| Hey there, it's finished! I recreated a homemade ringlight based on your ringlight 2.1 schematic, although I made a few small changes. I put the converter housing on the hotshoe and use an RCA jack to connect the LED housing to the converter. What this does is make it easy for me to create additional housings that use the 2.1 converter. Since for my first pass (and testing) I only used 40 LED's, I knew this wouldnt be my last one... but this way I can make one with 3-rows of LED's, or one using UV LED's, and I can interchange them quickly into the 2.1 converter. I wanted to thank you for your fantastic schematics and your helpful response to my earlier email. Thanks ! See the attached website for the picture ________ Fuzzcraft's reply: Looks absolutely great! Smart move on the the universal power supply. Be careful as to not unplug the LED ring while the converter is switched on! The output capacitor for the step-up converter will be damaged, as the regulator ramps up the output. This is why mine doesn't have a connector anywhere for the LEDs. Please let me know as soon as you have some results! |

| Hi! You're great with the creation on the ringlight 4.1! Could you tell me the store were have you buoght the fiber "collector"? So I could create my fiber ring flash too.! If you want, I could translate your page and "tutorial" in Italian, so you could post on your site! Please, answer me! Thank you! Great! Alessandro ________ Fuzzcraft's reply: The bundles of fiber came from a dump shop in the Netherlands (Baco Army Goods). A few weeks after I got them, they ran out, so they're just sold out. Gone. Normally these are very expensive, so I really got a great deal for these two. If you can't find anything, ringlight 4.0 will be your best bet at a DIY ring flash. |

| Keep in mind that although fibre optic cables bend, you want to keep bends and the sharpness of the bend to a minimum. They will leak light around tight corners, so the 90 degree kink near the flash is not ideal. Otherwise, amazing idea! ________ Fuzzcraft's reply: I know it's not ideal, but then again, if you look closely, you'll see it's not really a kink. The radius is about 10 mm for the sharpest bend, which is well within specifications. |

| Thanks ! I think I'll go with a 7.2V NiMH RC car battery then... should work nice, at 3800 mAH . |

| Hello. On your reply previously about an AC adapter, I happen to have a few sitting around, one 9v100mA, and one 12v300mA. Would either of these work with your schematics for ringlight 2.1 as-is? or would I have to change any components to accomodate? I'm not good at creating schematics, but I can buy and solder anything required into place. Best regards, and thank you. ________ Fuzzcraft's reply: I'm afraid neither will do. You need around 14 Watts of power for RL 2.1, which means at 12 volts you need 1200 mA (= 1.2 A), or at 9 volts it would be 1600 mA (= 1.6 A). Remember, Volts times Amps equals Watts. |

| Great site, the ringlight explanations are very well done. The only thing not clear is what configuration you use for the battery pack on ringlights 1.0/2.0/2.1? is it 4xAA batteries in series for all 3 of them? ________ Fuzzcraft's reply: in my experience, the 1.0 would run great off of 4 AAs, but the 2.0 and 2.1 need 6 AAs to start properly. Your mileage my vary, I'd say just try it. Maybe the newer NiMH AAs are better than the older generation I have. |

| Just wondered what the 15 cab, and 2-10 cab would cost.. Delivered to 87035. Let me know, Bud Fuzzcraft's reply: You do realize that those cabs are simply not for sale, right? Anyway, just for fun, I ran it through the UPS cost calculator and came up with around US$600 for shipping alone. We're talking about sending over 100 lbs across the globe. I'm a Dutchman... |

| Hi There, awesome idea and great details on how to build this thing. I think I'm going to build a 90-LED one, and I'm likely going to make it AC powered since I only ever do macros at home (And I dont have one of the NiMH) batteries handy. One thing that isnt clear, do any of your schematics show option for AC power? Fuzzcraft's reply: no, AC power is not included in the schematics. Your safest option is to buy a ready-made AC/DC adapter that puts out the required voltage and has a high enough current rating, and go from there. |

This is yet another test. Please ignore  |

| I love your Fiber Optic Ring Flash ideas! Where did you find those heavy duty fiber optic cables for your Ring Light 4.1? (Where can I find some? ;-) ) I plan to build a Fiber Optic/LED combo. I'm using 8mm .5watt LEDs, 6 of them with a switch and I would like to add the i-TTL synched Fiber Optic as well. Thanks! ( Fuzzcraft replied on 28-02-2008 ) |
