Bozzle Tungsten Carbide Nozzle – 0.5mm

The Bozzle nozzle is the very first high flow (and lower back pressure) tungsten carbide nozzle for 3D printing applications.

Tungsten carbide nozzles are capable of printing all 3D printing filaments due to their exceptional hardness, ultra high operating temperature and high thermal conductivity.

0.5mm orifice
No inserts – constructed out of a solid piece of tungsten carbide there are no inserts here
Non stick surface finish
Significantly increased layer to layer adhesion at same printing temperatures vs hardened steel nozzles
Compatible with V6 and MK8 hotend heatblock

This nozzle requires hot tightening. Install the nozzle, heat hotend to 20c over desired use, and hand tighten with a 6mm or 1/4″ socket.

This nozzle will print every material.

Analog Man Prince of Tone overdrive

Description

The POT is pretty much the same as half of the King of Tone, with an external MODE switch standard. It is the same as the KOT with HIGHER GAIN option, so you can use the full range of the DRIVE knob and it has a little more drive at the top than a normal gain KOT. The DISTORTION mode is improved though, for a louder, stronger distortion sound. See http://www.kingoftone.com for more info.

Power Jack is standard on the POT –

The TREBLE trimpot is inside, just like the KOT.

There are also two new DIP switches inside! They are a bit subtle at some knob settings and modes:

DIP1 : LO-MID lift switch. The tone from your lower strings will be enhanced a little when DIP switch is ON.

DIP2: TURBO switch- with higher gain settings you’ll hear deeper compression, especially in DIST mode. You will hear a brighter, crunchier sound with this on at higher DRIVE settings when this DIP switch is ON.

The three modes, as on the KOT, are:

1) Normal Overdrive mode (OD mode): This is the standard King Of Tone sound, – a touch drive available than a tube screamer. Can get much louder than a tube screamer. The RED side of KOT has this setting from the factory.

2) CLEAN mode : This mode has less distortion, it can be used for clean boosts or clearer, louder sounds. It’s sort of a cross between a true clean boost and an overdrive. CLEAN MODE is even less compressed and louder than the OD mode. I love this mode with high drive settings too! The YELLOW side of KOT has this setting from the factory.

3) DISTORTION mode : more drive than the standard mode- a touch of hard distortion. The sound is more compressed, yet retains the pedal’s character. Same volume as OD mode.

At low DRIVE settings, or when playing softly, there is not much difference between the three modes, they all can get pretty clean and have the same level at low drive settings. The ability to clean up when playing softly is a very useful feature of this pedal. The Drive knob works like the KOT with HIGHER GAIN OPTION, so you can set it anywhere and get great tones.

The DRIVE knob taper is different than the KOT. It comes up faster and more linear, while KOT has a lot going on from 2:00 to max. So comparison to a KOT with HG option will not be the same at the same knob position unless it’s up all the way, where they are the same.

We are making these by hand in China by the same people who are making our Analog Delay. Though it’s made in China, we use the same parts as the King of Tone – best Japanese chip and capacitors, not cheap Chinese parts. No surface mount parts, NO ROBOTS, everything is vintage style and hand wired for easy maintenance and repairs unlike most Chinese pedals and most USA “boutique” machine-made pedals which are disposable if they have any problems like a pot, jack, or switch that wears out.

POWER SUPPLY: A Standard Boss PSA120 type 9V DC adapter will work fine. Center is negative. The pedal uses only about 6mA of current at 9V. You can get a fuzzier sound if you want, at lower voltages, for example the SAG mode on the pedalpower2. When your battery dies you will notice the pedal will not get nice and clean, the sound will be hairier. Use a good Alkaline battery or a power supply for best results. You can use higher voltage for more headroom, 12V is common, 18V is safe too. Clean boost may be improved the most with higher voltage.

CHIPS: You can also try other standard dual op-amp chips in the Prince of Tone. Just make sure you put it in the right way, with the pin#1 dot on the side with the chip socket cut-out. The TS-808’s JRC4558D chip sounds good in this pedal, especially with single coil guitars and smaller Fender type amps. You can try a high fidelity chip for the CLEAN mode which may work well.

Size
We made our own case for this pedal, it’s lower and a little shorter than our Beano Boost / Orange Squeezer / large SunFace box, and a little bigger than the Astrotone / Peppermint / small Sunface size.
Size is 2.5″ wide x 4.5″ long x 1.5″ tall, not including switch/knobs/jacks.

Buffer option
If you run through some long cables to your amp, or through some tone sucking pedals (volume pedals, etc) you might want to add the optional buffer inside the POT. If you run the POT into a pedal with a good buffer like our ARDX20, then it’s not needed at all. There is no room for a battery with the Buffer option. The buffer will work great at higher voltages like 12V or 18V also. See our BUFFER page for more info.

Prusa Mini Bear +

I made an overview of all mods done to my Prusa Mini + 🙂
With lots of thanks to so many different people on Thingiverse and Printables

Prusa Mini+, mellow V6 alu cold block/heatsink, mellow brass heater block, mellow silicon heater block sock, E3D v6 Titanium heatbreak 1,75 mm (origineel), Bondtech CHT 0.4mm nozzle, LDO Orbiter 1.5 extruder, Weishuo 24V-10A-240W PSU, Raspberry Pi 3a, Argon1 FanHat, Raspberry Pi PSU 5.1V 2.5A MicroUSB, Prusa Stepper motor Z-axis, Misumi Linear bearings kit + superlube, AluX Bear mini 2040 extrusions, GT2x6 mm Kevlar-reinforced timing belt (2,5 meter), USB-USB-c kabel, wiring + plugs, printed parts, High Power MOSFET 30A, fans, PrintBay Heat bed insulation, buck converter

Replace basic Volume2, with bigger HDD

1- Remove disk on tray 1 (named Volume1 in this tutorial), reboot
2- Insert the new bigger disk in tray 1
2a- ‘secure erase’ new HDD, reboot
3- Convert volume2 to RAID1. (I’ve not selected SHR, but RAID1), reboot
4- Exchange disks in Tray2 and Tray1, reboot
5- Remove disk in Tray 1, reboot -> Degraded status
6- Issue

Putty:
mdadm –grow –raid-devices=1 –force /dev/md2

7- Go to DSM Storage manager, HDD manage, you will have the option to extend volume 2 to get the full available space. Do this. Reboot
8- You must here have a Volume2 using the new hard disk, and with the full available space
9- Insert the previous disk Volume1
10- Here all should be fine, you should have Volume2 unchanged, but on your new HDD, with a whole available space

Three additional comments:
1. He replaced both disks (Basic Volumes 1 and 2) in his diskstation by running two times through the instructions by MathieuM68. Therefor he swapped the instructions on disks, volumes and trays accordingly. It works without problems and afterwards the system runs solid and with the same configuration like before, but with larger disk space of course 😉

2. In order to issue the command “mdadm” on the right RAID device (/dev/md?) I used

Putty:
cat /proc/mdstat

which lists all available RAID devices.

3. He could not issue the command “mdadm” directly, but it works with

Putty
sudo mdadm –grow –raid-devices=1 –force /dev/mdX

Do you even orbit?

These 2 overviews above are wrong cause ‘they’ used orbit data -around the sun- to calculate how long a planet was in a gate or line, but the movement around the Rave Mandala wheel is an orbit -around Earth-.

So I did some calculations and came up with this:

Mercury as short as 358 days and as long as 405 days, on average 366 days.
Duration in one Gate: ~5.7 days
Duration in a Line: ~22.9 hours

Venus as short as 293 days and as long as 410 days, on average 369 days
Duration in one Gate: ~5.8 days
Duration in one Line: ~23.1 hours

Mars as short as 528 days and as long as 712 days, on average 679 days.
Duration in one Gate: ~11 days
Duration in one Line: ~42.4 hours

maybe 64Keys were right in their overview:

Original Prusa Mini+ Bear mod

today, I finished the main modification of the printer (I only want to change the wires soon) so the whole frame is changed, the hot-end, extruder, heatbreak and nozzle, and all printed parts were PETG are now ASA, instead of a Cantilever design it is now an H-frame with double Z axles, so the frame gives rigidity and structure to the printing, yet still running the original Prusa firmware (with some added G-codes)

Rocket Transits Rippling Sun

Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

2022 May 31

The featured image shows a Falon 9 rocket transiting in front of the Sun in mid May. The heat from the rocket's exhaust makes the Sun's outline appear to ripple. Please see the explanation for more detailed information.

Rocket Transits Rippling Sun
Image Credit & Copyright: Michael Cain
Explanation: The launch of a rocket at sunrise can result in unusual but intriguing images that feature both the rocket and the Sun. Such was the case last month when a SpaceX Falcon 9 rocket blasted off from NASA’s Kennedy Space Center carrying 53 more Starlink satellites into low Earth orbit. In the featured launch picture, the rocket’s exhaust plume glows beyond its projection onto the distant Sun, the rocket itself appears oddly jagged, and the Sun’s lower edge shows peculiar drip-like ripples. The physical cause of all of these effects is pockets of relatively hot or rarefied air deflecting sunlight less strongly than pockets relatively cool or compressed air: refraction. Unaware of the Earthly show, active sunspot region 3014 — on the upper left — slowly crosses the Sun.
