Cryptocurrency scammers raked in $4.3 billion worth of digital money in 2019, more than triple 2018’s haul. That’s according to the latest in a series of recent data drops by blockchain analytics firm Chainalysis, all of which it has included in a lengthy report it published Wednesday entitled “The 2020 State of Crypto Crime.” You’ve…

This is the Juuke box. The Juuke box is your own musical friend, made to be as easy as possible to use. It is especially designed to be used by elderly and kids, but can of course be used by all other ages. The reason we created this, is because of my girlfriend's grandmother.
She told me that her and her grandma sitting in the kitchen, listening to music, dancing and laughing. Sadly, through the last years, her grandma has been in and out from hospital. On her worst days, however, music is one of the few things that still makes her smile. And music players like CD players are just too hard to use for her. That’s why we created the Juuke.

The Juuke Box works by using RFID cards to play specific songs from an SD card. You could also play the songs randomly using the green button, or play and pause with the red button.

saw this cool project a little while ago right here on Instructables. The author Ananords created an RFID music player that could be used by children or people who might not have the capacity to be able to operate a normal mp3 player/device. The original project is called Juuke can be found here. He created this project for his girlfriend's grandma and it is the perfect project to make for someone with Alzheimers or Dementia. This bit really hit home for me, as I lost one of my grandparents to this awful illness and I know that she would have loved something like this.

The basis of the project is that the player has two buttons, one to play/pause the music and one to shuffle all of the songs. You can also select an RFID card and place it on the reader to play that particular song. It therefore takes some of the nostalgic parts of listening to music (like choosing a physical CD or cassette to play) and combines them with new technology making it accessible for those with certain needs.

Even though my Oma (Grandma) is no longer with us, I still wanted to make the project and when my parents were cleaning out some old things from their house, I came across my mum's old cassette player, and thought 'this is it'! I've used the cassette player as the basis for my very own Juuke. I put together everything as per Ananords' instructions and it all worked well, but I had a couple of other ideas that I wanted to incorporate including:

The ability to play an entire album from one RFID card,
The ability to skip to the next song,
The ability to play a 'side B' of the card, just like the side B of a cassette tape, and
Utilising the same amount of buttons, but incorporating long/short press functionality.

Consul is a service mesh solution providing a full featured control plane with service discovery, configuration, and segmentation functionality. Each of these features can be used individually as needed, or they can be used together to build a full service mesh. Consul requires a data plane and supports both a proxy and native integration model. Consul ships with a simple built-in proxy so that everything works out of the box, but also supports 3rd party proxy integrations such as Envoy.

The Crimson project is an effort to build a replacement ceph-osd daemon well suited to the new reality of low latency, high throughput persistent memory and NVMe technologies. Built on the seastar C++ framework, crimson-osd aims to be able to fully exploit these devices by minimizing latency, cpu overhead, and cross-core communication. This talk will discuss the design, current status, and future direction of the crimson project.

Weinzierl berät österreichische Gesundheitsdienstleister bei der Einführung von effektivem IT-Zugangsschutz und hat die Implementierung von Worldline ID Center und biometrischer Authentifizierung in einer Reihe von österreichischen Krankenhäusern begleitet.

"Wer so schwer beschäftigt ist mit dem Corona-Management, startet nicht noch etwas Neues", erklärt er sich die Zurückhaltung der Politik. Für Foitik bleibt die Digitalisierung der Kontaktnachverfolgung "im 21. Jahrhundert" dennoch das Gebot der Stunde. "Server-und Leitungskapazitäten sind leicht skalierbar, die Personaldecke in den Bezirksbehörden nicht."

These are clamps for the prusa i3 mk2/3 for transport. They will fix the belts and the Z-Axis. This is a remix of the original prusa transportation clips.

Note "Z-axis nut" is also needed for X-Axis fix

Additional hardware:

3x M3x20 cylinder head screws
3x M3 square nuts

Call it the End-Fedz Trail Friendly killer if you like. This thing is much smaller and lighter, and a perfect match for the Mountain Topper series radios when you build in some traps or links.

Needed Materials:

• Special BNC connectors: https://amzn.to/38riPF7
• Toroids for this project are FT50-43: https://amzn.to/2NU7vbc

• 28 ga magnet wire: https://amzn.to/2AyjpEI
• Poly-Stealth 26 ga antenna wire. I've ordered from this company a few times and had great service: https://www.amateurradiosupplies.com/...
• 5 minute epoxy: https://amzn.to/2ZAAFRZ
• 5/8" or 3/4" heat shrink tubing (adhesive lined preferred): https://amzn.to/2VK5Rgq

I’ve found the perfect enclosure for my Prusa i3 MK3 3D printer (no modification needed!). It’s a cheap server wall mount cabinet for only 79,- EUR. You can find it on ebay or in different computer online shops. It has 4 mm safety glass and powder coated sheet metal walls. The roof and bottom have cable entries and the roof is also prepared for mounting 2 x single fans. That may come in handy if you want to build a fume exhaust for ABS printing.

This cabinet is available in different sizes and colors. But you need the biggest one (with 15 Height Units and 600mm depth) and the Prusa i3 will fit perfectly. Also the heat bed cable on the backside of the i3 has enough space without touching the enclosure, no modification needed. Since this thing was meant to be mounted on a wall it’s baseplate is not that sturdy. Don’t use rubber feet directly on the bottom side of the enclosure it will be too wobbly! Instead screw a thick plywood board to the bottom side to give the enclosure more stability. On that plywoodboard you can now fix some rubber feet to it if you want to use it on your desk.

As a fan of Adam Savage's Tested I of course had to build his custom workbench LED lamp! So I designed a mount for the lamp to the Loc-Line system and a base to mount it to the table!

Update 8/12/18: Added vertical_extension_plate. This lets you join extension tables to the main table along the direction of the blade. You will need to use screws to use this; it uses the holes in the legs of the tables. Note that this does limit the use of the fence.

Update 12/13/17: Added a storage spot for the Router Support Plate under the left and right Flex Holder Table. Uses two 10mm M3 screws.

This is a transformable and adjustable rotary tool based table saw / disc sander / shaper for use with the Dremel Flex Shaft attachment. The Flex Shaft should fit most rotary tools, but be sure to check.

Lets you:

Mount cutting discs to perform straight or angled cuts thin wood, pcb's, screws, plastic parts, etc of any length.
Mount sanding dics for disc sanding.
Mount sanding drum or grinding bits in the shaper configuration for spindle sanding/ grinding.
Mount other bits for other operations that I haven't thought of.

I was inspired to make one of Adam Savage's awesome custom LED workbench lights (link below), but wanted a more flexible mounting option. I'm a big fan of the one-handed quick clamps and thought this type of solution would be ideal. I decided to use a Harbor Freight 12 in ratcheting clamp ($3.99) as the core and designed mount for the lamp that would replace the far end of the clamp. My goal was to incorporate all of the clamp parts making it a direct swap.

I also wanted to be able to plug and unplug a power supply from the lamp so I made a wiring harness our of some standard male and female barrel connectors that I have a bunch of for other LED projects. I designed a press-fit hole for the female connector end and a slot for the rest of the connector wire... it's working fine so far.

This is the first version and I did not quite hit my goal, the bolt is not quite long enough for where the nut trap is and I am apprehensive about making it deeper which would not leave a lot of material between the nut and the clamp bar. In the meantime, I am just using a longer bolt and large washer.

The one I am testing now was printed with 40% infill and 6 layer walls all around.
