DIY guide request
ok, this may sound dumb, so feel free to call me out on it, but could some one post a how to video for DIY blades? I've been through the read through's and think i have it down, but a video woud be awesome.

I could post an after video. and just talk a step by step / piece by piece if that would work for you?

that would be pretty cool. I just got a rave 450 and it looks like il have to make some 350 night blades as no one make them ...to my knowledge.

The SWARM Heli club is going to be having a heli night some time in the near future, where the main topic will be constructing night blades.
I'll see if anyone has a digital video camera and an idea on how to use it. All I have for digital capability is a cheap web cam with lousy picture quality and no closeup capability. I have an older high end video camera that uses HI-8 tape but I have no way to convert that into a digital format for posting. I have a few tapes of things that I have filmed over the years, that I would love to convert to digital.

Hmmm...
Sounds like a good holiday project...and I need to build another set of blades for a more advanced battery/controller for IRCHA 2010 anyway.

I too would love a video. Some times trying reading it and do it is a lot harder than watching a video.
I can't wait to see the video, then I'll try and make my own. |

OK...this is a LONG project!
Series nearly complete as of 3-16-10 - 1 or 2 more videos to edit/up-load.
Long-A$$ project this is! List of parts: Digi-Key at www.digikey.com part # make-up color lens package size leds: 350-2046-6-ND INGAN BLU WATER CLR 0805 SMD 350-2047-6-ND ALINGAP RED CLEAR 1206 SMD 350-2045-1-ND INGAN GRN CLEAR 0805 SMD Resistor P40.2CCT-ND 40.2 OHM 1/8W 1% 0805 SMD 3-pin socket A26245-ND CONN IC SOCKET 3POS SIP TIN On/Off Switch - Radio Shack Catalog #: 275-007 6VDC 0.3A DPDT Slide Switch Battery 80-mah single cell lipo http://www.bphobbies.com/view.asp?id=A2416227&pid=W561531 Copper Tape 4516 Copper foil tape http://www.glasscrafters.biz/CTGY/foil 2-Part Automotive Clear http://www.sherwin-automotive.com/pr...?product=FC710 http://www.sherwin-automotive.com/pr...?product=FH612 Tools & Supplies Video: [ame]http://www.youtube.com/watch?v=1gJSmIS124A[/ame] Components Video: [ame]http://www.youtube.com/watch?v=7yJI1ZQMxVw[/ame] Blue Tape, LED Soldering & SIP/Switch prep: [ame]http://www.youtube.com/watch?v=kyf4uaIK7f4[/ame] (sorry video is rotated 90-degrees - only way to get work surface in frame & be able to solder) Note: The "Booger Technique" - you'll see in the video where I roll around the soldered LED & resistor - this is a simple "mechanical stress test" of the junction between the the two components. Introducing the blades, weigh-in, insulating the exposed CF to keep battery from draining too quickly, surface prep, where to place the copper traces and more blue tape: [ame]http://www.youtube.com/watch?v=1b0po1G4NCw[/ame] Attaching the copper foil tape: [ame]http://www.youtube.com/watch?v=4yBJSEPMJfo[/ame] Marking LED placement on copper foil: [ame]http://www.youtube.com/watch?v=P47ULvuN340[/ame] Adding the LEDs and copper traces over the LE: [ame]http://www.youtube.com/watch?v=FEGmvcYM4U0[/ame] Another continuity check, Battery placement, switch & charge port wiring: [ame]http://www.youtube.com/watch?v=7WuM7vSSvNY[/ame] P.S. - Thanks Jeff...

Final Video- Weights checked, CG's are VERY CLOSE, measuring clear-coat, recap & charge leads: [ame]http://www.youtube.com/watch?v=dO9Td6x-xsg[/ame] See the finished product (blades from 2009)in-flight: [ame]http://www.youtube.com/watch?v=RqisgAt1bVY[/ame] Maybe I'll edit the video for this below...kinda like explaining brain-surgery: I'm also going to show how the 'environment' of the blade helps us to "cheat" an LED with lower light output and drive it a bit harder than normally allowed. (observe your surroundings and take advantage & quite possibly why some have had limited success without employing resistors!) Red LED temps relative to others because of the "cheat": [ame]http://www.youtube.com/watch?v=6btztKgA4QE[/ame] Why Resistors???
If no resistors!!!
Ohms Law Voltage (V) = Current (I) x Resistance (R) or V= I x R --------------------------------------------------------------------------------------- Voltage Division across a Series circuit Vtotal = V1 + V2 + Vn... --------------------------------------------------------------------------------------- Vtotal = Single Cell Li-po Voltage Source --------------------------------------------------------------------------------------- Vtotal= Vled + Vresistor 4.2V= 3.2 + Vresisitor Vresistor = 1.0V --------------------------------------------------------------------------------------- Iled= Current = 0.020Amp aka 20mA V= I x R R= 50-ohm Power Watts = Voltage x Current 0.02Watts = 1V x 0.020A Smallest Wattage on 0805SMD resistor = 1/10W =0.1 Night Blade Circuit is 4 Series-Circuits in Parallel with a battery & switch. NOTE THAT ABOVE a 50-ohm resistor was calculated but a 40.2-ohm value was purchased. Why? 4.2VDC is the fully charged state of the battery - the moment the blades are "on" the voltage will be dropping. Majority percentage of the discharge will be in the 3.8 to 3.4 VDC range. Take 3.8V - 3.2V / 40.2 = ~ 15mA. Next version may have an AMtel chip driving the LEDs directly - then no resistors and an RF link to the x-mitter!!!

Glad you like.
Working on a Power-Point presentation for calculating resistors, LED selection and other points to consider before constructing.
Hope this cold leaves my head...sound more like Barry White today than I'd like to...except my lines are all about helis &$hit...so the wife is less than impressed.

Thanks for teh info and the vids. I am comfortable with the other aspects of the project, save for one. would also like to see a vid of how to go about soldering the LED's to the tape without melting the led.

Head cold is gone but business has finally come out of the "winter slump" (this is GOOD) so my time is getting short.
Fortunately, a friend of a friend has asked me to build a set of blades for him...so - when his blades arrive, I'll shoot the remainder of the build-series. So, coming yet -
