DJ Equipment, why time coded vynil?  - Page 1

content: Hello mates,recently i'm getting interested in DJ (disc jockey) stuff...In the past, djs used to mix with vinyls over turntables and a very simple mixer (two channels, 3 band eq, fader and volume control).Then the serato company came the time coded vinyl, basically a vinyl with a 1Khz tone, the pick-up gets this signal to a sound card and a very smart software implements a rotary encoder based on frequency, phase and etc...I understand DJs like this setup because you get all the touch and feel of vinyl, the torque from the motor and the resources of the modern DJ software.The expensive DJ controllers, which are not turntables, may have jog wheels with motors, for torque feeling, while the majority are just a rotary encoder under the plate.The problem with the time coded vinyl is, of course, the pick-up transducer does not like to much bass or vibration, which mess the setup.Them, I cant understand why not to get a traditional turntable and add a encoder under the plate, making a massive jog wheel without the pick-up and their problems.Anyway, pioneer, stanton, technics, numark and others keep launching new turntables.Is this just marketing stuff or I'm missing something here?

content: When you move the record, you're not moving the much heavier turntable, usually you have a slippery felt or neoprene mat called a "slipmat" between the turntable and record, in contrast to a HIFI player where you have a rubber mat.The timecoded vinyl came into play about 10-15 years ago when there was a huge install base of people with vinyl record players, and everyone wanted to play their MP3s while still looking cool.At this time there were a lot of computer-connected or standalone dj controllers emerging, but the encoders and feel was kinda crappy in the beginning.There were some full size vinyl record players, that also featured a built in cd player and USB for MP3s that I do believe you could use the turntable on to control CD/MP3 playback, not sure how they did it, perhaps with some split axle where you clamp the record to the inner axle and the outer one is driving the turntable.There might be some more reasons, and you can try googling them. Today the "feel" on digital jogs is just as good, but of course handling real records is more fun =)

A pricey scope? etc?For me, it would be the decision to finally spin my own board for a personal project instead of resorting to my usual perf-board wire jumble. I went with JLCPCB based on price so hopefully I dont regret this haha. To be frank, I've spun quite a few boards for work but I have never "allowed" myself to spin a board for a simple one-off home project. This time, I felt too lazy to cut, strip and solder a bunch of wires and just jumped in on a PCB order. The funny part is now I want to take on more complex projects at home because the anxiety of manually wiring it is fading. I love hand populating pcb's (except qfn/bga's), it's dealing with the wiring that gets me.

As much as I like to support domestic manufacturing, Chinese board houses have made it feasible to get boards for all sorts of random hobby projects. I still etch my own when I'm in a hurry but that's rare these days.

The video clearly says it’s RG-58 cable, which is perhaps the most common cable for 50 ohm lab use. (Cable TV uses 75 ohm cable, such as RG-59. And the F connector sucks.) SMA is a common RF connector. But even more generally... you make a particular cable assembly because, you know, you need it to connect other things. So you choose the connector types that will mate to the devices you’re connecting. Mounting an F connector does you no good if the device has an SMA jack...

content: The pinouts look mostly the same, the main differences are a couple of NC pins on the CM108B which had GPIO finction before and the EEPROM control lines look to be swapped.If you wanted to spoend a little time working it out there are pinouts in the CM108 and CM108B datasheets but I'd also order up a cheap CM108B USB sounds card from eBay and draw out the schematic from that, they're really not complex (I've got quite a few)

Laptop Screens. A few interesting Notes!! - Page 1

content: I've changed countless screens for people. (VERY easy job!). I thought I would point out somethingto assist with ordering, & prices... Here's an example from this week, for a Toshiba Satellite Pro L50-A.To order a screen on say Ebay, you 'normally' at least need the LAPTOP 'Part/Model-No.' too, which inthis case, was a 'PSKK7A-002002'. Now, that found results, and the cheapest in the listing was $100,from Interstate, (I live in Australia), including postage, and a ($4) discount for me, as a past user.However!! Searching in THAT way, (via specification of a particular Brand/Model of Laptop), LIMITS theresults to certain Vendors that have 'advertised' that way, which includes THEIR markup from suppliers.Instead, FIRST pull the screen apart... (you are going to have to anyway!!), and note down theactual SCREEN part-number from who ever made/supplied it, and search for THAT alone !In the 'above' case, it's a 'NT156WHM-N10' Screen. Searches on THAT, revealed these 2 among many...$77 from Victoria Australia. Plus $19.25 postage. (Even though I'm in Aust.), and...$67 from China. Free Postage ! (Still only 1 to 2 weeks delivery).Much better way to search.Note-2...We all (?) have Laptops that are stuffed/beyond repair, but this time the SCREENS are Ok !!!Try re-purposing them!, as a secondary screen for your Laptop or PC. Often they are hi-reswide screens, at least 1080p, and can be utilized for next to nothingAll it needs is a 'Control Board' for example, specifically made for the screen, for $20-$30...https://www.ebay.com/itm/HDMI-VGA-DVI-LCD-Control-Board-For-LP156WF4-SLB1-LP156WF4-SLBA-1920x1080-Screen/273701366278?hash=item3fb9df6a06:g:JYMAAOSwFoNcSsa0&frcectupt=trueThey include anything up to HDMI for their input.Here's an old Youtube link, for something like this!!!

It's my speculation, we need to check logs in the next weeks to see if confirmed.I think it's really interesting

I was emulating this using MAME/MESS, download all the various chip ROM files and run a Commodore C64 machine or Vic20 or PET even. Then you load up the tapes (using a "LOAD" type command, or whatever) and it would read in the file as if it was a tape and let you run the programs.Quite a bit of stuff there. However to get it to run on real hardware you will need to convert the tapes BACK to some kind of audio file I presume, and record it on a tape somehow, or figure out how to transfer it directly via audio output from your computer to the input of the VIC20 cassette mechanism.
Why is no one working with Allwinner F-Series processors? - Page 1
Forum section: electronics / general

author: soFPG
author_rank: Frequent Contributor
timestamp: March 27, 2019, 08:47:33 pm
content: The question of this topic is already in the header but I try to describe my intention a little bit:I read about some projects which use the Allwinner V3s or A13, but no one really uses the F-Series processors, linux-sunxi even say, that they don't support it (http://linux-sunxi.org/Allwinner_SoC_Family), which is unfortunate.In my opinion these processors are a great starting point for people who want to get into developing a "System on Chip" - PCB but don't want to deal with high speed interfaces and BGA routing / soldering like one has to with DDR2/DDR3.For example, the F1C500 (http://www.allwinnertech.com/index.php?c=product&a=index&id=27) has enough hardware on-board (UART, SPI, I2C), is available for 3$ at aliexpress and probably has more processing power than any other microcontroller (like M7 etc.). It has a SDR-RAM interface, there are plenty of TSSOP SDR-RAM chips out there - so that's nice.It is also comes in a solderable QFP package.The only problem I have at the moment: There is only a very short user-manual but no reference-manual (like there is for the V3s) available. So I would like to ask kindly, if anyone here has access to a more detailed description of the processor?Edit: I know, they are really old chips but still available and not too complex hardware (in my opinion). ARM9 should also support JTAG. I also know, that a closed-source RTOS from Allwinner runs on those chips but I don't think it is available to the public - at least I didn't find anything source-code related.
