It is indeed true that trying to sell ones electronics takes a lot of time doing other things than developing electronics.
I don't know how it is outside of Europe, but here we have a rule called "Waste Electrical and Electronic Equipment" (WEEE). That means that you don't sell electronics, you sell electronic waste
. The idea behind this concept is a good one, but the implementation was done by some crazy ... heads.
The problem with this rule is that you have to provide means of waste disposal if you sell electronics. You can either do it on you own. That means joining the "WEEE lottery". If you win (winner is chosen once a year), you get a container with around 3 tons of electronical waste delivered to your home. It is now your job to dispose this waste properly. Costs around 1500 Euro (USD 1920,-).
Or you can join some kind of club which manages disposal for you. You pay an annual fee and don't have to care.
The next thing in line is that you have to register every device you try to sell to another kind of club
. This costs, depending on the device, a minimum of 400 Euro (USD 512,-).
You can, maybe, avoid this whole procedure by selling solder-it-yourself-kits instead of assembled devices.
Only a lawyer (who costs another heap of money) can answer this question
.
So the situation in Europe is everything else but hobbyist salesman friendly when it comes to selling electronics.
I don't remember the exact numbers, but if I recall correctly, conforming to the law, I would have to pay something around 2000,- Euro (USD 2560,-) to sell just one small kit
. Company fees and taxes not included. Crazy.
You can, of course, find a bigger partner who registers your device and manages sales etc.
Or you can keep doing it as a hobby and don't care about any of these crazy laws
.
How is it in Australia?
