@allObjects, your English is excellent, hence your JS must be exquisite!

Instead of cutting that sensor in half, try using it like a laser beam sensor...attach a small mirror to the other side of the goal, aim the sensor at the mirror and then detect when the ball breaks the beam. Might work.

eh...I just looked at the datasheet. Distance to reflector needs to be about 14mm or less. If you cut it in half, you'd get about 28mm, just over an inch, probably not enough...

Unless... the ball is shiny enough to reflect back to the sensor. You could put a sensor on each side of the goal. I don't think you can know what works until you try it.

Very thoroughly detailed explanation, thank you! Lots of materials needed and lots of time I bet, something not undertaken lightly, but very nice results.
Thank you!

you can probably just delete my comment from your RAM, I doubt it illuminates anything...

Wow! I haven't half your knowledge or talent, and then I see your poor soldering iron. Like Michelangelo painting with toothpicks, while I have the best boar bristle brushes but can't paint a stick figure.
Please tell us how you made that board! I know it's probably simple to you, but out of my understanding atm. I'm guessing you could just post a link...
Are those cross-braces in the first pic? To hold it steady while you ????
What is the metal sheet for in the second pic? Soldering?
What did you coat the traces with in the third pic?
Thanks!

// minor nitpick...

function f(scope) { scope.someFunc(); }
...
f(window);

// works with window = this;, but not with replace window.

My chrome seems to be broken, pressing the link button does nothing for me :(

I'm too green, I can't even envision how the pico will be used with castellations around 3 sides plus 3 interior pin holes.

Here is the latest picture on KickStarter for anyone interested...

If a pad is measured by width from the edge of one pad over to the edge of the next pad, then it is 0.05". I guess it would have been simpler to say 'center to center' huh? The guy selling those chips claims you can solder those pads without glasses...he must have better eyes and steadier hands than I.

I don't know much about board manufacturing, but I just got these in the mail. They were wrapped in thin foil and I almost tossed them because I couldn't believe there was anything in there. When I put on my glasses, I noticed they had castellations. Just thought I would share because they were so tiny.

Dimensions are 0.24 x 0.79 x 0.07 inches or 6.1 x 20.1 x 1.8 mm.

Hi @ak! I haven't had time yet to actually do any experimenting; just know that I want to play with LoRa. Heck, I don't even have an Espruino yet, where are my Pico's Gordon? JK

Regarding base stations...you have a number of these LoRa nodes out there, all acting asynchronously, something needs to be 'ON' and listening all the time that they can talk to, right?

This guy (below) uses a base station which is basically another LoRa node but plugs through usb to a computer running an app that gathers transmissions, logs, takes stats, connects to internet, etc. He says you don't really so much program the nodes, you configure them in the app, and it is the app where you add your code. I am guessing that the nodes 'wake' up and transmit their pin status to the app which tells them what to do next, but that is just my guess until I get my hands on a few. Thinking about it though, it is an interesting way to go. The nodes all have one simple program, not requiring much cpu or memory or battery power or need to re-program out in the field etc. The KS project failed, but he is making them available online anyhow.

Hmmm, I tried to make a 'link', but nothing was happening, so:

I have some RFM69HW's (long range version of RFM69W) coming in next year but this is all virgin territory for me, so it'll be slow going.

awww crap, I didn't read carefully enough...

Still waiting on mine...

LOL, you might be almost as old as I am :)

Crossbreeding?

is that from trace()? I looked at that but really didn't see anything like "2.5 memory units".

@DrAzzy, how can you tell how much memory is used?

I actually did find that one...I seem to have a recollection that it was a pretty comprehensive list, perhaps I dreamed it :)

As I am learning JavaScript, I want to be aware of the stuff that won't be available to me when using Espruino. Somewhere I saw Gordan had posted some sort of list of what had not been implemented in Espruino...anyone know where that info is?
I apologize if it is somewhere readily available, I tried to search for it...
Thanks!

I am probably too ignorant to suggest anything...but I'm willing to look silly if it helps me learn :)

Could you put some code at the top of onInit() which does an early exit if a button is held down?
