Since my robot is running on a Raspberry Pi, which is now supported by ARC, I decided to evolve my current project K[8] into a new one called ZOE... First steps will creating a new servo setup which supports Dynamixel Servos, and a new Conceptual design!!

Okay heres a bit of a tangent but if you follow my thinking for a bit youll see where Im coming from and hopefully going...
Rb550f's Jo Robosapien Project
I started working on this Robosapien project with making a new head from a 3d kids space projector. Fabricated face...
Redzone's 2Nd Inmoov Build
So I started my second Inmoov without a name yet. I havent given up on Gideon, my 1st Inmoov, I have learned a lot from...
That's correct!!
okay.to be able to use the eyes i need ?any pics about connecting the eyes?
@Mickey666Maus: Thanks for sharing your design. I've started the building process. I'm not good hacking designs so I'll follow your last design (OLED eyes).
Oleds: I've use the adafruit 128x64 is well supported both the oled driver API and high level libraries. There are 2 options I2C and SPI. I recommend SPI connection (faster) and I recommend adding a mini-controller to handle animations, and storing the bitmaps, and the low level computation. I've tried a few this is the one i recommend: https://www.adafruit.com/product/3800
Has a lot of memory to handle the drawing buffers and has a 2MB SPI flash can be used to store animation frames.I've a old ROS project where i used OLEDS. I wrote a lot of firmware code and a ROS node, I'll resurrect the project and I'll adapt the firmware to allow an integration with ARC, maybe I can make a hybrid version linux & windows /ARC.
I'll share the progress later.
ptp, I was asking about you, saying when were you going to show up here, lol, and here you are.
Nomad, nallycat said (PETG )use Weldon 3 ? what for?
are there fumes?
EzAng
@EzAng PETG by itself is completely odourless it is food safe and can be put into a dishwasher, it is heat resistant. if you need to join 2 printed pieces you use Weldon 3 it is a solvent joining method as PETG is an acrylic they use Weldon 3 to join sides on acrylic fish tanks and you can guess how strong that has to be. Weldon 3 is a solvent very thin and has a solvent smell like acetone but disipates when dry. you brush on both sides of parts to be joined and hold together you do not use much, too much will soften PETG and make it muchy. ABS uses acetone to join printed parts, same process. hope this helps you you should know ABS has a very strong smell when printing. I think you must not breath to much of these fumes. that is why I print mainly PETG. the solid color like white black are the best the transparent colors I find are way to fllexible.
nallycat which brand of PETG? I bought white...
Are there fumes while it is printing? need ventilation?
use hair spray?
Thanks nallycat
Ezang
no ventilation,remember keep the heat inside. here a link for the hairspray. there are hardly no fumes. hairspray
there are also other producks for sticking the part on the bed.
3dlac
and then you have the UHU sitcks withs i use.
Hey Nomad, until the servos arrive you can have fun with the head of ZOE! Let me know when you are getting the Oleds and your Pi Zero, and I will help you wiring...
Also @ptp is recommending an additional board for more speed and ARC integration, I will look into this so we can use it with ZOE in the future!
