content: I've just received an e-mail saying Rigol have issued a new price list for their products. It looks like we are going to see an increase of between 10 and 15% on the majority of equipment by 15th April, so anyone thinking about buying something might want to order quickly!

Our 10% discount code is still valid if anyone is interested in buying before the 15th - enter 'rigolcomp' at checkout.

content: Sometime low price/higher quantity sold gives more profit than higher price/lower quantity.But, honestly 10-15% is not too much of a raise in price. I do wonder if the raise in the U.S. Dollar will start having any deflationary impact on this imported gear though.It will be interesting to see in 2015 if there is any competitors who will even come close.Surely Owan, and the others will try. Or has Rigol spanked them so damn hard they are just going to give up?

content: Here in Dubai it would be fair to say that local radio might be a bit 'lacking'.I started listening to the Amp Hour show in the car but ridiculously, my factory stereo wants to restart the mp3 from the beginning every time I switch off the ignition, and then it's a huge ball-ache to skip through the file to pick up where I left offSo now I have one of those Android 4.2 units (made for my car model) which has wifi. I just drag and dropped a whole folder of Amp Hour to the car wirelessly.And I thought that was a cool story bro.

timestamp: April 08, 2015, 11:28:15 am
content: A week or so ago I tried listening to TAA when travelling to my assembler, about a 2.5 hour round trip. I listened to the bumper Chuck Peddle episode. I'd not downloaded it, I just streamed it over 4G and into the factory fitted car stereo via Bluetooth. Amazingly, it worked perfectly, no drop out at all, but it looked like it buffered a long way ahead.This was through an Iphone 6 plus. You have to do some gesture jiggery pokery to use the streaming UI so you can operate the controls. Once that was done the pause/play controls operated through the car's touch screen.When I got out of the car and then back in, even though I'd taken the phone with me out of BT range three times on my journey, it started off automatically from where it left off.I don't do many longish car journeys, but I found TAA to be good company.

High voltage spark types. - Page 1

author_rank: Super Contributor
timestamp: April 06, 2015, 04:44:40 am
content: Can someone tell me the difference to the to high voltage sparks bellow? The first one is a thin blueish with the distinct sound spark. The second one is thick, orange with a hissing sound.Is it just current difference? It is from an old smps for neon tubes. It has a switch that changes the spark. I couldn't find infos for this device (two step dimmer?).Alexander.

author: IanB
author_rank: Super Contributor
timestamp: April 06, 2015, 05:19:21 am
content: A spark is a low resistance short circuit. The ordinary "spark" that you see, for example from an ignition coil, is starved of current and so the spark goes out immediately after it starts. If you make lots of such sparks one after the other you get a clicking or buzzing sound, which is the sound of lots of sparks close together with gaps in between. On the other hand, if the electrical supply does not run out of current once the spark starts then the spark turns into an arc, a continuous hot conductive path for electricity to flow through (like an arc welder, for instance). Such a continuous arc makes a sound similar to a flame.In every practical application of arcs the supply is current limited. This is important, since as noted above an arc is a short circuit. If you create an arc in a circuit where the power supply has no effective current limiting (for instance a grid utility power system) then the current will be enormous and an explosion may occur.

content: Another example is the gas lighters without battery. They have a piezo, and by applying pressure, the voltage increases until a spark happens. That is a thin blue spark. Something else is a transformer of 20kV for Neon lights. That has more power, and it can make a buzzing glowing stable arc. There is a lot of energy in that arc. An electric welder uses that arc to melt metals.

author: HighVoltage
author_rank: Super Contributor
timestamp: April 06, 2015, 09:21:15 am
content: It seems to me, the difference is in spark time duration.The first part of the spark has a duration of a few ms, then turns off and the spark channel breaks down and then it turns on again with a new spark. This is repeated by the frequency we hear, like 50 to 100 Hz, I would guess.The second part of the spark has a much longer spark duration and the spark is sustained and stays on all the time.

These devices are quite different from one another, despite having the same name.But regardless, in order to build any kind of chip, you probably need access to a silicon fab facility, and you'll probably need the right computer technology to produce the chip design in a format that the fab facility can handle. You also need a bit of specialized knowledge in how to design the circuitry, and how to implement the design in silicon. This is not a trivial task.Have I completely misunderstood the question?

Interesting 3140 Hall sensor failure - Page 1

author: Seekonk

timestamp: March 27, 2015, 06:39:04 pm
content: On a project I was using a Chinese clone 3140 Hall sensor. Needed to do some rewiring and forgot the color code I had used for the wiring. It worked normally prior to the rewire. Knew the + supply wire but was left to guess common and NPN sink. Must have gotten it wrong the first try. When it showed some life it would turn on but not off. When I tested it later it operated as a perfect latch. South pole would turn it on. It would stay on till it saw a North pole of a magnet. Could be useful if I could depend on it working that way.

I would have expected the open collector transistor would have just shorted from reverse voltage. I can see where this could have a trouble shooter scratching his head, well it got this far in the program the sensor must be good. Just thought it was an interesting failure.

Capacitive touch screens - Page 1

E.g. there is a capacitive touch screen in a cell phone and it can start to behave in a wrong way; for example I click on one letter and it writes a different letter or several letters in one click.So an error can be caused by a touch screen itself or not. So my idea would be to dismantle the cell phone and measure the touch screen somehow. Possible way or not a good idea?Thank you for feedbacks

author_rank: Frequent Contributor
timestamp: March 26, 2015, 02:05:36 am
content: You are going to learn more by reading many of the articles on capacitive touch screen operation on the net. Touch screens have chips that read capacitance between horizontal and vertical bands. These portions of the circuit or pretty sensitive. Also, the chips are programmed with offsets, based on surrounding structures and metals. Once you build a touch screen into a device, you sometimes need to recalibrate it and load different parameters.It is educational to take apart a broken device and look at how the touch screen is laminated to the cover glass. (Be careful, when gorilla glass or dragontrail break, the shards are really sharp.)The most likely scenario for failure in a device where you have a wandering touch is the conductor for one of the shifting axis is failing. For example, if the touch is shifting side to side, then plating or conductor for a vertical region is failing. Like many things in screens, it is not really possible to fix without really expensive equipment. And often not even then.
