... start up a hacker space ...
FYI, There is a hacker space in Culver City. I haven't yet visited them, but they seem like a pretty active group.

Crash Space
10526 Venice Blvd, Culver City CA 90232

https://groups.google.com/forum/#!forum/crashspace


I visited Crash Space on the night they hosted an open house. I would go their every day except for the fact that it is that I don't drive (I find it odd as I am 19 years old) and they are located 15 miles away. I also have yet to visit Null Space Labs (http://032.la in Downtown LA. Until I have my license I have been buying in bulk at All Electronics in Van Nuys and working out of my garage. Also recently went to Hackaday Live (http://hackaday.com/2014/01/27/recap-hackadays-first-live-event/). Was anybody else on the forum there?
2  Using Arduino / Programming Questions / Re: Funkboxing FastSPI2 Library Problem on: November 10, 2013, 11:24:09 pm
The LEDs are being powered by a 5v 10A Switching Power Supply (http://www.adafruit.com/products/658), and the Arduino is being powered by a 9v 700mA power supply. The Data/Signal wire and Negative wire are connected to the Arduino from the LED Strip, and the 5v 10A goes to the LEDs positive and negative (different negative than ones connected to) wires.
3  Using Arduino / Programming Questions / Funkboxing FastSPI2 Library Problem on: November 10, 2013, 09:22:38 pm
I have this code (http://funkboxing.com/wordpress/?p=2073) running using the following:

• Adafruit NeoPixel Digital RGB LED Strip 144 (http://www.adafruit.com/products/1506)
• Arduino Uno Rev 3
• 2 of XBee 1mW Trace Antenna - Series 1 (https://www.sparkfun.com/products/11215)
• XBee Shield (https://www.sparkfun.com/products/10854)
• Xbee Explorer Dongle (https://www.sparkfun.com/products/9819)

I am running into a problem when I set the brightness to anything higher than around 50. Below 50 the LEDS light up fine, but anything above that mark the LEDs start to behave erratically. Instead of staying a solid pattern or color, the LEDS near the opposite side of where the Arduino and power are begin to flash bright random colors. However when less than half of the LEDs are lit everything runs fine. Is this a problem with power distribution (should I input power from both ends of the strip) or is this a software error? This only happens with this sketch and when using other sketches like the one from Adafruit work fine. Another thing to note is this sketch for some odd reason wont upload wirelessly over the XBee’s  but Adafruits sketch will.

Send that to http://engrish.com

Sent it.  smiley-lol

I got the Velleman K2633 Relay Card Kit from Fry's today. In the instructions I found out that it requires Raisin-Core Solder:

6  Using Arduino / LEDs and Multiplexing / Adafruit NeoPixel Digital RGB LED Strip (144 WS2812) Libraries on: September 23, 2013, 01:18:38 pm
I have been playing around with one of Adafruits 144 WS2812 LED Strips, and had a couple of things I wanted to do with it. Below is a list of the things I had in mind:

1. Expand on the Arduino NeoPixel Library from Adafruits GitHub (https://github.com/adafruit/Adafruit_NeoPixel) to have a audio source such as iTunes to adjust the brightness of the LEDs to "beat" according to the music that is playing.

2. Make a Python or java application to adjust the color visually (like the ThingM Sequencer software for use with the BlinkM I2C LED and Arduino)

If you have any info that could help me with the code and setup please post a reply. Thanks!

Mitomart, I shop at http://www.allelectronics.com/, located at 14928 Oxnard St. Van Nuys, CA 91411. I think making the shop more towards teaching would be more appealing, as most local stores sell products already. Your shop would be one of the few that have workshops and tools available.

Hey everyone I'm actually thinking about opening an store in Los Angeles for electronics hobbyists and would like to get your thoughts on it.

Here's what I have planned so far:

Location: San Fernando Valley (North Hollywood or somewhere nearby) and online.

Products: Arduinos (original and compatible as well as shields/accessories), Raspberry Pis, general electrical components (resistors, capacitors, wires, etc, etc, etc the list can go on forever lol), sensors, tools), ICs (Attiny, 555s, etc), and pretty much everything else you need to build something with electricity running through it.

Extras: I plan to have a few work stations with ready to go computers and soldering equipment where hackers can start building knowing they have access to any item they might need as well as friendly help. I have even thought about sponsoring and hosting meetup.com group meet ups.


Since a store like this will require a hefty investment, I'm asking around to see if Arduino enthusiasts in the Los Angeles area would prefer shopping at a local store rather than ordering online and having to pay for shipping/wait a few days. I have visited a few RadioShacks and although they carry Arduinos, they only offer about 1-5 shields and sensors (depending on the location). I also plan on having very competitive prices (cheaper than RadioShack, Fry's Electronics and even some online stores).

Any input would be greatly appreciated.

I have been seriously looking into renting a building or warehouse around North Hollywood, Sherman Oaks (where I live), or possibly Burbank. If anybody is interested in helping start up a hacker space near there or already has a space, please contact me. I would love to build individual workbenches for people and eventually invest in some 3D Printers and some large machinery (Laser Cutter, Drill Press, Milling and Routing Machines. Any one who is interested in helping out please message me or email me at Christopher@geekstreetsolutions.com.

Im going to go ahead and order parts for a circuit that is known to work. I feel that I am going to put more money into troubleshooting the circuit I have than buying a working kit.
10  Using Arduino / Project Guidance / Re: Help with Flash Trigger Circuit on: April 04, 2013, 01:24:30 pm
I have measured the voltage. Actually, the max voltage seems to vary on different flash units of the same type. It could just be the amount of time it is charged from the battery, or because the boards are old and used.
11  Using Arduino / Project Guidance / Re: Help with Flash Trigger Circuit on: April 04, 2013, 02:41:06 am
I was thinking the same thing. Removing any wire of the flash from the circuit triggers it. This is most likely due to the fact that connecting both wires fires the flash and me removing a flash pin is probably just a faulty connection. I'll try changing around the circuit and see if it works. Do you know of any similar circuits that would work. I know I could use an optoisolator but my local store All Electronics does not have the one I need.

I am having a problem with this circuit. I can detect noise and see the serial monitor respond, however the flash will only fire when I remove a wire and from the circuit. Does this possibly have with the fact that I am using a disposable camera flash unit. Any help is appreciated.

Thanks that library looks very useful!
15  Using Arduino / LEDs and Multiplexing / Re: LPD8806 Addressable LED Strip Library (32 LEDs) on: November 01, 2012, 05:56:54 pm
So even if I have a LPD8806 RGB LED Strip I can use the same code as the HL1606 RGB LED Strip?
