How to Synth DIY part 4 ANYONE can Build the 555 LFO!

Yes thats right! Anyone can build the 555 timer LFO… and to prove it, I let my 8 year old daughter do it! This was Elly’s first time soldering and she enjoyed it immensely (even with a minor mishap!) If she can jump on the Synth DIY horse, SO CAN YOU!


The 555 Timer Oscillator from Synthrotek will be a modulation source for our upcoming Delay Dev kit circuit. (and other circuits as we will keep this modular!)

the Idea is to use this to modulate the rate of the delay board.

For this project, we won’t be hooking up power just yet as I plan on daisy chaining the power off of another circuit first.

we also will not solder on the attenuator just yet as we will be using wire so that we can place the board more efficiently inside of the case. You can buy the 555 Timer LFO HERE—> Synthrotek Store  it’s only $15.

Animodule Lil Monster VCO Eurorack module gets taken for a spin!

Animodule is a small Eurorack and MU format analog synthesizer module maker. Based out of Pennsylvania, they create hand built analog masterpieces that shake houses and dominate mixes.  The Lil Monster VCO is a hand built Triangle core OTA based oscillator with HUGE pulse width modulation and excellent features such as sync, and exponential / linear FM. It’s calibrated for 1v per octave so it will work with most standard analog synths. The Circuit board is etched using a C&C machine so these are not some mass market hunks of junk. These modules are built to last and really feel well built. the knobs have a strong sturdy placement the pots are not wiggly it just feels like someone actually put care into what they were making. Respect it.

Take a listen to its intense sound in this short video here and stay tuned for more articles featuring this manufacturer.
