Absolutely love it! Can't believe you got enough pressure out of those tiny pumps. Have to try it out for myself!

This is great! Do you think the same process would work for bootloading .uf2 files used in Adafruit's circuit python boards? I don't think Adafruit provides the .bin files or the source code. I'd love to make an Adafruit M0 express board in a smaller form factor.
DIY Adjustable Focal Length Fluid Lens
Love the idea! You should attach a pump to it and make an auto focus camera!
Yeah! It's a glass back. Expect results like the 1+ phone in the instructable.

That's great! I'd love to see some photos :D
Oh no! There is no analog clock! That's just photoshopped to illustrate how to read the clock :P

Glad you liked it!
Oh my God! This is amazing. Thank you so much for sharing!! I was surprised that I couldn't find any clocks like this online since it seems like such a straight-forward idea. You should really write a blog post about it!!Having an led in the middle is Genius by the way. I'll probably stay away from it, maybe do an edge light to show the outline instead.. but it's just an artistic choice on my part.
Oh I agree completely! It was an artistic choice I made, I've already ordered some veneer though :P
It's a sad truth that we makers often neglect everything except for 'the project' to the peril of health, wealth and relationships. It's good to maintain a balance and you should never have to justify yourself for that!
Thanks for the compliment!!
That's actually pretty smart! You should do that!!

I only meant to point out the losses in DC-DC conversion, which would be significant if, say, you took an off the shelf converter module-those things get hot!. But hey, if you're spinning your own board, nothing is stopping you! I'm sure you can convert 0.5-1.5V to 3.3V with >90% efficiency. And you might be able to get the last 10-20% juice from the battery when it goes below 1V. So there's a marginal gain in power there. But can decrease the power consumption further by moving to say an attiny instead of the Atmega328 and using the lowpower library cleverly. Go for it man! Looking forward to the results :D
If you want to power it off of a single AA battery, you'll need a DC-DC converter. That will decrease the efficiency quite a bit as well.. But here's the smallest GPS module I could find. Here's a small 5V step up module as well.
In case you are wondering about some other module as well, I think this will help:Any GPS that send data using serial connection (identified by Tx and Rx wires on PCB or the word 'baud' in the datasheet) will work. :)
Oh, I had no clue about the Almanac information being transmitted.. I hope you don't mind if I include this in the instructable. Thanks a bunch!
Yeah, but it's not super accurate.
The GPS itself draws about 50mA, so the bulk of the power consumption. You can do that by adding a switch between the Tx of GPS and Rx of the datalogger. But, since the power saving by doing that is minimal, I wouldn't advise it. Time to cold fix depends on a number of factors including -but not limited to- your speed, time and distance from last fix, cloud covert, how many satellites happen to be around.. I generally get a fix within 10-15 seconds.
OpenLog is based on arduino and the code is open source. I think it'd be quite easy to write a bit of code to start recording after a set interval. But, this project was aimed to be dead simple :)

My laptop's battery is not removable, and it acts as a great internal UPS.
That would be ideal, yeah. I don't know of such software for Macbooks though :/
Thanks! and I agree completely. Ideal would be a laptop power management level solution which lets you select what is the max percentage you want to charge you battery to. As far as I understand only lenovo thinkpads and few sony viao laptops have this option. I doubt it is even possible for many of the laptops out there. But I'm sure some hack like this would be possible for mac.
Yup, you're totally right. Fixed it in the circuit. I actually ended up using a FET with a built in protection diode.
