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
Training Theo Jansen's Mini BEEST
You should be proud that it's working as much as it is despite being a forty-year-old project! Kudos!
Glad you liked it!
Thanks again for sharing! I'd love to help out if you ever decide to convert to an Arduino setup :)
No, but you can have one. If only my parcels reached you by post.
That's actually pretty smart! You should do that!!
Thanks for the compliment!!

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.
I'm not a 100% sure but I don't think it captures speed directly. You'd have to back calculate if from the time stamp and positions. I hope you do it though! It's a fun use case.
Yeah, but it's not super accurate.
It's not possible to tell if the GPS has a fix without looking at the data in the SD card after the recording is over :( The long time lag only happens when you power on a brand new GPS module because it needs to process a lot of data to identify it's location. The lag will also be there if you move to a different part of the planet. But, changing batteries is the same as powering on and off. No substantial lag.
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 :)
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.

That would be ideal, yeah. I don't know of such software for Macbooks though :/
My laptop's battery is not removable, and it acts as a great internal UPS.
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.
