This strap tensioner is an add-on to my theft protected strap buckle.

If you don’t have the theft protected buckle yet, you can find it on my main publication page:
https://www.printables.com/model/565652

The strap tension that is published here, is needed to hold the loose ends of the strap together and adjust the length of the strap to your needs.

Happy printing!

If you have to many drill bits. I sort all close diameters together. And use calipper to determine the exact diameter. For example in the department marked with number 8 i have every drillbits 8-8.9 mm. Clear?

I recommend to print several stems at one time and use external brim connecting items to one. No supports required.

You can join cane stem with different flowers or custom heads. I’m going to make some, like ear of corn or reed panicle.

This week’s EYE ON NPI (video) is switching it up, with a look at some high-voltage-capable analog switches – Texas Instruments’ TMUX821x Flat RON SPST 4-Channel Switches.

A simple and effective way to switch and control up to 4 x 100V connections with up to 200mA each from any microcontroller or microcomputer.

We carry dozens of different switches, and DigiKey stocks easily 50K different switch configurations from push-buttons to toggles but all of these require a person to push the button mechanically, whereas the TMUX series will connect and disconnect based on a separate digital signal, as low as 1.8V and as high as 48V.

These are often used for switch audio or video, but are also often used in sensor measurement or test equipment. They’re not good for power supply switching, and for digital signals there’s often other ways of moving signals around, although they are sometimes used for the data lines of bidirectional digital signaling systems like USB.

Like mechanical switches, the TI TMUX family of analog switches are ‘bidirectional‘ – that means you can pass signal from A to B or from B to A. However, unlike mechanical switches, there is no, well, mechanical connection. Instead, the switches are created by putting N-FET and P-FET transistors back-to-back. This means that there is no switch-bounce or contact oxidation.

Analog switches are pretty magical, and solve design problems that involve moving an analog signal around without having to hand-build a switch on board, but there are a few things to watch out for when ‘modeling’ how an analog switch varies from a mechanical one!

First up, analog switches have fairly low ‘Ron’ resistance when the analog switch connection is made – on the order of a few ohms – and that is much higher than a mechanical switch. There is also ‘very very high resistance, but not an open-circuit’ when the analog switch connection is broken – on the order of a few hundred mega-ohms.

And don’t forget you will need to have positive and negative power supplies beyond the voltages switched. So, if you are trying to switch 24Vpp signal, that ranges from -12V to +12V, you will need to supply them on the VDD and VSS lines. Also these are not electrically isolated, so add a separate opto/digital isolation circuitry if you want to keep your microcontroller fully disconnected from any high voltages.

But compared to classic jellybean analog switches like the CD4066, the TI TMUX series of analog switches have improved circuit protections that will keep you from popping your chips by accident – especially since this series can be used with up to 100V. Check the datasheet for all details, but highlights include: built in pull-down resistors, protection against over/undervoltage as well as out-of-order voltage application, and latch-up immunity.

If you’re looking to switch up some analog signals on your next design, check out the Texas Instruments’ TMUX821x 4-Channel Analog Switch family with 3 different configurations of NO/NC. And all are in stock for immediate shipment from DigiKey! Order tonight and by tomorrow morning you will be switchin’ and swatchin’ with these low Ron SPST analog switches.

You can now use the SGP40 Air Quality Sensor with Adafruit.io WipperSnapper to acquire pressure measurements, without writing a single line of code! 

More about the SGP40 Air Quality Sensor:

*sniff* *sniff* … do you smell that? No need to stick your nose into a carton of milk anymore, you can build a digital nose with the SGP40 Multi-Pixel Gas Sensor, a fully integrated MOX gas sensor. This is a very fine air quality sensor from the sensor experts at Sensirion, with I2C interfacing so you don’t have to manage the heater and analog reading of a MOX sensor. It combines multiple metal-oxide sensing and heating elements on one chip to provide more detailed air quality signals.

What is WipperSnapper?

With Adafruit.IO and WipperSnapper Firmware, you can effortlessly connect various components and sensors to any of the 20+ supported development boards to build an internet-connected electronics project. The best part is that you can configure and control these sensors from the web using Adafruit IO, all without the need for programming.

Read this guide for instructions on using a device WipperSnapper with the SGP40 Air Quality Sensor >>>

You can now use the LPS22 Barometric Pressure and Temperature Sensor with Adafruit.io WipperSnapper to acquire pressure measurements, without writing a single line of code! 

More about the LPS22 Barometric Pressure and Temperature Sensor:

This absolute pressure sensor, ST LPS25HB can quickly and easily measure this air pressure, useful when you want to know about the weather (are we in a low pressure or high pressure system?) or to determine altitude, as the air thins out the higher we get above sea level. For example, at sea level, the official pressure level is 1013.25 hPa. You can use this sensor to measure the current pressure where you are right now, to compare.

You can now use the INA219 High Side DC Current Sensor Breakout with Adafruit.io WipperSnapper for acquiring precise current measurements, without writing a single line of code! 

More about the INA219 High Side DC Current Sensor Breakout:

This breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can just use the handy INA219 chip on this breakout to both measure both the high side voltage and DC current draw over I2C with ±1% precision.

Real-time flood sensors were developed by the FloodSense project at NYU and the CUNY Advanced Science Research Center (ASRC), with a goal of providing information on the presence, frequency, and depth of hyperlocal street-level flood events to a range of stakeholders, including policymakers, government agencies, citizens, emergency response teams, community advocacy groups, and researchers.

Design goals:

• Low-cost
• Multiple use cases
• Open source

The current iteration of the sensor consists of a low-power microcontroller with integrated LoRaWAN radio, a 2200 mAh battery, a solar controller and 1.2W solar panel, and a Maxbotix industrial grade range sensor.

Read more on FloodNet here.

Today I ran across a battery in DIP (breadboard friendly) packaging. The surprising thing is it’s powered by tritium, a radioactive isotope of hydrogen. I first heard of nuclear batteries decades ago (tiny ones vs. large nuclear plants used in deep space exploration).

There can be obvious benefits to use in aerospace, defense, medical, and other industries. They can operate in harsh environments (-55°C to +150°C) and operate for 20 years or more. They use a semiconductor and beta decay to generate a voltage.

NanoTritium™ batteries are used to keep encryption keys alive in static random access memory (SRAM) for more than 20 years in digital processors, such as field-programmable gate arrays (FPGAs). These keys are maintained in SRAM volatile memory while the FPGA or processor is powered down. The NanoTritium™ battery maintains power to the SRAM even in harsh temperature environments. This is a benefit over conventional batteries that are chemical based (e.g., lithium, NiCad, etc.)

Yes they are radioactive but sealed. The shocker, really is the price – they start at US $5,250 per battery and go up based on size.

You can read more at citylabs.net. Via Bluesky.

Every week we’ll 3D print designs from the community and showcase slicer settings, use cases and of course, Time-lapses! This Week:
