Retirees would be advised to stay away from thematic and sectoral funds, including mid- and small-caps. The idea is to generate stable returns rather than focus on high but volatile returns. Debt MFs can also be a part of a retiree s portfolio. Taxation of debt funds makes it a better choice over bank deposits, especially for those in the highest tax bracket.
While interest on bank deposits is fully taxable as per the tax bracket 30. 9 per cent for highest slabincome from debt funds gets taxed at 20 per cent after indexation, if held for three years or more irrespective of the tax bracket. A retiree can consider keeping a significant portion in debt funds also because of its easy liquidity. Tax-free bonds Tax-free bonds, although not currently available in the primary market, can also feature in a retiree s portfolio.
They are issued primarily by government-backed institutions such as Indian Railway Finance Corporation Ltd IRFCPower Finance Corporation Ltd PFCNational Highways Authority of India NHAIHousing and Urban Development Corporation Ltd HUDCORural Electrification Corporation Ltd RECNTPC Ltd and Indian Renewable Energy Development Agency, and most carry the highest safety ratings. One may, however, buy and sell them on stock exchanges as they are listed securities.
Retirees should keep a note of a few things before investing in tax-free bonds. One, they are long-term investments and mature after 10, 15, 20 years. Invest in them only if you are sure that you will not require the funds for such a long period. Second, the interest is tax-free therefore there is no Tax Deducted at Source TDS too. In the last two tax-free bond issues the effective yield, especially for high tax-bracket investors, compared favourably with taxable investment alternatives available at the same time.
Third, liquidity is low in tax-free bonds. Usually, they are listed on stock exchanges to provide an exit route to investors but price and volume quoted at exchanges may play a spoilsport while off-loading them. Last, they usually offer annual and not monthly interest payouts hence may not meet a retiree s regular income requirement. For example, in a declining interest rate scenario, a tax-free bond face value Rs 1,000 with a coupon rate of 8.
3 per cent tax free return may be available in a stock exchange at a price of Rs 1,217, with a yield of about 6. 4 per cent, maturing in 2027 if the investor holds it till maturity. Remember, the interest payouts are at the coupon rate of the bond, i.an investor gets 8. 3 per cent tax free income on his investment and the actual return will be 6. 4 per cent if the bonds are held till maturity. Immediate annuities Retirees could also consider the immediate annuity schemes of life insurance companies.
The pension or the annuity is currently around 5-6 per cent per annum and is entirely taxable. There is, however, no provision of return of capital to the investor, i. There are about 7-10 different pension options, including pension for lifetime for self, after death to spouse and post that the return of corpus to heirs. The corpus is not returned to the investor under any pension option. The immediate annuity may not suit an investor who is capable of selecting and building his own portfolio.
This is also advisable as the returns offered on these immediate annuities are currently on the low side. Post Office Monthly Income Scheme Senior Citizens Saving Scheme bank fixed deposits Immediate annuities tax-free bonds investment news mutual funds investment Tax.the corpus or the amount used to purchase annuity is non-returnable. So it is better to diversify across different investments rather than invest in this scheme if you have the wherewithal to manage your own portfolio.
When it comes to HDTV, more is better. Many people have moved away from standard-definition analog TVs in favor of high-definition HDwhich refers to resolutions of 720p, 1080i, and 1080p. HDTVs offer a 16 9 aspect ratio, which is similar to a movie theater screen, and available with higher-resolution screens, which impress with their clarity, color, and detail.
Resolution is HDTV s biggest selling point. We compared 720p, 1080i, and 1080p to help you make the best choice for your TV viewing pleasure. The 1080p has all but replaced 1080i. You can still find TVs with 1080i screens, but they re less common. Overall Findings. 720p 1080i 1080p 1280 pixels x 720 pixels. 1920 pixels x 1080 lines. 1920 x 1080 pixels. Progressive scan Draws all pixels at once. Interlaced Split into two groups of 540 lines each.
The three HDTV resolutions are 720p, 1080i, and 1080p. The number stands for the number of horizontal lines that create the image, and the letter describes the type of scan used by the TV to display the picture progressive or interlaced. Resolution matters because more lines mean a better picture. This is a similar concept to digital photos and how dots-per-inch determines print quality.
1080i and 1080p are higher resolutions than 720, but they aren t the same. You should go for 1080p because of the more efficient way it projects images onto the screen. Screen Resolution Bigger Is Better. 720p 1080i 1080p 720 horizontal lines. 1080 horizontal lines. Progressive scan. Interlaced scan. In general, the higher the resolution of a TV, the sharper the picture, and the higher the price tag.
720p has an image resolution of 1280 pixels by 720 lines. It was the first available HDTV resolution but is no longer as common since prices have come down on 1080 models. By comparison, a 720p TV has twice the resolution of an analog TV picture. 1080i has a resolution of 1920 pixels by 1080 horizontal lines. However, it is interlaced, so the lines are painted on the screen in two passes of 540 lines each. The picture quality is fine for slow-moving content but not as desirable for fast-moving objects.
1080i was once the standard in HDTVs, but no more. Its quality is not much better than 720p TVs. 1080p has a resolution of 1920 by 1080 pixels, and it is a progressive scan display rather than interlaced. That means each row is scanned in sequential rather than an alternate order, providing a picture with a full liam w iq option. 07 million pixels. This is currently the best-selling TV format, and it provides the best picture of the three models mentioned here.
Price You Get What You Pay For. 720p 1080i 1080p More affordable. More expensive. The price of a high-definition TV varies widely. It depends on many factors, including brand, features, and display technology. The type of display is one part of the hardware. Other factors that contribute to the price include display size, availability of smart features, and screen type LCD or LED.
In general, 720 screens are cheaper than 1080 screens. Within the 1080 tier, progressive-scan displays are more expensive than interlaced. But, depending on the other factors, these comparisons may not always be the case. Assuming all three of these TV formats are in your price range, 1080p TV is the best choice. The 720p and 1080i models rely on old technology that is gradually giving way to higher-resolution options. A 1080p device offers the best resolution and viewing experience.
However, for TVs that are 32 inches or smaller, you won t see much difference between pictures on 1080p and 720p displays. A-Series Gliding Patio Door.

The Raspberry Pi is a wonderful little computer, but one thing it isn t very good at is controlling DC Servo Motors - these motors need very specific and repetitive timing pulses to set the position.
Instead of asking the Pi Linux kernel to send these signals, pop on this handy HAT. It adds the capability to control 16 Servos with perfect timing. It can also do PWM up to 1. 6 KHz with 12 bit precision, all completely free-running. For use with Raspberry Pi Model Zero, ABPi 2, Pi 3, or Pi 4 any Pi with 2x20 header can be used with the Model A or B if you use a tall 2x13 header instead of the included 2x20.
The Adafruit 16-Channel 12-bit PWM Servo HAT will drive up to 16 servos or PWM outputs over I2C with only 2 pins. The on-board PWM controller will drive all 16 channels simultaneously with no additional Raspberry Pi processing overhead. What s more, you can stack up to 62 of them to control up to 992 servos - all with the same 2 pins. Works with any servo that can be powered by 5V and take 3. 3V logic level signals.
Best of all, we even have a Python library you can use, so you ll be up and running instantly, to make your robotic creation come to life. The Adafruit PWM Servo HAT is the perfect solution for any project that requires a lot of servos or PWM outputs. Please check out our detailed tutorial for lots more information including diagrams, schematics, installation instructions and more. Each order comes with a Servo HAT, a 2-pin terminal block, four 3x4 headers and a 2x20 socket header.
You ll need to do some light through-hole soldering to attach the headers onto the HAT circuit board, but its easy to do with basic soldering tools like a soldering iron and liam w iq option core electronics solder. If you would like to stack multiple HATs onto one Pi, you can also pick up a 2x20 stacking header and a set of right-angle 3x4 headers that should be soldered on instead.
This kit does not come with Raspberry Pi, servos, or required 5V power supply. We have recommendations on the required 5-6V power supply on the tutorial page, and a whole bunch of servo options in the Adafruit shop, any 3-pin classic DC hobby servo will work. Also, the terminal blocks included with your product may be blue or black. Dimensions w components 65mm x 56mm x 13mm 2.

meaning, rather than expending effort to build more perfect systems, wrap imperfection-correcting computers around imperfect systems. Back when I was a graduate student, my advisor Tom Knight bestowed upon me many excellent aphorisms. An everyday example of this is the noise-cancelling headphone. Headphones offer imperfect noise cancellation, but by wrapping a computer around it adding one or more microphones and a computer in the from of a digital signal processor DSP the headphones are able to measure the ambient noise and drive the headphones with the exact inverse of the noise, thus cancelling out the surrounding noise and creating a more perfect listening experience.
Although the principle has found its way rapidly into consumer goods, it s been very slow to find its way onto the engineer s workbench. It s the case of the cobbler s children having no shoes. In particular, it s long bothered me that motors are so dumb. Motors are typically large, heavy, costly, power-hungry, and riddled with small mechanical imperfections. In comparison, microcontrollers are tiny, cheap, power-efficient, and could run software that trims imperfections while improving efficiency to the point where the motor microcontroller combo is a win over a dumb motor on almost every metric.
So why aren t we wrapping a computer around every motor and just calling it a day. Then one day a startup called IQ Motion Control showed me a demo of their smart motor, the IQ Position Module, at HAX in Shenzhen. This is the motor I ve been waiting years for. My eyes instantly lit up these guys have done it, and done it in a tasteful manner. Meet the IQ Position Module Simply put, the IQ Position Module is a brushless DC motor that talks serial and thinks at a higher level.
I don t have to design any complicated drive circuitry or buy a proprietary controller that talks some arcane or closed standard. I just plug an FTDI cable into my laptop, hook up power, clone a small git repo and I m good to go. Because of the microcontroller on the inside, the IQ Position Module can emulate a range of behaviors, from a simple stepper to a range of BLDC drive standards, but the real magic happens when you tell it where you want it to go and how fast, and it figures out the best way to get there.
But waityou say, my servos and brushed DC motors can do that just fine, I just control the pulse width. This is true for crude and slow motion control applications, but if you really want to run at high speeds like the ones achievable by a BLDC you have to consider things like acceleration and deceleration profiles. The video below shows what I mean. Here is a pre-production IQ Position Module that s being commanded to turn once in two seconds; then twice, three times, and finally ten times in two seconds.
Notice how the speed ramps up and back down again, so that the motor stops with the figurine in precisely the same position at the end of every cycle, regardless of how fast I commanded the motor to turn. And here s a snippet of the core code used in the above demo, to give you an idea of how simple the API can be. The motor can go even faster, but the figurine I attached on top isn t balanced well enough to do that safely. Just tell it where you want it, and by when and the motor figures out an acceleration profile.
Of course other parameters can be tweaked but the default behavior is reasonable enough. A Motor That s Also an Input Device But wait. Anyone who has busted a geared servo motor by stalling or back-driving it knows what I mean. IQ Position Modules don t have this problem. When you stop driving the IQ module put it in a coast mode it turns freely and without resistance. This means the IQ motor doesn t just write motion it can read motion as well.
Below is a video of a simple motion copy demo I cooked up in about an hour including time spent refactoring the original APIwhere I implement bidirectional read write of motion between two IQ Position Modules. The ability to tolerate back-drive and also go limp is advantageous in robotics applications. Impact-oriented tasks such as hammering a nail or kicking a ball would rapidly degrade the teeth in a geared drive train. Furthermore, natural human motion incorporates the ability to go limp, such as the forward swing of a leg during walking.
Finally, biological muscles are capable of applying a static force without changing position, such as when holding a cup on its sides without crushing it. Roboticists have developed a wide range of specialty actuators and techniques, including series elastic and variable stiffness actuators to address these scenarios. However, these mechanisms are often complicated and pricey.
The IQ Position Module s lack of gearing means it s back-drive tolerant, and it can apply an open-loop force without any risk of damage. This means you could, for example, use it to build a robot arm that can hammer a nail or pick up a cup. Robotic elements built using these would have far greater resilience to motion interference and impact forces than ones built using geared servos.
Having Fun with the IQ Position Module While attending 34C3 back in December 2017, I managed to sit down for about an hour with my good friends Prof. Nadya Peek and Ole Steinhauer, and we built a 2-axis robot arm that could do kinesthetic learning through keyframing, using nothing more than two IQ Position Modules, a Dunkin Donuts box, a bunch of schwag stickers we stole from the FOSSASIA assembly, and the base plate of an old PS4 because fail0verflow. This was improvisational making at its best; we didn t really plan the encounter so much as it emerged out of the chaos that is the Computer Congress.
While Nadya was busy cutting, folding, and binding the cardboard into a 2-axis robot arm, Ole joined lötwat. Because this is a direct drive system, there s no gears to shear. together the power satisfied with the result, she built and stacked a second axis on top. With just a bit of tweaking and prodding we managed to pull off the demo below. It s a little janky, but given the limited materials and time frame for execution, it hints at the incredible promise that IQ Position Modules hold.
So, if you ve ever wanted to dabble in robotics or motion control, but have been daunted by control theory and arcane driver protocols like I ve beencheck out the IQ Position Module. They are crowdfunding now at CrowdSupply. I backed their campaign to reserve a few more Position Modules for my lab by wrapping a smart computer around a dumb motor, they ve created a widget that lets me go from code to physical position and back with a minimal amount of wiring and an accessible API.
Their current funding campaign heavily emphasizes the capabilities of their motor as a better BLDC for the lucrative drone market, and I respect their wisdom in focusing their campaign message around a single, economically significant vertical. A cardinal sin of marketing revolutionary tech is to sell it as a floor wax and a dessert topping as painful as it may be, you have to pick just one message and push hard around it. However, I m happy they are offering the IQ Position Module as part of the campaign, and enabling me to express my enthusiasm to the maker and robotics communities.
I ve waited too long to have a motor with this capability in my toolbox finally, the cobbler s children has shoes. This entry was posted on Monday, March 19th, 2018 at 8 49 pm and is filed under Hacking. 29 Responses to An Intuitive Motor IQ Control s Serial-to-Position Module. This isn t new though, surely. I ve had some of these for years. Hey that s cool, thanks for the link. Out of curiosity, can the Dynamixels work as a zero-force input device too.
Didn t mean to make it sound like this was the one and only but I couldn t resist using the revolution -ary pun. After all, just about everything fundamental to computers was invented in the 60 s, and since then it s just been smaller faster better versions of the same no matter what Intel or ARM want you to think. Iq option 95 perfect signal. In particular, you re correct that almost every servo motor has a microcontroller inside it, even the very simple ones; there has to be some logic to go from pulse width to angle.
I decided not to go into it for the sake of brevity, so I m glad you brought this up in the comments. However, the IQ Position Module is the first consumer-oriented motor module I m aware of that s direct-drive BLDC. Maybe there s others I should be looking at too; I d love to hear all about them here in the comments. I ve used the Dynamixel MX-64 in a platform positioning arm application. It has a high-res absolute encoder 4096 ppr as I recall.
It can go limp, but it s probably a lot stiffer than your BLDC because of the gears. But you also get 1000 oz-in of torque which is nice when moving a 2 lbs target. I m not sure how else you d get real torque for an arm without the gears, fancy controller or not. has a gearbox and are plenty noisy No-load Speed 59 RPM. Hey Joel and all. Yes, these are fairly similar to the Dynamixels. If you go to our Crowd Supply page last paragraph of Bunnie s postand scroll way down, you can see a comparison of some features between an AX series Dynamixel and our motor.
You re right, a number of the features overlap. There are also a handful of new things in the IQ motors. They also fill a space that s right in between stepper motors and smart geared servos like the Dynamixel. The IQ modules have the Dynamixels beat on raw power because much more of the module is motor the part that makes powerrather than gearbox the part that converts power.
They re like apples and oranges. The Dynamixel has the IQ modules beat on torque thanks to the gearboxbut the IQ modules have the Dynamixel beat on speed thanks to the lack of gearbox. They re both fruit, but different fruit. I think the bigger brother of this would be integrated industrial servos like, e.Clearpath motors, which have been around a while. That isn t a knock at all though a more accesible, hobby-sized, Arduino-ized version of those sounds like it d definitely have a big niche.
com odrive A bit different in that it s designed to split the encoder and motor out and drive them separately, but can be talked to in a similar way to use it s own acceleration and planning.
