Mine came first. I have looked at S.Petrukhin's design and offered him my advice and what I believe is constructive criticism. I am not running a business (at least not one selling LA probe PCBs) and I don't feel like I'm in competition here. [EDIT] I now realize that you were asking about Hydrabus' design vs S.Petrukhin's. I have a completely unrelated design here. |

I was really helped by the guys in this forum, who studied and gave information about the standard device. @Gandalf_Sr especially helped-he found errors and suggested them to me. @hydrabus upgraded the board and made an independent version. |

Good evening, I just bought a rigol mso5000. I came across this blog. I went to the Chinese site: https://easyeda.com/f33net/digital-probe-rigol-mso5000 I saw an opportunity to purchase components. But I don't see an opportunity to buy the board. I know it's a simple question but can you help me? Simogi |

I answered you on that site: you need to open the PCB in the Editor (see this name button) and select [Fabrication / PCB Fabrication file (PCB)] from the menu there. Then choose when ordering 5 pieces - they will cost $2 plus shipping. |
