PCB
Skis is an open source PCB design by kraakenstuff, published on GitHub. It is a 2-layer board measuring 29.2 × 109.2 mm, with 96 components from 37 distinct parts.
Other key parts include the TL074 and LM13700. By type, the board carries 38 resistors, 18 capacitors, 11 connectors, 10 transistors, 6 jumpers and 4 switches.
From the project
The SMD, 6HP version of Bastl Skis. Includes sliders :)
This is smd version of Bastl Skis v1. Main differences are:
It has skis (two sliders) vs. no skis in Bastl version 6HP vs. 5HP, for obvious, OCD reasons Range switch vs. range backside jumper (although this switch works as a jumper - instead of going from freq0 to freq1, and then from freq1 to freq2 in the second position, it goes from freq0 to freq1, and then from freq0 to freq2) Version 2 of Bastl Skis has decay CV input, and this one doesn't have it * Version 1 of Bastl Skis was THT and had two sandwiched boards, and this one is SMT in one board.
