Scripting Language Rapidly Develops A Clock

In the past, you might very well have started programming in Basic. It wasn’t very powerful language and it was difficult to build big projects with, but it was simple to learn, easy to use, and the interpreter made it easy to try things out without a big investment of time. Today you are more likely to get started using something like an Arduino, but it is easy to miss the accessible language and immediate feedback when you are doing simple projects. Annex WiFi RDS (Rapid Development Suite) is a scripting language for the ESP8266 that isn’t quite Basic, but it shares a lot of the same attributes. One example project from [cicciocb] is a scrolling dot matrix LED clock.

The code is really simple:

' Simple program using Annex and a MAX7219 dot matrix module
' by cicciocb 2019
'Set 4 8x8 displays with GPIO15 as CS pin
MAXSCROLL.SETUP 4, 15
INTENSITY = 5
'Set the first message with Annex
MAXSCROLL.PRINT "Annex"
MAXSCROLL.SHOW 31, INTENSITY
PAUSE 1000
'Set the refresh rate of the display (50 msec) - lower values -> scroll faster
TIMER0 50, SCROLLME
WAIT

SCROLLME:
'Scroll the display with the intensity defined before
MAXSCROLL.SCROLL INTENSITY 
' Set the text with the Date and Time
MAXSCROLL.TEXT DATE$ + " " + TIME$
RETURN

Of course, one reason it is simple is that Annex has a built-in set up for the LED drivers (MAXSCROLL). It also integrates with a remote web browser very easily, so you can embed HTML output in your projects.

If you look at the project’s main page, there is support for a lot of things including devices such as Neopixels, servos, LCDs, and temperature sensors. There’s also support for a lot of protocols and algorithms ranging from MQTT to PID controllers.

If you really miss Basic, you can use it on the web. Not to mention, that QuickBasic is still floating around.

The Flexible Permanence of Copper Tape Circuits

Somewhere between shoving components into a breadboard temporarily and committing them to a piece of protoboard or a PCB lies the copper tape method. This flexible Manhattan-style method of circuitry formed the basis for [Bunnie Huang]’s Chibitronics startup, and has since inspired many to stop etching boards and start fetching hoards of copper tape. [Hales] hit the ground running when he learned about this method , and has made many a copper tape circuit in the last year or so. He offers several nice tips on his site that speak from experience with this method, and he’ll even show you how to easily work an SMD breakout board into the mix. Generally speaking, [Hales] prefers plywood as the substrate to paper or cardboard for durability. He starts by drawing out the circuit and planning where all the tape traces will go and how wide they need to be. Then he lays out copper traces and pads, rubs the tape against the substrate to make it adhere strongly, and reinforces joints and laps w...
