PrintPi 01 at Milwaukee Makerspace

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.

Time Lapse Bot 3.5 (and 4.5?)

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!

DamCamp ReCap

DamCamp

DamCamp (aka BarCamp Beaver Dam) happened on Saturday, March 24th, 2012 and this is my review…

First off, I will shout out a big thanks to Jason Gullickson, his wife, Wayland Academy, the Beaver Dam Makerspace Project, and anyone else who helped organize the event and made it happen.

Wayland

The Venue
DamCamp was held at Wayland Academy, which is a coeducational college preparatory boarding and day school in Beaver Dam. The main room was an auditorium, which was full of seats, a stage, large screen, and projector. There were two other rooms we were going to use, but we really ended up just using one other room, the lab, where the 3D printers were set up. The venue was easy to get to, and there was plenty of free parking! :)

The People
This was the smallest BarCamp I had ever been to… and that isn’t a bad thing. I remember times in BarCampMilwaukee history when some people were very focused on the numbers, and personally, I prefer quality over quantity. If the right people are there, that’s better than more people being there.

I saw people I knew who I haven’t seen in a while, met some new people, and met people IRL that I’d only met online before. What more could you ask for?

Time Lapse Bot 3

My Junk
If you’ve been to a BarCamp with me, you know I tend to bring a lot of stuff. I’ve been known to bring a photo booth, cameras, tripods, audio recording gear, tables, 200 feet of extension cords, power strips, and on and on. This time I brought Time Lapse Bot, the Egg-Bot, Friday Night Drawbot, my still camera, and not much else. It only took me about 3 trips to load in! (And I found it quite refreshing.)

Friday Night Drawbot

The Sessions
After the opening and introductions we launched into the first session… which happened to be my session. I gave a quick talk about some art robots that I like, and my take on what an art robot is (and isn’t) and then did a demo of the Friday Night Drawbot and the Egg-Bot. (Slides are here.)

I did not keep track of all the sessions, but we did one on 3D printing (there were 3 RepRaps there) and one on creating hackerspaces/makerspaces, and one on making noise with electronics. I ended up getting a lot of good info from the 3D printing session, and I’m a bit more motivated to find the time to finish my RepRap build. (Less sleep is the obvious answer!)

In conclusion, I had a good time, and I learned things. It was a small event, but I don’t think that detracted from it at all. In fact, I wouldn’t mind seeing more smaller events. BarCampMilwaukee is big, and it’s awesome, but it’s also a lot of work, involving a lot of people. Perhaps both ends of the spectrum can co-exist.

If you haven’t been to a BarCamp event yet… why not!? Maybe you’re more into food than technology. Well, you should consider attending Madison Food Camp which is coming up April 7th, 2012! (Yes, I said “Food” not “FOO”, just to be clear.)

Milwaukee Makerspace Grand Opening (Time Lapse)

Time Lapse Bot did managed to make it out to the Grand Opening at the Milwaukee Makerspace, though he was somewhat neglected when up against Egg-Bot and Drawbot

Can’t all the robots just get along!?

Watching Ice Melt

This is a video about ice melting.

Yes, I’m totally serious, because as you probably know, I only make serious videos.

Actually, this video came about when we had the big snowstorm back on February 2nd, 2011. Everything was shut down, so the Doctor and I stayed home and did a whole lot of shoveling. We also played in the snow a bit, and she brought in these huge icicles I knocked off the house. We put them in the sink to melt, and as usual, I figured I should put Time Lapse Bot to use and record things. Little did I know it would take so long…

It took 27 hours for the ice to melt. It probably helps that our house is usually between 55 and 60 degrees. If you see any water splashing onto the icicles, it’s just due to the fact that I had to wash dishes at some point. Other than that, we were able to pretty much leave them undisturbed, though next time I’ll probably set things up in a tub in the basement.

Anyway, I hope you enjoy this video of ice melting… even though it took 27 hours to film it, you should be able to watch it all in about 20 seconds.
