    Long way round

    Ok as it is so quiet tonight I thought I would try and get some feedback for my "lomg way round" light. Well it isn't quite a light yet just a housing.

    I have plenty of lights but fancied going back to small battery pack, longer run times, lighter wieght and just less faff.

    So when I read Trouties Regina reflector thread I thought may have a go and then I read brad72's thread I just had to have a go at the spikey look but a bit smaller as it would be for just 2 Reginas.

    Thread here : Latest Build - Triple XPG plus XPE spot

    anyway made a complete mess of it as you will see in brads thread but didn't want to start again.

    The reason I would like some feedback is really to get opinions of what to do next whist I wait for the reflectors to turn up as there won't be anything left of it if I tinker any more.

    I would also like to hear views on using a remote switch, I like the thought of being able to put the switch at fingers reach, be it on the hemet or bar. But in the end do they end up being just more faff to mount and remove? I may have no option though due to lack of space.

    Nice looking light.

    No advice, 'cause it looks good to me, just a question, are those "round bottom fins" I see?

    Anodize it!!!
    Seriously, the light body looks great.
    Issues are the usual.
    You made a seriously small light, so where to put the switch?
    I prefer the switch on the light itself. Usually on top since most of my lights are helmet based. Two Regina reflectors will surely be a helmet light.

    If the rear chamber is too shallow for a switch/driver then the remote switch would make the most sense.

    Some like the remote switch. To me it's just more bits to attach, find room for, snag on tree branches.............

    Great light design though. Keep up the great work.

    odtexas, thanks for the reply. That's what I keep thinking about an external switch, just more wires, I may have to try and fit a button from a mouse to the back.

    Beautiful light and you said it was stuffed. Like any artist you were just building on the initial idea,

    Have to agree that anodizing would look great, I am tossing up the DIY route.

    As for the switch if you are using the bflex then just use the button off the PCB. All you need then is a waterproof button cover thingy and your done.

    Again beautiful work...how many hours out of curiosity

    I prefer the switch to be remote from the light. It is a bit more gear and adds weight though. It also is another small fiddly part to make. IMO it is more important to have the remote switch for the bar light. If you meet an oncoming trail user, you can dim the bar light quickly and just turn your head slightly to avoid blinding them with the helmet light.

    What driver are you planning to use? If a bflex is the choice, you might try doing an integral switch along the lines of how I have done on the light covered in this thread....

    5 cell 18650 holder

    Your housing is quite nice! I have used a cutter on my last couple housings called a keyseat cutter in the US. I use this to "undercut" areas that are not critical dimensions and are just excess metal. This helps get some weight out of the housing.



    The area between the bores for the reflectors was cut out with this type of tool as was the o-ring groove that retains the reflector cover and seals the front in this pic.

    It looks like half a Harley V-twin motor, you should call it the Electra-Lite. Then if you anodised it blue it would be the Electra-Lite in Blue.

    Ok I'm going to put it back in tne lathe yet again and bore the back out a little deeper, then I think I could just about use the bFlex switch.

    Brad72, so far I have spent about four hours in dribs and drabs.

    vancbiker, I too use one of those cutters however I only have a lathe and a little milling slide attached so don't want to remove any more 'till I have received the reflectors.

    Thanks but I think that in my case I'm just insane

    I had to have a chuckle when I put it next to the first light that I ever made ( back in the old days when LEDs were new)

    To think I had trouble finding room for the switches in that too.

    That is some remarkable progress! Keep up the good work. I could see a helmet with a couple of them on top.

    Thanks!

    Put the switch on top right were the Bflex meets the lights. You only need the surface area to mount the pic for heat managment and as long as the LED's are mounted to aluminum directly behind the LED you should be ok as far as a thermal path.

    Thanks for the advice. I have got this thing up and running (Switch hanging out the back for now)and took it out in the dark to get the idea of the beam.

    I like it!!!! but it is very obviouse that it would be helmet use only. So as it will be permanently attached to a helmet mount then I may as well build the switch into the helmet mount.

    For the roadies a twin Regina light could make a great bar mounted road light.

    How would you compare the beam-pattern to MC-E with Boomerang?

    I'm pretty much done for now. will just get me a cheap helmet mount from Halfords (the same one as OverTheHill has used)and mount the switch to that.

    I have to say that I nearly lost the will to live whilst adapting the reflectors to fit the 10 mm square boards but I didn't want to wait weeks for some round boards.

    Some pics...

    If you want a far reaching beam with little spill so as not to annoy oncoming traffic then the regina is Ace
    if you want a flood beam out to about 35 mtrs then the MCE on a boom is good .

    Now with switch

    Quick update now that it's finished.

    I have at long last managed to fit a switch to this thing. I unsoldered one from an old dumped video recorder and it is tiny when put next to the bFlex one, I also used the rubber button cover from the VCRs remote control.

    Went for it's first real ride last night and I'm very pleased with how much throw you get from just 2 LEDs and there is also a nice amount of spill so as not to be too tunnel vision like.

    I must admit that this was a real pain to build.

    Nice job mate. It's hard to tell just how small it is in a lot of the photos. Are you now planning your next build, or are you satiated for the moment?

    Thanks emu26

    bsharrard thanks, it isn't actually that small and could have been smaller with optics and a smaller driver. The Regina reflectors are quite deep plus the need for a front glass and something to hold that on too and you end up with quite a deep light.

    I had an old bFlex that had been soldered and unsoldered so many times from other projects over the years that I wanted to give a permanent home as I didn't think it could take any more soldering and I ended up having to solder a couple of wires directly to components on the board (don't tell George).

    No light building for a while as this one done my head in.

    I thought I was alone in doing that. I should have realized we all have the same disease. I've lost count of the nights I've kept myself awake conceptualizing my light build. I think my wife is looking forward to my current light being finished.


    You'll be back.

    Trying to sleep when your head is full of ideas and measurements is not easy.

    What really keeps me awake though is that thought we all have.... "I wonder if those parts will arrive in the morning" I hate the waiting bit.

    Some more photos to show that it's not actually that small. I have "designed" it to be bar or helmet mounted as I think it makes a good commuter light when on the bar.

    I avoid commuting by bike as I live in London and it's like a war on the road but sometimes It has to be done.

    Forgot to add that the completed light head weighs 54g without mount.

    Thanks BrianMc

    The road light thing is just my opinion and I don't know what actually makes a good road light so I will try and take some beam shots tonight, I have some but they are not too good.

    I can tell you that I used to ride on the road to the trails with my 7up on med and cars would pull out in front of me, if they stopped at the trafic lights and I ended up behind them I would put it on full and fill the whole car with beams while they sat there waiting for the trafic lights to change.

    Thing is, in the few road to trail rides I've done with just these 2 Reginas cars now get out of the way and don't pull out in front of me. Maybe it's simply because they can now tell It's a bike and with the 7up just got confused. You may want to do a triple regina if you ride fast dark roads.

    I no longer use the 7up and find that for trails my DIY quad on the bar & twin Regina on me head is more than enough and for the road riding that I try not to do the twin Regina on the bar is my light of choice (I have a few to choose from )

    If only I could only get my 7 ups front off then I could use the leds to make more small lights.

    With Troutie's seconding of your reaction, I'd say it's a STRONG possibility.

    Yeah, it's a bit childish to retaliate like that, but when they stupidly endanger your life they are lucky all they are getting is an excess of photons and not a photon torpedo. Right Scotty?


    Here they try to avoid stopping at stop signs especially right hand turns. So hooking or attempting to hook cyclists is my status quo. They are used to 5 mph bikes not 15-25 mph ones. SLow bikes are Ninja or weakly lit. With 900 lumens from the two lights on low, I am fairly bright = not your usual bike. The low beam is a bit wide at 18-20 degrees FWHM (Carclo 10417's on three XPG R5s (fairly early ones: very white) so its glare made him hesitate just long enough he was really going to make me brake hard to avoid hitting his side. The driver was just starting to resume a roll, so he got my high beam (half power) to the side window as I poured on all I had to get by faster. Likely blinded him so he couldn't see to pull out. If so, I don't feel too guilty about it. I have a helmet whereas he has a cage with all the safety stuff. If he isn't going to stop and yield right of way as required to a vulnerable vehicle, I will use whatever means I have to avoid a collision as required by law. I have also had one do the same but they didn't hesitate and I had to yell at them to pick it up and yet still I had to slow, as they looked up into the mirror to se me almost to their bumper. I shouted: "It has an accellerator, you know!" (I mean, if you are is such a hurrry to pull out like that and can't keep ahead of me, what gives? ) The half amp output of the helmet light into their mirror must have made my feelings known at the light, as the next time that vehicle exitted that street as I was coming by, it waited.

    When I muzzelled the large side spill of the low beam with an amber snoot, I lost most of my 'be seen'. However without the snoot two drivers have gone by reving the engine or tooting the horn (not laid on just a tap)., This indicartes their unhappiness with my low beam glare, but they may be wimps. However none have hit their highs demonstrating real displeasure. Good thing as I can double my output and aim my downturned high right at them. A la Crocodile Dundee: "You call that a high beam? THIS is a high beam!"

    So I may want to back off the low beam an intermediate amount. I will do a drive by to see if the drivers were crybabies or have a legitimate beef. Anyway, the Regina reflector has me re-assesssing the situation since there appears to be a decent solution.

    Yeah, you need decent spill and a bright center to get that. They seem to sense my speed better (change in amount of glare until they are past the edge of the main part of the beam?) One of the reasons I need to drive by of my bike and helmet.

    The glare/spill balance is much more critical to safety and sharing the road than I suspected.

    Well dude...

    1. I'm glad to see your light on a proper bike. (Here's mine)
    2. It's nice to see more sensible designs now. The double Rubix bars / Wall-E helmet is impressive...but just plain silly when it comes to powering. Also rude to use that much light behind your poor riding buds.
    3. Finally...you win. (so far) I can't wait to see what Troutie does with a double'gina...but for now...your light is one that I'd buy if I hadn't already built my own rendition. Tops, man...very slick.



    Mount is Exposure, correct? Do they come with that mounting stud too?

    Chears chelboed I just wanted to get back to basics Nothing fancy just a nice little easy to drive light but still with the bflex features that I'm used to.

    It was getting a bit competitive with lots of mad lights, great fun 'till you have to buy the batteries.

    I have a family of lights that I have made ranging from a few twins, quads and the 7up that I never liked from the moment I turned it on. As you well know you get a great beam from the twin Regina.

    I don't want to win anything and besides you got yours finished first (I think). Oh and at least you have done some beam shots....I have just got in from doing some and they are crap with my camera so I won't bother.

    Yes Exposure mount it comes with the thing they call a cleat and it is permanantly mounted on my bike so that I can just clip in my light of choice, Expensive but worth it IMO It's been on my bike for years now and I have one of those cleats on each of my lights.

    I'll have to see how the XP-E helmet / G bars looks...but I'm pretty dang stoked on the Double Barrel Regina. I already have a second (smaller) housing complete and ready for a couple of emitters. I was considering a remote bFlex though...b/c of the modes. Not for me, but to sell to a dude that's stoked on my first one.


    As nicely finned and the amount of housing you have there...I'll bet that thing doesn't even get warm, eh? Mine stays very cool.

    I can get very nerdy and post a temperature graph if you want but I think mine got to 54c and stayed there in ....... I can't remember I'll post a graph.

    Each square along the bottom = 1 minute and it sat in still air in my very warm 28c living room.
    Out in the real world it only gets to skin temp and that's in our summer. I like the speed that it cooled when I turned it off and shows it isn't holding the heat.

    I'm going to have a break from lights for a while and get more riding in. Will see what people are building in a few months time.

    BrianMC I tried to do some beam shots but my camera is useless for such things, so I did a video of it bar mounted so that you can decide if it makes a good road light or not

    Please forward to 1:20 for the beam, I got a bit carried away

    Thanks. Nice effort with the video.

    It is actually a lot like my high beam unit but with a lot more spill. It is narrow enough the light above the horizon should not be an issue. If on a helmet, you could aim it down for oncoming.

    My issue is the low beam which needs to be wide to be seen but not above the horizon so as not to blind. I have an idea of how I might acheive that.

    very nice light build! I thought getting back into biking would help to pull me out of my torch addiction. Guess I will be spending more time back over at CPF looking for parts.
