For a few months I tried to emulate @jasonmade's wonderful year-long project where he made a thing
every day. Later on it morphed into part of
This started off as a danger-paper-bag. It’s basically this but with this , in a tin ( code ).
The local shop had a bunch of different ones and I love pickled chili.
Trip to the scrapstore: ping pong balls, sticky eyes and an unusual 4-sey eggbox.
I wanted this to be a machine-gun type thing (I have a lot of earplugs), but completely failed. Failure’s good, right? (bike pump, earplugs, a straw and a rubber band).
Sticky magnets and sticky eyes (I didn’t do the graffiti though)
A shonkbot as a chocolate box, request from DS. I added ultrasonic sensing too later ( code is here ).
A vibrating ball powered by 2 x CR2032s with an Arduino nano clone, an Adafruit LIS3DH and a Lilypad Vibe . I wondered about putting it in a balloon but couldn’t find one ( code ).
it’s been a tiring week
Name by DS.
Accelerometer, Wimos D1 mini, and much swearing at websockets. The video initially got flagged up as inappropriate O_o. Code .
Sloes picked at Sea Mills, and then we got lost in the woods.
Javascript face tracker with the video hidden, projected with a tiny projector onto A4 tracing paper. Very slightly modified clmtrackr example .
Tiny motors salvaged from tiny quadcopters.

Visioned by DB, bits foraged from him (tiny quadcopter motors, battery, yellow bit from inside of a Kinder Surprise). And a balloon from Asda. The wires keep breaking on the motors…
Also, it’s not a submarine. I did try weighting it but that part needs more work.
A variant of 14, inspired by talking to JW, king of the shonky robot competition at hackspace one Christmas.
Or “replacement cat”. Visioned by DS. It’s really upset the actual cat though.
The idea was that supposed to use photocells somehow. But it doesn’t. These are all basically Hebocon -style crappy robots.
Controlled with a light sensor.
These are a bit samey. Hopefully something more interesting tomorrow.
Make your wool even more of a mess!
Like the submarine but with Asda’s finest helium.
It’s very quiet. Apart from the motor.
Wakes you up when you’ve not moved for a while. But the buzzing is too soft to notice when on battery. Looks like I need a better circuit .
I had to make one after seeing the lampshade left out for rubbish.
Visioned by RS. I was really just his temporary arms. Cool bit of cable wrap left on my desk though.
Mediocre resources in a hotel room.
Black bread roll, edible flower (marigold?) and rocket, with pea-pureé eyes.

A version of 22 with cutlery. Realised late on it should be glasses of water, but some initial experiments indicate that it could be a biggish job to convert it.
It was a bit slow at first but I just added more batteries. (DC motor, wire, cable collector tubes, 3 x CR2032, rubber bands, tape).
Same code as 11 , this time projected on a window for halloween, with a USB camera, a thicker line and the projector balanced on a stepladder. But no-one got close enough to notice…
Video by JK - thanks!

Used webrtc (on a pi3), which is rather a roundabout way of doing it, but I had it handy. Wifi didn’t work well under water so had to be on an extension cable, rendering it rather non-waterproof. Idea suggested by DB.
I’m struggling today…spent a long time fiddling with different things, not terribly happy with it.
I wanted this to climb things, but it just fell off. I did find a useful cable I made earlier USB to pos/neg that I can use for more reliable power sources though.
DM suggested paperclip day.

Made from junk left on my desk and my poor abused servo.
Works well! but I was trying to make an elastic-band propelled plane.
Laser-cut, using gimp and Inkscape and several train journeys, but it’s too fragile. Learnings: get the height of the laser z-axis right. Make the design bigger. Make the connection bits fatter.
This was going to be an Icosahedron but I ran out of glue. The end of a long day of fails of various kinds, including two making-fails.

Discoveries: ESP8266s don’t work (need different value resistors?), but arduinos do . Knees and wooden floors and coir mats stop it from working, acrylic and bubblewrap work as an insulator.
A bit of tent-cord, a little slip and some coffee-stirrers, and some pinking-sheared paper.
ESP8266 Squix eink ( code ). I have the lite version - which needs something like this to connect it - with a DTR - ( instructions ).
The light-up glove was a lovely present :-D
Thanks RB for the box!
A force-sensitive resistor (thanks MP) and some ball bearings (thanks RS). No, I don’t know why….
This took far too long.
I have a plan for a walking contraption using this, but I won’t have time to do it tonight and it probably won’t work anyway… :-)
I did some beat detection for another thing - this is just that code hooked up to websockets and serial port. Thanks DB for the name.
Now with a maraca and poorly implemented real-time browser-side “beat” detection.
Not very funky. Had to tweak the high and low-pass parameters a bit to pick up the music. You still can’t hear the maracas over the servo noise.
not to scale, or to time, and I thought the red led was white
Video made and materials lent by DB - thanks!
Using squib - code
Supposed to be fully automatic. Boo.

We’re going just servos, arduinos and paper for a month
I wanted to make it spin with the kettle steam but that didn’t work at all.

Could I get it to laser cut and etch the same piece? could I bollocks.
Using this with bits of this and this esp32 hardware Thanks to @njh for the gateway.
More info but not quite right.
A variant of protective crocodile clip.

Wrong transistors :-(

With IR photoresistors so it’s not that great!
Straw from Pieminster. Spent most of the day at a Naked Gun marathon at the Cube so not much time…
Concept by Damian.
Dan’s idea. It sinks :-)
Works out of water though!

It loves lights!
This time with proper light sensors.
Alan unimpressed
Hacking bitsy again.
Worked first time! (for once). Basic layout from here .
Not as fun as the digital one.

Danbri’s idea, kind of, and Damian helped me film it.

To start 2019, half a GPT-2 bot, to make prompts for #makevember
collaboration with Dylan, Damian and Mat
2 (bonus) collaboration with Anya
Taking the bot prompter literally
6: paperwork sorter
sad robot (poc'Kit things only)
face- (in fact nose-) detection in javascript (face-api.js) but hosted on a wemos esp8266 (using ESPAsyncWebServer) (for no reason I can adequately explain)
is adding nodding
pitch shifting my automated voice (using https://github.com/urtzurd/html-audio )
errm singing?? (this time based on
https://github.com/mmckegg/soundbank-pitch-shift
)
# makevember 13 Tried this nice tutorial on tflite on the Sparkfun Edge https://codelabs.developers.google.com/codelabs/sparkfun-tensorflow/#0 … (though it doesn’t like my voice or something - not shown: a full minute of me saying “yes” and it going “eh?”)
Speech to text on a Raspberry Pi 3, using https://github.com/gooofy/zamia-speech … - the crappy mic is most at fault here, not zamia or kaldi.
voice activated “robot” with zamia and a seeed respeaker 4
17 apple feeder for the birds
A robot for barnoid . “Victory is for now!” (Thank you mistertim )
sweary hammer
December 23rd, 2019 3:37amplaying with an eCO2 sensor https://learn.adafruit.com/adafruit-sgp30-gas-tvoc-eco2-mox-sensor/
I’d hoped to slack-enable the sweary hammer ( https://twitter.com/libbymiller/status/1196557807224524800… ), but instead I just learned about debugging esp8266s. Also making quite a mess of my libraries. bah.
zamia / kaldi / pi3 again but with my voice rather than barnoid ’s.
lunchtime make: unreliable wifi doorbell
two fails: servos not strong enough to move my lovely lamp, and voice synth on a pi 4 crashes the pi.
raspberry pi zero with a button using a dt overlay (using http://blog.gegg.us/2017/01/setting-up-a-gpio-button-keyboard-on-a-raspberry-pi/… )
fixed my # mynaturewatch camera, which was a splendid idea
Frogger with a button (frogger from https://www.raspberrypi.org/blog/code-a-frogger-style-road-crossing-game-wireframe-27/)
wotsit detector using open CV (thanks @ mistertim for filming!)
using a better power supply fixed 23′s problems synthesising my voice. I can synthesise utterances using our tweaked version of https://github.com/Kyubyong/dc_tts on a Pi4. Synthesising “hello” takes 3 minutes 11 seconds :-) (takes about 30 secs on my mac book pro)
