Hey Lewis, how did your portable sound rig go?<div><br></div><div><br><br><div class="gmail_quote">On Fri, Jun 1, 2012 at 3:25 PM, Lee Sonko <span dir="ltr"><<a href="mailto:lee@lee.org" target="_blank">lee@lee.org</a>></span> wrote:<br>

<div><br></div><div>Short form:</div>
<div>Calculated a power budget. Strung together some used sealed lead acid batteries (look in the <a href="http://wiki.orbswarm.com/index.php?title=Suppliers" target="_blank">Suppliers page</a> for some cheap ones), charge them with a car charger. Profit!</div>

But it's sooo much easier to use an inverter, do that first!</div><div><br></div><div>If you've got too much money, use lithium batteries instead and the rig will be lighter. Sorry, I can't help with pricing out that system.</div>
<div><br></div><div>Tell me how it goes!</div><div><br></div><div><br><br><div class="gmail_quote"><div><div class="h5">On Fri, Jun 1, 2012 at 8:59 AM, Lewis Scaife <span dir="ltr"><<a href="mailto:lewis.scaife@gmail.com" target="_blank">lewis.scaife@gmail.com</a>></span> wrote:<br>

Thank you for existing. <div><br></div><div>i am attempting to put together gear for portable electronic music performance, probably set up on a bike trailer.</div>
<div>i will be using an arduino-based infrared gestural midi controller called Hollowbook - i've demoed it at Noisebridge a couple of times, you can check it out here: <a href="http://youtu.be/2OmqivEHpC8" target="_blank">http://youtu.be/2OmqivEHpC8</a></div>
<div><br></div><div>My electrical knowledge is limited. my goal is purchase a durable and lasting portable power system for the following items:<div><br></div><div>40w 19v DC 2.1A power adapter for Asus ul20a laptop
</div><div>9v AC 1A adapter for m-audio quattro</div><div>7.5w 9v DC 500mA adapter for hollowbook (power over usb from laptop is not an option)</div></div><div>POSSIBLY a boom-box style speaker system of modest volume but undetermined wattage...</div>
<div><br></div><div>i have been looking into portable power systems such as <a href="http://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Dautomotive&field-keywords=portable+power" target="_blank">these</a> found in a cursory Amazon search. i hoped to get some opinions from more experienced people as to what would be a good move. an option which i have considered is to purchase a separate battery powered amp to replace the speaker system if there would be too much load on a portable power supply otherwise. i would hope to be able to perform for at least 2 hours. i'm absolutely not looking for loudness - my goal is to fly below the "no amplified music" radar and play downtempo, instrumental chillout music with an awesome and unique midi controller. Valencia street has a lot of foot traffic at night and would be the perfect place to drum up a local fanbase.</div>
<div><br></div><div>Thank you sincerely for your time. i hope my post was in good taste and finds you all well.</div><div>best wishes</div><div><br></div><div>Lewis</div><div><br></div><div>you can hear my music at <a href="http://music.ratsofnym.com" target="_blank">http://music.ratsofnym.com</a> ... it's a spaghetti-western themed instrumental hip hop album... please let me know if you would like to own the album, i'd be happy to give you a free copy of either the mp3s or an antiquated compact disquette.</div>
