- Yeast Attenuation & Beer Fermentation Problems In this video I talk about yeast attenuation and how important it is to beer fermentation. Most beer fermentation problems that aren't really problems are usually solved by understanding this phase of fermentation. I talk about why it's not up to you whether you want a short fermentation time or why bubbles in airlock don't mean anything. Some brewers wonder why they have to wait for their airlock to stop bubbling or just wonder when their beer is done fermenting. The only way to know is by checking to see if the yeast are done attenuating the beer, and that's done with a hydrometer. Check out the video, click on the link above and don't forget to leave a comment and subscribe...
- Palm Pre Death Grip Attenuation Palm Pre exhibiting attenuation once put in the "Death grip." Note that I say DEATH GRIP. Meaning intentionally bad grip. Attenuation to the point that service is no longer usable whatsoever, just like iPhone 4 when put into Death grip in a low service area. You guys need to keep in mind that this phone is TINY. My hands wrapping around it is not very far fetched. Yes, its exaggerated, however my normal grip is not far from this. Attenuation has NEVER impacted my performance on iPhone 4, even when reception reduces to 1 bar. I've never dropped a single call (even in areas where 3GS used to) and my data speeds seem almost exactly the same. Quality is actually hugely improved over my old 3GS, especially data speeds EVEN after attenuation. The difference with iPhone 4 is that the "weak spot" is a smaller target that is easier to find and easier to trigger. However, reception overall is a vast improvement over every other phone I've tested on ATT. I think Steve Jobs should have stressed this more during the press conference, that this is a TRADEOFF of the design. You get a thinner, more robust phone with huge improvements in reception, the tradeoff being that it has a weaker weak spot. Steve Jobs really should have used the word tradeoff to explain it.

- Nokia E61i or all Smartphones Signal Attenuation Can Be Easily Reproduced In A Low Coverage Area Excerpts from Apple website: "Every smartphone has a cellular antenna. And nearly every smartphone can lose signal strength if you hold it in a certain way.The opposite of amplification, attenuation happens whenever a signal is obstructed. All antennas — including television, radio, GPS, and cellular antennas — can experience attenuation. And with most antennas, the density and composition of the human hand can cause attenuation to a greater degree than some other materials. On a mobile phone, signal loss typically occurs when your hand attenuates the most sensitive part of the antenna."
- Olympus KA-333 Compaticord attenuation cable test The Olympus KA-333 "Compaticord" stereo attenuation cable is a useful solution for connecting a line-level audio source, such as a turntable, CD player, or tape deck to a microphone input, such as those found on many Canon and Sony camcorders. It has built-in resistance which drops the audio gain down to a level suitable for a mic input without overdriving or distorting, and also solves most problems with hiss and hum, which you usually get if you try to achieve the same attenuation by using a mixer and turning its output level almost all the way down. Of course you can make your own attenuation cable yourself using some wire, plugs, and resistors, but for those who don't already have the parts and tools on hand, this Olympus cable does the trick.
- LeCroy WaveAce Oscilloscope Series - Setting Probe Attenuation Passive probes are the standard probe provided with most oscilloscopes. Typical passive probes provide a 10:1 attenuation and feature a high input resistance of 10 MΩ. This high input resistance means that passive probes are the ideal tool for low frequency signals since circuit loading at these frequencies is minimized. Passive probes are designed to handle voltages of at least 400V, some as high as 600V. LeCroy passive probes feature an attenuation sense pin which tells the oscilloscope to scale the waveforms automatically requiring no user input. The LeCroy WaveAce combines long memory, a color display, extensive measurement capabilities, advanced triggering and excellent connectivity to improve troubleshooting and shorten debug time. With bandwidths from 60 MHz to 300 MHz, sample rates up to 2 GS/s and waveform memory up to 9 kpts/Ch (18 kpts interleaved) the WaveAce exceeds all expectations of a small affordable oscilloscope. Be sure to check out all the videos in this series for the LeCroy WaveAce. Available At Video By LeCroy.

- Blackberry Bold 9700 Signal Attenuation Signal Attenuation can be observed when the phone is gripped a certain way and a weaker signal exists. This can occur in any wireless device and this video shows it occurring on the Blackberry Bold 9700. The video was shot in an area where I get poorer service and you can see that I'm on EDGE instead of 3G. When there is 3G service there is no change in the number of bars of service. This isn't a video about how great or crappy Blackberry/iPhone/Android is. It's basically to prove a point, by showing is exists not just in the iPhone 4, that people are making a way bigger deal about signal attenuation than it really is...
