I have a keen interest in costumes and special effects. Being able to dabble in anything from latex and silicone casting, electronics, microcontrollers, and mechanical gives me a change to experiment in a lot of mediums. Long term hobby is etensive animatronics in my main costume that can be controlled using voice command.
  • 16 Channel Servo Tester With Arduino and 3D Printing

    Look at the circuitry for one of the existing buttons, and then choose a digital port that is not being used.Add code to check that port and when HIGH set the current 4 servo's to the desired locationI am not at my usual terminal but this is a start.

  • 16 Channel Servo Tester With Arduino and 3D Printing

    Something I would also add would be a function that will send back via serial comms a lost of all the servo positions , comma separated, and a line feed at the end.This can be activated by an additional switch called 'Dump'This way you could create an entire sequence of movements and possibly play them back.For real complexity you would then write a utility that you can add a extra column to the servo list which is the millseconds And as the system reads in each line it can check the old and required new position of the servo - and generate a set of micro steps between the two.Pretty soon you can have a very accurate and powerful servo automation system. Generally it's just getting the servo positions first that is the headache.

    Very easily - Try a complex animatronic head and you are recording sequences that you want to replay.

  • Simple Animatronic Mouth Using 3D Printing, Arduino and Python

    It be really nice if one could find a way to processing Phonemes and Viseme's in real time. This is key to a personal project of mine to get a wearable animatronic mask to 'mimic' mouth movements. A while back I found USpeech. I personally did not have much success with it but I will revisit it at some time.http://arjo129.github.io/uSpeech/https://codebender.cc/library/uspeech#uspeech.hhttp://tiriboy.blogspot.com/2014/08/voice-recognition-with-arduino.htmlhttps://hackaday.com/2013/12/31/an-arduino-with-better-speech-recognition-than-siri/

  • Hi.Thank you so much for such a great article. I have been trying to choose the best library to use for a project that will use either a SSD1351 or a ST7735 both being 128x128. The key to my project is to be able to dump a frame buffer in to the display and then recalculate the next frame buffer. Your modified TFT_eSPI looks like it will fulfil that purpose :)Again Many thanks :)

  • There is a way but you do need a more powerful laser (4-5w) What you do is spray a blank PCB with a Very thin layer of black paint, and then burn that off with the laser. The end results being the remaining paint is the resist.Also consider using the laser to make the solder masks out of mylar too.

  • Really Great Idea..About the only mod I could suggest is some kind of a heated hopper so one can recycle all of the failed prints etc. Although I am sure that making a 'chipper' would not be too difficult :)

  • marcwolf commented on janth's instructable 3D Scanner: FabScan Pi

    Really great idea. Having invested in a 3D printer but am still part of the 'mold by hand' a scaner would be most useful.. especially when working in organic shapes.Looking around my 'lab' I already have a RPi B and a RPi camera.Could one use the RPi B+ rather than purchase a new RPi 2.Also the Hat with built in Arduino looks to be great. Do you have an idea of when this might be available.I have seen oter designs that use 2 lasers and switch between them. Would this give better accuracy?Many thanksDave
