How to specify Flow Control in PyVISA - Page 1

content: Hi.I've downloaded PyVISA, the Python VISA plugin, and it works just fine in both Python 2 and 3. The only big problem is I can't seem to get flow control enabled.I'm trying to write e.g.Code:instr.flow_control = xonxoff, but that doesn't work. In fact, I can't seem to find the valid arguments anywhere in the documentation or elsewhere. I don't know if this is a bug, only partially implemented or what, but I'd be very glad if someone could help me.The methods describedheredoesn't work. I get the same result as "zhengqinggan".Magne
When the most absurd solution becomes the best solution  - Page 1

content: I'm a student in second semester senior design. While working today we needed five distinct square waves of varying frequency and phase to simulate five motor encoders. In need of three more generators (Our scope has one generator channel) I went looking around and apparently we're one of the only groups that got a standalone unit. After realizing this it became clear that the easiest, though certainly not the best, solution was to pilfer three other scopes and just use those.This leads to the most absurd setup I've seen in a long while since none of them are actually being used as oscilloscopes.So, there you have it, a 12 channel oscilloscope based $10,000+ square wave generator.

It's a pretty simple game: Read analog-ish inputs, generate digital/analog outputs.The fun part is fitting all your logic in 9-14 instructions per controller...I had to print out the in-game manual and refer to it to squeeze that extra bit of logic in, and (ab)use the conditional bits a lot.Kinda ironic that I spend my week working at a 9-5 as a software dev and then spent my weekend playing a make-believe version of one, but eh....For $15, it had pretty good entertainment value!

Really ESD-safe boxes?  - Page 1

content: HI!I recently bough "20Pcs Pink Mini ESD SMD Chip Resistor Capacitor Component Box" from a Chinese site and I'm suspicious whether those are really ESD safe.So I did a few little tests to try to see if they behave like boxes coming from a trusted local supplier.The pink boxe is the Chinese one, the dark blue from the local supplier.In the first test, the electric field is high enough to trigger the NPN transistor, that lights up the green led, and in the second test it moves water...This is what happen when I rub the box on my head to try to generate some static charges:Any comments ?Thx!

So with a 'grand master' RFID card in-hand, I got exploring and let me tell you, this place is enormous. This venue includes a 2000-3500 person capacity ballroom (the largest in Australia), three theatres with the largest seating 8000 people and several exhibition halls ranging from 13,600 sq.M to 19,000 sq.M. Among all of those there are 70 meeting/conference rooms and open spaces for all sorts of events.The 'guts' of the building was just as interesting. 955 Cisco access points scatter the building, 10Gbps fibre connection and more digital displays than you can poke a stick at. Very impressive venue. Attached are some photos (sorry, I can only show you those taken in the 'public' areas).I believe yesterday they had an open day to the public, did anyone from here go?

Both of the Google docs accounts are investigated and the hate speech is found on both accounts, and the 3rd person is listed as the owner. The 3rd person claims no knowledge of any of this.We discover that a Google doc can be created, shared with a 3rd person, and the 3rd person can be set as the owner without their involvement at all, and the doc will automatically appear on their account with them listed as the owner.I don't use Google docs, but there just has to be a way to figure out on which account this doc was created, no?Thanks.

The electrolytics are moribund, the pots are essentially six feet under and the mechanical/contact parts are 97% unreliable.It was originally my intent to refurbish the bass's preamp, yet watching 300+ episodes of EEVblog has refreshed my memory of these tasks, so will be replicating the required circuitry from scratch.All because I wandered in to a random YouTube channel one day earlier this year.Thanks again,--Baker

I can do that with any combination of these two, without their possibly even proprietary crap.Even if it somehow managed to work by itself from some sort of speech regnition, you would still need a phone to give it updates, so you might as well just have the app on the phone connect to a regular bluetooth earpeice.

content: FWIW, very likely a spark from 1MV would deliver a peak current of 10kA or more.This is simply physics: as the conducting surfaces discharge, the rate of discharge is defined by stray inductance, while the amount of charge is defined by stray capacitance. The ratio of the two has units of resistance (squared; just as R = V/I, Z = sqrt(L/C)), and that impedance determines the ratio of peak voltage to peak current.The average current from a tiny little charger would be very low indeed; the discharge might last nanoseconds, while the time between discharges is seconds. That's a low duty cycle!As for the tradition, with those stupid things, of hilariously inflating their rated output voltage? Who knows...Tim

Interesting lecture on control theory, I didn't know that the Russians had developed bang bang control theory back in the day, it works but is it ever taught these days, triple integrals in analogue control loops are just asking for problems, two are bad enough but three !! But hey they managed to fix it with double precision fixed point maths at 5 samples per second it's DSP history and should be written up in a book. Rant over. Nice video thanks Homer J.

Odd multimeter behaviour. - Page 1

author_rank: Regular Contributor
timestamp: October 10, 2016, 11:46:28 pm
content: I have a Uni-T UT33D multimeter, a "free gift" with an order from an instrument distributor. It shows odd behaviour on the AC voltage ranges, and I just wondered if I should be looking for a fault, or whether it is just as likely to be a design error. I realise it is not an enormously valuable item, and I don't want to waste time looking at it if there is nothing to repair.What happens is on the AC volts range a small positive voltage gives a reading of about 1.8 times it's value. A negative voltage gives no reading. AC voltages around 50Hz are correct in the absence of DC.Does this sound like a fault?

It may be half-reasonable if you are desperate and know in advance what you measuring, but this situation rarely exist in the real world.I suggest getting a better meter.
