printpi01-browser

It’s hard to believe I’ve been working on “Time Lapse Bot” for almost 10 years… I mean, you’d think I’d be further along by now! ;)

But seriously folks, the Time Lapse Bot project(s) got much better once the Raspberry Pi camera module came along. It allowed for a small, low-cost, portable camera device with great capabilities. I’ve been using a version to monitor my printer at home for quite a while now, and I turned my old PowerBook version into the Milwaukee Makerspace Webcam long ago, but in recent times it’s seen the most use to… monitor prints at the space.

So Mark, our 3D Printing Area Champion, asked about building some Pi camera rigs for print monitoring. So I did. I haven’t really built a proper enclosure, or made it very adjustable, but so far it works.

Basically, it captures a photo every minute, which you can see by connecting to the Pi with a web browser while on the network at the space. If you are not at the space, you can visit a web page that will show a new image every five minutes. (There’s a script that does an SCP of the file to a web server.) The other fun thing it does is compile all of yesterday’s images into a time lapse video you can download. Oh yeah, you can browser through old images and videos on the Pi when on the network, though they get deleted after X number of days to save space on the inserted thumb drive.

Some scrap wood gets it just about at the right height to see the print bed. (Well, we wedged it up a bit… new version coming soon!) I’ve also got a second one in the works, along with a few enhancements I won’t reveal quite yet.

Since there’s no screen on the Pi you need to pull up a browser on a device and check that it’s pointing where you want it pointing. I had a screen working with one of these and then one day it just decided to never work again. Annoying, so that means no screen for now.

And yes, I really do love the Raspberry Pi.

MMS WebCam

It’s been way too long since I posted anything about the Time Lapse Bot project. Here’s some good background info, if needed.

Time Lapse Bot 3, which I haven’t written about since 2011 (or maybe 2012) has seen a few upgrades. Don’t worry, it’s still running an ancient PowerBook G4 (how, I don’t even know) but we long ago upgraded to a Logitech C910 USB camera. We then added a long gooseneck to allow for easy adjust-ability. And finally, it’s also known as the Milwaukee Makerspace Webcam, and it published views of Milwaukee Makerspace at http://mkemake.us/webcam

But really, Time Lapse Bot 3 hasn’t changed very much in the past few years… probably because I’ve been working on Time Lapse Bot 4, which uses a Raspberry Pi.

tlbot4

Time Lapse Bot 4.01 made an appearance at Maker Faire Milwaukee in 2016, using a completely hacked together frame on one of my old rolling chair bases, and it worked for the weekend, but I’ve got plans… I’ve got plans.

I’ve made a lot of progress with software, and picamera is something I highly recommend! I’ve also got TLBot4 automagically uploading to a server, just like the Milwaukee Makerspace Webcam (running EvoCam, which may be dead now, as the web site of the developer has gone AWOL) and it’s also doing the daily videos compiled from the still images. I’m 90% happy with the software… I mean, the last 10% is the hardest, right?

I’m also working on a new physical build of Time Lapse Bot 4, which will feature many mounting solutions, and an interchangeable wide angle lens for capturing crowds.

Hopefully I can get TLBot 4 up and running for an event in the next few months, but in the meantime, I’ll be testing it in my workshop. (And hey, it’s offline now, so what the heck!?)

Also, I used the knowledge and experience I’ve gained (especially from picamera) to create part of a museum exhibit that has been running trouble-free (knock on HDPE!) since November. Huzzah!

Here’s my first video: BarCampMilwaukee: Time Lapse. Actually it was a collaboration with Jerry, who set up a webcam while he was there…

Thanks Jerry! Hope the drive back to Iowa wasn’t too rough…
