Alesis M1 Active MK2 repair – Flashing Blue LED FIX
Sorry for the poor image, done on my phone, but its to show you how easy it is to fix, read for details below. —————————————————————– The flashing blue LED and loss of sound on the Alesis M1 powered monitor is caused by failure of capacitor C8 (220uF, 35V) on the power supply board. It dries up due to its proximity to resistor R4 (47K, 2 W) which gets very hot. This is a design fault. Procedure: Remove the power supply board (4 corner screws and 2 mains connector screws) and disconnect the two plugs. Carefully desolder C8 and replace it. Its value is not extremely critical (220 to 470 uF will do) but it should be a 105 deg. type, preferably at 50V. Remove R4 and replace it with a similar resistor with its leads bent so that it is nowhere near C8, otherwise the fault will return. One end may be connected to one of the existing R4 solder pads (furthest from rear of board), and the other to the top end of resistor R3. Check that you have connected it correctly by inspecting the PCB tracks. It was recommend to us to replace C35 (1uf/50v). We did not do this, and can not see what advantage it has.. !!! Replace the board and all screws and plugs before testing.!!! IN THIS VIDEO WE ONLY REPLACED C8 that was all that was needed. we pushed the existing C4 away from the new C8 capacitor in both speakers . It was an easy fix. If you know how to solder and de-solder, you can do this. I could have done this as a newbie, but my brother is more …
This is a test drive of my 4 year old Proton Savvy compact car, 1149cc Renault D4F, 75BHP @ 5500rpm, 105nm @ 4250rpm, Galvanized high tensile steel monoque chassis, front wheel drived, sequencial gearbox (manual gearbox anatomy, no torque-converter), bore x stroke 69mm x 76mm, in-line 4, drive-by-wire throtle body, multi-port fuel injected, SOHC 16Valves. Front suspension is McPherson configuration, lower control arm mounted on square type subframe, rear suspension is programmed deflection torsion axle. This gearbox is basically anatomically similar to a manual tranmission, having a single clutch plate and 5 foward ratios with reverse. The shifter in the gearbox is controlled by a hydraulic actuator and the clutch is controlled a hydraulic clucth actuator pump. The pressure for the hydraulic system is built by a main electrical pump. There are some issues with the gearbox hydraulic main electrical pump due to insufficient electrical reservoir resulting in undervoltage during shifts which caused overheating, jamming and premature failure. Critical failure at 36000 km millage. Replaced the main electrical pump which failed due to undervoltage resulting in loss of pressure for both the hydraulic shifter actuator and the hydraulic clutch pump. Manufacturer refuses to admit design fault. Basically the current ratings between hydraulic system and the cars electrical reservoir were mismatched. After expensive repairs, the same symptoms of rough and jerky gear changes still …

Fostex Kotori 201 — Design your headphones — Unboxing
1:25 for the product 1:54 for the headphones 2:44 for the first look 3:05 for the hands-on 3:51 a surprise! This headphone is customizable. You can pick the colors for all of the parts used (excepts the inner workings of the headband and the drivers) and there is a lot of choice for them, some are translucent, powdery see-through, completely opaque, etc. Product page: kotori.fostex.jp Design and then purchase for 14000 yens (~175$, Japanese resident only, or Tenso.com users): kotori.fostex.jp Pre-made color schemes (not recommended, lol): kotori.fostex.jp Cost me like 210 dollars in total, best headphone ever. Lol just kidding. It’s a great sound-for-dollar ratio headphones, and I couldn’t find faults to the sound basically, and I have a lot of experience with headphones. I’d say for audiophiles out there that the sound doesn’t benefit much from amping, it’s a VERY portable-device friendly device, more so than Grados. I’m going to post my nitpicks and video review soon, but I just need to listen more to it, and use my amps to push it to its limits. I don’t believe in burning-in much but I’ll try to listen to them for at least for 25 hours, lol. In order to buy this headphone you can either use Gizmine.com US based website (www.gizmine.com for one of the two ugly pre-made color schemes, and overpay for them at 259.99$, or subscribe at www.tenso.com and then enter your virtual Japanese street address plus Phone at checkup on kotori.fostex.jp or use Tenso Japanese Buying …

Did design flaw contributed to the crash of Air France Flight 447?
Question by SugarBethMiddleton: Did design flaw contributed to the crash of Air France Flight 447?
I did some research and it appears the Airbus has been manufacturing the rudder system which is too sensitive and that contributed to the demise of AA Flight 587 in the US in 2001.
Do you believe that’s true?

Answer by belfordrocks
Absoultely not.
The most likely scenario is that when passing through the thunderstorm, the tiny tubes on the front of the plane got iced up. These tubes are used by the computer to determine the plane’s speed. When these tubes got blocked up, the computer couldn’t read the right speed. The computer thought the plane was going too fast (as a result of the iced up tubes) so it decreased the speed wrongly, making the plane fall down.
A very similar case happened in 1996 by a Birgenair Boeing 757 in the Dominican Republic.
