I would really like some generic project cases that are in the form of a "wall wart" power supply with a UK plug, and include a built in power supply.

Ryan Castellucci :nonbinary_flag:

@gsuberland Well, poo. This feels like a market opportunity. A slightly less generic version could include an ESP32 in addition to the power supply in the enclosure.

Would also be nice for something like a raspberry pi zero.

Could easily offer variants with US and EU plugs as well.

Maybe certification is the barrier?

@gsuberland I had a couple sheevaplugs (and later, a guruplug) back in the day, they were lovely little pieces of kit.

@ryanc I think if I was going to make something like this to cover the market gap I'd adapt an existing isolated AC-DC 5V design and have it in a sealed mains section, with a DC passthrough to the actual enclosure area where users touch stuff. seems like UL cert would be much easier then, because it's not really any different from a USB charger, unless there's some specific category of mains-involved devboard/enclosure product that invokes stricter requirements.

Ryan Castellucci :nonbinary_flag:

@gsuberland There's apparently a "Sheeva64" now, but it's $150 (up from $89 when it was released in 2019!?) which seems like a poor value. The WiFi version is listed as $175 but out of stock.

@ryanc yeah, just absurd pricing.

Graham Sutherland / Polynomial

@ryanc given that it's possible to make isolated 5V/1A AC-DC converters and an entire molded enclosure to fit it and sell them for under £5/pc (I've bought GaN USB-C chargers for under £3.50/pc at qty10) I feel like it should be well within the bounds of reality to be able to build and sell a mains-supplied enclosure suitable for a NodeMCU-style ESP32 devboard for under £15/pc even with the lower overall production volumes.

Ryan Castellucci :nonbinary_flag:

@gsuberland this would be very much "shut up and take my money" territory if it were a nice high quality power supply that output a clean 5V.

Ryan Castellucci :nonbinary_flag:

@gsuberland Exactly! Please, someone, do this, I will back your Kickstarter or crowd supply thing.

Graham Sutherland / Polynomial

@ryanc a premium version where they integrate two pushbuttons and an LED (either bi-colour or WS2812) would be a great upsell too.

Ryan Castellucci :nonbinary_flag:

@gsuberland That would be delightful.

@ryanc I had one of these mini-computers.

Had WiFi, Ethernet, USB, VPN support, and a power adapter.
Wish I hadn't lost it!
