Title: Watch out for the clones!
Post by: digistump on May 22, 2013, 01:09:37 am
The first Digispark clones have been spotted:


Of course the Digispark is OSHW - so nothing legally wrong with this first one:



http://item.taobao.com/item.htm?spm=2013.1.0.156.FkcdAS&scm=1007.77.0.0&id=20373031373&pvid=c914065f-196a-4fef-9da7-d9640d015d52&ad_id=&am_id=&cm_id=&pm_id= (http://item.taobao.com/item.htm?spm=2013.1.0.156.FkcdAS&scm=1007.77.0.0&id=20373031373&pvid=c914065f-196a-4fef-9da7-d9640d015d52&ad_id=&am_id=&cm_id=&pm_id=)


But we sure hope you'll agree that our soldering and finishing comes out a bit nicer!




This one seems to be violating our license on the Digispark name and using our photos (not that we'd have much luck challenging a product on taobao - we won't try):


http://item.taobao.com/item.htm?spm=a230r.1.14.1.PsNnMb&id=20137319692 (http://item.taobao.com/item.htm?spm=a230r.1.14.1.PsNnMb&id=20137319692)


Strange thing about that one is that they don't show any photos of their actual product - if it didn't cost so much ($25!) we'd buy one just to check it out.


Have you seen any clones? We'd like to see them! We feel honored that people feel it is worth making clones/fakes!

Woo! You've hit the big time! That first one looks to be about $6.20. It's crazy how much of a difference labour and shipping prices in china can make.

Maybe that second expensive one isn't a clone? Maybe they're just reselling it? There is certainly a market for buying things in one country and selling them in another with a markup, because language barriers would make it difficult for some chinese to use the digistump shop directly I'd think? That's exactly what a lot of the hong kong and singapore based ebay sellers I buy from are doing - just giving me an english language interface and product description so I can buy from china.


I hope we see some more innovative clones soon. Really, I'm hoping the Adafruit Gemma ends up being digispark compatible. It'd be neat for someone to make a wearable-optimised digispark compatible, and Adafruit create and maintain so many Arduino libraries, it'd be great to have them focus some internal resources on digispark compatibility so I wouldn't have to. :P ^_^

That's very possible though I found a message board in chinese where someone says it is a clone and links to it - but who knows!

I'd like to see this too - solarbotics took the first step - their firefly has the header spots for connecting shields - if only whatever clones come out use the same connection layout then we'd really have something!

Looks like taobao also sells the Pebble watch, the Chargecard USB cable, and a few other Kickstarter products. I'm guessing that they're buying and reselling the real deals.

Interesting that for US delivery, all of these clones ($15-20 with 'free' shipping) are more expensive than the original chip ($8.95 + $3 s/h if you go through digistump.com, $8.95 + $4 s/h if you go through tindie.com, , or if you live near a microcenter, $9.95 + tax).  And of course you have the usual China shipping times.  Usually clones are supposed to be cheaper than the original.

I don't understand that business model either.
Especially compared with the usual chinese mini-arduinos sold in the same platform: http://www.aliexpress.com/item/5pcs-lot-Pro-Mini-328-Mini-ATMEGA328-5V-16MHz-Free-Shipping-Dropshippin/1221671702.html

Maybe they have taken this offer from the german ebay: http://www.ebay.de/itm/DigiSpark-das-mini-Arduino-kompatible-USB-Entwickler-Board-inkl-Header-und-Pins-/281070562362?pt=Wissenschaftliche_Ger%C3%A4te&hash=item41711c6c3a#ht_4390wt_1399 as baseline for their calculation. The seller offers the Digispark for 19,90 Euro ... that's based on current FX rate more than 27 USD ... ok ... including 19% VAT ... but maybe they haven't read that  ::) based on that price, the clones are cheap  :)

What me also impress: the german ebay site shows 16 Digisparks already sold for that price ... this brings me to the conclusion that we sell it too cheap :)
Title: Re: Watch out for the clones!
Post by: digistump on October 29, 2013, 10:44:03 am
Here too: http://www.goodluckbuy.com/cjmcu-digispark-kickstarter-micro-arduino-general-usb-development-board.html

I've seen almost no clones that are cheaper... so strange.

@cboden - that seller bought them through our Kickstarter, so they paid full price and then added some major mark up. We see even the $20 chinese clones selling well, makes you wonder if people ever google "Digispark" - given that most the buyers are in the US!

I noticed this chip in the new items list at tindie.com today.  It uses the digispark form factor so it can use the shields, etc. But instead of having the USB type A slot, it has interfaces for using ISP programmers.  You can also pop off the ATtiny85 out of the dip-8 socket.  I hope the guy has dotted his i's and crossed his t's and things are legal as far as digistump is concerned.

@Michael: This guy posted some of his work already himself in this thread, he is active here as well. 
That shield looks really nice, compared to what I have build (http://digistump.com/wiki/digispark/tutorials/programming)

@Bobricius: compliments!

Title: Re: Watch out for the clones!
Post by: digistump on October 29, 2013, 02:05:24 pm
Yep Bobricius makes some cool Digispark compatible stuff - it's good with us because he doesn't call any of it a Digispark.Though I guess this newest listing would preferably read "Digispark shield compatible" - but I don't think the omission of "compatible" was on purpose. All and all Bobricius' stuff is exactly what we hope for with open source derivatives/compatible works.
Title: Re: Watch out for the clones!
Post by: MichaelMeissner on October 29, 2013, 04:09:58 pm
Yep, I didn't mean to imply I thought it was a problematical clone.  From the description, I could tell it wasn't a clone, but an enhancement, and as I look at a 2nd or 3rd time, it is clear it is meant to add to the digispark ecosphere.

Interesting from an eyesore became adapter which is just a waste adapter between USBASP and Picoduino that is a true clone. Yes I admit. Overpriced? Maybe, but there's almost a year of work, four generations of boards. None pick & place only hours tweezers and handicrafts. I sell on ebay or tindie.
Erik is a true genius, invents that is possible sell small board of several components at a price that sells Chinese Arduino uno, and I am very grateful to him, because the design of the tiny85 is unique, no crystals, only the most necessary components and all pins are used. Although I decided to let reset enabled. It is more serviceable and programmable via usbasp.

My work, of course, again I'm not happy with.

... power led and reset button is on back side
http://www.sardravce.sk/bobor/pico1.jpg

... great combination tiny85, rgb led, ds1307, on back side 24c512 and battery holder, switch trasistor for relay, in next generation will have output on connector, now is only on test point :(
http://www.sardravce.sk/bobor/pico2.jpg

... and this is only tiny85 based small wav player, of course now discontinued, redesigned and new wersion will realy great
http://www.sardravce.sk/bobor/wav.jpg
http://www.sardravce.sk/bobor/wav2.jpg

I am very sad that I have no time for programming, only the PCB design. But promises to bring to this community a lot of inventive ideas. I plan on talking watches, eeprom wav player, oled display, step motor driver, RTTTL player and more. But at present spend time with my two young children somewhere will take away the mail envelope when something sells and I buy some extra components or PCBs.
I not get rich on it, just earning some money so I can develops new things.

This one is definitely a respectful derivative - see blog which gives us credit and my comments: http://olimex.wordpress.com/2013/10/23/look-mom-i-can-shrink-arduino-even-more-and-it-cost-only-eur-4-00/

It's cool they are using the Digispark version of the IDE - that seems to be gaining lots of traction, perhaps I should add Trinket support to it too!

Now that is cheeky, produce a clone and use someone Else's software.

Well the software is Open Source, so that's sort of the point of that, letting anyone use it.  It is however a bit cheeky to point at someone else's website, rather than hosting it yourself.  There are ways to configure a webserver to look at the referer page, and return different content depending on that.  I haven't looked at it, but it's quite possible that clicking on a link in a PDF may return to the name of the PDF to the server as the referer, in which case you could trivially return something "interesting" or even vaguely malicious (like a download of a large randomly filled file).

Whilst having a real USB connector on that board, rather than relying on a PCB connector is nice, I don't quite see why they've limited that board to only four IO lines, rather than all six.  Having an eight way header, rather than the six way one they've used, wouldn't take up much more space, but would increase the number of available IO lines by 50%.

I just spotted this:

https://www.tindie.com/products/BBTech/attiny85-usb-development-tool-board/

If I am not mistaken, it is rather a Trinket clone. But it comes with micronucleus. It even has the newest version, quite industrious!

Edit: It has optional pull-up resistors for I2C. This is new, isn't it?

Hi cpldcpu,

I just spotted your clone: http://cpldcpu.wordpress.com/2014/04/25/the-nanite-85/

That really looks like as the crown of the evolution of the attiny-boards!  Compliments!

They actually are not violating anything. If you check the top, they clearly labeled it as the Digispark on kickstarter. If anything, they are reselling them, not sure if that violates anything however.
