Why not dim the LEDs by using a higher value resistor? A lot of people default a few hundred ohms, when (at least indoors) modern LEDs are plainly visible (although dimmer) with even a 2.2-4.7k resistor in series.

Oh shit, that's something I didn't see coming! Inline motherfucking c!

So a build that would be like the bigram builds I used to do (at some point, the toolchain stopped working, and then I was forced to rebuild the system by amazon and forgot how to set it up anyway), only it would auto-detect whether that RAM was actually there? That would be really cool
An esp32 build that had 64K jsvars would be pretty cool. Would finally be hard to run out of ram on espruino.

If you've got 4mb of PSRAM to play with, why wouldn't one make the whole 64K jsvars permitted by the 16-bit addressing available?

I found that to get the webserver to work on esp8266, I had to delay starting the webserver for a few seconds after startup.

Interesting that they vanished - I got one too before they disappeared.
A nearly identical board is available - but it has the parts mounted directly on it, and no nice metal shield:

Does this mean that one can t do Wi-Fi update from ones that use 4MB to 4MB-c1?

I just thought I'd let people know about an issue I'd run into:
With DIO, code executes somewhere in the neighborhood of 30-50% slower (I haven't timed it precisely) vs QIO. And you can't really tell if the board you bought has it wired as QIO or DIO until you try to flash it (the QIO capable ESP12 modules have "QIO" printed on the underside, but you can't see that if they're soldered in).
For my pingpong light controllers, I realized this after I had a bunch made with DIO modules (they have to all run at the same speed, and I'd like the QIO ones to run faster), so I've been taking the DIO modules off of my WeMos D1 Mini's with a torch and soldering a QIO one in it's place....

I don't think you need to specify that when flashing over wifi (my understanding is that it continues using whatever settings it was last manually flashed with) - just like you don't specify 4MB when flashing over wifi.
I'm Dr. Azzy
I live and work in the People's Republic of Cambridge, near Boston, MA. I test the web gateway and web development framework for a database software firm for a living. I'm in my late 20's. I own pinball machines, with all the maintenance that entails, and have made modifications to them as well. I also play pinball competitively.
I play (well, not so much anymore) Ragnarok Online, and wrote the AzzyAI homunculus and mercenary AI.
In addition to the Espruino, I own 2 Linortek Fargo units (these are microcontrollers with ethernet ports, that run a webserver which controls relays - nothing you couldn't do with an espruino, but wrapped up very nicely, with a decent web interface). I use one of them for lighting-control in my bedroom. I also have boatloads of other electronic parts, many used/pulls, and many of them manufactured before I was born.
My plans with Espruino include a remote monitoring system for a summer cottage, more advanced lighting control and environment monitoring in my apartment.
I'm not a real doctor (I'd be happy to write you a prescription - but it'll be on the back of a cocktail napkin, and it'll be for a cocktail);
