i was really interested in the Shruthi xt, however for this project I don’t want to have to navigate component ordering yet. I’m reading into 4ms now, thank you!!
unfortunately no wrist strap in the kit… another item to order
I emailed Soma labs to ask if they would accommodate a lyra 8 fx diy kit or panel+ pcb. finger’s crossed.
And then test equipment when you flub, or if you’re doing your own design. A good multimeter of course. But the list then grows and gets more expensive.
We don’t pay VAT, just shipping and possibly import duties. But duties aren’t typically assessed on goods under $800, IIRC. (This is also true if you are a tourist in Europe. Save your receipts and get your VAT back at the airport)
I’m glad I spent $70 or so on a nice ExTech DMM. When I next get back into DIY, I’ll start out with a nice four channel 'scope.
I don’t think spending $400 on a power supply is necessary, but an accurate power supply and a decent multichannel 'scope will help reduce my fumbling with circuits. And also, cool gear.
I started some DIY experimentation last year and took the hard way by learning everything from scratch and breadboard/prototype mostly everything myself. There’s plenty of easy to do noise generating projects to be found. A search for “lunetta style synths” might give you an idea. With a little tweaks these can also be built with CV-inputs and made track well over 2-3 octaves or so.
If I’d start over again there’s some traps to avoid: Never buy any components in bulk. You’ll end up with countless resistors, caps, etc in values you’ll never need. Choose wisely. Don’t try to be perfect.
With regards to power supply: 9V batteries are absolutely fine as a start. There’s possibilities to improvise dual-rail (AC) power with few components.
So I’ve recently taken an interest in this topic after I noticed how many pieces of gear were based on Teensy. It made me wonder what was so special about this Teensy board and whether I could experiment with it to do some music projects. They seem to have a series of “shields” you can attach to the Teensy board to add more and more functionality.
I’m comfortable on the software programming side but I’ve never soldered a single thing in my life. So I recently bought some scrap PCBs and a bunch of through hole headers to practice on. No matter what I’m sure I will learn some things as the hardware/electronics side has always seemed intimidating.
It’s incredible to me how some of these one man operations take things a step further and fabricate cases and productionize their creations for sale. It seems like an enormous amount of work and I can’t even contemplate all the steps involved.
The DIY lyra is probably not the best project to start with. Massive amount of parts and more then one pcb to connect.
Don’t worry about wearing ESD wristbands too much unless touching intergrated circuits like ad converters. Most ESD sensitive components will be delivered in ESD plastics so you know which one to be careful with.
DIY is a very cool stuff, I made around 30 40 modules in eurorack format in a couple of years
But :
Be prepared to face problems that will be sometime solved but also remain sometime unsolved. You will need a lot of patience and time to understand your problems and mistakes.
You get a lot of satisfaction using your finished and working stuff to make some music but it will take you a lot of time. Time that you will not have to make music. (it can be also very addictive)
You will NOT save money
The components crisis that will long at least till 2023 is not cool for synth DIY
