This is my first UV printed build. The Hydra Delay is a multi-head drum-style digital delay designed by Mr PedalPCB and includes 24LC32A EEPROM with Hydra algorithm preloaded. It uses the Spin FV-1 chip for processing the digital signal. I purchased the PCB with the FV-1 preinstalled. I have since gotten a little more experience with soldering SMD components and may try to do the next one myself. This also used 1/8W resistors so it has lots of little pieces.
I am still getting used to trying to use a multihead delay. There are a lot of combinations that can be made with the head switches.
I used the Hydra logo because… well… it just fit. I am happy with the way the UV printing came out and this started me on creating the tutorial for UV printing at Tayda.
