Why Are My Gridseed Blades Exploding? What Components Are Exploding?


Does any one know how i can assign separate workers for each of my gridseed units?

I cant seem to find any documentation regarding this, and i am hoping someone has already done this?

My config looks like this:

{ "gridseed-options": "baud=115200,freq=850,chips=40", "gridseed-freq" : "8D6E50A55748=900,8D9136685748=875", "kernel-path": "/usr/local/bin", "failover-only": true, "verbose": true, "api-listen": true, "api-port": "4028", "expiry": "120", "hotplug": "5", "log": "5", "no-pool-disable": true, "queue": "1", "scan-time": "30", "scrypt": true, "shares": "0", "pools": [ { "url" : "stratum+tcp://uswest.wafflepool.com:3333", "user" : "worker", "pass" : "x" } ] }...

Have you had success using that as I couldn't get it to work. I tried it on one of my miners and it kept coming up error connecting. I then tried it on my laptop which didn't even try to connect to the blades but then as soon as I used bfgminer it worked - but not at the desired hashrate.

I was able to hash one blade at 5.4 MH/s

First you config your Bat file i.e. pool, username, password, and miner clock speed.

--gridseed-options=baud=115200,freq=800,chips=40 --hotplug 5

As you can see I set mine as 800 Mhz and the 40 is the number chips per board. since each board as 40 chip that that 40 is needed and each blade is 80 chips (2x 40 chip)

As I say start miner first then plug miners in one by one. Did you have a screen shot of the...

Well, just wanted to do a short update on optimizing the Gridseed Blades a bit more.

I found that you can actually run these Gridseed Blades at 850Mhz just fine, there’s some more hardware errors but hashing is a bit faster and getting around 2.879Mh/s per blade.

Here’s my cgminer.conf file:

"pools": [
"url": "stratum+tcp://us.clevermining.com:3333",
"user": "1NqW6oZ5bvLPjWfr6DrzUhLF8X9iLA7TVW",
"pass": "123123"
"url": "stratum+tcp://",
"user": "DFMVvKYruZKkuAapuHx1wHvZPxPYFayAZa",
"pass": "123123"

It didn't really "exploded", your cooler fan just got problems on it's coupling(ok, then you could think that it exploded, but it just uncoupled). Your video card probably is still running because it is still dissipating heat over the cooler fins, however, it will not work when it hit high temperatures due the fact that your fan is not cooling the fins anymore. I would keep it turned off until you change your VGA cooler because you can permanently damage it with overheating.

To get your onboard graphics, check on your BIOS settings if it is enabled, probably when the manufacturer installed your offboard VGA, they disabled it on BIOS.

You could easily change it for a new one just such this one and(probably if no permanent damage on chip was made by heating) everything will run ok...

I'm wanting to get into mining not so much for the mining reward but because I support the idea of decentralised currency and the power of peer to peer transactions.

However I have a problem with getting some Gridseed Blades up and running. Something on them is exploding. Please see the below photos.

This is my power supply unit.

I live in the UK so the voltage is set to 220V mode.

This is the front of the PSU wired up. My multimeter reads 12v coming from the output.

I'm in the middle of building a stack of blades but I need to overcome the problem of something in them exploding.

In this photo you can see there are three components that have exploded. What are these components? What would cause them to explode?

This photo is for comparison, this is a good blade where the components haven't exploded.

I've tried to look for a datasheet or a gridseed blade board schematic but I can't find one.

Every time I connect a...

For this month’s Rig of the Month, check out the latest ASIC Scrypt miner, Gridseed Blade Mining Rig!

Based on 80 Gridseed chips, Gridseed Blades are ASIC Scrypt miners capable of 5.6Mh/s at only 100 watts of power. These currently (as of April 30th 2014) cost around $1500-1600 with ROI of around 6 months at $15/day. (You can use CoinWarz.com to see profit at the moment.)

In other words, these are the best rigs to use to mine Scrypt coins such as Litecoins and Dogecoins “right now”. My graphic card rigs are actually losing money at this point, I am barely breaking even or losing money. Unless you have free or really cheap electricity, graphic card rigs are really starting to lose its merits (but this may change if coins like Vertcoins start going up.

Gridseed Blades use the same chips as regular...

An exploding target is a type of explosive that after being shot by a 223 or other larger rounds explodes upon the impact of the bullet. It is usually a mixture of aluminum powder and ammonium nitrate. Exploding targets are legal to produce but are restricted and may sometime be required to seek permission from the relevant authorities. Responsibility and safety is paramount when it comes to exploding targets. Before coming up with any recipe one should always focus on safety.

An explosive is only created when two or more parts are mixed. In an exploding target recipe, one part should be the oxidizer while the other should be the catalyst. The oxidizer supplies extra oxygen to the catalyst thus making the explosion possible and very powerful. You can use ammonium nitrate as the oxidizer and dark aluminum powder (dark aluminum flake) as the catalyst. There are other options of mixing with other components in order to change the blast characteristic. However, the earlier...

Mobile phones may be treated like playthings these days. However, these flashy gadgets can prove dangerous if not handled with care. Several instances have been reported about the phones blasting off suddenly, the latest victim of which was a 14-year-old child of daily wage workers from Seoni. The blast was so bad that the boy narrowly escaped death and ended up with severe disfigurement to his jaw, nose, mouth and face. TOI tells you the do's and don'ts of handling mobile phones.

What are the things to be kept in mind while buying mobile phones?

Buy a branded phone as far as possible. Ensure that the phone has a proper IMEI number, which is a code that identifies each phone. Check that the number on the phone corresponds to that on the box and receipts.

It is considered wise to check the accessories such as earphones, battery and charger. Make sure the battery description such as voltage value matches with that of the charger to avoid overcharging which...

It is far far better that a fuse sometimes blows when there was no need for it to, than for it to sometimes fail to blow when a fault condition exists.

Blowing a fuse. The term "blow" will be used here for the fusing of a fuse - the act of melting the fuse wire and breaking the electrical circuit. Terms such as "it blew a fuse" and "why did the fuse blow?" are common here. The term "blow" in this context may be less common in some countries. Using "fuse" which is correct, as in "the fuse fused", is liable to be too confusing :-).

Why do they blow?
Should they?
The purpose of a fuse is to protect equipment and wiring against the damaging effects of electrical faults which cause excess currents, and to disable equipment which is faulty. The fuse "blows" when the current carried exceeds the rated value for an excessive time. The higher the overload the shorter the period before the fuse blows. So, equipment which is meant to "draw" 10 amps but...

Exploding head syndrome (EHS) is a benign condition in which a person hears loud imagined noises (such as a bomb exploding, a gunshot, or a cymbal crash) or experiences an explosive feeling when falling asleep or waking up.[1][2][3] These noises have a sudden onset, are typically brief in duration, and are often jarring for the sufferer.[4]

Exploding head syndrome is classified as a parasomnia and a sleep-related dissociative disorder by the 2005 International Classification of Sleep Disorders[5] and is an unusual type of auditory hallucination in that it occurs in people who are not fully awake.[6] Neither the cause nor the mechanism of exploding head syndrome is known.[6] As of 2015 there had not been sufficient studies conducted to make conclusive statements about prevalence nor who tends to suffer EHS.[7] It was once thought that EHS was rare (occurring primarily in females, those over 50 years old, and those suffering from sleep paralysis) but a 2015 study indicated...

This article is about the abrasive cutting tool. For the 2017 Overkill album, see

The Grinding Wheel


A grinding wheel is a wheel composed of an abrasive compound and used for various grinding (abrasive cutting) and abrasive machining operations. Such wheels are used in grinding machines.

The wheels are generally made from a composite material consisting of coarse-particle aggregate pressed and bonded together by a cementing matrix (called the bond in grinding wheel terminology) to form a solid, circular shape. Various profiles and cross sections are available depending on the intended usage for the wheel. They may also be made from a solid steel or aluminium disc with particles bonded to the surface. Today most grinding wheels are artificial composites made with artificial aggregates, but the history of grinding wheels began with natural composite stones, such as those used for millstones.

The manufacture of these wheels is a precise and tightly...
