I bought EOS3 BGA on CrowdSupply and as I started to work on my board. After some time I have discovered that it would be hard to make it at low price.If I would do it correctly I would need to use small vias, probably buried vias so for few boards that did not make sense to me…But as I still wanted... »
At start of the year NLnet decided to sponsor development of modular FPGA, for now we will call it ULX4M as first version should have everything that ULX3S already has. https://radiona.org/ulx3s/ Goal is to make board modular and add more peripherals. We are specially interested in adding fast SerDe... »
Milestone 2 •Start to work on first daughter board that will have selected connectorsFor start I first needed to completly dissasemble ULX3S.I did that in a way of spliting into modules. https://www.linkedin.com/posts/goran-mahovlic_ulx3s-innovation-activity-6823611763443933184-4n5O Once I had every... »
At start of the year NLnet decided to sponsor development of modular FPGA, for now we will call it ULX4M as first version should have everything that ULX3S already has. Later we want to add more peripherals, and we are specially interested in adding fast peripherals that are now missing on ULX3S. Al... »
Paula: Blender: We imported the board from KiCad in various formats into Blender in order to get the most customized and simple object for editing or manipulation. The first problems were related to the excess geometry that occurs when importing .stl and .obj format. This problem needs to be solved ... »
At some point I have ordered microscope. I wanted one that would have Simul-Focal Stereo with HDMI out that would allow me to work on it looking on eye peaces while recording or streaming at the same time. But it was impossible to get good focus at eye-peace and on the HDMI at the same time. I could... »
For long time I wanted to have backup of lemilica, as I had lots of problems with site remaining up. So few days ago I decided to try docker containers. Create wordpress.yml with your favorite editor Copy code bellow to the file. If you do not need phpadmin you can remove those lines Change your_MYS... »
Using ttnmapper to map nodes is often good start for mapping. But ttnmapper is still closed source and you can only use it for showing coverage of TTN gateways. If you have your own infrastructure you need some other way to visualize your GPS data. So first you need to have your data received in NOD... »
And all of this started when EMARD ordered one Mini Fabrikator V2 For a some time I have this small printer I have buy it from EMARD that already applied his fixes on it. When you get printer it usually comes partially disassembled with missing or unscrewed bolts and screws. When you fix tha... »
We had some issues loading file to a new board. But board was detected so that was good start. After I told Emard I have problem uploading file he fixed JTAG tool. And I could screen to the board. Now I could load sample code from arduino :) Galaga Fractals Just default frame buffer. Some fancy text... »
Checking if all pins of FPGA are connected. Sorting parts. More sorting. Soldering FTDI. Soldering capacitors. Soldering power circuits. Random soldering Random soldering. Almost done. Near end. Problem!!! Chip was placed wrong. Fixing chip orientation. I still had problems, and solve it on this pic... »
Tnx to EMARD new FPGA board is in town ;) https://github.com/emard/ulx3s We have tested and almost all examples are already working. But there is still many things to try. One thing for checking is will examples work on smaller FPGA. And we need to do that manually. Bare FPGA board Just another look... »

@Home I had Nextion LCD It is having some bad software that is working on windows only I was not able to find a way to use interrupt on some pins. So I was thinking about uploading my code on STM32 to test it out. But Nextion does not provide factory flash for this display so if I change firmware I ... »
I have ordered some 868MHz modules from internet and just searched a way to use it. At first look https://ukhas.net/ looked nice so I decided to test it :) If you get lost there is nice sitemap so you can find what you are looking… https://ukhas.net/wiki/dbrooke_nodes:dbpg?do=index So it is ti... »

I saw that Ai Thinker that developed ESP8266 has some new modules, and after a bit of search found cheap GSM development board http://www.ebay.com/itm/152255901336?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT I have found all documentations and source code for 8051 chip. I have te... »
