Step 7: WiFi Arduino Shield (i.e. Light Shield 7) - Intro

The Light Shield 7 is an Arduino and Maple compatible shield which adds several featuers useful for a variety of applications, but also specifically for use with the Light Brick 5 which it is designed to be integrated with.
  1. High efficiency switching power supply to convert 24VDC to 7.5VDC for use by the Arduino or Maple board.
  2. 24VDC passthrough to a 5-pin header compatible with the Light Brick 5.
  3. 3.3VDC regulated voltage derived from Arduino/Maple power supplies for powering the Microchip MRF24WB0MB integrated WiFi Module.
  4. Open-source Firmware available for both Arduino and Maple based on the async_labs WiShield offering significant improvements to the stability of the UDP stack as well as integrating Open Sound Control (liblo) functionality for easily controlling any device over wifi.
  5. Passthrough connection from either the Arduino or the Maple PWM output pins to the inner three connectors on a 5-pin header along with 24VDC and GND. These pins can also be used as general IO, or for PWM output to other devices such as motor control systems.
How much would you say this cost you in total? <br>
I want to hear the answer to this one too. If it's relatively cheap, I will totally be making some of these.
Hi,<br><br>So I'm selling assembled boards with machined cases and such, but it's probably outside of the price range of most hobbyists. However, if you're game for actually going through the instructable and doing things like sourcing your own parts and finding an alternative way to do the case, you can do it for fairly cheap.<br><br>I'm selling bare boards for just that reason on the website, $15 and $10 for the LED board and the wifi board respectively. You can also find digikey bills of materials that you can upload to digikey to trivially get a complete parts list. There are only a handful of parts that you have to source from other suppliers (LEDs from philips, optics from philips, wifi module and antenna from microchip direct).<br><br>When I am building 20 of these fixtures, and I don't build the case or include labor costs for assembling anything, the cost is $87 for the LED board (including board, LEDs, and optics, by far the most expensive part), and if you didn't want optics you could drop the component cost by $12. The cases are expensive, so if you can do your own machining, or have access to your own waterjet, you can definitely do a lot better than the prices I was able to get for custom machining since I no longer have access to free machine shops =/<br><br>As for the wifi board, if you are willing to hack together a way to route the PWM signals up to the light, and also get a separate 24VDC supply for the LED board and power the arduino/maple/whatever via a separate supply (the arduino melts if you put on 24VDC, their onboard regulator can't handle linear regulation down by that amount), you can actually use the original WiShield which is only $60. I have no clue how he makes them for that cheap, but that's no reason not to take advantage. You'll find that if you make them yourself, you can source components for 20+ for around $54 including the board, which is practically the same as the cost of an assembled WiShield. Personally, I think that for this application it's better to use the Light Shield because honestly hacking together the connection for the PWM and dealing with buying two power supplies instead of one overcomes the cost difference and is more convenient.<br><br>In any case, if you have more money than time, you can also just buy assembled boards. I'm going to be putting up a hacker discount so that people who aren't doing professional lighting installations can get them for cheaper, but I do know that I probably won't be able to lower the cost on the light shield by much since my cost spreadsheet says that it costs me around $90 to make them. The LED board I would be willing to provide cheaper as a bit of a community service though.<br><br>They take me a great deal of time to put together, and I really want to put together a bit of an LED war chest so that I can do my *next* project without investing $12k of my own cash... but I expect to release a coupon for 25% off of the assembled LED boards so that people who want to play around with high power LEDs but don't need the rest of the support equipment can do it.<br><br>Feel free to shoot me an email at neltnerb@saikoled.com or join the announce mailing list if you want to be sure to get notice when I do that.<br><br>As for my next project, I want to take three of the ledengin 40W RGBW LEDs and incorporate them into my same case. It'll be a lot more expensive, but three times as bright! Heat sinking though... it's a tricky one for sure =)
thanks for the info. this may have to go on a wish list
Relative to some things, maybe. &nbsp; But I don't think these are priced within casual hobbyist range.<br> <br> <a href="http://saikoled.com/products/ ">Check for yourself</a>.<br> <br> They are very pretty, though. &nbsp;<a href="http://www.youtube.com/watch?v=dhozYnVArzQ">This video</a>'s just entrancing.
ah well a casual hobbyist is exactly what I am haha
Hihi,<br><br>I responded to the comment a bit higher. Not sure if you get a notification when I respond to other emails in a thread you commented on =)<br><br>Brian
Nice! I didn't get an automatic notification, so I do appreciate the heads up. Your reply was thorough and informative, and I would have regretted missing it.
This is really incredible. Using light to enhance sound is a huge interest of mine. I do the old 60s liquid light shows for different events with some self made lighting equipment as well the overhead and chemicals.
also there is very clearly a hookah in one of your videos on your website, might dis/encourage some customers but thought you should know its visible.
Best most innovative project I have ever seen!
Big title !
yea, you're right. I tried making it shorter =)<br><br>thanks!
