Lots of new toys to play with this fourth of july weekend! Come by Saturday at 1pm for the openhack for new members or Sunday afternoon.
You really should use a different password for your different accounts. If you haven’t done so because that would truly suck, try this site. https://www.passwordcard.org/en
It generates a wallet-sized card of an 8×29 grid of characters using a pseudo random character generator (http://www.passwordcard.org/algorithm.html). No record is kept of your card. You will need the 64bit number to regenerate you card should you lose it. He also provides the source code to regenerate your own card. Each row is of a unique color, each column is of a unique symbol. The idea is that you print out the wallet-sized card and remember where in the grid your passwords are. You can choose to use each row as a password, each column, the last 8 characters of a row, diagonally, backwards, its all up to you. Pretty neat idea i think.
The OpenHack is when we welcome all non-members to come join in the fun. Here’s what what got in store this week at the openhack. If you have something you want to work on or discuss, reply to this post or just come down to the shop during the OpenHack.
Very loose agenda for Saturday June 18, 2011
Scriptblocks video game development, http://scriptblocks.blogspot.com
Ongoing saga of the Prusa 3D printer
PCB design/pricing for the knight-rider soldering class
Wall density heat maps
Possibly a Luminaria 2012 interactive exhibit discussion
This weekend is Free RPG day at participating retail stores. From the official site, freerpgday.com, only Dragon’s Lair on Fred Rd and Medical is participating. Grab something from there and we’ll play a game.
Also, you might want to check out San Antonio’s Power of Ten site for suggesting improvements to Downtown. Most of the ideas so far seem to revolve around creating parks and planting trees (boring!) I’d like to see downtown be more of an active place rather than passive. Parks are fine but baseball parks are better. Trees are fine but community gardens are better. Just my two cents. Anyways, take a look and add your own ideas. http://www.pps.org/placemap/sanantonio/
Is anyone interested in sharing their skills/knowledge by offering a class at 10bitworks? If you’re interested in furthering your own skills by teaching and possibly having a small source of income on the side, read on.
I haven’t figured out the details and need feedback from you to help me do so. Here’s what I’m thinking so far:
1) You don’t have to be a member to teach a class but the class must be approved first.
2) Don’t feel like the class must revolve around electronics or software. A hackerspace is all about the DIY culture. For example, Houston’s hackerspace, Tx/Rx Labs, has an amazing class offering including bike repair, wilderness skills and first aid, bioinformatics, web site design, artistic techniques and materials, and welding in addition to their electronics offerings. The austin hackerspace, ATX, offers arduino and ham radio classes.
3) A wiki page can be created so we can keep track of the list of classes offered and relevant details. If a class similar to what you want to teach is already listed consider helping out with that class or come up with another class to teach.
4) Charging a fee is optional. The idea is to charge the students, not 10bitworks :) 10BitWorks won’t charge you for the space, we want to encourage classes being taught for as affordable as possible. If you decide to charge a fee I’d recommend a discount to your fellow 10bitworks members but just enough to cover your cost per student. For example, if the class you teach requires $5 worth of material per student then charge $7 for members and $10 for anyone else. That’s just an example. You can charge whatever you want. But make sure its worth it or else no one might attend.
5) The class can be regularly held, irregularly held, or be a one time deal. Its up to you. Try to not schedule classes at the same time. This will ensure that there is space for those not attending the class and allow students to take multiple classes. The class can be a series but be prepared to plan out your classes.
6) Currently, there is no partitioning wall in the shop. Its an open 1300sqft space. If we really, really need to we could hang up curtains or something.
Those are my thoughts so far as a starting point.
If you’re interested in talking about this further, reply to this thread and let’s get started!
Title: aquaponics workshop presented by thehumanpath.com
Location: 281 at Cibolo creek (north bexar county line)
RSVP: Meetup.com RSVP Link
Description: The Human Path is a primitive living skills school headed by Sam Coffman right here in San Antonio. His classes are very much hands-on experiences. The cost of the class is $90. You will learn how to build a complete food system from scratch that can feed a family of four. You will also walk away with a hard copy of the latest manual on this system, plus a siphon for your dump barrel. The cost of the class includes an always delicious lunch.
Dress in work clothes and bring gloves, cup for water and or coffee, notebook and pen or pencil. You will be sawing, drilling and doing plumbing, filling the grow beds with gravel and planting plants.
Start Time: 08:00
Date: 2011-06-18
Title: KARS ham radio Field Day
Location: boerne, tx
Link out: Click here
Description: Every year the ARRL organizes a nation wide two day event for ham radio emergency preparedness called Field Day. It is a free and public demonstration of the capabilities of ham radio in infrastruture limited scenarios. There are a couple events in and around San Antoino and we have been formally invited to an event in Boerne by the Kendell Amatuer Radio club.
They will demonstrate operating their stations using solar, wind, and other off-the-grid power sources. they will even have a station setup to get you on the air eveen if you don’t have a license! This a fun event and competion to make as many over the air contacts as possible in a disaster simulated emergency.
Let us know if are interested in carpooling.
Start Date: 2011-06-25
End Date: 2011-06-26
Greg finished his KITT kit today. We are getting great feedback on these kits for the beginner’s soldering class. Thank you!
Feedback so far:
1) Pre-solder IC sockets so that students can handle the ICs while minimizing solder points. 2) LED placement: side by side and level looks amazing. Even though the circuit does not use any real fading there is a nice fade effect if they are side by side. 3) Leave room to bend LEDs at right-angle so that board can be placed flat in the hood of a toy car 4) Explain circuit as you go along: Solder 555 timer and then connect a single LED to it to demonstrate its function (blinky). Then solder decade counter, the first four diodes, and all six LEDs to show LEDs sweep one way. Then finish off the last four diodes to show sweep back and forth. 5) helpful to show circuit printed on board like in the Elenco kits and woudn’t mind if board were bigger than needed to reduce eye strain and beginner mistakes
Greg and Nick have so far tried their hand at laying out the project on off the shelf PCBs, both from radioshack. Greg used the $2 2"x3" PCB with DIP traces. Nick used one-half of the dual-pcb perf boads, also $2. Both boards require too many soldering points for a beginner's class. We'll definitely need to print our own PCBs. Below, watch Nick's completed project. Soldered side by side the LED back and forth effect is MUCH cooler than that which you saw in my previous breadboard video. If anyone has any leads or tips for custom printed PCBs, please don't hesitate to let us know. Also, if anyone wants to put one together let me know. I'll give you one on the condition that you provide feedback in terms of soldering difficulty and satisfaction with finished result. Oh, and $2 :)
