welcome @limor and @pt !
live vid is here folks'
Prof. Fartsparkle3:02 PM
hah. the talking heads are cute
thank you @Sophi Kravitz and the hackaday community for having me on this hackchat about creative robotics!@
its a robot roadshow!
Stephen Tranovich3:04 PM
The robot co-hosts are SO GOOD
oh yeah... let's start!!
Limor, can you intro yourself to all of us?
so i’m the lead engineer and owner of adafruit
thats our open source software and hardware factory here in nyc
so the machines are running you can even hear them on the livestream and maybe see some people loading up the feeders
yeah those machines sound loud
clean and well oiled machines are happy machines
this chat feeds my ADD- video and text both in two locations!!
we're here for a half hour! hit me up with the Q's!
Hey hey. :-) I'm back. Well fed machines too :-)
give us the lowdown on how CRICKIT works
Rob Ray joined the room.3:07 PM
yessss hardware details
crickit started as a project fcalled seesaw
basically we see so many different chips on the market which is great
but some like the esp8266 don’t have, say, analog in
and some don’t have a lot of timers or pwm like the raspi
i was seeing people want to build animatronics, creative bots
but got hit with "ugh this hardware i using doesnt have 5 PWMs or ADC or the ability to drive neopixels"
so seesaw was the solution for that
its a i2c -> anything concerter
now you can buy i2c counters, like ADCs, DACs, PWMs etc
but by the time you add em all up, it’s like $4 BOM
its waaay cheaper to have a cortex m0 that HAS ALL THIS STUFF FOR FREE
kevin forsythe joined the room.3:10 PM
and then you just write a transport
so we did
NOW we can do robots
because i wanted to keep the price low enough that you aren’t spending hundreds of $ - you can take advantage of seesaw and then pair it with your fav micro
whether that be esp82, esp32, raspi, microbit, teensy, feather etc
cause its just I2C
and everything every in the history of everything has I2C master

I always wondered why these dedicated ICs are often so expensive even though they are less complicated than the MCU which does the same and more
Michael Welling3:11 PM
voice to text anyone?
except for the ESP8266
phil and i went to dimsum
Orlando Hoilett3:11 PM
@Michael Welling nah. this is way cooler
and we decided lest make a robot platfor for all his awesome ideas!
Orlando Hoilett3:11 PM
Watching the broadcast as well as paying attention to the chat is pretty hilarious. Lol.
we literlly sketched on a napkin
Frank Buss3:11 PM
some PICs don't have hardware I2C either
adn came up with the octogon
you can bitbang i2c it isnt the end of the world
you just need to have open drain pins
if you dont - seesaw is not for you
Frank Buss3:12 PM
right, but then you can't do much else with a small PIC :-)
frank, dont use a PIC 12C509
we've got more chips now ;)
Frank Buss3:13 PM
lol, I know
Paul Stoffregen3:13 PM
haha, not 1995 anymore!
ok any more Qs
Boian Mitov3:14 PM
So do you want it also programmable with Visuino ? ;-)
Michael Welling3:14 PM
bitbang all things
how do you manage power?
Boian, sure! we hvae code in C/C++ and python
Orlando Hoilett3:14 PM
What's the driver current on the platform?
what @Orlando Hoilett said
OMG THE POWER IS THE BEST PART
