However, with a smaller dust bin compared to other models on the market and no app control or integration with voice assistants, there are some compromises to be made for the low price - although that will be music to the ears of those that want a simplistic robot vacuum. It’s slim, too, meaning it has no problems cleaning under furniture with low clearance. On test, it picked up dry oats from a medium-pile carpet and a hard floor with ease, and finer dust made from flour and cookies was also no problem for it on a hard floor - although it wasn’t as good on carpets. That’s not to say the affordable price tag means compromising on dust pick-up. At a reasonable price and often discounted, you’ll be hard pushed to find anything cheaper on the market. The best robot vacuum 2023: tried and testedįor those seeking a robot vacuum on a budget, the Eufy 11S is worth considering. We've tested all their key features – runtime, suction power, mapping and automation capabilities and more – in real-world situations to help you find the best robot vacuum for you and your home. So to ensure you get the most vacuum bang for your bucks, we've tested the leading models to really put them through their paces – and we've tested them in our own homes, which are much more challenging than any test lab. Some of the best robot vacuums can be quite expensive, although as with all tech the prices do come down over time. However, for everyday, effortless cleaning, robot vacuums are brilliant things. In that latter case we'd recommend investing in one of the best robot vacuum cleaners for pet hair instead, because they're made specifically for cleaning up after your four-legged friends. We love robot vacuum cleaners, but in some cases we wouldn't recommend them as alternatives to the best vacuum cleaners if you have very messy kids, LEGO-strewn rooms or very hairy pets. Some can even detect when they're moving from hard floors to carpets or rugs and adjust their cleaning power accordingly. And they have clever navigation systems to ensure they don't miss an inch or vacuum up a lost sock. They're smaller and more powerful, delivering better cleaning with a lot less noise. Even the most affordable robot vacuums are packed with cutting-edge tech.

If this couple were ever to get separated in the future, when they reunite, they can piece the two halves together, and the completed hairpin would serve as a proof of their identities as well as a symbol of their reunion. During the wedding ceremony, some Chinese couples exchange a lock of hair as a pledge, while others break a hairpin into two parts, and then, each of the betrothed take one part with them for keeping. In Han culture, people call the union between two people jie-fa ( Chinese: 結髮), literally "tying hair". Hair has always carried many psychological, philosophical, romantic, and cultural meanings in Chinese culture. After the wedding ceremony, the husband should put the hairpin back into his spouse's hair. At the time of an engagement, the fiancée may take a hairpin from her hair and give it to her fiancé as a pledge: this can be seen as a reversal of the Western tradition, in which the future groom presents an engagement ring to his betrothed. While hairpins can symbolize the transition from childhood to adulthood, they were closely connected to the concept of marriage as well. In the 21st century hanfu movement, an attempt to revive the traditional Han Chinese coming-of-age ceremonies has been made, and the ideal age to attend the ceremony is twenty years old for all genders. In comparison with ji li, the male equivalent known as guan li ( Chinese: 冠禮) or "hat initiation", usually took place five years later, at the age of twenty. However, if a young woman had not been consented to marriage before age twenty, or she had not yet participated in a coming of age ceremony, she would attend a ceremony when she turned twenty. This practice indicated that these young women could now enter into marriage. When they turned fifteen, they could be considered as young women after the ceremony, and they started to style their hair as buns secured and embellished by hairpins. Particularly, before the age of fifteen, girls did not use hairpins as they wore their hair in braids, and they were considered as children. This ceremony marked the coming of age of young women. In Han Chinese culture, when young girls reached the age of fifteen, they were allowed to take part in a rite of passage known as ji li ( Chinese: 筓禮), or " hairpin initiation". Furthermore, hairpins worn by women could also represent their social status. In ancient China, hairpins were worn by men as well as women, and they were essential items for everyday hairstyling, mainly for securing and decorating a hair bun. Hairpins (generally known as fa-zan Chinese: 髮簪) are an important symbol in Chinese culture. Gold phoenix hairpin found in the Ming dynasty tomb of Prince Chuang of Liang (梁莊王, 1411–1441), 15th century. The kinks enable retaining the pin during normal movements.Ī hairpin patent was issued to Kelly Chamandy in 1925. The length of the wires enables placement in several designs of hairstyles to hold the nature in place. The finished pin may vary from two to six inches in last length. Some hairpins are a single straight pin, but modern versions are more likely to be constructed from different lengths of wire that are bent in half with a u-shaped end and a few kinks along the two opposite portions. The hairpin may be decorative and encrusted with jewels and ornaments, or it may be utilitarian, and designed to be almost invisible while holding a hairstyle in place. Major success came in 1901 with the invention of the spiral hairpin by New Zealand inventor Ernest Godward. Such hairpins suggest, as graves show, that many were luxury objects among the Egyptians and later the Greeks, Etruscans, and Romans. Hairpins made of metal, ivory, bronze, carved wood, etc. The creation of different hairstyles, especially among women, seems to be common to all cultures and all periods and many past, and current, societies use hairpins. The earliest evidence for dressing the hair may be seen in carved " Venus figurines" such as the Venus of Brassempouy and the Venus of Willendorf. It may be used simply to secure long hair out of the way for convenience or as part of an elaborate hairstyle or coiffure. A golden double-spiral-headed pin from Georgia (3rd millennium BC)Ī hairpin or hair pin is a long device used to hold a person's hair in place. Then you use an open collector driver (which can be just an NFET) with a resistor on the output to pull down each PFET gate when you want to measure. You put a PFET with source connected to each cell positive, and a source-to-gate resistor in parallel with a ~8V zener diode. One way is to apply a high side switch to each divider. (to be clear none of these are "good" in terms of being a professional/production solution) Sure there are a couple of solutions here. Thanks a lot for reading, I am sorry, if i have fogotten something essentialĮDIT: I hope this is the right sub, sorry if not! I just now could not find a alternative online, that does not use a voltage divider.Īs far as I understand, the voltage devider was crappy calculated, with a much so low resistance, so the cells got sort of shorted out, or the resistance of the voltage divider added to the internal resistance, so that the cells discharged just though the voltage devider. Is there a clever way to read out the individual voltages of the cells, without discharging the cells? Or is it working in theory, but the resistors were calculated poorly? How ever, I just wanted to continue the project, but the first two cells were discharged to about 1.5 or 1 V, so beyond recharge. It worked, but I broke the display, so I had to wait for a new one to arrive and I did not take out the cells. I had help of a friend, who studies something electronic related and he gave me the hint to use a voltage divider, to pull down the voltage enough for the arduino to handle (I calculated it with about 4.5V, and adjusted the values in the code, to match the measured voltage). I checked the voltage of the individual cells after letting it rest for a while, and the voltages seemed to be fine. You can try and see what happens with the simple resistor solution, might work and be okay, but I wanted to show you an alternative.I started a Li-Ion 18650 battery-project for a diy-bluetooth speaker this summer, but only reacently got around to continue working on it. Compared to the 2.2♚ maximum drawn by VBAT domain, this is not too heavy of an impact.ĭownside is of course the added complexity on the board, you need another pin to switch the battery to the ADC and the costs. It provides a nice low impedance path to measure the voltage for the ADC. In the end we are looking at 150nA maximum, 12nA typical at 25☌ additional drain from the battery with this analog switch. And it turns out to be really low, a maximum of 50nA over the whole temperature range. In the datasheet this corresponds to \$I_\$). So the chip is powered and we are looking for the leakage current of the NO-pin. In this state only the supply current and the leakage current of the NO-pin is draining the battery (and of course the VBAT domain of the STM32). It's a bit tricky to get which number we are looking at, so let me first explain how I'd wire the thing up:Īs soon as you power down the microcontroller, the pulldown resistor will ensure that the analog switch flicks to the normally closed pin, which we tied to ground with another 100k resistor, so it doesn't float. Next thing we want to watch out for is leakage current of the inputs, which might be higher than the supply current in this case. Only a maximum of 100nA over the whole temperature range (careful which supply current condition you look at in the datasheet, I'm referring to the 3.3V pages). The supply current for this part is really low. A look in the datasheet shows, that this is indeed the case. Now, as it is an IC, it will most likely be specified in a similar way than a microcontroller, that no input shall be above the supply rail. Something like a TS5A3160 from Texas Instruments (there are lots of alternatives available, this will probably not be the best part available). So can we do better?įirst thing which comes to mind is using an analog switch. Now measuring the battery with a 1MegOhm resistor is not the best idea, it's easy to get distortions and you have to be careful to select a long enough sampling rate to charge the sampling capacitor. It will be less, but predicting how much is a bit difficult. With this setup you limit the maximum current to be at most 3♚. Simulate this circuit – Schematic created using CircuitLab So it would lead to an excessive current draw on you backup domain.Ī simple solution might be to put a large resistor in series. If you were to connect the VBAT directly to another pin of the STM32 and turn off the main power supply, the protection diodes would start conducting and try to power the STM32. The problem arises as soon as you power off the microcontroller. Sadly the STM32F103 series does not offer an internal ADC channel connected to VBAT, so you have to connect it externally.

In addition, you will get more value because the price is nearly half of what other big carriers offer. The fourth plan brings along unlimited data. If that’s the case, the unlimited plan should be high on your list. It’s more than enough for most people but will hardly do the trick if you are a heavy user. It’s the largest amount of data you will get from Mint Mobile. We can say the 15GB data plan is a bit more generous. But keep in mind, a 10GB data allowance is still not enough especially when you like streaming videos. Therefore, upgrading to this plan makes more sense for the users who want more flexibility. It costs only $5 more than the basic plan. The 10GB data plan is more like the middle ground between the amount of data and price. See also Will Mint Mobile Get 5G - How Much Will It Be?

Strong acid solutions have PH’s that go “below” the standard 1-10 scale, so by the time you neutralized a strongly acidic AuCl solution to a PH of 1.9, it is out of the strong acid range and thus practical for ppt with SMB.ĭISCLAIMER: Material presented on the 911METALLURGIST.COM FORUMS is intended for information purposes only and does not constitute advice.

The recovered beautiful yellow AuCl solution is then evaporated to remove excess HNO3 and reconstituted with H2O, monitored with electronic PH /MV meter to ensure a PH of at least “above 1.9” - then finally subject to SMB ppt. Finally, the undisturbed washed-ore - while still remaining in the fritted filter - is then directly subjected to “very hot” AR soln. Even though using G4 fritted filter, microscopic Au gets through with the boiling water and precipitates on its own in the filtered H2O below. The HNO3-washed ore - while remaining in the fritted filter - is then cleansed with boiling H2O. Our lab works microscopic Au, Pt, Ir recovery from desert ore and our standard procedures follow at least two HNO3 washings through fritted glass micropore filters (so not to wash away microscopic Au particles). Regardless of how much gold might be present in our ore, unless the aqua regia (recommended over HCL & Bleach when dealing with ore rather than jewelry scrap) can freely react with the gold present, we will spin your wheels and get “consistently inconsistent” results that will drive us crazy.

The direction that these wavefronts (straight-line crests) are traveling through the water is represented by the blue arrow. The diagram at the right depicts a series of straight waves approaching a long barrier extending at an angle across the tank of water. These waves will travel through the water until they encounter an obstacle - such as the wall of the tank or an object placed within the water. As viewed on the sheet of paper below the tank, the crests are the dark lines stretching across the paper and the troughs are the bright lines. These straight waves have alternating crests and troughs. If a linear object attached to an oscillator bobs back and forth within the water, it becomes a source of straight waves. Ripple tank demonstrations are commonly done in a Physics class in order to discuss the principles underlying the reflection, refraction, and diffraction of waves. As the waves encounter obstacles in their path, their behavior can be observed by watching the movement of the dark and bright spots on the sheet of paper. As the water waves move through the ripple tank, the dark and bright spots move as well. So the bright spots represent wave troughs and the dark spots represent wave crests. A crest of water will absorb more light than a trough. A portion of light is absorbed by the water as it passes through the tank. A light typically shines upon the water from above and illuminates a white sheet of paper placed directly below the tank. A ripple tank is a large glass-bottomed tank of water that is used to study the behavior of water waves. The study of waves in two dimensions is often done using a ripple tank. But what if the wave is traveling in a two-dimensional medium such as a water wave traveling through ocean water? Or what if the wave is traveling in a three-dimensional medium such as a sound wave or a light wave traveling through air? What types of behaviors can be expected of such two- and three-dimensional waves? Specifically, there will be some reflection off the boundary and some transmission into the new medium. Rather, a wave will undergo certain behaviors when it encounters the end of the medium. The wave doesn't just stop when it reaches the end of the medium. Previously in Lesson 3, the behavior of waves traveling along a rope from a more dense medium to a less dense medium (and vice versa) was discussed.
