Hi Castvee, thanks for liking the One Transistor Flipflop, https://hackaday.io/project/112126-one-transistor-flipflop !
Are you sure? yes | no
Hey, thanks for the like for #Arduino Blocks for MIDI Controllers
Thanks for your interest about #Smart remote for robot Pablo , cool !
I also want to thank you for the like of my #Cardboard Relay - Uglytech is getting better project :-)
Thanks for your like to my project https://hackaday.io/project/86962-lawnmower-robot
Thanks for liking my Atmega328P Target and EasyFET projects :)
Thanks for the likes as well! Gotta hand it you that's a wild fix! I love it!
It's that time again! Thankyah, sir, for the skull, and good luck this year!
Hi thanks for liking my project Wheeled Walker Hybrid Bot!.
Thanks for liking #Digibone buddy!
Thank you for the idea! :-)
I can't wait to see and hear it!
I've already got a vision in my head now. Can't wait t out something together!
Going to set up a prototyping board soon and get started on software.
Thanks for liking my project bro!!

Have not heard from you for a while, glad to see you here and thanks for the like on my project!
Good morning and thank you for the like for my Cardboard Computer project :-)
Well deserved....One who can build a computer on cardboard can accomplish anything....Good luck!
Howdy Castvee8. Thanks for the skulls, and for the project-suggestion re: iterative-Motion! Good luck with the contest!
thanks for the like on my erector set project, I'm actually looking at it right now lol, I have it at work so people can see what home 3d printers can do. Thanks for your support!
Thank you so much for the like :) I appreciate that!
Us 3D printed project folks gotta stick together!
Yes we do, although my parts are not quite as complex as some of yours, but they are getting better :)
Hi, I'd like to ask a question about your work.
I notice that some of your CNCs have quite complex kinematics. I am (trying) to build an unusual machine that also has complex kinematics here - https://hackaday.io/project/18186-arc-delta-3d-pcb-drill-and-other-failures
I am wondering how your doing the kinematics. I see one project seems to be running on a Arduino Uno and others seem to have custom hardware.
Do you have a software platform or abstraction that you work with?
I tried to use an Aduino MEGA (8-bitter) but I am too rusty with my geometry math to break it all down to integer math for an 8-nitter. Now I am thinking of using a STM32 or something like that.
Interesting thought-points from this... Say you had an arm with two joints (one at the base and one elbow) and want to move the "hand" between two points... you don't necessarily have to calculate the angles of each motor along that path, one could just apply a little power to both motors (in the general direction), then measure the displacement, and if it's too far in one direction, relative to the other, slow that motor a bit, then repeat. Pretty simple loop with basically no inverse-geometry necessary. Hmmm! (Is that Euler's method?)
Thanks for the reply.
It now sounds like my best approach will be to start with a 32-bitter, probably an Arduino Due because I am already using a RAMPS board, and then work my way back to an 8-bitter when I have nutted out all the other problems. I will see if I can solve the problem with RAMPS being 5Volts and the Due being 3.3 Volts or just build something with a 5Volt 32 bitter in a MEGA form factor.
Thanks for another like Mark!
Thank you for your interest in the engine monitor project.
Thanks for the skull. Cool projects.
