Concept, design, and engineering / 3d printed foot
« on: December 02, 2018, 01:57:45 AM »
Hey guys, I'm experimenting with 3d printing and i thought that it would be a nice idea to make some custom 3d printed foots and attachments.

I designed this one yesterday, it is just a copy of the metal one.







Right now it's not working really well and I'm trying to figure out why it's making my stitches shorter than with the metal one.

I think that this could be a very interesting field where to make researches.

Let me know what do you think.

Thanks,
Ale

Hi guys,
I disappeared for a while and now you have to read again my poor English.

I went back studying programming and electronic and I worked a lot with the IOT (Internet Of Things).

I had back pain and I decided to build a smart back panel that could help me remembering me to don't stay too much sitting with a wrong position and to don't have sitting session longer than a certain time.

I'm happy to show you the project that I've been working on in the last year: smileBack.

I decided to release it as Open Source / Open Hardware so everyone can build it. I'm doing all the video tutorials and releasing all the schematics.

This means that you can build and sell it! Or make a better version of it. Or help me developing a new model.

It's very cheap to build and Im doing researches to make the construction less expensive and time consuming.

Im exploring 3d printing and laser cutting and I want to make it really easy and fast to build.

Right now the price in Europe is around 15/20 but it requires some effort to be built.

I presented this back panel at the Maker Faire in Rome, the biggest faire in Europe about making and new technologies. It was the last month and now I have just finished the first tutorial about the physical pressure sensors.

The next one will be about the back panel and youll need a sewing machine for it.

Right, one of our heavy and bulky machines. (I miss so much sewing)

This is the first video tutorial about the back panel, soon I'll do all the others.


I hope to be clear enough, I know that I did many errors. (I was pretty nervous talking on camera with 1000w of light in my eyes).

If you have any advice is welcome.

Things that we did:
    The back panel with eight pressure sensors
    The code to run it
    The basic electronic circuit
    Bluetooth connection
    Android application (Its very nice)


Thing That we are doing:

    Sensors calibration and researches for a new kind of sensor
    Implementation of Wi-Fi
    Managing big moles of data
    Working on website statistics
    Working on the new code for the back panel.
    Designing and modelling the website
    New design with 3d printing and laser cutting
    Cad drawing of the PCB
   

Thing where we need help:

    Testing
    Advises
    Collaboration


There is also a website called smileback.cloud that is under construction, soon you could find all the information and see your sitting habits (If you have a backpanel)

TL;DR  I developed with my team a smart back panel that helps you to dont have back pain and we are releasing it for free. Is easy and cheap and you can also produce and sell it. It has Wi-Fi, Bluetooth and statistics. It doesnt make coffee but you can help us to make it possible.

Thanks

thumb up for this project. Is something that I was also thinking to do, I talked a lot of times with Fouinard about it.

I was thinking to use bluetooth instead of wifi or usb but once that the machine is done is easy to adjust it. My biggest problem was to create the support for the blade, now I have the 3d printer and this would be easier.

If you need help you can ask for coding and some electronic, I felt in love for Arduino some time ago and I pretty good with it.

I can assure you that a an Arduino Uno r3 has enough ram to do everything this machine needs to do. You can't believe how incredible are 2kb of ram if well used.

Are you going to release it open source / hardware?

currently i am using an Atmega8 chip for the blade temperature control (will scale down once i decide which thermocouple to use, Thinking ATtiny85 or ATtiny10 if i can minimize the circuit a little more) and an Atmega328P chip as the main brain, i think that chip is what is in the arduino uno and nano, i won't be using the arduino ide as it has a few limitations that using the Atmel IDE doesn't.

still unsure if i will have the time to add wifi but personally i think wifi would be more beneficial than Bluetooth as it
 means a computer could also have software to interact

Depending on how my test results i may release it but will happily help you out if you need a hand on any design elements, my university has talked about possibly patenting a element of the system so unfortunately i wouldn't be allowed to give out that element as they will own the patent (god damn university),

thanks for the input @less@ndro

Im out of the shop this week, but as I recall the hold down bar is located between the blade and the drive roller.
One more thing to consider is an auto retract function that pulls the webbing back, away from the heat of the blade after a batch cut. This keeps the webbing from melting while parked between batches.

Thanks man, and does the blade sit in the down position after a batch? would love to have a chat if you had the time

yes, atmega 328p is the same of Arduino Uno. One of them should be enough for all the machine. I'm developing a project that has much more calculations involved and the Arduino is working well.

Can I ask you which limitations did you find withe the Arduino IDE? I know that the Atmel IDE is more powerful but actually I had never found any limitation with the Arduino IDE.

thanks.

Thank you. I hope that soon I could bind with an attachment.

Packs and bags / Kite style backpack tutorial and schematic
« on: October 23, 2018, 12:15:21 AM »
Hello guys,
I'm not sewing a lot lately, I'm having a lot of stuff to do so most of the time I just watch what you guys are doing.
I'm experimenting with video editing and I did a little video tutorial about how to do a kite style backpack, in the description there is the link to my website where you can find the schematic.


Sorry for my english, I hope you can enjoy the video anyway.

If you have suggestion please feel free to tell me because I want to improve the quality of my videos and post more stuff related to fabric making and new technologies.

Thank you

The next time you could think to put the webbing in this way so you have less thickness and it's coolest. (thanks to jma)



I have a question. Why did you put the mesh on top of the backpanel where no contact is involved?

ps. Congratulation for the book, which kind of book is it?

nice job, I like the backpanel! I see that you really likes backpacks!

Hi guys, I made a little tutorial, I know it's not perfect but I hope it can help someone. If you have any suggestions please tell me because I want to make others tutorial. Thank you.

Materials science / Sew carbon fiber plate
« on: March 03, 2018, 01:56:46 AM »
Good morning guys,
I'm searching for a very light material to use it instead of hdpe for a backpanel. I found some panels of carbon fiber and the thickness is around 2mm. I need to sew the 2" webbing to insert the aluminum bar, do you think it's possible or the carbon fiber panel is to hard for normal needles?
Anyone has ever tried?
I don't think  I can glue it, what do you think?
Another option is to use fiberglass that I know it's cheaper and more flexible (but also heavier) but I still don't know if the sewing machine can handle it.
Thank you guys and have a wonderful time sewing!

Hello Thomas, i really liked your handmade backpack, i'm glad that you are here and i'm curious what's happening now that you have a sewing machine!
