1  Bitcoin / Mining speculation / Re: Say. If somebody built another small miner... on: February 02, 2021, 09:14:22 AM
@sidehack I am interested. I am still holding on to my old S1/S3 units in case you ever finish your upgrade kit idea.
2  Bitcoin / Mining speculation / Re: FutureBit Apollo BTC - opinions on: February 02, 2021, 08:46:27 AM
I love the Apollo LTC. I picked up two "Batch 1" units during pre-order. I am planning to do the same with the newly announced BTC pre-order.

Is there an option for just the miner/node? i.e. everything except the power supply?

I used the futurebit.io contact form to propose such an option because I didn't see it on the pre-order page. I didn't even think to come here to suggest it directly to jstefanop. I am glad to see I am not the only one desiring such an option.

I'm still waiting for someone to explain why Full node software is a BIG feature. Can someone please answer:

Does it allow one to find more blocks?

Does it reward more blocks than a litecoin server such as tbdice.org?

Does it save electricity?

What makes having it on the Apollo such a BIG feature???


Having a full node directly on the miner provides miners with the capability to solo-mine without any additional hardware. Some folks consider this capability a big feature because it provides completely new functionality.

My question was legitimate. The first couple of lines of your reply is obvious and the stats of the Apollo are a given. To rephrase my question - are the hash speeds a fixed limitation of the hardware?

I prefer you don't answer philipma - please don't force others to read how wonderful your setup is nor your gloating. It was my understanding this was an Apollo thread - not a boasting with non-Apollo hardware one (or you have 1?).

BTW - you said "do not knock voltage and efficiency gains bro" - well gee bro, I never said I knocked them and in my first line said they are always welcome.

BTW2 - jstefanop's past entries have stated their market target - and it didn't include you, so back off and stop attacking beginning Apollo users just because you don't like how a question is phrased.

BTW3 - Yeah, I'm small scale as are many others here. Scales are relative so just remember your a minnow dweeb compared to the really big fish miners.
philipma1957 is 100% on target. He very tactful told you that you were asking the wrong question. Nobody faults you for not knowing why or how because you are still learning, but your question was like asking "will blending ethanol with gasoline make my car go faster?" Increasing a unit's hashrate post manufacturing through a software update rarely happens. When it does happen, the increase is typically anecdotal at best.

(1) Improvements to the voltage/efficiency of the ASIC chips could theoretically improve hashrate if the limiting factor is thermal. However, I believe that we are likely hitting frequency barriers inherent to the ASIC's architecture, but it is possible I am wrong.

(2) It is understood that functionality equates to features. This could lead to increased hashrate through increased frequency if that is the feature updated, but I would again state the likely frequency barriers of the architecture argument from (1).

philipma1957 is probably the most user friendly forum member willing to help newcomers. Having personally read a great many of his almost 30k posts over the last 6 or 7 years, I believe his statements regarding his gear and setup were meant to lend credence to his advice not gloat. You would do yourself a service to avoid expressing prejudice by listening a little more carefully and speaking a little less harshly. In case I am unclear, stop being rude.

... Btw any idea what the heck is causing this crash running cgminer with 1 newpac at 200mhz?  my pi is dead to the world. Can't login or anything I have to power cycle it.

[...]

I use multiple Raspberry Pi devices for mining and I see this type of error a lot. It almost always comes down to the SD card and/or the power supply. If it happens once a day around the same time, I would bet it is the SD card. The device is probably trying to run some cron job and the file systems takes a dive due to SD card issues causing a kernel panic.

I figured out what I was doing wrong with checksum, I was using MD5 instead of SHA256. The checksum on the IMG matches. I've tried to create an ISO on the micro SD using Etcher but it doesn't seem to be working. I've tried on a sandisk 8gb and a Kingston 16gb with no luck. There doesn't seem to be any settings in Etcher to change. I read that I have to make sure the image is on the whole disk not sure how to do that.
Etcher does not require any setting changes.

hi

i had same issue as wttbs miner went off line, the reboot option i dont think works, does not reboot device, had to do power cycle
was working ok for two day's and seems ok now to litecoinpool
I have not experienced any issues with using the reboot command. It appears to function correctly as intended. What were you trying to fix by rebooting?
7  Alternate cryptocurrencies / Mining (Altcoins) / Re: Official FutureBit Apollo LTC Image and Support thread on: December 23, 2018, 04:15:47 AM
I've been unable to get the apollo to boot. I ran a checksum on the image I downloaded and it doesn't match. I've re-downloaded twice and neither matches. Anyone have advice? I'm using a windows 10 pc and downloaded using both chrome and edge.

If itís flashing yellow itís working fine. What are you using to run the checksum?

Yellow flashing means itís booting and not getting a network connection. You have it plugged in via Ethernet and ran an ip finder on your network?

Thanks for the response.

I ran the checksum with command prompt, yes it's plugged in via Ethernet but it's not being assigned an IP by my network. Anything else I plug into the ethernet is immediately assigned an IP.
Did you hash check the IMG or the ZIP of the IMG?

Let me know if you want one. Or two. Or a bunch, that'd be cool too.

I am interested in getting at least two. Do you have a ballpark figure on the pricing? Will you be selling these direct or will you be using re-sellers only?

Ive been using the Microcenter cards for a few weeks now so don't think its that. Could be a bad controller then. Just let me know when you can send it over and ill figure out what it is.
Micro Center SD cards are notoriously bad for this type of application. I tried on several occasions to use them for different Raspberry Pi projects, but I always had weird unexplained errors.

For example, I recently built a mining controller using a Micro Center 32gb SD card with a Raspberry Pi 2 Model B for my Moonlander 2 devices and the Raspberry Pi would have random kernel panics about once every 12 hours. I eliminated those issues by swapping out for a SanDisk card.

Three 2Pacs and a terminus running on 4.11.1.  Looks OK here. TY vh & ch.
Is anyone else getting this?

 cgminer version 4.11.1 - Started: [1969-12-31 19:01:18.078]

My rpi date&time are set correctly and V4.10.0 reported it correctly. The messed up date doesn't seem to be affecting hash rate or share acceptance though, so may not be a big deal, just looks odd.
This is normal behavior for the RPi. It does not have a RTC and must therefore pull the current time from a NTP server. Applications that start before the NTP server is polled will show a time/date stamp consistent with your experience.

I am excited to see your next announcement.

I was psyched to see this announcement, but I had been hoping for the PayPal option you normally have on your website. However, I can understand why it is not an option with it being a pre-order and all.

Yesterday I added a 5V/2A (phone charger?) power supply to it which seems to work fine.
...
But when I plug in a second 2Pac this second one becomes active and the first one seems to drop in speed and the blue/white led stops flashing.
...
Your power supply is too weak. At the very best, you are going to get 10W out of that power supply, but likely much lower. One 2PAC can pull over 10W depending on your settings.

My home computer is on the fritz, so for the first time since I started mining in 2014 I don't have any miners plugging away at hash values.  Embarrassed
Hope to be back up and running soon.
I had 100% of my miners turned off for the better part of year. I know how it feels. For now, I am relegated to mining with USB miners for S&Gs. Such is life. Good luck getting everything up and running again!

Today marks 7 years since the launch of Bitminter. Thank you to all who mine and mined with Bitminter over the years.
Congratulations! That certainly is a milestone considering all of the pools that did not make it over these past years.
16  Bitcoin / Hardware / Re: Eyeboot USB Mini 2-Port USB 2.0 Hub Splitter with 5V 3 Amp power adapter on: July 01, 2018, 10:29:20 AM
thanks for the update, look forward to reading your review.

I must apologize klintay. I was unable to get around to reviewing the device until today. I posted it here: https://bitcointalk.org/index.php?topic=4577032.
17  Alternate cryptocurrencies / Mining (Altcoins) / Review: Eyeboot Mini 2-Port USB 2.0 Hub (works with USB miners like ML2 or 2PAC) on: July 01, 2018, 10:19:52 AM
I must first caveat the below review with the fact that I have had this device unopened and unused for a year. I received it in late June of 2017 from klintay at Eyeboot, but due to some unforeseen circumstances I was unable to provide a review until today.

Now, on with the review. I was generously provided with a new Eyeboot Mini 2-Port USB 2.0 Hub by klintay in order to test its USB miner capabilities.


I tested the DC 5V 3A hub with a FutureBit Moonlander 2 (ML2) using an Eversame USB Safety Tester.

BLUF (Bottom Line Up Front):
Pros:
  • Easy to setup
  • High interoperability (works with any USB port off of RPi, PC, etc.)
  • Provides 15W of power (I did not test beyond 7.5W due to Vdroop)

Cons:
  • Voltage starts a bit low (4.78V at idle)
  • Vdroop increases significantly as power draw increases (I observed a drop from 4.78V to 4.20V)
  • Only enough space on the USB hub for one USB miner (ML2 or 2PAC)

ML2 at idle: 4.78V 0.18A


ML2 at 600 MHz: 4.45V 1.22A


ML2 at 700 MHz: 4.36V 1.43A


ML2 at 832 MHz: 4.20V 1.82A


Conclusion:
The constructions of this device feels excellent. I certainly like the concept of this device, but I do worry about the significant Vdroop issue. I tested the USB hub with another 5V 3A power brick having the same barrel connector size and polarity and I observed a similar Vdroop across each tested frequency. This observation is interesting because the USB hub the second power brick belongs to droops to 4.60V. Overall, I like this device and I will continue to use it for lottery mining, but I would like to see the Vdroop issue resolved in order to better provide consistent power at loads higher than 5W.

I bought 2 x 2Pac usb miners. I got cgminer setup, but for some reason when I run cgminer only 1 of the 2pac's will run. Using cgminer -n I can see both devices, but when looking at USB management menu within cgminer it only show's 1. How can I enable both 2pac's to mine at once?

Edit:

I just tried changing the USB device used with the --usb 2:11 argument in my batch file. It says device not found. Why is it detecting both devices with the -n command but when running cgminer.exe it only detects one device, not both?

Thanks!
How are you powering both devices?
