I have check with the latest IZpack installer version available (March 9th) and put the jar in the plugin folder of the Spark install folder (c:\progamme\spark\plugins). It is not working. I have also tested with a fresh user profile. May need some reworking.

I have compiled 10988 and it doesnt flash now, but i cant find flashing settings in the preferences. I think flashing should be turned on by the default, as most of the users would expect some new message indication i think.

I have tried to reset the photon. I have reflashed the photon using the dfu-util by flashing tinker, then running particle setup. When I flash my code again through the WebIDE, it will work for a short amount of time and then stop logging again.

Note that the Particle.publish() rate is once per second with a BURST of up to 4 per second. So doing once per second is just fine and I believe the DHT22 max sampling rate is 1 per second as well (though it may be once per 2 secs).

A couple of notes. I have tried reflashing tinker to the device via dfu-util and through the iOS app. In both cases, it seems to work fine, I can read and write to pins etc, but I continue to get the flash failed error in the dashboard. When working with my own code, I get the failed error and it will sometimes publish data for a short while, but eventually stops reporting with no error.

I wonder about the possibility of this issue (of seeing FAILED in the console after flashing) having anything to do with the firmware since I observed that flashing THE SAME firmware in a photon gives me the FAILED message, but if I use one of my cores it does NOT fail.

In both cases the firmware running is the correct one, so there seems to be something wrong when flashing a photon, hopefully just the reporting of the result.

I tried doing the same experiment from the BUILD web interface and from DEV (Atom running in Ubuntu) and both give the same results.

It definetly is an issue with the reporting mechanism and most the time not your fault and you can't do anything about it.

It's the way how the device would report fail/success and how the cloud gets to know the outcome.

That's normal. It's a very short duration, partial power flash that the camera fires before the full power flash, to measure the distance to subject and amount of light needed by the flash when it fires. A "pre-flash", if you will.

If you press the depth of field preview button then the flash will flicker brightly for about a second. It is essentially pulsing the light very rapidly and it makes a buzzing sound. This can also happen when using the flash as a focus-assist light. This is normal and not a defect.

You can buy an external shoe-mounted flash such as the Canon Speedlite 430EX II. This speedlight fires a red pattern/beam (focus assist beam) which allows the camera to lock focus on your subject without needing a white light to focus.

But why does it "buzz" (it's like an electrical short buzzing sound and is most annoying)? So, although I understand that the flash goes off rapidly to assist with focus, I don't understand "why" it needs to make that audible noise - which is both distracting to the photographer and the subject(s), often invoking a look - or comment - such as, "What's wrong with your camera?"

The buzzing happens because firing the flash at the required intensity calls for the application of a very high voltage. Inevitably, some of the necessary energy is released into the atmosphere and perceived as sound. Believe me when I tell you that Canon (or Nikon or Sony or any of the others) would prefer to use that energy to make the flash brighter or conserve it for later use. But unfortunately, the laws of physics are what they are, and none of those august institutions currently possess a way to override them.

The reloaders also have unhelpful descriptions. When I was a newer player, there was nothing to tell me if a reloader would work for certain weapons other than cannons and rockets. Before I had a damage meter, I had to go into bedlam and find the meter and test it out (hoping I survived long enough to do so).

You sure the flash got much more damage than the spark, i tested it out some builds in the exhibition and i think flash prob did like 760 on the damage meter or something like that and spark was like 720.

The flash sintering may involve the following mechanisms. Joule heating24,33 generates fast sample heating rates which may result in a thermal runaway34 leading to accelerated sintering35 as in experiments reported in ref.36. The grain boundary melting or softening have been reported for microwave flash sintering37 or for a traditional flash sintering process38,39. The nucleation of defects40,41,42, local overheating of the grain boundaries19 or the acceleration of sintering resulting from the dielectric breakdown when high electric fields are employed43 are also possible mechanisms of flash sintering.

In this work, the applicability of the net shape flash spark plasma sintering (NSFSPS) technique to a wide range of materials from metals to electric insulators is presented. Contrary to the previously used sinter-forging flash SPS method49,51, the NSFSPS approach uses a graphite die electrically insulated by a sprayed boron nitride layer55 to concentrate the electric current into the sample, if electrically conductive, or in the nearby graphite foil, if electrically insulative. The graphite die allows an easy control of the final shape of the specimen and makes the overall pressure assisted process more stable. The NSFSPS approach uses graphite tools for high temperature applications and good thermal shock resistance. This method is related to the electric current concentration approaches introduced by Zapata-Solvas et al.56 for ceramic powders (ZrB2, MoSi2, Al2O3) in flash conditions and by Romn-Manso et al.57 for the densification of SiC. However, in contrast with the above-mentioned techniques, the different current patterns employed in this paper demonstrate that an unordinary thermal runaway can be instigated by the electric current assistance for all kinds of the tested materials. The present study includes a numerical simulation to determine the efficiency of the flash heating phenomena for the different materials tested. This study demonstrates the possibility of a flash, homogeneous, energy efficient and near net shape sample sintering applicable to every material regardless of its electric conductivity.

The new NSFSPS method represents an efficient way for the mass production of small objects with optimal production time and high material performance. The fabrication of large size objects is possible too but will require a specific design of the electric current path in the NSFSPS tooling to balance the amplified thermal gradients. Thus, contrary to the regular flash sintering approaches, the presence of the graphite die opens the prospect of the one-step production of complex shapes similarly to conventional powder metallurgy approaches.

Net shape flash spark plasma sintering configuration, the lateral graphite foil is coated with a boron nitride spray to electrically insulate the die and concentrate the electric current on the sample.

E.O. managed the overall project. C.M. and G.L. conducted the S.P.S. experiments. G.L conducted all the S.E.M. characterizations. C.M. performed the finite element simulations. C.M. wrote the paper with input from G.L. and E.O. E.O. refined the paper. All authors contributed to the interpretation of the results.

So I pulled out all the plugs, and cleaned the porcelain sections and the plug boots with IPA and 320 grit sand paper to remove the carbon trails, then I slathered some 3M Silicone Paste ( dielectric grease ) on the porcelain part of the plugs and dabbed a little into the boots.

So far so good, the hesitation is gone and the increase in power is noticeable. It seems to have helped somewhat with the idle as well, although that's really a separate and intermittent problem, which I suspect is due to either clogged / leaky injectors or a wonky fuel pressure regulator.

I think your problem is your plug wires. I think they are leaking along the boot and down to ground (earth). With this loss of energy, you'll also see the large carbon buildup on the business end, due to unburnt fuel deposits. Since you are saying you are seeing the carbon tracking on the number one plug again, this is my reasoning for telling you the plug wires. Since they haven't been changed, this is the most likely culprit.

Also, whenever you put new plugs or wires on, use dielectric grease. Squirt a little into the boot just before you put it onto the spark plug. This will do two things for you. First, it will keep electrical leaks like this to a minimum. Dielectric grease doesn't transmit electricity, so it becomes an insulator. Secondly, it will also keep the boot from adhering to the porcelain of the spark plug. If you ever need to take the boot off the plug for any reason, it will come off a lot easier.
