sci.electronics.design compact-flash/ide adapter A compact-flash/ide adapter (SD-CF-IDE-A) from dealextreme.com worked well but only as a master, not as a slave, which is a distinct bother. Anyone know of an ide adapter that works either way, either from dealextreme or another dealer? Hul

The project requires two or more cell phones in a dark container. One of the phones will take a picture with its flash. The other phones will take a picture without flash by holding the equivalent of their shutters open long enough, and with the right timing, to use the flashing phone for illumination. Then each phone in the container will take a turn at taking a picture with a flash, and a...

I'd like to setup a high Q LC to receive a local Radio station probably charging a cap, when the charge is high enough flash an LED. Maybe set the trigger point of an SCR, or could just a zener do it. I don't have LT spice, so please don't post and answer with that.                                 Thanks, Mikek -- This email has been checked for viruses...

I have a Sandisk 32G USB flash drive that someone has given me in the hope that I might be able to salvage some data off it. Looks like it was in a laptop and jammed against a wall, resulting in broken solder joints. My PC wasn't detecting it when it was plugged in at all. I cut the drive open and attempted to re-seat the pins and then reflow the solder using a heat gun on a low setti...

I have a project in mind using small Flash RAM and a cheap CPU to substitute for the old TTL level CMOS RAM used on arcade games. This has come up because the NVRAM that is currently being used is getting hard to find at prices under $7 to $9USD. Something like the M25P05-AVMN6P (512k or 64K x 8) or similar chips are $0.20 in single quantities. The size of CMOS RAM we are replacing ...

Anyone have any pointers to SPICE models for Xenon flash tubes? Or at least data sheets that have the I-V characteristics described or graphed? (This is for a hobby project involving discarded photoflash units, a 19 year old kid, and various web pages on building coil guns, by the way). Thanks in advance. -- My liberal friends think I'm a conservative kook. My conservative friends...

We're planning a new universal boot loader for a family of ST processors. The uP would host the loader in a bit of local flash and read an outboard serial flash to get the specific application code and one or more FPGA configurations. So, how many config bits might there be for a modern mid-range FPGA doing a moderately complex application? I think we could enable compression too. ...

Hi I have been looking into the GigaDevice GD32 Cortex M3 microcontroller It has a REALLY nice price performance ratio So I dug a little deeper, and found that they do not integrate the flash and microcontroller on the same die as a normal microcontroller, but instead they use a single die variant of logic and core, and glues a serial flash on top of that Link to picture: h

I thought I would give Amazon a try and see if the USB flash drives sold there are any better than the crap sold on eBay. Well, it seems not. I picked a drive in a metal case to stand up to a bit of abuse and order two in order to get the free shipping. Amazon makes it hard to get the free shipping without signing up for their master plan that's over $100 a year now. But eventua

Over 10 years ago I started a website ( www.fourier-series.com)in which I built interactive flash programs to teach various engineering concepts. I Initially designed these programs to personally understand DSP and then to pass along what I learned to others****. These topics were fourier series, discrete fourier series, fourier transforms filtering I/Q modulation and also some RF s

I need to send 40GB of photos to several people. My upload speed is .230 MB/s. It seems to me my best bet is to mail them a flash drive. Any tips on mailing them 1st class mail? Any problems mailing them to Mexico and Canada? I live in Texas. Nothing illegal just common family type images. Thanks

Does anybody know of one? I'd like to digitize 6 bits or so, really fast. Most fast ADCs take 3 or 4 clocks to process the data. Even 4 bits might work. Classic "flash" ADCs were fast, but needed 2^N comparators.

Where do they connect auto immobilizer? Ignition wire is simply, but too simple and obviously easy to by-pass. For my old Ford, i disable it with the crankshaft sensor, since it would not start without it. I am using Intel Edison or Raspberry Pi to control an relay. Both can do the job. Edison is better because of the small size and embedded flash; However, it is also worse

Sorry to ask this rather obscure Q but ST "engineering" is not really contactable via any normal means... It looks like a superset in every way, comparing the data sheets. They even made the 2MB of flash in the 437 as two 1MB banks, which rather defeats the point of having 2MB unless you can generate "large model" code like one used to do with the old Z80 etc if wanting to have > 64k of

I want to concoct a trigger to fire my camera when there's lightning in the area of where the camera is pointed. I do not want one of the RF burst detectors, as I don't care about lightning that's not in front of the camera itself. I'm thinking about some sort of photodiode mounted in a housing peeping through the viewfinder for actual flash detection. Past that, I'm not too sure of wha...

Hello, I used WinToUSB to install Windows 10 on a 128 USB/Flash stick. Windows 10 ISO used was: en_windows_10_core_10240_x64_dvd.iso (UnOfficial RTM) During boot windows 10 hangs and a blue windows logo can be seen. Nothing else happens. I waited for 45 mins or so before resetting this PC. I then proceeded to complete the installation on a Toshiba L670 laptop. And it instal...

This is an idea for an experiment I may or may not do. The background: There have been reported seasonal variations in radioactive decay in the past. Now If I took a simple tritium light, and a good quality photo-diode, put both in a light proof box, and logged that with a 10 bit PIC ADC with a decent Vref for say a year to FLASH, say 1 sample / hour, run the whole thing of some battery. ...

I modestly note that I predicted that the mainstream news industry would soon switch from obsessing on viruses back to obsessing on climate, until they can come up with something better. I've seen the shift already, but now it's getting official. https://wattsupwiththat.com/2020/04/17/more-than-400-news-outlets-partner-with-a-project-seeking -media-to-beef-up-climate-coverage-amid-pande
