I have pretty bad allergies and when diving locally (summer allergies bad) or in the tropics I have to have the drugs. out. Based on recommendation by my ENT (prior to starting diving), I take Nasalcrom to calm down the sinuses , Opcon-A eye drops which provide great relief from itchy eyes and...
Having built 4 LED lights so far, I would think if you stay in the 10w range with a decent aluminum heat sink inside. I think 1/4-3/8" aluminum disk the diameter of the housing you should be OK. This would give you 3 cree Q5 or equivalent . Run in series with 1A . More and you are likely going...
Head south to Hatteras. Look up Outer Banks Diving
Call ahead and Amy will let you know what kind of group is signed up for the days you are interested in. Their boat holds over 20 divers and is quite comfortable. I have been on the Proteus and the Dixie Arrow with them. Great dives and lots of...
The iPhone was a company phone and had to get turned in when we changed phone plans (moved from company provided to personal - expensed). So now I am looking for deocsoftware for my Sprint EVO
I just switched phones to a HTC/Sprint EVO. There is one app I really miss form my iphone and it is ideco pro
What alternatives are there for android phones?
I would like buhlman calcs to match my Shearwater pursuit.
DAN and an all perils / replacement cost rider on my homeowners policy for dive gear and camera equipment. I had great assistance form Wisconsin Mutual. Flooded my camera (Nikon D200 + new 60mm) on a trip to Wakatobi last fall. They had the replacement check in my hands in less than a week...
Sad to hear. If they won't talk to you now, what about when you NEED them.
Conversely I had the opposite experience with Wisconsin Mutual. My camera and housing were covered as a rider on my home-owners policy. Flooded the camera in Wakatobi (D200, Ikelite housing and 60 mm macro) . They had...
I wonder if it is off in its readings or merely slow to respond. I have a cobra, (actually now my wife's) and it is VERY slow to respond to temperature changes. It takes minutes to register the change from passing through a thermocline.
Check it out in air va a known good thermometer. Then dump...
Well it survived the first dive. 85 foot max depth tonight.
It puts out an amazing amount of light. The "area light" of the ring light complements the spot of the canister light well. I used a flash as supplement, but it would not have been necessary.
First shots at: Mark Bronkalla's...
Conceptually pretty simple.
It is 2 rings - one aluminum and one acrylic. The electronics are glued down to the aluminum ring with silicone heat sink adhesive (from DX). The outer edge was cut on a metal cutting band saw. I drilled a hole in the table as a pivot point for each piece and cut them...
I just completed my LED ring light. 6 CRE XR-E leds.
2 strings of 3 LEDsm driven at 1 amp each.
Current regulator is 2 7135 boards (3 chips each from Deal Extreme)
It fits an Ikelite housing and macro port.
First dive tomorrow night with it in Lake Michigan.

1/2" acrylic with holdes drilled for the current regulator boards and the LEDs. Holes drilled with forstner bits. Ring for wires cut ont he lathe.
Finished a second light. This one is for my wife. This one uses a regulator board with 3x AMC7135 from Dealextreme. This is very small and inexpensive. It can be mounted in the light head. however it does need to have an added heat sink (gets too hot otherwise). Using a piece of copper...
The airspeed book is great. As stated above, go with LED or HID. Both offer better efficiency, higher color temp and are cooler running. The book was my jumping off point for building LED canister lights. Working on the second one, for my wife. Next project is a LED ring light for macro work.
On the scuba-tow link.... Any website that sells "HHO" plans has to be suspect. Either they are ignorant and passing off plans for a system that does not work (the HHO BS) or merely crooks. Looks like this guy is just selling any plans he can get hold of regardless of usability or quality.
