    Select Case

    See post #16 in this thread, for some great example code by Hippy: https://picaxeforum.co.uk/threads/direct-rs232-connection-08m2-14m2.32726/

    US sources for products

    I'm in California, and have ordered a lot of the basic chips (08M2, 14M2, etc.) from RobotShop. Shipping is reasonable and fast. https://www.robotshop.com/

    650 nm 200-250 mw Laser not work with 20M2

    To start, please share a schematic of your circuit diagram.

    DRPlayer with 08M2 chip

    That solution is also discussed in this thread, using a rotary switch: https://picaxeforum.co.uk/threads/rotary-switch-with-readadc.31708/ It works well!

    Determine resistor value

    Take a look at this thread, there are a couple of good solutions there: https://picaxeforum.co.uk/threads/rotary-switch-with-readadc.31708/#post-329045

    PWM odd variable reading

    It has been common for quite awhile to think of visual scripting tools (such as Blockly) as just for beginners, and that after learning how to structure code, you should move on to "real" coding. But this type of scripting tool has moved beyond the educational area and is now used in a lot of...

    Problem getting a 18m2 program to run on a 20m2

    Agree with above...the 18M2 is the odd duck vs. the 08M2, 14M2 and the 20M2. The last 3 share similar pin locations, but the 18M2 is different.

    LED Current Limiting Resistor Value

    Sparkfun came up with a clever way to adjust the resistor that controls LED brightness. See this blog post: https://www.sparkfun.com/news/5461 I assembled a couple of these, will post a quick video soon.

    PC board fabs

    Another option is OpenSCAD, which allows you to use code to define a project. Here's are some box makers on Thingiverse: https://www.thingiverse.com/thing:1264391 https://www.thingiverse.com/thing:58944 Search Thingiverse for "box maker" to find more. OpenSCAD is here: https://openscad.org/

    Optical Glove Controller using LDR

    Thanks for the link to that YouTube video, he has lots of other clever stuff (mostly with puzzles for escape rooms).

    Optical Glove Controller using LDR

    A high school student came up with a very clever, inexpensive way to make a glove controller: https://hackaday.io/project/189165-optical-glove-controller-using-ldr

    JQ8900 audio board

    I haven't heard of it before, but I found this: https://www.scribd.com/document/494627850/HDSD-JQ8900-16p-MANUAL

    PC board fabs

    It usually takes a few days for the US shipping company to hand it off to your local post office. Then it arrives quickly.
