Mein Bruder hatte heute eine kleine ambulante OP im Krankenhaus. Ihm wurde, ein gutes Jahr nach seiner #Nierentransplantation , der #Dialyse #Shunt entfernt.

Wisst ihr was ein Dialyse-Shunt ist?

So ein Shunt wird operativ angelegt und ein Patient der unter chronischem Nierenversagen leidet wird, über einen solchen 'Anschluss', an die Dialysemaschine angeschlossen.

Motorcycle Regulator By Popular Demand

A few weeks ago we posted a build of an avid motorcycle enthusiast named [fvfilippetti] who created a voltage regulator essentially from the ground up. While this was a popular build, the regulator only works for a small subset of motorcycles. This had a large number of readers clamoring for a more common three-phase regulator as well. Normally we wouldn't expect someone to drop everything they're doing and start working on a brand new project based on the comments here, but that's exactly what he's done.

It's important to note that the solutions he has developed are currently only in the simulation phase, but they show promise in SPICE models. There are actually two schematics available for those who would like to continue his open-source project. Compared to shunt-type regulators, these have some advantages. Besides being open-source, they do not load the engine when the battery is fully charged, which improves efficiency. The only downside is that they have have added complexity as they can't open this circuit except under specific situations, which requires a specific type of switch.

All in all, this is an excellent step on the way to a true prototype and eventual replacement of the often lackluster regulators found on motorcycles from Aprilia to Zero. We hope to see it further developed for all of the motorcycle riders out there who have been sidelined by this seemingly simple part. And if you missed it the first time around, here is the working regulator for his Bajaj NS200.

Motorcycle Voltage Regulator Uses MOSFETs

For how common motorcycles are, the designs and parts used in them tend to vary much more wildly than in cars and trucks. Sometimes this is to the rider's advantage, like Honda experimenting with airbags or automatic transmissions. Sometimes it's a little more questionable, like certain American brands holding on to pushrod engine designs from the '40s. And sometimes it's just annoying, like the use of cheap voltage regulators that fail often and perform poorly. [fvfilippetti] was tired of dealing with this on his motorcycle, so he built a custom voltage regulator using MOSFETs instead.

Unlike a modern car alternator, which can generate usable voltage even at idle, smaller or older motorcycle alternators often can't. Instead they rely on a simpler but less reliable regulator that is typically no more than a series of diodes, but which can only deliver energy to the electrical system while the motor is running at higher speeds. Hoping to improve on this design, [fvfilippetti] designed a switched regulator from scratch out of MOSFETs with some interesting design considerations. It is capable of taking an input voltage between 20V and 250V, and improves the ability of the motorcycle to use modern, higher-power lights and to charge devices like phones as well.

In the video below, an LED was added in the circuit to give a visual indication that the regulator is operating properly. It's certainly a welcome build for anyone who has ever dealt with rectifier- or diode-style regulators on older bikes before. Vehicle alternators are interesting beasts in their own right, too, and they can be used for much more than running your motorcycle's electrical system.

#Paraclimbing #Baumklettern
Ich habe mit dem Klemmgerät #Shunt im Baum weiter herumexperimentiert.
Ich habe endlich herausgefunden wie ich ihn ähnlich wie LockJack aus der #Baumpflege nutzen und unter Last lösen kann. Ich habe dafür die grüne feuerfeste Reepschnur gewählt.
Das ist die Ziehschnur zum lösen. Bremsen geht mit der anderen Hand. Ich habe ein Doppelseil-Flaschenzug-system, also bremst es genug zum abseilen.
Und ich mag es gern "runter zu schießen " gaannnzzz schnell!

Aufstieg geht so auch super, kaum Belastung für die #Rheuma kranken Gelenke

Ich habe mit dem Shunt diese Versuche gemacht, weil ich gern auf klassisches Halbstatik Seil wie mit Lockjack klettern wollte. Lockjack ist aber teuer und geht nur auf Baumpflegeseile.

Natürlich klappt es ansonsten auch mit Klemmknoten und zwar flexibler auf allen Kletterseilen. Aber mit dem Shunt war es auch nett, weil er am Seil fast reibungslos hoch geht.

Piezo Pickup Makes Wax Records Easy to Digitize

Sound recording and playback have come a long way in the last century or so, but it's fair to say there's still a lot of interesting stuff locked away on old recordings. Not having a way to play it back is partly to blame; finding an antique phonograph that plays old-timey cylinder recordings is pretty hard. But even then, how do you digitize the output of these fragile, scratchy old recordings?

As it happens, [Jan Derogee] is in a position to answer these questions, with an antique phonograph and a bunch of Edison-style wax cylinders with voices and music from a bygone era locked away on them. It would be easy enough to just use the "reproducer" he previously built and set up a microphone to record the sound directly from the phonograph's trumpet, but [Jan] decided to engineer a better solution. By adding the piezo element from an electronic greeting card to his reproducer, potted with liberal quantities of epoxy and padded with cotton, the piezo pickup was attached to the phonograph arm in place of the original stylus and trumpet. The signal from the piezo element was strong enough to require a shunt resistor, allowing it to be plugged directly into the audio input jack on a computer. From there it's just an Audacity exercise, plus dealing with the occasional skipped groove.

We appreciate [Jan]'s effort to preserve these recordings, as well as the chance to hear some voices from the past. We're actually surprised the recording sound as good as they do after all this time -- they must have been well cared for.
