Regarding kits ...
Eagle-eyed viewers will have noticed that I have started offering kits - it has taken a while, but it would appear that the demand is there and I fully understand that people enjoy the challenge of putting electronic kits together and it's certainly very satisfying to fire up something you've put together and have it work without expiring with a puff of magic smoke.
Kits are distinct from PCB/panel sets in that you'll get a bunch of components as well as the PCB(s) and panel(s). I offer kits in two distinct flavours:
Full kits are exactly what they say on the tin - you'll get the necessary PCBs, panels and components required to put the module together. All you need to do is solder everything up. I don't provide instructions per-se, but each item listing will hav a link to a github repository which will contain an appropriate schematic and bill of materials (BOM)
There are a couple of kits (eg. passive mult, dual attenuator) which are so simple that they don't really need a BOM or schematic.
- Partial kits should also be self-explanatory - you'll get most of the components you need, but there'll be a few that you need to provide yourself in order to complete the module: generally, these parts will be pots, jacks and/or knobs. Think of these as a half-way house between a full kit and a straight PCB/panel set.
But what if my kit has missing parts?
A fair question - first of all, if you've got a partial kit then make sure that the parts that are missing aren't the ones that you need to provide yourself. In the case of a full kit it usually means that I've goofed - one of the reasons I resisted doing kits for so long is that picking components for a kit is a monumental pain and it's very easy to make mistakes.
If you do have a genuinely missing part then there are a couple of avenues open - if it's something like a resistor or capacitor then there's a very good chance you'll have something suitable in your bits box; it's rare that component values are set in stone and a value 'there or thereabouts' will usually work without impacting performance - eg. using a 4.7uF electrolytic instead of 10uF will not cause things to mysteriously explode and the sky to fall in. The exception to this is for modules which rely on timing circuits where a different valued component may affect performance.
If the missing item is a pot, knob, jack or similar then I'll probably be able to mail replacement items to you - for other components (passives, ICs etc.) I will likely arrange to have components sent to you directly from my suppliers as it works out a lot cheaper.
In extremis, I'll do you a partial refund to cover any missing bits and you can make arrangements to source them yourself.
