EasyCAP Gem or Crap

Posted on June 15, 2011 at 3:49pm 9 Comments

I have several of these, all shipped free in two or three weeks from DealExtreame


EasyCAP Model DC60 (DE# 8005707, SKU 5707) $8.60 black case, Windows ONLY. Has worked great for 2 yrs+

Device Manager reports "STK1150". CD has License Key for Ulead VideoStudio 10 and drivers install…


Air Force Academy had to wait for full COA, how can our best minds learn when they can't test fly?

This would work for me..

Verbal Approval/Waiver Authority, pending through review of applications

Too much power and pitch compensation is bad thing... not enough is bad too.

No ground crew today. Down view camera was installed.
Front camera view of todays flight testing of PID settings for throttle cruise 80 & throttle max 120, pitch compensation .30 Test battery a 2250mAh 3s lipo had 1 cell going bad,

I replaced battery and retested, but crashed flat and hard when I panicked and set Mode to FBW instead of Manual..…

Mark - Here's the latest ArduSlave code - - It show's sending cmds to, and requesting data from, the slave. Cheers - Pete

Here's the calling code from ArduPilot GPS_EM406.pde.zipGPS.pde- shows getting GPS and sending cmds to the slave. I think it would be very easy (and not stress the system) to connect ArduIMU and ArduPilot. I'm planning just that.

Good eye! It's an cold war era KM or (Caspian sea monster). As far as house boats go, you and I are about the only people who think that would be a good idea. Now I'm REALLY glad I found this forum. As I say to my wife, "I've finally found MY people..."

I was a Electronic Tech in Navy so house boats are up my alley. I am land locked in Colorado Springs, I love to hunt and fish ....

An ET in the Navy? I was an RM in our beloved Coast Guard! Yeah, I know, "shallow water sailor" (I've heard them all!) After tours on Ice breakers and patrols in the gulf of Alaska, I've had my fill of the deep blue! Now I just enjoy the view from Long Beach harbor.
My family has a cabin in White Pine Colorado, (near Gunnison). It's been over 20 years since I've been there, but we have plans to (finally) get back there this summer. Should be interesting...

Hi Mark,

I have a few RC planes, one is FPV, but no autopilots yet. Hoping to follow the lead of you and others here and assemble and autopilot using ArduIMUV2+ and yet to be selected flight computer. I'm a computer vision type and am considering the BeagleBoard or GumStix or similar in order to have some image processing power available.

Are you running your autopilot code on an ArduPilot board or something else? Also, what's a Ventus HCX? I'm impressed that you have a Stryker flying on auto and look forward to seeing you win the SF competition in April.

Thanks for the system descriptions Mark. I've been using 2.4GHz video (from BlackWidow) on my 6' Telemaster (7.5 lbs, AXI2826 13x7 prop 4S 4900mah LiPo), but video downlink quality isn't consistent enough (no diversity receiver). I'm thinking about ATV (amateur band 434MHz/70cm), but that's probably more expensive than other options. What's your advice for FPV?

I got a general class license a few years ago just so I'd be legal on 2.4GHz at 200mW. Since there's no Morse code requirement anymore, the general and extra aren't much more difficult than tech.

Is the 910MHz TV signal much better than the 2.4GHz, and are you using a diversity receiver?

Thanks for the info. So hooking up the system without a long coax cable hasn't harmed the amp? I thought that the DX7 puts out about 200mw and the amp input was 100mw and we had to use a -4db or so attenuator.
