Trout, if you have a spare kit I would be interested as it looks an interesting project. Drop me an email if you do, my address is in my profile.

If it gets warm quickly that is a good sign as it means the heat transfer is working well .

It can go up to ouch before you need to panic .

but on a ride even a little moving air will keep it cool
just need to remember to dim it when stopped .

I have got more leds coming in this week and have plenty of Reflectors

had a work out and was a few quid out of pocket in the final tally but not worried .

for the same kit I supplied the others and if Steven is happy to supply the other bits the price posted will be £20 as have run out of offcuts of the Aluminium and will have to buy some more

if you want one start a new list on here and drop me a mail .

Not going to do the 6 led in the side of the case as its too tight to make a nice job of it but with a diferent case it might make a good un .

Trout, I'll start a new list, and have dropped you an email. I will also take a driver if Steven does another batch.

Well done Lipseal you must be well pleased, good beam shots and nice windmill too 😀

Still got a way to go, faffing & hangover have seen to that 😳 As a thought could you make a gasket out of inner tube rubber to seal the ends up with?

Oh and what size drill to use for the cable grommet that came with the trout kit, guessing 6mm?

EDIT: make that 8mm?

Stayhigh cheers, I used 6mm ( nice tight fit and the cable doesn't go all the way in had to cut it back, made it more flexable) drill and used a bit of glue around the grommet and where the cable enters plus the heat shrink just to finish it off, pity I didn't have any black that size. Has anyone got any ideas how to make the (smudges) battery pack weather proof?

Just a little tip on the cable and grommet put a zip tie on inside to give it some strength .

some old innertube and 2 zip ties work well .
or for light weight a condom 😯

Forgot to say on last reply that the connectors where from sumdge, just like the hope pop lock ones so it was a tight fit(the lions sleep tonight).

Ribbed or feather lite? 😆

Lipseal, nice job, beam shots look good as well. Just be carful, light building can become addictive.

Out of interest did you have to use any specialist tools or did you get away with the normal stuff you would expect to find in a cyclist shed.

Cheers CK, the only thing I bought was the glue off fleabay (plus the leds etc) all other bits in the garage stores. Was going to tap holes out but used self tappers as I have a good selection, so yeah all the usual stuff.

Hi Lipseal .... Point your light up in the sky southward ..... see if I can see it from Crosby!

If you're down anywhere near this way after dark ... or someplace in between, let me know ... I could compare it with my ancient halogens while I wait for Trouties next batch of Led's to come in.

Got itchy fingers here just AAA'ng ali to drivers and drilling the odd hole .... must see lumens!

Don't know when I will be able to have a go at one of these but really fancy it. I was wondering about improving heat dissipation so started Googling ally extrusions. Found this - http://www.birminghamaluminium.com/heatsinks_home.php

Just thought I'd share in case anyone is interested. You can also get simple ally radiant/heatsink from Maplin too. Thought if you used thermal paste between radiant and case and long screws through the radiant in to the internal heatsink you would get transfer up to the radiant. May be overkill but I'm Capt. Paranoid plus may add that pro look to the box.

I've recompiled the possible-Round-2 list from the past few pages, its a bit confusing, dunno how trout and bct keep up. If I've missed you or you shouldn't be in it update the list and repost.

by jingo it actually works!

just need some silicone to seal it up and stop the cones rattling (mis-aligned one of the angle mounts ever so slightly). no pics of inside as, quite frankly, my soldering is an embarrasment - but it works! i`ll post a pic of the finished article in a bit.

just need to sort the mount and i`ll be off.

it appears quite a tight beam so we'll have to reserve judgement till i've used it in anger but its 'bloody bright'(tm) - i can floodlight my pumptrack (about 100ft away at the bottom of my garden) from the balcony no problem.

big cheers to trout and BCT. jobs a goodun!

tee hee. could cut the case down a bit and probably will at some stage but its not heavy as it is. put a tamiya connector onto BCT`s power cable but didnt use the socket - cable is fixed to the head unit so detach the battery to charge.

all made using regular tools and good old fashioned bodging. the hardest bit was getting hte angle drilled in the right place to mount it to the box as i have nothing to hold it in place as you drill through

Looking at this, one thing that comes to mind is, would it be a good idea to chamfer the edges around the front panel holes/reflector opening, as there are a good few mm of overlap which might cut some beam spread?

Just a bit of parallax, holes are 20mm for a 19mm reflector.

not sure LS. my old solution was putting it in a waterbottle and seal the cable entry

however my new frame doesnt have a bootle mount so i`ve been taping the batt direct to the toptube. i generally dont ride if its sheeting it down so i was considering judicious use of a food bag and more tape for sealing on damp evenings

alternatively i`m sure there must be some tupperware in the world that is the right size! not very pro i know but then its dark when you use it!.

Good stuff fellas hopefully be a few more working ones along soon .

Thanks for updating the list too .

Just been making a jig to drill the stars so they may come predrilled for the reflector depending on spare time available .

Damo2576 - LED & Driver Kit)

Damo2576, this thread is now over 500 posts long and there is a lot of detail, however very rougly you'll also need;
A Hammond metal case (from maplins http://www.maplin.co.uk/Module.aspx?ModuleNo=33690 .e.g. N82AL) - Trout's L angle ali strip is cut for this case.
Battery pack (e.g. 8xAA battery holder e.g. RK44X + 8 rechargable AA's)
Thermal conductive compund for transferring heat away from LED ( e.g.Artic Silver or own homemade epoxy)
Various 2/3/4mm self tapping screws (the ali case is soft enough for self tappers or make your own thread with a tap/die set)
Fibre washers to place between the screw head and led

wonder if the plastic or alu ended version is easier?

the metal ended one you dont need to cut for the lexan/perspex as you use the metal plate as a guide and replace it.

the plastic ended you'll need to cut holes as per CK's light. i didn't have the kit to do this nicely so went for the metal plate option. it doesnt look as smart but its about what you have the tools to do.
