Let me help you #MakeYourOwnBits

Thanks @chris101! It works now. :slight_smile: @alexpikkert, I’ll give that instructable a read. :smile: Something to think about for attempt 2 is how to solder bitsnaps if the circuit is all topside… :interrobang:

Hi @JackANDJude,
great success !

Attempt 2:
Put the bitsnaps on upside down? (when the smd parts are not sticking out too much…)
Soldering the bitsnaps when the circuit is all topside needs a double layer pcb I think…
I stumbled upon yet another instructable:


maybe there is something in this story you can use. happy reading… :grinning:

Hi, I am new to the forum and to LittleBits. I want to design some bits, but it is not clear to me how to find out if the bit I am thinking of is already being developed by another person. I went to the bitlab area and I see only 3 bits that were voted to become bits and a few going to production, and the area labeled as “dreaming” about a bit did not seem to represent what work is likely being done in the community. So is it possible tell if the bit I want to develop is already registered, please?
Thanks kindly for your reply.

I suggest starting another forum post with your idea and mentioning some of the ppl on this thread. Someone will jump in and help out. But we need the detail on that bit. You’ll notice in the bitlab that some duplicates exist like the joystick and Reed switches. The lb team is supposed to be working on a new bitlab for us to submit too.

I would like to connect an sd-card to store data locally. I would normally stream it off a cloudbit but I do not always have internet connection.

I’d think your best bet is the arduini bit and wiring an SD card breakout to it. I have both of those but haven’t had this use case. I’ll take a look and get back to you here. But I’d think it wouldn’t be to hard.

How about using the cloudbit and IFTTT to log to a Google sheet?

The problem with cloudbit is that it requires internet connection. I can’t count on that. So like to dump data locally. If you do something with arduino and sd-card, like to hear about it.

Hello Bit Community!

I am working on a school project where we have to make an assistive device for someone in our community using littleBits pieces. My partner and I would like to make some sort of shoe tying robot. We are just reaching out to see if anyone has made something of this sort, bits we might need, or help on how to set this project up. Any feedback would be greatly appreciated!

Thanks in advance

Welcome, @DSween007! I’ve done a little work with robots in LittleBits, but nothing with the articulation or fine-grained control you’ll need for this. Here are a few things that come to mind:

  1. What assumptions can we make about starting and ending conditions? Do you need to detect the laces and pick them up? Can you assume someone will put them into whatever manipulators your project has? Does it have to double-knot? Does it release automatically at the end, or does the user participate in removing the robot from the laces?

  2. This project for a rock, paper, scissors-playing robotic hand probably covers a lot of the ground you need as far as the right bits and how to combine them:

https://classroom.littlebits.com/projects/animatronic-hand

I don’t know how much grip strength that hand can provide, nor whether it even makes sense to emulate a full hand — maybe it would be easier to conceptualize like knitting? I do expect that you’d need something this insofar as you would need servo motors to turn things, an Arduino or CodeBit to sequence the instructions to the motors, and possibly a bend sensor to test tension in the laces. (I have no experience with the bend sensor, just guessing there.) You’ll need something like Meccano or Erector to fabricate the mechanicals, since there aren’t really LittleBits parts for those.

You might find some further inspiration from the Base Inventor Kit, which includes a design for a claw to grasp things. Hope this helps!

Hi Philip!

I have a Volca Modular that I would love to send pitch and CV into from Ableton. I have CV tools, and a midi controller…

What do I need bare bones?

Do you have a DC coupled audio interface?
You need that to be able to use CV tools.
The usb i/o bit (w27) is a DC coupled interface, that is easiest, but it is only 1 channel in/out, so it probably won’t fit your needs
If you use another interface you need to make sure the output stays within 0…5v.
I recommend the Motu interfaces.

Alternatively if you are not using the CV tools in Ableton you could use the midi bit, which functions as a usb midi to gate+cv interface.
Other midi to cv solutions are also possible, but you need to keep the voltage range into account.

It is also not that hard to setup the arduino bit as usb serial to gate/cv signals and to wrap this in a max for live device. But… the cv might not be accurate/stable enough for pitch information.
I hope this helps
