bsittler Posted October 21, 2020 Share Posted October 21, 2020 Received today (hat and case), assembled, and now put to work reading my small Lynx cart collection after which I intend to leave the original carts packed away and play from the RetroHQ flash cart. This is a great little device with quite usable software and the stylish case is a nice touch too I'm hoping whitelynx.fi will again sell the PCB's at some point to make dedicated patched/homebrew game carts too, for those situations where the RetroHQ flash cart is overkill but rewriting is needed occasionally 1 Link to comment Share on other sites More sharing options...
+karri Posted October 21, 2020 Share Posted October 21, 2020 Actually I have lots of carts available. But due to 5 month delays in post I decided to wait over the US elections and try again later to see if the post is still broken. If you are in the EU just drop me a nessage. 1 Link to comment Share on other sites More sharing options...
Igor Posted October 28, 2020 Author Share Posted October 28, 2020 I'm surprised how quickly parcels are arriving now that I started to ship again. Not as fast as pre-COVID but around 3 weeks to US is not bad (used to be 2 weeks). I've made a batch of 5 using my last PCBs, unfortunately one of them was DOA, seems that one of the IO expander chips is broken. I'll be updating the design of the PCB with the new logo and ordering a new batch so I can fulfil all of the outstanding orders. Link to comment Share on other sites More sharing options...
Nop90 Posted October 28, 2020 Share Posted October 28, 2020 With a new logo, the previous pieces will become vintage and grew in price ?. With the price drop of the RPI3 decided to buy one to use with my second programmer hat and the case you designed: Can't wait to check the new writing speed respect to the RPI Zero! 1 1 Link to comment Share on other sites More sharing options...
Fadest Posted October 28, 2020 Share Posted October 28, 2020 Around 2 minutes for a 256kb ROM with a Pi3 in turbo mode. This is quite good. Wonder how much it would take with a Pi4 as they now have the basis same price than Pi3. Link to comment Share on other sites More sharing options...
+karri Posted October 28, 2020 Share Posted October 28, 2020 The Pi4 is a beast. It is about 3 times faster then the Pi3. The only "problem" is that I got completely obscessed with old Amiga pinball titles. The Pi4 running dosbox-staging with some pinhack produced absolutely amazing virtual pinball tables. I just got 253 million points in Babewatch. With USB MAME buttons and the volume cranked up to max it gives some cool vibes. Link to comment Share on other sites More sharing options...
Igor Posted October 28, 2020 Author Share Posted October 28, 2020 I have a Pi4 here but haven't tested it out yet, will need to do that. I still think that the writing and reading speeds can be improved in software, just need time to work on it. Link to comment Share on other sites More sharing options...
AltRN8 Posted October 29, 2020 Share Posted October 29, 2020 Is it possible to get on the list still? Link to comment Share on other sites More sharing options...

I'm in the process of confirming that I can get more components so once that's confirmed I'll have a proper announcement of new orders. Also @karri opened up his store for cart PCB sales if you want to order those they are here - http://www.whitelynx.fi/shop/#!/10-Cart-PCB-boards/p/56645940/category=0 Link to comment Share on other sites More sharing options...
AltRN8 Posted November 3, 2020 Share Posted November 3, 2020 Thanks for the pointer to the blank pcbs. I’ve just submitted an order for ten. Thanks also for adding me to the list. 1 Link to comment Share on other sites More sharing options...
Jsloubet Posted November 14, 2020 Share Posted November 14, 2020 Hi Igor, Could you please add me to the list ? Many thanks Link to comment Share on other sites More sharing options...
Igor Posted November 15, 2020 Author Share Posted November 15, 2020 Will do, it will be for a new revision of the board too, very excited to put these together. Hardware wise it hasn't changed but it's now red and I've tweaked some of the traces and pads to make it easier to assemble. Also will not be using the usual quality control stickers any more because there's a white rectangle on the PCB where I can write quality control info directly to the PCB Link to comment Share on other sites More sharing options...
+karri Posted November 15, 2020 Share Posted November 15, 2020 I just had a small inventory and found out that I have less than 50 panels left. (500 carts) For the next set of panels I could that the same approch as I have now. Or I could make it a bit fancier. There is a possibility to have hard gold fingers for the connector and perhaps use black pcb's. The price would increase a bit. And so would the durability. Another possibility would be to order a new batch now so that I could stock both types. Any comments? Link to comment Share on other sites More sharing options...

A little stock with larger EEPROMs. I'm going to change the chip on some of the carts I have for a project of mine that will require a large save. With the increasing lynx coding activity, sooner or later other devs will explore this possibility. 1 Link to comment Share on other sites More sharing options...
+karri Posted November 15, 2020 Share Posted November 15, 2020 Swapping the chip to a larger one is simple with a littke hot air. Are you interested in 2k or 64k? Link to comment Share on other sites More sharing options...
Nop90 Posted November 15, 2020 Share Posted November 15, 2020 don't know yet. Have to check the 64K chip price. Link to comment Share on other sites More sharing options...

Sounds like a RPG is coming I dont mind having the exact same PCB in the future, but depends what would be the cost for black pcb, and also if the gold connection really makes a difference.

But we need to write a driver for it first. Edit: It is just 0.7€ each. And it is not 64k - just 32k bytes. You could also use 24AA512 series that is 64k. It is around €1.10 Or 24AA128 series that is 16k. It would just cost €0.50 Link to comment Share on other sites More sharing options...

+karri Posted November 15, 2020 Share Posted November 15, 2020 I should have a few boards with these chips already soldered in. If I find them I could send it to you for trying them out. For free Link to comment Share on other sites More sharing options...
Nop90 Posted November 15, 2020 Share Posted November 15, 2020 Don't worry, at the moment I'm busy with a lot of other project. If I need them I'll make you know. Link to comment Share on other sites More sharing options...

Same here. I was just trying to trick you to write the drivers. ? I believe the easiest approach would be to write it in C. Perhaps it could be a block device that reads/writes 32 bytes at a time. 1 Link to comment Share on other sites More sharing options...

EDIT: the protocol seems very easy (easier and faster than the other chip), will try to modify the existing protocol to work on this EEPROM chip. The good thing is that the protocol is exacly the same for all the 24AAXXX chips (up to 512 bits, the 24AA1025 has a little difference).

Igor Posted November 16, 2020 Author Share Posted November 16, 2020 I think ENIG fingers would be good because they won't damage the cart connectors. In terms of colour...it doesn't cost any extra to do colours these days, not at PCBway anyway. I'm looking at redesigning the programmer completely next year, to make it easier to use, will see how much time I will get with a baby around!
