Same! I wanna see an open source split flap module (ideally a single digit that's expandable) and easily made with access to a 3D printer (or laser cutter, I guess). Maybe I'll have to design one someday...

Great 'ible with good info! Working on building a new charging system/battery packs for an ancient electric car, and very new to batteries in general, so I was glad to find this!

Thanks for the tip! That does indeed seem like a better way to do it. It's been a few years since I did this, and I've hopefully learned a bit more since then... (I remember seeing this comment earlier, but don't remember if I replied- So forgive either my late reply or double-reply! XD)

Looks great! Thanks for the idea for where to put the last sticker... (I got three)

Thanks! Then I'd have to figure out where to put it...

Awesome. Look absolutely hilarious!

Thanks!

Looks awesome!

Excellent! (Ok, I just watched the video and skimmed the instructable, but from what I did see, awesome work!) I just love it when people combine technology and nature to create art! Lovely video work too, I aspire to be that good someday. Best of luck as a finalist in the microcontroller contest!

Thank you! It always gives a person a warm fuzzy feeling to help others.

Nice! I love how these old alarms look but do hate that awful alarm noise- I once found a pretty cool looking mechanical one in the thrift store, decided against getting it, and have been kicking myself ever since...

Thanks for your concern about the food safety!I do have to disagree on some points. Taken from Wikipedia: "Thanks to its bio-compatibility and biodegradability, PLA has also found ample interest as a polymeric scaffold for drug delivery purposes." My research on other sites also indicated that PLA is generally considered food safe, though most filaments don't have FDA food safe ratings. If one wanted, there are PLA filaments with FDA food safe ratings available, for a little more than normal PLA, but we were rushed for time and decided that based on our research, normal PLA was fine.It is true that ABS is not food safe. However, we don't use nor recommend the use of ABS in any part of this design.As for TPU: I'll admit I didn't research this before the project- However, from a...

However, we don't use nor recommend the use of ABS in any part of this design.As for TPU: I'll admit I didn't research this before the project- However, from a bit of research right now, it looks like TPU is also generally considered safe. In it's use as the adapter for the tubing, it should never come in contact with the mouth, and it's highly unlikely that any particles of TPU would make their way into the user's mouth. It could also be eliminated from the design with a different sized tubing and a minor change to the mouthpiece, if someone wanted.As for any concerns about bacteria growing in the crevices- We recommend you run the mouthpiece through a dishwasher at least once a week, or sterilize it in boiling water, as stated in the Instructable and user manual. The PLA has been tempered, which makes it able to withstand high temperatures (And we did test this). The mouthpiece also has a built-in chamber to trap saliva and keep it from entering the silicon tubing.I assure you, we thought about food safety and toxicity and designed our device with that as a major factor. It is open source, so if you'd like to make it safer, by all means, please do!

Thanks!

Thanks! It was a pretty fun project, and hopefully others can benefit now too!

That would work as well, there's a Gamer who uses a device called a Quadstick that has this sort of function. For what we're doing, the varied intensity (Hard Sip, soft sip, soft puff, hard puff) is still easy enough to do (Though believe me, trying to get it to work without triggering soft sips/puffs on the rising edge of a hard sip/puff was pretty annoying!) If you wanted to add more actions or hotkeys/keyboard shortcuts though, that would be a great addition, and not hard at all to make!Thanks for the comment!

I don't have a 3D printer, so I can't recommend one, but I've used some, and have some information that may be useful to you.First of all, 3D printers are very easy to use. I haven't much experience with CNC, but I think anyone could use a 3D printer, so no worries there. Usually the process is to design a model using a CAD program, export it, "slice" it (cuts it into individual 2D layers for the print head to follow), then take the G-Code from the slicer program and tell the printer to print it. There are two main kinds of consumer printers, FFF (Fused filament fabrication) printers (Imagine a fine-tipped hot glue gun on a CNC machine, capable of printing in several different kinds of materials), and SLA (Stereolithography), which uses UV light to cure a resin. FFF is the mos...

FFF is the most common technology used, and should suit your needs just fine.Now onto your second question: If you haven't heard of lost PLA casting, it works pretty similar to what you're talking about. PLA is probably the most commonly used material in consumer FFF 3D printers. For best results, you might need to burn the PLA out first, but I'll bet someone's made a different material that works better for the technique you're talking about.Hope this clears some things up!

Thanks! Glad you liked it!

This is so cool! Makes me almost want to grow my hair out just so I can have it move around and help me do stuff XDVery awesome project!

This is cool! I wonder how many of these we'd need to keep mosquitoes out of our yard... Every summer we've got them all over at dusk, and though they wouldn't be carrying any diseases here, it's annoying to put up with them and their itchy bites. I suppose with larger emitters (such as the kind used in ultrasonic sensors) and higher voltages, it'd be more effective.On the topic of testing it, I wonder how hard it would be to create a controlled environment with mosquitoes living inside (IE, find a water source that's already breeding them, enclose it), then create two distinct portions, one with an ultrasonic sensor. You'd need some way to tell roughly how many are in each room, or at least tell when the density of mosquitoes increases/decreases. Then, you could wait for a significant ...

You'd need some way to tell roughly how many are in each room, or at least tell when the density of mosquitoes increases/decreases. Then, you could wait for a significant amount of them to breed, then turn the ultrasonic emitter on, and observe if there is a difference in the number of mosquitoes in the portion exposed to ultrasound. It still wouldn't be entirely scientific, but maybe you'd get more definite results.

I suppose you could use an ESP8266 module instead of the teensy, as it has similar specs ram/rom/speed wise, and is a lot cheaper- Plus, built in Wifi for connectivity, that way you could even make it into a smartwatch of types... I think power consumption is about the same as a teensy as well.

You're welcome! Tell me how it goes!Those look great, I'll add them to the 'ible.Best of luck!

That would work well- I suppose people could just buy 18650 cells too, since they're not expensive.

That's true- I've been toying with the idea of an RGB LED, or/and a piezo buzzer, plus a few other minor improvements. Actually, I'll just upload the Fritzing file to the GitHub, so you can do it if you want.Next time I redesign the board, I'll probably add those, plus breakouts for all the Arduino pins, to make it easier to add your own sensors/modules. When I get time, that is... It is on my to-do list!

Yeah, I'd rather use something other than a 9V too- Eventually want to use 2xAA batteries with a boost converter- Not much more efficient, but a lot cheaper XDBy all means do! Let me know if I can help at all in any way!

Hi, sorry it has been a while, instructables doesn't always email me when people comment!It would definitely be possible, with a little extra coding. In my library, I use PORTD, which is why it uses the D0 and D1 pins (Believe me, that was a headache to troubleshoot when I was trying to figure it out!)If you wanted, you could just use digitalWrite statements for each pin, but that would be less efficient (Though, the libary wastes a lot of time with the delays anyways)Or, I'll bet you could shift the bits over two spots, write the new value to the port without modifying the bits on D0 and D1- Since the SPO256 only needs 6 pins, not the 8 total on port D. I can't recall exactly off the top of my head, but if you look at the bitshift operators and others on the Arduino reference page, yo...

I did a lot of bitshifting and modifying partial registers without modifying the other bits in my SAA1099 project, and those were invaluable.I've been thinking for a while that I should update the library so as not to use up time while waiting for the delays, and to add some features and such. This is another good addition that I may add, when I get the free time... xDHope this helps! Let me know how it goes!

It's here, in case you haven't seen it (I haven't gotten the programming instructable done yet, but this one has all the building and soldering)https://www.instructables.com/id/How-to-Build-the-ProtoBot-a-100-Open-Source-Super-/

Yup! A little more expensive, but still pretty awesome for the tiny package/price! They can be found for about $9 with the encoders on eBay.

Thanks!

No problem, my pleasure! Thank you!

Thanks! I certainly plan to.

Perfect! XD

It looks super cool, but we need a video! ;)

This has to be one of the nicest minecraft-inspired projects I've seen- I like minecraft myself, but often it seems that the (mine)crafts people do are just... Not great XD This was not so! Well done!

I see no reason it couldn't be, s the Pro Mini is the same chip as the Uno, just in a different form.

Somehow I missed this comment, but yeah- It was 6$ at a thrift store a few years back. The bottom screen didn't work though, so that might explain why.

Just a note: You mixed up the names for the Arduino Nano and Micro in your parts picture tags.

Np! Thanks for commenting!

You're welcome! That's cool that it works much better. I've seen those sensors on eBay, never tried them. For my project, I need to make stuff as cheap as possible, thus why I made my own sensors rather than using pre-made ones.

Yup! That was a quick contest entry, but there's gonna be a fully fledged instructable soon (Been working on it as we speak ;P)(Also, thanks, I've been wondering if that still shows up on my page... Can't figure out how to delete it, and the contest entry thing had no formatting options so it's a mess... Oh well)

Thanks for the comment! I've been using these in a project for little educational robots, as line following and edge detection sensors. Out of curiosity, are they the E18-D80NK sensors? I've seen them online and they look like a good solution for more rugged larger applications.

Hahaha, yess- Wonder if anyone's made one of those yet... It's on my ideas list XD

Well, whatever the cause, glad my instructable caused a little mirth! XD
