DIY synth-making workshops starting soon!

I’ve just opened bookings for another round of DIY synth-making workshops.


The first class I am going to offer this year is to build your own Nebulophone: a super sweet stylus synth from US outfit Bleep Labs. I built my first Nebulophone a year ago and I still use it all the time: it is heaps of fun to play and packs a lot of punch for its size. It has a lot of cool features like an LFO, analogue vactrol filter, arpegiator and a sequencer: which basically means you can make heaps of different noises from lush melodies to full-on audio devastation.

Tools, parts, and instruction will be provided – no experience necessary. The class takes about 2.5 hours, and I keep the numbers down to 5 or 6 students at a time so you will get plenty of personal attention. The class will give you a good introduction to the basic theoretical and practical elements of electronics, without overloading you with the boring and confusing details.

Cost is $95+b.f. which is less than what it would cost to purchase a finished Nebulophone, and you get a class thrown in for free!


You can book your spot in the class here. I’ll be adding more dates as the classes fill up so let me know if there’s a specific date/time that works for you and I’ll try to work in with you.

The first round of classes will be in Wellington, NZ, but I’m heading over to Australia later in the year so let me know if you want me to come to your town. I’m also toying with the idea of doing a few workshops in Whanganui and Auckland, if there’s interest.

Other classes for 2012

If you want to take a class but the Nebulophone doesn’t float your boat, I am currently scouting for other options, like maybe the Autonomous Bassline Generator. Or maybe you’d like to build you own little battery powered guitar amp. I’m open to suggestions!

If you’ve got some kids that might like to learn about electronics, I’m looking at running a Klackerlaken workshop soon too. Drop me a line if you’re interested, I reckon it’s going to be a blast!


If you haven’t seen them, check the sweet videos Lekrmoi made about the workshops last year.

Holidays hiatus + DIY Synth classes for 2012

It’s been a great year for Rich Decibels. I’ve been flat out like a lizard drinking, and now it’s time to catch a breath. I’m taking a break over summer, but the classes will be back again from about March.

Introducing a whole swag of people to the delights of DIY synth building has been a blast, and I’m really looking forward to meeting more of you geeks-in-waiting next year. I’m planning to take this show on the road so if you are anywhere in NZ or Aus and you’re interested in learning about electronics and audio and DIY, drop me a line ( and I’ll let you know when bookings are open again.

For more info on the classes see my previous posts on the topic.

Thanks for your support this year!

Nebulophone workshops for November

This round of workshops sold out pretty quickly, so I’ve opened up bookings for another 2 classes in November. If you’ve been thinking about a class but didn’t get a chance to sign up before I sold out, make your booking here ASAP. Thanks ladies and dudes! Tell your friends!

P.S. here’s another LEKRMOI video of some good people enjoying a workshop last week:

The kits arrived from Bleep Labs this week and LEKRMOI came round to film me assembling the first one. If you want a Nebulophone you can sign up to take a class to build your own, or buy a finished one direct from Bleep Labs.

I’m currently seeking expressions of interest for a series of hands-on audio electronics workshops. Update: due to more than 50 people getting in touch (thanks people!) the classes are now full steam ahead. Read on for booking information.

I’ve teamed up with US outfit Bleep Labs to bring you two very cool projects: the Nebulophone and PicoPaso.

The workshops are starting in September and will be held at my new workspace in the Digital Fabrication Council HQ in Wellington. Tools, parts, and instruction will be provided – no experience necessary. Cost is $50+b.f. for the PicoPaso project and $90+b.f. for the Nebulophone. That’s less than what it would cost to purchase a finished Nebulophone, and you get a class thrown in for free!

The PicoPaso is a quick build, so the class will only take an hour or two. The Nebulophone is a bit bigger so you’re looking at 2-3 hours.

The booking system is now online: go here to book for the Nebulophone class and here for PicoPaso.

CALH 2011 DIY Synth Making Workshop

I ran my first workshop series over three days at Camp A Low Hum this year, teaching about 100 people how to make bleepy noises and blinky lights. I got to meet a lot of great people and infect a couple of them with the DIY electronics bug. I’m now in the process of refining my teaching materials and parts kits (supplied by the very rad Mind Kits) and then I will be running more workshops at my place in Wellington, and selling the kits online. For now you can download the tutorial booklets in their current state: booklet #1, #2. If you want to be notified when the next workshops will be running or when the kits will be for sale send me an email or leave a comment.
