April Meetings

We had a great turn out in April. Thanks to all the people who came!

First we had the fine people from Ace Monster Toys speak about their hacker space.

Ace Monster Toys is located in Oakland and has been around for about a year now. They are the first East Bay hacker space and they have a bunch of cool equipment that members can use. There are lots of smart people there everyday to help with anything you want to do. Also there are ongoing collaborations including a book scanner so if you want to get into something bigger that is possible as well. AMT has a general meeting at 7:30pm Thursdays that is open to the public so go check them out!

Then Andrew demoed making a parametric shape Processing and outputting an STL file that you could print on a 3D printer.

 

Oooooh geometry

A parametric shape is a mathematical defined shape. Generating these shapes is much easier and quicker than using a 3D modeling program like Solid Works so it is a good place to start when you are getting into 3D printing.  To generate the shape we used the demo code from Local Guru which and the unlekker library  made by Marius Watz. This library can convert a shape made in Processing into an STL file. Marius was the first Artist in Residence at MakerBot Industries and made some really cool parametric shapes while he was there. With the STL file you can use Replicator G to process the STL file and control a 3D printer to make the part.

 

March Meetings

We had a great meeting in March. Eric Maundu gave a great over view of the chemistry and system used in aquaponics. Basically it consists of a fish tank and a growing bed. To keep the tank clean water is pumped to the bed where bacteria break down the fish waste and feed the plants. Then the water is pumped back into the tank and the cycle repeats itself. Eric explained how this flow matches what nature already does only on a much smaller scale. For more information on Eric’s projects go to Kijiji Grows

 

Eric Maundu talks about the aquaponics cycle at Tech Liminal

Then Rik Kretzinger demoed his Arduino automated unit. The cycle starts with a pump that fills the grow bed. The water level is detected by a media probe.  When the signal from the probe is big enough the Arduino shuts off the pump and then waits a set amount of time. Then it activates a gravity feed valve that empties the tank. When the media probe signals the tank is empty the Arduino waits a set amount of time and then starts the cycle over again. All of which is pretty neat :)

For more information see Rik’s page on the The Aquapanics Gardening Community.

Rik demos his aquaponics system at the Tech Shop

Then we did our soft circuits miniproject and people went home with some great LED bracelets. This project used conductive thread to connect a battery to a LED. When the bracelet was snapped together it would close the circuit and light up the LED.

Make:SF July Recap

This month we had a great turn out to see Because We Can speak and to make EL wire at Tech Liminal on July 6th and at The reMake Lounge on July 13th.

As always our members showed off their cool projects. At The Remake Lounge Steve showed his progress with his EEG controlled robot. He has now integrated a new headset from NeuroSky with the Mindstorm. His next step is getting to the raw EEG signals so he can do his own signal processing. Be sure to check out his website for all the details

Because We Can spoke about “Turning Pro: Becoming a Professional Maker” The ideas that stood out for me were “Good Ideas are Useless, Good Execution is Priceless” and “Fail Often, Fail Better”. They also were realistic about running a business saying that you will only spend 20% of your time working on the things you love to do and that you should not start your own business if you are in it for the money.

Then it was onto EL Wire with the kits coming from Cool Neon.

After choosing colors and some delicate soldering….

It lights up!

After that you can make anything light up including your hat!

We had a great time and we can wait to see you all in August!

Make:SF Aug 10th @ reMake Lounge

Hello Makers,

Well, I guess this month it is Fixers because we going to have a Sugru Hackquarium. If you don’t know what sugru is, it is a hand moldable silicone rubber that can stick pretty much anything together. It dries at room temperature and then it is water proof, basically heat proof, and strong. So search around and find all the things you want to fix, customize, or just make better and bring them to the meeting and get hacking. Check out their website to see all the cool stuff people have done with it.

This project will be free for members! and $10 for non-members.

Also we are starting a project to buy and build a MakerBot CupCake machine for all of you to use! Already, we have three people donating money towards the cost of the machine but we need more. So if you are interested helping out make this project happen come and talk to us at the August meeting or send us an email and we will explain what we are planning.

This fun-for-all-ages event starts at 6:30pm. Children under 14 need to be accompanied by an adult.

Where to go:
reMake Lounge
50 Post St Suite 9
Crocker Galleria (near Sutter St)
San Francisco , CA 94104

New to Make:SF? Here is what you can do:
- New to making? Come and explore with a fun mini-project.
- Have an idea? Come and we will help you get started making it.
- Making something? Come and demo it. Get feedback and network with the Makers.
- Come to see the speakers we bring in talk about their projects, tools you can use, etc.

Maker:SF meeting May 4th

Hello Makers!

Maker Faire is on the horizon and it is time to get your project ready. So this month we are having the Maker Faire Dress Rehearsal/ Happy Hour. If you are presenting at Maker Faire come with your projects and show them off. Practice your presentation and give your project a run through before the big day.

If you want to see some neat projects you can come and check them out without the crowds. Meet the Makers and see their projects close up. We will start at Tech Liminal at 7:30pm and then after the demos (around 8:30pm) we will head over to to Spicy Monkey Cafe for some food and fun. We are getting drink tickets so the cost will be $10 for members or $20 for non-members for the first round of drinks and appetizers.

Make:SF April 12th @ reMake Lounge

Hello Makers,

We had our monthly meeting at the reMake Lounge last week. We had some great demos and then played with Processing and Arduino to make the Temperature Clock.

First we had Chris who made the MUNI light

It polls the MUNI information for a stop you set and determines when you need to leave the house to reach that stop. It goes from blue to blinking red the closer the bus is to your stop. You can check out his website for more cool stuff

Then Andrew showed off a crank LED flashlight he found with way too many features including an neat adapter to charge an iPhone.

Finally we had Jeff show off his new project: the Minimalduino. It is a shield compatible Arduino with the minimum number of parts you need to make it work.

Check out his blog for more pictures of this project and for all the other cool stuff he has made. Also, if you are interested, you can download the Eagle files for the Minimalduino and make one yourself. Another cool thing he mentioned is that the Portland Dorkbot does a PCB order every month. They charge $5 per square inch and you get three copies of your design. It is a great way to get a few professional boards without paying a lot of money.

Then we went on to our Temperature Clock mini-project. Everyone was able to get it working and then had some fun playing around with the different displays. If you want to try this project yourself all the information is on the Make:SF wiki. Feel free to download the files, go through the tutorial, and make any changes you want.

See you all next month!
