Maker Meeting Short Take – Schlieren imaging!

Check out the latest in our series of outtakes from Workshop 88 Maker Meetings here:

See the rest of the discussion in the original video

The reason behind using the Schlieren system was to find out what we could see while blowing over the top of a plastic pop (soda) bottle. There was quite a bit of discussion and suggestions for experimentation in the original Maker Meeting video.

Maker Meeting March 23, 2021 – ESP8266, Arduinos, and a Dalek

Check out the March 23, 2021 Workshop 88 Maker Meeting here:

ESP8266 interfaced with a keypad

Peter shared the following information about using the Arduino keypad library with the ESP8266after the recording:

There is a pretty good tutorial at https://diyi0t.com/keypad-arduino-esp8266-esp32/

There were two questions I was not able to answer, but I’ve done some more investigation:

  1. If you register a callback function that is invoked when a key is pressed or released, is that based on interrupts?   No.   It ties into the non-blocking getKey() function which is already being called each time through the loop.   If a callback is registered, it will be called by getKey() when appropriate.
  2. Does multi-key support mean that it buffers up a sequence of characters, or does it mean you can press multiple keys (chords) at the same time?   Despite my wrong guess last night, it’s the latter.   The getKeys() function will return a list of up 10 keys that are pressed or released, even if a second (or later) key is pressed before the first ones are released.   Apparently, they do the right magic with pull-ups and only driving one line at a time so that they can do this without diodes on the switches.

Other items shared!

After Peter’s presentation, Jim shared with us how he uses an ESP8266 to control an Arduino. Very cool! At the end, Dave shared with us his progress working on a Dalek build project – including some very nice resin casting!

Massimo’s great talk

MassimoRachelJimTwo members of Workshop 88 went to hear Massimo Banzi’s talk on Arduino, open source hardware and more.  The talk was part of Ge Garage’s Idea Week.  He gave some great stories of the philosophy, joys and problems of putting the Arduino out as open source hardware.

Among many other insights, he described how the fashion industry – with no intellectual property protection – made a lot more money than the entertainment and music industries with all their DRM efforts.  He told of the value of the many iterations of Arduino and how a primary metric of its success was the time between a new user opening the box and getting a useful result.  We learned it was named for a bar where they held many design meetings.  It was a great talk.

SignedArduino0243-300Rachel also scored some excellent networking time with Massimo, including connections that will be very useful in her upcoming trip to the Rome Maker Faire.  Jim brought home a newly autographed Arduino that had run the dollhouse at Rachel’s New York Maker Faire booth.

Hack-A-Thon II 02/06/2010

We’ll be holding a second hackathon 2:00pm-9:00pm Saturday February 6th. A couple projects we’ll be working on are our big near space balloon event and some beer brewing and bottling. As always bring your projects, bring your Arduinos, and bring your excitement!

We’ll be holding it at Jay’s house again, if you’re interested in attending and did not come last time, please contact info@workshop88.com for the address.

Let us know if you’re coming and discuss potential projects on the forum post.

Scanner Challenge, Part 1

CutHere

As part of our first public meeting this Monday, we handed out a bunch of :CueCats to everyone who attended, along with a challenge: tinker with them, see if you can get them to do something fun, and share it with everybody at the next meeting.

I’m planning on using mine to build a handheld barcode scanner based on an Arduino and the touch screen from a Nintendo DS that stopped working a while back.  It may be a bit ambitious, so I’ll probably need help along the way.  I thought it might be helpful for others to see what I’m doing in case they get stuck in their own projects.  The Arduino is in the mail, but while I wait on that, here’s the progress so far.
