Today's thing is this:

Beginning of Clonedels at Ace Monster Toys

Today, we poured our first set of clonedel pieces for the upcoming set of Reprap Prusa 3D printers that we’re going to make at Ace Monster Toys. “Clonedel” is what people have been calling the Reprap printers where the pieces normally made from printed plastic are made from molds, instead. The printing of these parts on another printer, such as the makerbots we have at AMT, takes about 14 hours. Pouring them takes about 10 minutes plus pulling them from the molds and letting them cure.

You can see some of the first set pf poured parts below.

As it turns out, the molds had a few flaws in places, being either too rough or having some air bubbles, so we weren’t able to pour all the parts with the level of detail that we really want or without damage. We’re going to clean up some of the pieces and I’m going to print a few more on the makerbot in order to make a new mold for those pieces. Almost all of the larger pieces are fine and they take the longest to print so this is still an overall positive.

Over at Metrix: Createspace, where we acquired the molds, you can see that they’ve been working on building many of these as well:

The end result is a 3D printer that is much smaller and simpler than the makerbots we’ve been using in the space.

I’ve also had RAMPS boards made to act as the electronic brains for these in a fetching purple. I and others will be soldering components to these sometime in the next couple of weeks.

The end result of all of this is that we hope to go from having two makerbots in Ace Monster Toys and a couple more in the homes of members to, eventually, a dozen or more of these either in the space or in member homes.

We’ve also just ordered our 80 watt laser (with a four foot by three foot or more work area) from China for the space. This will give us the ability to laser cut acrylic and plywood sheets, opening up a whole range of work possibilities.

Solar Power Workshop this Saturday at 11:00 AM

The Solar Power Workshop that we wrote about before is happening this Saturday, April 23, at 11:00 AM at Ace Monster Toys. Myles will be doing a morning session and an afternoon. The first will focus on how solar systems work and the second will be people working to build their own wiring harness using Myles' panels. At the end of the day, people will have a working wiring setup and know what panels they will need to get for their needs.

Come and be empowered!

Python classes on temporary hold

Hey folks, sorry if you showed up last night and class wasn't on. I had some personal business to take care of and it seems I did not sufficiently inform everyone. So just to make sure everyone's well-informed ahead of time, I'm going to be on vacation for a little bit and the next two python classes are also on hold. Snake-wrangling resumes in the first week of May.
Apologies for the inconvenience, but might I suggest you take this time to check out DaveR's Arduino classes. He's not as cool as me of course (no one is), but he'll take care of your tech fix with his stack of USNoobie kits. See you all in May!

A Visit to the Internet Archive


The Internet Archive HQ

A number of us from Ace Monster Toys went to visit the Internet Archive on April 1, 2011. The creator of the DIY Book Scanner, Daniel Reetz, had come into town to meet with people there on, you guessed it, book scanning. As always, he came by Ace Monster Toys when he arrived to take a look at the progress on our own book scanner. He invited me, Myles, Robbie, and others to go with him to the Internet Archive to check out the book scanners that they use for their ongoing book digitizing efforts.

Solar Power Workshop Coming Up!

The class will be held on Saturday April 23rd, starting at 11am. No pre-registration is required. Payment for materials can be made with cash or preferably by paypal.

Oakland's new hackerspace, Ace Monster Toys, is offering a public class in building small solar power systems. You'll learn how to build anything from a solar powered bike light, to an emergency power charger, to taking your bedroom or field research site off the grid. The emphasis is on being safe, cheap and practical in a small footprint, where the whole system can be moved.

The class will be on Saturday April 23rd, broken into two sections: 11am to 1pm will cover how power systems are built, and 1pm - 4 will be a chance to use Ace Monster Toy's tools and experience to build your own system. The Theory class will cover:

  • A hands on walk through the parts of a solar power system, from battery to solar panel & all the parts that go between.
  • How to calculate the right size of solar panel and battery for your needs.
  • Where to shop for cheap & safe parts.
  • Useful electronic theory ( How understanding watt calculations will keep you from getting ripped off on ebay)
  • Legal and safety issues. ( Why you'll be spending a lot on fuses, and how to build something that could pass an electrical inspection)
  • How to secure your solar panels.

The afternoon workshop will allow anyone to assemble the wiring and fuses needed to make a system. We'll have a few batteries, charge controllers, inverters and solar panels for you to test out your system, and will help you to calculate how what type of battery and panel to buy. We'll have a few items for sale, but most people should order from the vendors. When the parts arrive at your house, you'll be able to quickly plug everything together and be confident it will work. Depending on attendee interest, we may schedule a follow up session to finish construction. Attendees will need to pay for parts used, most systems will use $15-40 in parts.

Ace Monster Toys is a Hackerspace in the SF Bay Area in Oakland (quite near Berkeley and Emeryville). The address 6050 Lowell, near Alcatraz and Sacramento. You can find driving instructions on our website at acemonstertoys.org.
