Dingoo with different RAM Chips and possibly other innards emerges

By -

Uncanny over at the Spanish GP32 forums has discovered his Dingoo is different inside than mine.  The main difference appears to be a single 4GB NAND chip, and faster RAM chips @ 166mhz, not 133mhz.  Uncanny has also provided an educated guess as to the hardware details of the Dingoo’s acreen, and provided a link to internal pictures of his Dingoo at the bottom of his post (I can’t seem to download them though – I get a "javascript error).

With respect to the hardware of the Dingoo, I have had been to a surprise when abrir the mine today, is that I do not have the same Chips of ram nor of NAND Flash MLC, is more of NAND Flash I only have a single chip, of 4 GB, but not 2 of 2 GB as they are seen in the photos of blog of Scene-Dingoo, are Samsung also but he is not the same. Ram units, if, I have 2 but they are of another manufacturer and after resisting the typical of the Elpida it has been intriguing… you see to me:
Ram memory:
- Total Amount: 32 MIB
- Units: 2x 16 MIB
- Manufacturer: Hynix
- Model (Part Number): HY57V281620FTP-6
- Characteristic (Organization): 128 Mbit (4 Bank x 2M Word x 16 bits Synchronous DRAM)
- Interface: LVTTL
- Maximum Frequency of clock: 166 MHz
- General Info: Databook, Device Operation Documentation, etc.
- Technical Info: Datasheet
Memory NAND Flash:
- Total Amount: 4,13 3,84 GB/GiB
- Units: 1x
- Manufacturer: Samsung
- Model (Part Number): K9LBG08U0M-PCB00 NAND Flash MLC
- General Info: Samsung K9LBG08U0M
The technical difference enters according to datasheets between ram units that appear in the photos Scene-Dingoo, Elpida µPD45128163G5-A75-9JF and those of my Dingoo A320, Hynix HY57V281620FTP-6, is that the maximum frequency of clock of the 133 Elpida is of MHz, whereas the one of the 166 Hynix is of maximum MHz.
Of the NAND chip Flash of Samsung that takes my A320 either I have not found technical information detailed, like datasheet, simply the concise information that it gives Samsung in its Web.
With respect to screen LCD and to the possible one to driver IC ILI925 that uses, when disassembling the Dingoo I have determined the number of the LCD model that comes serigrafiado FTP280P04N-01, I have not obtained to much info on this safe in the Web of the Chinese manufacturer of LCDs Shengbite, concretely in an Excel leaf that can be unloaded its catalogue of LCDs in which the characteristics come from each LCD that makes.
Catalogue Shengbite de LCDs
Concretely model FTP280P04N if it comes, but not like FTP280P04N-01 its FPC, unique the FTP280P04N-00 (registry 523), but by the characteristics seems to agree in all the others, including the ILI9325 like CI controller of the LCD.
These are the gone away and translated data (partly thanks to Google Language Tools):
Screen LCD:
- Model: FTP280P04N
- Model FPC (Flexible Printed Circuit): FPC-FTP280P04N-01
- Length of pliege FPC: 27.80
- Driver IC: ILI9325
- Crystal TFT: THE GIP P4928QC1-1.0
- So large of screen: 2.8 "
- Retroiluminación (Backlight): White, 4 LED Chips in parallel
- Description: In the base of 280C05 for IC and LCD
- I number of pixels: 240RGBx320
- I number of Pins: 37
- Type of Interface (): 16
- Definition of the Pin Nº 1: DB0
- Way and colors of screen (display): 262K TFT/Transmissive
- Perspective of the direction: 12:00
- Dimensions: 69.2 xs 50,0 xs 2.75
- Active area: 57.6 xs 43.2
As I say not it has because to be correct, and plus details (like the one of the type of interface = 16, not to that one talks about), but it seems to agree enough. I have done photos, I will raise account to them of Mediafire soon whoever to see the hardware of a Dingoo A320 different from the one from Scene-Dingoo.
Booboo, if tomorrow you disassemble your Dingoo or you told us if it is looked the interior like mine or to the one of Scene-Dingoo (or to none of the two xD).
Update:
Raised the photos of the hardware of the Dingoo A320, for those who tengais curiosity podeis to unload “pack” of 48 MIB 40 photos from here.

Great detective work!

    Is there anyway to check which one you have (old or new), without actually opening the Dingoo up?

Dingoo A380 Review

By -
Image
The nice folk at isharegifts gracefully sent me a sample Dingoo A380 for review. Having declared my pecuniary interest, in truth though, after playing with this new Dingoo, bribery and graft is strictly unnecessary for its promotion.  IMHO, the product does stand on its own merits.  It remains a testament to the original A320, and its rabid, passionate community (hey, that’s us dudes) that even in 2011, some 3 years after the word “Dingoo” became somewhat a part of the English language,  that it still remains the best Dingoo-type device.  This is because it is still the best supported, thanks to Booboo’s original Dingux, and now OpenDingux.  Dingux means access to emulators and software other than those that came with the original A320’s native uCos firmware.  Dingux allows for ports of games like Doom and Duke Nukem.  Dingux is what turned the A320 from a glorified media player into the device we know and love. It’s still necessary to put Dingux onto a stock standard A320 thoug

With the release of FAT Dingux, it is now possible to install Dingux using only Windows!  As promised, here is The Complete Idiot’s Guide to Installing Dingux – Using Windoze Edition.  Grab the guide here in PDF , zipped here , or here for HTML . 18 October 2009 Update:   The above links will always contain the latest version of this guide . While the guide was written in July 2009, the technique shown in it remains the same as at the update date shown in green.  However, the guide refers to toddler’s or warped flash’s “local.zip” files, and contains links to these files, which are outdated. The links used to point to the A320 freeforums, until the dastardly Dan deleted them ! Grab the latest version of the critical local.zip file, referred to in the guide here: http://boards.dingoonity.org/index.php/topic,32.msg80.html#msg80

The word "Mancala" came from arabic word "naqalah" that means literaly "To move". Dingux-Mancala is the "Awari" variant, and even if the rule of this game is simple, the complexity can be compared to chess Game. The AI is based on the source code of H. Huseby & G.T.

Sources are included, and this package is under the GNU public license, read COPYING.txt file for more information about it. How to play ?

The Dingoo-Scene JXD S7800B (Rockchip 3188 SoC) Android Gaming Console Review

By -
Image
1. Introduction      Since the introduction of the somewhat venerable Yinlips YDPG18, Android handheld gaming devices have been released pretty much continuously, by any number of Chinese manufacturers.      They’re not released with retrogaming in mind however.  Dedicated Android handhelds with physical controls for the consumption of nostalgic childhood memories are simply not in great demand in China, and accordingly, these devices have never been well supported by their makers, as far as the multitude of little tweaks and twerks that the Western retrogamer demands in the quest for ultimate emulation fidelity are concerned.  The view of China based manufacturers seems to be that the physical controls are an adjunct to the primary function of the device – hey, it’s an Android tablet, what else do you want?  Foremost among such frustrations has been OASS: “ornamental analog stick syndrome”, which sadly afflicts many of the devices released to date. What use are any physical cont

Tauon PC-1 review

You should give this a chance. It deserves one. Welcome to the Tauon PC-1. A Tauon is an incredibly  geeky sciency thing , as it happens, and has nothing to do with the  Great Eastern Philosopher . You won't find it for sale anywhere other than on Tauon's website , and on ebay so far as I can see,  and then only if you're a regular visitor of the ebay "vintage computer hardware" category.  It won't even turn up on ebay if you search for the product name: "Tauon PC1"  - you'll just stumble upon it one day, when you're looking for a replacement floppy drive, or a C64.  So, what is it? It's a computer in a dinky little case! Hardware wise, it has: Allwinner H3 Quad Core SOC [1ghz to 1.2ghz/1gb RAM/8GB internal NAND storage] SD slot USB slot,  HDMI and composite out Ethernet Wifi UART (send/receive signals through terminal commands) I2C (drivers aren't ready yet, but promised).   Inside the case - y

Update 4 January 2020: ================================================================== New, much friendlier GUI version released - see this post: https://dingoo-scene.blogspot.com/2020/01/gui-version-of-gadgetmisers-c64-romset.html ================================================================== Hello, friends, it's been awhile.  A happy 2020 to you all. If Santa was kind this year, he may have brought you one of these:   If Santa did, you'll have worked out by now that 64 built-in games, classics though some of them are, is simply  not enough .   Your travels may have led you to this c64 romset:  https://archive.org/details/C64Romset , which contains 17,068 games. If you pop them on a USB stick and slip it into your c64 Maxi/Mini, only the first 256 games will appear.  This is because there is a limit of 256 items per folder that can be displayed on the c64 mini/maxi loader. So you need to split the games into individual folders, each containing n

An interview with the creator of the Tauon PC-1, Volodymyr Mishin

By -
I'll bet you don't roll out of bed and think about making your own PC before breakfast.  Even you do, I bet you haven't actually  shipped . Here's someone who has.   I reached out to the creator of the  Tauon PC-1 , Volodymyr Mishyn who kindly took more than a little time to answer some detailed questions about the PC-1, how it came to be, the challenges of a project like this, his future plans for Tauon OS and what is clearly a very personal labour of love.   Many thanks Volodymyr.   Your  news blog  suggests 30 days to prototype, and 6 months to ship! If that is right, it is very impressive, given the technical and logistical activities that had to occur.  Is there more to this story? I was looking for available options before I started the project. I got myself a couple PI (3B, Zero) OrangePi, C-SKY. And tried to build some kind of educational PC for my kid. Unfortunately, the performance was awful, using Linux was too complicated even for me (I h
