Re: The FrankenBebi Project

New news at The FrankenBebi Project..

First up, we now have our own domain, FrankenBebiProject.org and new email addresses to match. Shiny new toys for the holidays. If you have our older pages bookmarked, you will be forwarded to the corresponding page on the new site. All the old email addresses are still usable, but as always, it is best to update your bookmarks.

Along with the new domain, we have made a few changes to the web pages, mostly just housekeeping issues. We have however added a quick-mail form to our contact page so you can contact us directly without having to copy and paste our email address.

We have also added a short (5 question) survey to the home and news pages on the site. If you have the time, please stop by and fill it out so we have a better idea of what the community at large wants from the FrankenBebi anchor light. No personal information requested, just the facts ma'am.

Meanwhile, testing of existing designs continues along with some new experiments by our latest team members.

Igor will have the full newsletter for late December mailed out sometime this weekend. See the website for how to subscribe if you want "the rest of the story"....

Thanks again for your interest and support.

P.S. At this time, we don't have any plans for a blue light... but you never know, it should be a trivial exercise given a decent source of decent "Blue" LEDs. Make sure you fill out the survey and make your request for new features in the last question on the survey

Re: The FrankenBebi Project

I have one Owl light now on the masthead and will be ordering two more as soon as they are ready for show time. Living aboard on a mooring, I want one on the Bow and Stern in addition to the anchor light. Being visable in an anchorage or mooring field is a GOOD thing!

Re: The FrankenBebi Project

Out of interest Igor, which LEDs are you using?

Re: The FrankenBebi Project

My Bebi in the cockpit just burned out, actually it started to flicker really bad. Waiting to order one of the Frankenbebi's as soon as I can.. Keep up the good work.

We are using C503Ds with a Vf bin of 29. You can grab the spec sheet here
Does the 15deg viewing angle cause any dark patches between the LEDs on those? The spacing would appear to be 24deg.

Re: The FrankenBebi Project

cona-
The beamspread that is nominally quoted on LEDs is not an absolute cut-off, like a nav light's. When a maker like Cree says an LED has a 15 degree spread, that's 15 degrees to a certain illumination level. So if the LEDs have a 50% fall-off at 15 degrees, they will have full brightness for 15 degrees, and then less brightness beyond that. IIRC that could mean they are still more than 50% brightness at 20 to 30 degrees, so the overlapping from one LED to the next covers the extra degrees between them. (Adding the dimmer light from two adjacent LEDs allows them to combine and still provide "enough" in the gap.)
The overlap and the fall-off will be in the technical specs for the LEDs, but those never make it to the best-seller lists. Or Hollywood screenplays.<G>

Yep, graph is on page 7 of the data sheet. Tails off to near zero quickly. I was wondering if there was any visible taper in the emitter light in real life.

No visible taper in real life... From over 25' individual LEDs cannot be discerned. Under 25' it's too bright to look at comfortably.

Quick question... was this an original Owl? and did it have the the built-in photoswitch? How old?...

If it is an original Owl with the Bebi-Electronics Sticker still on it, once we are in production you can return it to us, and we will replace it for the cost of shipping. As we have stated before, we are not associated with the original Bebi-Electronics but as Michael and Kendra would replace it if they could, we will try to do the same for their original customers. Get in touch with me via the website for additional info on how to get your dead Owl replaced.

Also I would like to say thanks again for your efforts in Boot Key Harbor.

Re: The FrankenBebi Project

In another thread I asked about having PV and battery for one week with wifi or by control. Paul E replied that bat weight too much and PV size too large for top mast. Maybe need future Batts and more efficient PV 20%? It will happen.

I don't know how I missed this post, but thank you for the offer and I can't wait until I have another on my boat again. Yes it was the original Owl with the sticker on it, it's about 4 years old I think. I'll get ahold of you on the site and again, thank you for the service! We will be buying a couple more I'm sure.
