Close up Senko Hanabi xoltri 2024-03-11 | It's neat to see the tiny dross ball burn all the way up the sparkler. Managed to take a (somewhat in focus) close up as this happened. Enjoy!
120mg Senko Hanabi xoltri 2024-03-03 | After making thousands of these I have finally settled on a wrapping technique that works consistently. Check out this sparkler with 120mg of composition.
Senko Hanabi - crackling old age. xoltri 2024-02-22 | Really excellent result on this one, the Senko lasts until old age and continues to crackle as it burns the whole sparkler.For more info:Experimenting with different compositions, this is a 70%/30% mix of my ratio and NightHawkInLight's ratio from this video: youtube.com/watch?v=5oULEuOoRd0. I combined them via math on my spreadsheet and then ball milled the components for 24h.This ratio works out to 46.73k 37.88s 12.17c 3.22Lb, but you can get more details on my spreadsheet: docs.google.com/spreadsheets/d/1Tubx4Db3d_rg_4VsoQvPAYn4J4Z6GzzujE9TOLrYVvk/edit?usp=sharingReally liking this composition, I hope to post a more comprehensive video soon.

Senko Hanabi - Delayed crackling xoltri 2024-02-13 | Still honing my wrapping technique, made some good Senkos tonight after some that didn't work too well, all with the same composition. Here's one I filmed with 100mg of composition, enjoy!
Back at the Senko Hanabi xoltri 2024-02-05 | I've been making Senko Hanabi again, over the last couple of weeks I have made several hundred.I think I have made some progress on the wrapping technique. Here is one using 100mg of my composition, in my opinion this is an ideal result showing all stages.
Eclipson Model T wing failure xoltri 2023-08-18 | Had a catastrophic wing failure with eSUN LW-PLA, still investigating why.
Senko Hanabi - Fluttering at 140mg xoltri 2023-02-22 | Here's a better view of the fluttering effect at higher weight senkos. These two have 140mg each and the fluttering effect is more pronounced. Would be curious if @Nighthawkinlight or @GuillotinedChemistry have seen this before on a non-carbo senko. It's particularly good on the second one in this video.
5 Senko Hanabi in 5 minutes xoltri 2023-02-22 | I have made close to 1000 senko hanabi in the last two months and I have made some significant progress in crafting them. Here's 5 senkos that have 120mg each. At this size, when wrapped tightly sometimes there is a new effect. Just after birth the dross ball will send out large globules that flutter down via gravity, which is different than the usual sparks.
Winter Senko Hanabi firework ends with a *pop* xoltri 2023-01-20 | My latest batch of Senko Hanabi, filmed mostly from above. After the old age stage is over the dross ball often falls off, and if it's over the snow it explodes in sparks with a loud pop sound. Really neat!
Senko Hanabi 5 vs 5 xoltri 2022-08-31 | First five Senkos are from a composition I made a while back but have since run out of. Tonight I wanted to try making another 20g of composition, and the last 5 Senkos are the result.Pretty happy with the result as the last composition I made took several days, but this one was just a couple of hours.Dropped my phone at the end!
Senko Hanabi summer night. xoltri 2022-06-11 | Perfectly calm night, so I pulled out my ethanol fireplace and a senko that I made a while back.
A private garage fireworks show. Another Senko Hanabi video! xoltri 2022-01-19 | I have made many hundreds of these up to this point and I am getting much, much better. Here are 3 Senko Hanabi fireworks, one after the other.Having the ability to have a fireworks show anytime you want it without disturbing the neighbors is something special.Potato cam quality courtesy the super cold weather and frozen hands. I will do better in the future.
Senko Hanabi sparkler xoltri 2022-01-05 | This is the result of about a weeks worth of targeted effort to perfect the method @Nighthawkinlight developed in his video on non-flamable fireworks here: youtube.com/watch?v=O3-ucafI1MYI've probably made a couple hundred of these to get to this point. There are many variables that must be controlled to get a good result, but once you know what they are they are fairly easy to make, and extremely rewarding.Once I coalesce on the things I've learned I'll post a follow up with more detail. But I couldn't resist uploading this result - these are super awesome fireworks. This one even exploded in a shower of (harmless) sparks in the end.

ADS 400q vertical performance and more problems xoltri 2014-05-31 | Was just testing the vertical performance of the 400 Q, and then discovered I have another issue. luckily I got it on the ground in one piece and didn't crash.

Pixhawk sync issues part 4 xoltri 2014-05-06 | Did more troubleshooting and found an interesting discovery regarding the BEC power and power module.
Pixhawk, another crash. xoltri 2014-04-13 | Trying out the RC_SPEED paramter set to 100 instead of the default 490 in flight. It seemed to solve my sync issues on the ground, however you can see the bad wobble that I am not doing as I try and loose altitude before I crash.This is my first ever FPV flight so I think if I had more experience I wouldn't have crashed, so that's my fault. Only broke 3 props, no other damage. On an ADS 400Q.

Wine degasing with a medical vacuum pump. xoltri 2010-08-19 | I learned how to do this from Kiteboarder on winepress.us forums. This is a Schuco-Vac vacuum pump. It degassed the wine in about 15 minutes, using about 22" hg. The key is you need to pinch the supply line to create turbulence and ensure your pump can keep up with around 20" mercury vacuum.
