I don't do anything with immersion so no, I haven't tested them in that environment.

Sorry to hear about the problem Salvador. There's nothing on the 1397 ASIC that needs to be flashed, so I assume you mean the Bitaxe controller. Your best bet for getting help with flashing the Bitaxe is to join the Open Source Miners United discord server - discord.gg/vpE3T72f Check out the Bitaxe section.

man, you are going back through the old stuff. That's good if you want to see complete chip replacements but it's slow because I didn't edit the video as much. I think I shared the link in a later video, but here you go - docs.google.com/spreadsheets/d/1OXT9q3r96rkIFR30j3kNryT5n81lID_wapaY3p7A1Gk/edit?usp=sharing. Just a warning, it's not 100% complete and there may be errors.

@iagmr Thanks so much! Yeah, I just can't get enough. Man, those stupid tiny resistors are going to be the death of me! I'm not sure where or how I'm losing them here and there. I don't suppose you would be willing to take a few questions from me. If not, I do understand. We are all busy. But if so, how might I get in touch with you?

@@MakerMike-bx5ms check the about/description of my channel and you'll find an email to contact me. Hint: it starts with crypto :)

I have an Amscope 745 scope (amzn.to/4aVBt7i) alongwith the their LED ring (amzn.to/3VYGlUE) which I had to modify a little to relocate the power connection. This is the Articulating Stand I have (amzn.to/3U2pRbJ) however I'm not happy with it because of how much vibration it transmits. You might want to consider this heavier stand (amzn.to/3U2pRbJ) if you have the bench top space. I like the stereo microscope because it gives me some depth which seems lacking when I watch on the screen.

@iagmr Awesone! Thank you very much! Are you still making videos? I see you haven't made any in some time. I'm really interested in this content. You seem one of very few that provide it. And I still can't change a chip successfully yet. I have tried some different techniques, but I have not been successful yet. I am receiving a tester from Thanos and a winning fixture today. I hope this is the missing piece. I would love to watch more of your videos. Please make more. Thanks very much for all you do!!

@@MakerMike-bx5ms thanks man! I've been so busy with building/using CNC machines and 3d printers lately. I really need to get back to work on the miners. I believe we are going to $200K BTC in this next run.

@iagmr I was just rereading this comment and what you recommend for articulating the arm, and the links are the same and take me to the same item. So, I am not really clear on what you have now versus what you may additionally recommend.

Hey bro , which tester are you using , which is useful for all miners ? Iam from India and am also into it , how can we connect to share knowledge ? What is your whatsapp number ?

Not yet.

​@@iagmrhello sir, how can I connect you , I want to learn ASIC repair , please guide ?

@@AshishKumar-uu3lw my contact info is the about of this channel. However, if you want to learn to repair ASICs check out my other videos on the channel, join the various Discord groups on the matter and look for ASIC repair schools. As I pointed out in one of my videos, be careful with technical schools that teach lots of drifferent Trades courses. Ideally you want to learn from a company that actually does repairs.

@@iagmr sir I want to learn from you, how can I learn from you ? please guide me ?

@@AshishKumar-uu3lw that is a great compliment sir. I don't offer an direct teaching/training for ASIC repair to individuals. Your best bet is to watch the other videos on this channel. Good luck in your journey!

Check the about section of the channel for my email contact info. Waiting another year or so until BTC is over $100k might be a smart move 😉. It sure was in the last bull run with the L3s

Try this link - discord.gg/YUCUuPXAZF I'm not sure why the links keep breaking when discord says "your invite like will never expire" 🤷‍♂️

@@iagmr Sorry I meant the bitaxe discord

@@Arek_R. doh! that would make sense as you were talking about bitaxe. Sorry about that. Try this link - discord.gg/S4nYrmja . I'll fix it in the description as well. Sorry I've been distracted with CNC routers and 3d printers lately

I never saw any improvements.

This test socket won't do that. I'm not sure if the RU Asic Tester that I reviewed will do that or not.

Is there another good way to test BM1362AK chips?

@@eslamsaad2551 stasic tester can overclock these chips on a hash test at a frequency of 500Mhz

Thank you. I sure didn't realize what all was involved until I started doing them. If you are working at a large enough scale, there's some mechanical automation that can be built, but that takes time and money which must be recovered in the upgrade price as well.

To be honest I'm certain what the degree of conductitivy is on the S19s but I've had really good luck with the green thermal paste from Thanos (tiny.one/S17GreenPaste)

Thanks Mark! I use these mokose cameras with OBS on my channel. I've tried the Hayear microscope software when trying to measure parts on a circuit board but it didn't really work for me.

@@iagmr New subscriber to your channel. I just downloaded (not installed yet) OBS. I am an old man, but new to video, software, and streaming. I hope to connect a camera to my Vaughnlive channel and stream live. Sadly, I just purchased a Hayear camera a week before I saw your video. Guess I'll be buying a different one soon. I have an refurbished Olympus BH2 (trinocular) coming in the mail soon. Your channel is a great resource and I thank you for taking the time and effort to share your info with others. All the best.

Thank you, that means the world to me. Here's a fresh link from the discord app for the Antminer Repair channel - discord.gg/JH8yfvZFxE

I haven't run HIVE in a while. Prior to the domain shutting down do you see any weak chips in the domain? There are a number of things it could be including a weak LDO. But I'd start with replacing the lowest performing chip in the domain. You might also ask on the Antminer Repair Discord channel. The link is in description.

Some of my earlier videos show me doing the entire process in real time especially the live streams. Since it takes me several minutes for each chip I started compressing that footage. The basic process I follow is: 1. Remove the chip 2. remove the solder on the pads with solder wick and flux (don't press too hard) 3. re-tin the pads with leaded solder (use plenty of flux) 4. install new/recycled chip that has already been tinned. (more flux) Hope that helps.

@iagmr this is really helpful thank you so much ❤️❤️

I tried a couple of different programs, however I was mainly using OBS and the Hayear microscope software.

@@iagmr Thanks. I have an “Eakins” 1080P camera that reports itself as “‘H1600” when plugged into USB. The Hayear software shows “No Camera”. I wondered whether this camera worked with that software.

@@cyberia55 that's a good question. Now that you mention it, I never saw any of my other web cams except the Mokose and Hayear in the Hayear app. I think the Mokose were present because they use the same chip set.

@@iagmr My apologies, I didn’t phrase my response clearly. I wondered whether the Mokose worked with Hayear software; you confirmed this. I already know that this “Eakins” decal’ed 1080P camera does not work with Hayear software. When I saw “H1600” reported by the camera over USB, I assumed it was “H” for “Hayear”. When it then didn’t show up in the Hayear software (“no camera”) I went crazy looking for some menu item to “connect” to the camera. Eventually I resigned myself to the fact that Hayear software only recognizes their own camera, and “‘H1600” isn’t one of them. Hayear software is the same software used by AmScope (I tried them both, they appear identical), they just change the name. Also, every camera I’ve seen reviewed on KZbin ignores the dozens of adjustments and features available in this Hayear/AmScope software. Is there a camera that responds to *every* feature? If not, it makes one wonder why they would bother to develop and include those features in the app. 🤔 My original camera was an AmScope MD800E, but there are no drivers available for Windows 10. I contacted AmScope, their reply was “it’s too old”. It’s difficult to find good support these days. I probably would be unhappy with its resolution anyway. 🤷🏻‍♂️

I'm glad the videos are helping you get up to speed in the world of ASICs. I've tried bypassing a chip on the PCB before, but it doesn't workout too well. Could it be done, possibly. Should it be done [shrug]. Keep in mind, each domain (column) of chips is consuming 1.6V of the 21V on the card. So if you bypass a chip, or a few chips in a domain, you are going to change the resistance for that domain and throw things out of balance. The Stasic Board tester is supposed to have a new feature where it will do chip level testing without having to remove the chip. Couple that with a reliable chip tester if you are using recycled chips and you could definitely reduce the number of chips you replace. Assuming the problem is a bad chip and not something else.

@@iagmr Thank you for the insightful response! The boards definitely must have been running too hot cuz some heatsinks slipped off the chips and some even fell off the board completely. I managed to heatup some of the heatsinks that could slide back over the chips but the ones that fell off are pretty damaged. Bypassing chips now sounds like it's out of the question. Replacing them might be the only option. Are you still running your discord? Was going to post some pics there but the link was down.

Thanks! I don't know of any distributor selling the Thailand Team Miner tester. I'm not even sure they are still being made. Lucky me 🤷‍♂🤷‍♂. If I were buying a new tester today, I'd buy the PicoBT tester if I was really on a tight budget and didn't want to get a simple test jig from Zeus Mining or the like. However, knowing what I know now, I'd buy the Stasic tester if I could possibly swing the money.

Hey bro I am from India , I am aoso learning ASIC Repair, how can I contact you , what is your whatsapp number ?

The Bitaxe team has released version 1.0 of their ESP-miner, so now you don't necessarily need cgminer.

@@iagmr As far as I understand, raw software does not work on ESP, it has been checked :)

@@alexnoname9123 not sure what you mean... I'm running the v1.0 ESP-Miner release on my test unit right now and it works.... github.com/skot/ESP-Miner/releases/tag/v1.0

@@iagmr My test received work from the pool, but after the calculation it gave an error. Thanks for the link I'll take a look

@@alexnoname9123 I haven't been on discord in a while (too many distractions... like a new 3d printer). Skot and the team should be able to add some insight to the error if it persists after you get up to the 1.0 release. BTW: I had to lower the speed on my chips to <220 to run reliably in the socket. I'm waiting on a new board design to come back from the PCB maker, it will allow me to do a test with the chip in the socket, then solder it to the board and compare.

Great question. While both cameras have the same sony sensor, the Mokose camera doesn't have the same problems with video cutting out, turning green, etc. As well as support is better with the Mokose. Hope that helps.

I have electronics repiar shop so I dont use 4K recording. All whatvI care about is resolution, color, depth view, and the quality for the picture

​@@jannmedia I hear you. My Hayear did not work well at the claimed 4K setting. The image would stall, turn green, or just blank. It didn't matter if I had it connected to the computer via USB or HDMI connected to monitor @ 4k. These problems persisted and Hayear support failed to ever fix them or offer to replace the unit after I tried countless software and firmware updates they suggested. Mokose on the other hand has consistently worked well as a 4K camera whether I'm using it on the microscope, overhead or a macro upclose view. If you run your microscope cam through your computer, the Mokose will work well as it only has a USB output. If on the other hand, you need to go directly to an HDMI monitor, the Mokose camera reviewed in this video will not work as it does not have an HDMI connector. I did finally find a use for the Hayear. It runs OK at 1080p or even 720p. No over heating issues and no image issues. So it's connected to my 3d printer with Octoprint. Just curious, what microscope stand/boom are you using. I'd like to upgrade mine but I haven't found anything with less wobble.

@@iagmr Thank you for the great details, I think you answered my question since I use it with HDMI connected to Vizio TV over my table. For the stand I have Flexible Arm Digital Microscope Stand also have tabletop. But I was planing to get Articulating Arm Pillar Clamp Stand for Stereo Microscopes, then I come back to modify my Flexible Arm Digital Microscope Stand so I can change the head screw position by making new thread screw in the microscope lens ring so I can switch HAYEAR upside down since that is the only problem Im facing with this microscope, the pic will not match the item position on table. But I agree about some issues you have mentioned for the yellow color, which the problem solved after I upgraded the firmware

@@jannmedia I haven't ruled out that I might have gotten a bad Hayear, but since they really weren't interested in swapping it out after we went back and forth for a couple of weeks I don't care. It works at 1080p so it's not a complete loss. Glad the firmware fixed the color issues for you.

Hi there, I do not know of a seller for that tester. I do not recommend anyone purchase the Teamminer ASIC tester as there is no support. If you are from Thailand or speak the language, you can checkout their channel, www.youtube.com/@teamminer6093 Look at the Stasic Tester from @stasictech. They are under active development, offer good documentation and support is handled via Telegram channels in multiple languages. In the future I hope to review one for the channel.
