Skull Art Project Close Up
zhlédnutí 29Před 2 lety
This is a project inspired by my girlfriend, she came up with the initial concept and I put my own twist on it. At the moment it's powered from USB, but the next step is to have it battery powered for a cleaner look! At the moment the LED pattern is just the neopixel demo code, I plan on replacing that with something more final soon.

304 RGB LED Sphere Project
zhlédnutí 2KPřed 4 lety
Added spiral, rain, bouncing ball & fireworks animations. The Sphere consists of 16 slices with 19 WS2812 LED's per slice and uses a single atmega328 at 16mhz to control everything. The sphere is powered by a 2200mAh Li-PO battery & can be recharged through a USB port. A Teensy 3.2 "master" slice with an accelerometer is in the works and will be ready soon. Inspiration came from Nikolay Nikitin...

Robot Color Tracking
zhlédnutí 1,2KPřed 10 lety
This is a video of my arthropod robot using a "pixy camera" to detect and track objects of interest. Everything is being processed in real time; Sorry for the bad video, I will try to make a better one soon.
Superb!!!
Thw black sun Schwarze Sonne
very nice!
its like one of them jumping spiders........make it jump and attack now hahahaha
i miss mechatronics
When will you make the silent Nipkow clock? :)
its kinda cute!
Amazing, very lifelike vehaviour
That would be cool at a party
It looks so cool on the camera I think it's like that in reality also idk
Super is the best......👍👍👍🙏🙏🙏
Great demonstration: My only thought is that it looks to be a bit oversensetive (constantly making micro-adjustments to keep the tracked object in the center of vision). This could waste power and shorten battery life. My suggestion would be to increase the amount that the object can deviate from the center of vision. Maybe create a radius from the center that the tracked object should stay within, and if it goes out of bounds it adjusts to put it back in the center. That way it's making fewer adjustments, but when it does it's correcting completely.
u r great
Show
head tracking is an an absolute gem if you want it to look alive.
Thank you very much for your fast response.
Any chance of a detailed build?
Thats cool man
Any chance of a detailed build?
I do plan on putting everything up on instructables.com, at the moment I am playing with different MCU's. I started with an ATMEGA328 and quickly ran out of memory, then built a version that uses a Teensy 3.2 with lots of memory but no connectivity, so I just ordered an ESP32 since it has bluetooth & wifi.
I just put it up, sorry it's taken so long! www.instructables.com/RGB-LED-Sphere/
Hi! does your code still exist I'm using the the same lcd and arduino board like yours, can you give me some ideas 'bout it? ty
The code is at the bottom of this page: www.instructables.com/id/QR-Digital-Clock/
Very nice project i follow your instructions and i got the hexapod working but i cant download the pixy 2 camera sketch from your github i get an error pixy h no such file or directory what im doing wrong any help thank you
To program the nano with the PixyProgramHeightWidth code you will want to use Arduino IDE 1.0.6 and the Pixy library to compile & upload the code to the nano. My guess is that the pixy library is missing from your libraries folder, which is why your IDE cant find pixy.h. I did not write the Pixy library but should be easy to find with google, download it and load it into your IDE and then try to compile/upload. Let me know if you have any trouble.
Hi David i follow your instructions and it work i was able to download the program to the nano, now i should mention that im using a botboarduino from lynxmotion and im not sure if im hooking the wires up correctly because you using a mega i connected the nano to botboarduino nano vin to 5v ground to ground and tx to rx wich is pin 0 in botboarduino but i dont think the nano is transmitting to the botboarduino in the nano only the red power light is on do this sound right to you thank you
@@davidhend ok i made it compile and upload to the nano but there is no comunication w camera or mega
hi david sorry for asking to many questions but now im trying to use the arduino mega but when i compile i get this error'cRRcoxaPin'was not declaredin this scope any advise thanks in advance
hello David success everything works finally after some error and trial but i do have one question the pan and tilt mechanism for the pixy is the program already in the nano would it work if i get the brackets for it thanks
where on the hexapod did you place the MEGA and the Nano?
The Mega is underneath the ps2 receiver on top, the receiver had two red LEDs. The UNO was small enough to put in the body of the robot under the camera. Hopefully that's clear enough.
Do you mind if I use this video ?
Do you have any issues when using HS-422 for all joints?
I did have a little trouble, and the robot currently uses six HS-645MG and twelve HS-422's. At some point I will replace all of the 422's with 465's but you can get away with it for a while if money of tight like it was for me.
It is the best robot class recreated by nature!!!
What is the LCD model used here ?
Why my mobile phone cannot understand 1 meter by 1meter qr code when the code is "A"?
Mr. Henderson, thanks a lot for this guide and code! I managed to build my hexapod and control it with a ps controller, but when I turn on the tracking, arduino mega freezes after a few seconds. Any ideas?
Jeremy Gilbert Same as you, managed to get the output from pixy and nano, but Arduino just freezes. I changed the sampling time to sample every 50 ticks, it doesnt freeze now, but doesnt respond too
Jeremy Gilbert You deserve a medal, Im gonna try it out tomorrow!
By the way, did you change pixy height/width or any other code files?
Hey Jeremy, did you manage to get any results with forward and back movement?
Could you send me the code with the changes you made, please? Thanks
Hi, where did you buy this lcd display?
The LCD was a 2.8" TFT Touch Shield V. 1.0 from Seeed Studio. I believe I purchased this one as a Radio Shack special. Not sure if Seeed Studio still sells V. 1.0 on their site though.
Hello , is there any email i can reach you - I have a similar project for which i need ur help - i have a small budget allocated for it as well - Thx !!
hello again manage to compile code. now i connected arduino mega and ssc 32 usb and play station controller according to your instructions but servos wont move . is using usb type ssc 32 make a difference u think or is something else thank u
Sorry for the delayed response. That's really interesting, I believe the ssc-32 has an activity LED that lights up after each command is sent. Do you happen to see any activity on that LED?
hello do you think i can use a botboarduino to do this project
I would think so, however I have no experience with that board. Also the software will most likely be different but don't know the specifics. Since you already have the mega you could try writing a small program to talk to the SSC32 to move a single servo a set distance, it is really easy to do that. This would let you know if you have things wired correctly and the baud settings on the SSC32 match the mega. Good luck with your project and let me know if anything else comes up.
it looks lifelike very cool u think i can get the code info and assembly thanks
Thanks! You can find all that information at: www.instructables.com/id/Arduino-Mega-Hexapod/
thanks for the info
Hi David , im trying to get the code from github but having some problems im getting error and asking for ps2 library i will welcome any help thank you
Sorry, I meant to reply sooner but got busy and forgot. You will need to make sure to add the PS2X_lib library included in the GIT repository into your Arduino IDE. You will also want to read the readme that explains how to replace the HarwareSerial.cpp & HardwareSerial.h. Hopefully that makes sens to you.
thank u i will give it a try
Can we use L293D ic for the H-bridge and a audrino nano for control???
can it Show real Videos and stuff like this?
in theory yes, but it would be super lo-res. I never got that far with mine.
How can i use gcode ...u dont mansion this...need help
Use GRBL i. Arduino
At last I could understand how the nopkow disk works. Thanks!
I would love to have a discussion with you regarding this beautiful monster I love robotics and build and sell autonomous drones all around the country. I would love to pick your brain of course we would compensate you, please let me know Thanks.
I wonder how you can sleep at night
+_who_cares_ LOL : ) This project definitely stays at the office, it would be tough to pull off in the bedroom for sure!
On your page i was't able to access the pdf or code, and would this work with the inchworm model of the hexbugs??
+Jorge Marquez That is really wired that you are not able to access either, I just tired myself and didn't have any trouble. Hmm... If you cannot get the code/spreadsheet to pull up, send me your email address and I will send them to you. At any rate, I would think that the inchworms circuit board is similar enough that you could do the same.
+David Henderson my email is marquezjorge54@gmail.com thanks a lot!!!! I'm doing his for a school project.
I have just started and the Arduino development. I watched with interest your project via CZcams. I also, QR-Code on the Arduino platform to express it. I would like to receive the source..... Please help.
송명용 The source is available at the following URL: github.com/davidhend/QR-Code-Generator More information can be found here in case you are interested: www.instructables.com/id/QR-Digital-Clock/ Have fun & let me know if you have any other questions.
David Henderson Thank you...
does it walk though?
Mr.Henderson, would like to know if the code for pixy cam with integration with the arduino on a hexapod is available online, if you so, could you please direct me. Also would like to know if possible, the servo cable sleeves, their measures. Thank you
linkspyder The code for the project is available at the following URL: github.com/davidhend/Hexapod I would suggest looking at the readme file on that repository for a breakdown of what's what. The cable sleeving, is 1/4" expandable sleeving from Altex.com www.altex.com/14-Expandable-Sleeving-BSPSC140-P150861.aspx I cannot remember the exact sizes but the largest was right around 12"
David Henderson Thank you Mr.Henderson for your info. I'm trying to build something similar to yours; can u tell me if with this one you are also using a ubec 15A to power the system? what type of lipo are u using? thank you once again.
linkspyder So I am using two UBEC's; one for the servo controller & servos, the second powers the robot's MCU's and PS2 receiver. The reason they are separated is because the servo "noise" causes problems with the RF for the PS2 receiver. Both UBEC's are 8A but can handle bursts up to 15A. I got them from hobby king at the following: www.hobbyking.com/hobbyking/store/__6233__TURNIGY_8_15A_UBEC_for_Lipoly.html In regards to the batteries, for the servo's UBEC, I connect a 3S 11.1V 2200mAH Lipo battery; and a 2S 7.4V 1650mAH for the robots logic. Let me know if you have any other questions, I will do my best to answer them quickly.
David Henderson Thank you very much for the information and help. Still got one question :) for the ps2 controller/receiver can you tell me which version are you using? thank you
linkspyder I am using the V2 of the PS2 controller/receiver; which I got from robotshop.com. They also have V3 now; which I am almost 100% sure would be a drop in replacement for V2. I will leave that up to you.
Looking very good :) I'm still on the drawing board with my model, I was originally working on a Quadruped based purely on the costs saving of only animating 4 legs instead of 6. But having done some research I decided to put it on the back burner for now until I have a lot more experience and refocusing on a slow Hexapod build. I have done some crude table top load tests on some TowerPro micro servos (MG90, SG90 and the new SG92) and have been very disappointed with the results. Of the 3 types the SG92 was the strongest of the 3 and i am as confident as i can be these are genuine tower pro. The MG90 are almost certainly poor clones as they came from a Hong Kong source via eBay and barely function at all (I will never learn lol). Not sure about the SG90. They perform better than the MG90 but the gears strip long before the motor stalls. I will be up-scaling the model to use the standard size servo. Just need to make a decision on the servo to use.
gears strip before the motor stalls??? that sounds terrible! but the bigger the motors the more power they chew up, so it can be an unbelievable power bill running a stronger robot, all servos in parallel.
Have you made any more progress? Was curious to know what servos you decided to use. I was considering Towerpro over Hitec as they offer a lot more torque for the size and they cost a lot less too. Problem is finding an honest source as the market is flooded with cheep clones so im told :(
***** In order to facilitate walking, I used the parts from the quadruped to make a hexapod, plus extra ordered parts. I have also swapped to using a PS2 style remote control. The firmware is also different and allows for more control. In order to make the robot more interactive I added a "Pixy Cam" from charmed labs; I integrated it in such a way that you can train the robot to follow a color of your choice. Here is a video of the progress I have made so far: czcams.com/video/R6kvBNsAwWs/video.html To be honest I am not overly familiar with the Towerpro servo brand; and dont have any personal experience with them. I am quite impressed with the Hitec servos; I am still using 12 HS-422's and 6 HS-645MG's. Ideally you would want all HS-645MG's but the 422's work pretty darn well and really hold up to the abuse; haven't broke one yet. You could always order some the the towerpros and see how they work. I buy almost all my robot parts from robotshop.com, they have always been very reliable and easy to work with.
are you using HS-422 here?
I sure was, they were good enough to move around and test code; but weren't strong enough for the quadruped to walk.
David Henderson Time to order more servos.....
At the moment I don't have it documented on the Web; I do plan on it though, hopefully soon.
link to blog or more info?
This is really impressive. Have you seen the t8 spider? With that motion tracking it would be amazing. Can you make the robot pursue the object? I would love to see a video of that. T8 3D Printed Octoped Robot - Spider Salsa Rumba! Halloween 2013
Thanks you very much. I have seen the T8 and was very impressed with it; the look and feel of it is top notch. I love how thin and light weight it is, it would be fun platform to tinker with. That's funny you mentioned perusing the object because the same thought crossed my mind. I haven't tried to implement the perusing behavior but do have an approach in mind. When I do, I will be sure to put up a video.
David, i posted some proyect which i want to pay for.. in workana which is very similar to yours.. www.workana.com/p/proyecto-simil-qr-clock-ver-http-youtu-be-ehbq52iiycu i would like to contact you
