The Eyeque Insight Lite Vision Screener

This company, Eyeque, is situated to provide the user , those responsible for Home Health Care or others in the field with a simple way to check vision between visits to the eye doctor or those (on a global scale) unable to get to a vision screening facility. This is only one of their products. It”s at an entry level price. I’m currently evaluating for myself, this product, but with the first completed test, it gave me some numbers on the status of my vision from the comfort of my home. More, later. Yes we are assuming you have a the required smart phone specifications by Eyeque for this device.

Addendum 10/11/22

I’ve used the Eyeque Insight Lite a few times. There were some issues with compatibility with smartphone devices used and there is a required set of specifications as to the smartphone’s requirement.. Best results was with the Xiaomi MiMax3, the EyeQue Insight has specific browser requirements as it’s not an app per say (this may have been changed) but a web address so the browser requirement is a software requirement.

“read the instructions…DUH” I’m one of those who occasional assume that a smart device or app will give out all the pertinent information and error checking when it operates. Storing your results int he cloud only works when you are logged in (multiple accounts possible) . Once up and running there maybe a slight lag registering the finger swipes (indicating the direction of the “E”, each successive indication of a finger swipe has an audio indication and it advances to the next display of the “E”, some may be more than one “E” visible. When you can’t distinguish the direction of the decreasing size of the “E” you press the blue button marked “I’m not sure”. The tests shortly concludes and the results are given such as 20/50 etc. for each one of both eyes. The contrast test is similar and displays a varying shade of gray “E” for your contrast test and grades the results on 3 scales Low , Medium and High. I’ve noticed the contrast test is more pertinent than the acuity test.

Do you really need this device one would ask? It is possible to get your own printed eye chart and do the test (in a properly lighted room) and there may be other testing available online with a desktop monitor (properly calibrated). The EyeQue Insight stores the results and can easily work at any location. Could be used in the field (with a smartphone) where access to a chart or computer is not available. Also unsure if the app or webpage used can operate without a cell/wifi connection active.

One other note, any measurement taken at a given time is not the same, in Metrology, an certifiable measurement may be the average of several readings and/or readings taken by more than one person or more than one source. The readings are valued for an average and a certain +/- range of a measurement is certified. Basing any conclusion , especially in the health care field, on only a few readings, may be inaccurate or lead to inaccurate results and conclusions.. Given the size of datasets that my be collected in the cloud, accuracy may be increased if a measurement is compared to a data set collected in the cloud.

ADDENDUM 10/11

Also not shown, Google Pixel 3 running Zep Life app. Workout selected for walking gives fairly good results just having the phone in my pocket. But possibly the updating of the GPS make it appear that you are walking around if the phone is stationary. I”ve kept the app running during the day without a lengthily walk and racked up mileage and steps.

Considering a fitness band addition in the future. Weight can be logged in to the Zep life app if you don’t have a smart scale but a smart scale would be a good addition to consider. It would be nice to have the Zep app allow you to manually enter blood pressure, pulse and temperature. Presently I use a notepad app.

You see where this is going for home health care and a more independent assessment of one’s health at their own frequency and convenience and that an average of several readings is better than a single snapshot of parameters.

ON THE BENCH, QUICK AND EASY BLUETOOTH ADAPTER CABLE

A BLUEMAT GROUP MEMBER SERIES

SOONER OR LATER IT’S APPARENT WITH ALL THE SMART DEVICES AROUND AND STREAMING SERVICES AVAILABLE IT’S A HASSLE TO EITHER GET THE CORRECT HOOKUP CABLE, AS EVEN THE STANDARD 3.5 MM OUTPUT JACK IS DISAPPEARING, TO CONNECT WITH A DEVICE, USUALLY RETRO AUDIO DEVICE THAT HAS THE TYPICAL LINE INPUT (RCA TYPE LEFT AND RIGHT OR 5MM 3 CONDUCTOR JACK).

IF YOU HAVE A BLUETOOTH SPEAKER , NO PROBLEM PAIRING UP. ON THE BENCH I USE THE SMARTPHONE DEVICE WITH THE PROPER APP AS A FREQUENCY GENERATOR FOR TEST PURPOSES OR JUST WANT TO HAVE MY PLAYLIST AVAILABLE TO PLAY THROUGH AN ITEM I’VE REPAIRED THAT DOESN’T HAVE BLUETOOTH INPUT PAIRING AVAILABLE.

ALL THAT’S NEEDED IS A SIMPLE INEXPENSIVE BLUE TOOTH MODULE WITH SOME AUDIO CABLES FROM THE SCRAP BIN AND A 120 VAC TO 5 VOLT DC SUPPLY WHICH OVER THE YEARS ARE ACCUMULATED ON THE SHELVE.

THE MODULE:

MH-ET LIVE MH-MX8 MP3 Decoder Board Bluetooth 4,2 Audio Modul Verlustfreie Stereo DIY Refit Lautsprecher Hohe Fidelity HIFI

M18

US $1.29×4

from Ali Express (no longer available from this store) there are others available

The schematic , actually you just need a power supply and a method to get the output to your audio device. I skipped the rest. Also this could be portable with the proper VCC battery setup. The amplifier is shown but not included.

The Car: The Rise and Fall of the Machine that Made the Modern World [Kindle Edition]
By: Bryan Appleyard

There are those that portend that the transportation industry is about to change in radical way. Our former relationship with the automobile and it’s supporting industries is drastically being challenged. The love of our life will be a simple utility.

Before I comment, a moment of reflection. In today’s world consider any object including people.

Now that object is in a place. Consider the following.

Does object need to be moved?

How much energy is required to move that object.?

A totally cold assessment of transportation , I agree. but to some analyst that is the end game, a zoom out view of what needs to be considered in today’s world when every aspect of our lives may be quantified by cost, carbon footprint, environmental impact and safety.

Now back to the book.

This title caught my eye as electric vehicles have stirred such a frenzy like a poked hornets nest.

The haters have mounted a campaign in a last ditched effort to prove that the electric vehicle is a pipe dream concept and has no benefit over the ICE vehicles that we were taught to love. But the fact that a set amount of energy can only be extracted from a gallon of gas was a nail in the coffin of the Internal Combustion Engine no matter how “clean” it was. Other technologies could be improved many times.

From first hand experience, cars were a freedom to leave the nest, I bonded many friendships over grease and oil soaked clothes, grimy hands and tools. It was a benefit as far as the learning experience. I never attended any structured automotive education. We learned mechanical engineering by turning this or that and disassembling, modifying and repair as a way to afford our wheels. At the time our effort, time and labor didn’t get considered. For our generation and demographic the automobile was an escapism, a hobby and for some the calling to a career.

Later in life I came to question the allure of the automobile. No longer did I want to be prone, face up under a vehicle. It became a futile effort expending time and money to fuel, repair, insure, register and maintain this form of transportation. It was a point in life I didn’t have the need for transportation to get me to a physical location for employment.

One of the pivotal moments of transportation (and briefly mentioned in the book) was the birth of ride hailing. Amazing is the fact that it did not require a retooling of any sort. It was born from, as in my opinion we will see more of this, a stitching and marriage of software technology. Financial software gives us the ability to eliminate any sort of physical exchange of paper currency. Billing and payment is seamless with the service. Employment software let these services hire and manage the workforce of available drivers, a subset of the existing gig economy. Finally, mapping software and tracking allows instant , or close to it , on demand transportation from any point A to any point B. Quietly underrated this was in my opinion one of the greatest disruption and an option to the complex and increasing expensive mechanical contraptions that sit in our driveways. A direct counter culture to the heart of the Automotive Industry.

Purchase and ownership of the automobile is now not required.

This all combined to give the user a safe, up to date well maintained vehicle and vetted driver at their whim. The naysayers balked , taxis seemed to disappear from the landscape overnight. As with all technology it will evolve with the addition of electromechanical revelations and increased computer power, the driver will be removed from the equation.

This book goes into detail of the history of the automobile. From inception to it’s present state. It’s a bit thin on present but the author has laid the groundwork to make his point. The shift from horses to self powered vehicles was equally disturbing and disruptive to the way of travel and business. No one today mentions that we were at a time almost knee deep in horse shit or the pollution, disease and damage it caused.

The author brings up another lesser know fact that the expansive infrastructure required that followed the development of the automobile changed the landscape dramatically, the haters of the time rejected the idea of the proliferation of the automobile and it’s required infrastructure as it would be an ecological disaster waiting to happen. DID IT ?

So was the relationship of the automobile in our lives a grandiose effort to support the automotive and associated industries?

All in all, to me an interesting read The Car: The Rise and Fall of the Machine that Made the Modern World is yet to have the final chapter written. It’s about to unfold.

Addendum 10/02 :

Will part of the final chapter be that we are still being catered to as far being sold a device we don’t need? Is the illusion that the transportation we need is still a necessity of boasting ownership of speed, luxury and a status symbol we display ? How will industries react to a vehicle that does not require a driver and accidents are reduced to nearly none? Will signs be erected that read ” Autonomous vehicles only beyond this point” ? Perhaps the signage will be barcodes for the vehicle own sake.

The basic cookie

A reblogged recipe, as I often look up my own recipes , quick and easy to do cookie recipe repeated yesterday. I processed these in the food processor. A more homogeneous mix result also very crispy. This is 1/2 the recipe , the rest in the fridge for a future bake. I would cut back on the time of 13 minutes at 400 degrees farenheit. Good goto snack

Metro Blog

Not a big fan of cookies , but somehow it’s necessary to get chocolate incorporated into your diet. Another requirement, a simple recipe.

How about a one bowl, no mixer required. just the use of your hand(s) recipe.

Don’t actually recall how I found this recipe, possibly a twitter link but whatever some conversion from grams to ounces was required and maybe some translation if your not up on your french.

First the method:

Cut up the butter

Add the sugars, mash together with your fingers

The egg….

The flour….

Mix with your fingers again…

Mix till incorporated….

until it forms together…

for ease of division, form into logs….

Divide as to how large you want the cookies

Place on the cookie sheet flatten slightly, and bake..

Voila !

 

OK ! enough pictures ?

Now the particulars, by the way this is the second recipe, as I cut back…

On the bench.. VTVM Test probe kit.

This a continuation of the repair and restoration of a Simpson 303 VTVM.

The Blue Mat Group Member Series

ON THE BENCH: Vintage Simpson Model 303 Analog Vacuum Tube Volt Meter – UNTESTED

The final decision was to purchase this kit. $21.35 seemed pricey but the alternative was to scrounge around for parts and/or order the balance of parts I didn’t have. Considering what i would have to do and I wanted to get this job up and running to have as my main meter, I placed the order (eBay).

After receiving this kit I realized that this was the better choice. The coax cables were just the right size and flexible. The other included test lead wire quality matched to boot. All the parts needed were there , no need to raid the parts bins. Plus I would have some parts left over for the parts bins.

The kit, great packaging, recyclable for parts storage or use as seller packaging.

The meter waiting to be completed, My combo LED fluorescent bulb lamp in the reflection.

un boxing or un bagging

attention to detail even a Velcro loop is included.

A quick view of the eBay listing, the seller had pictures that answered all my assembly questions. The finish for this project had been on the back burner for weeks. Retrieved the parts bin, now where did I put that ? (mushroom container) for the repair to get the male parts of the connectors. Now where’s the schematic?

It was the normal start at the bench , prep the soldering iron ,replacing a piece. Then locating the schematic to the meter to verify the placement of the inline resistor to the correct probe and available for troubleshooting if required.. Assembly is straight forward, first I assembled the grounding lead, no problem soldering. The seller specified by pictures , 3 inches of stripping for the coax cables. The hardest part is the fishing of the inner conductor down through the probe handle and out through an angled bore at the end of the probe handle in the metal tip.

R29 1 megohm resistor in the probe, supplied by the kit.

schematic , most of it is the multiple decks of the multi layer rotary wafer switches

replacing the barrel sleeve on the iron.

cross section of the supplied wire from the kit

Once through, some of the stripped wire is pulled through and the probe trim ring is screwed to the top of the probe tip, locking the wire in place and making the connection.

The second time around for the second probe, was problematic, The center conductor was tinned,. After repeated ( time consuming) failed attempts, I fished a length of thin wire solder up from the tip and tacked the center conductor lead to it. Acting as a fish tape, I simply pulled the solder wire through. The wire followed !. Done with the probe set , nice. It’s a bit frustrating and time consuming fishing wires but the probe handles are permanently attached (as i first tried to unscrew them) so they won’t unscrew and loosen as another set I have does frequently. The completeness of the kit even includes labels for the probes and transparent heat shrink . Well Done !

The 1 meg ohm resistor soldered to the center conductor

the angled bore at the top of the probe tip.

using the solder wire as a wire puller

No problem, a time saver I should have used at the start.

tinned lead

folded back for connection to the male coax connector

I soldered the shield braid to the metal bushing

The completed connection less the outer part of the connector

The outer part just screws on with the nut, backed up the small cable with a few layers of shrink tubing.

The completed male end of the probe lead

On the other end the wires had to be stripped to connect the lead to the coax connector, supplied by me as I replaced the original connectors on the meter when rebuilding it. those male connectors are not available and not included when I bought the meter.

.At first the leads did not work ! Guess what ? The first tech help question “is the unit plugged in” applied. Duh..

Another problem was that on the ACV/ohm , the ohms reading was shorted and not reading. The problem was that the cable braid was shorting to the center conductor after the connector was assembled. I trimmed back the braid, it;s not necessary to connect it at the coax end of the lead.

A final check of the meter was done now and revealed that any AC voltage readings were not properly registering . Ouff! Troubleshooting time. Was the rectifier tube faulty? The tracing reveled an error either in the wiring or a crazy schematic.

Now the time began to fly. Mistakes by tracing the schematic wiring from one page to another lead me down a path that cost time. I pulled the stapled schematic paged apart folded them and joined the pages to indicate the correct path from one page to another. One problem solved. Now a broken wire to nowhere was found from one of the wafers . With the proper tracing, it was discovered that one of the capacitors replaced was in error, going to ground instead of going to the probe connector and to the tube.. Most of the tracing of this device is done by tracing layers of selector switches connected to banks of resistors. Keeping my fingers crossed the meter was plugged in and set to measure AC line voltage. Voila ! Success. Luckily the mistake did not damage the meter when I checked it with 120vac previously.

All in all, including making a cup of coffee break , the bench time was from 13:10 to 18:03 . Taking my pleasurably time with soldering and troubleshooting was worth it. The meter is now ready to go as the humidifier repair is next on the bench.

Now with the purchase and rebuilding of the meter and the probe kit the best part, of course is the use of an analog meter, a Simpson. I would do the required Happy Dance, but I don’t do dances.

1 megohm reading

Final AC line voltage test , before calibration

The coax connections offers better shielding when you need a accurate reading of low ac voltages and the proper isolation for high voltage readings .

5 stars for the kit, those who frequently order parts know the time that’s involved if one had to do all the working ordering all the parts included in this kit.

EASY AND QUICK (FOOD PROCESSOR) CAKE BITES

NOT EXACTLY THE BEST LOOKING DESSERT ON THE TABLE BUT GOOD FOR AFTER DINNER, SNACKING AND GREAT WITH A COFFEE OR TEA. USUALLY MADE FOR THE HOUSE BUT ALSO CAN BE A GREAT TREAT TO BRING TO DINNER . THE PURSUIT OF THE PERFECT PERSON IS NOT RECOMMENDED TO EAT.

THE MEASUREMENTS NEED TO BE ADJUSTED FOR THE PAN SIZE BUT I’M NOT FUSSY AND QUICK AND EASY ALSO MEANS IT’S BAKED IN THE VORTEX OVEN, QUICK TO HEAT UP INSTEAD OF THE LARGER OVENS.

175 GRAMS OF ALL PURPOSE FLOUR

1 1/2 TEASPOONS BAKING POWDER

GINGER PASTE TO TASTE (OMIT OR SUBSTITUTE)

1/4 TEASPOON SALT

1 1/4 STICK BUTTER

175 GRAMS SUGAR

3 EGGS

VANILLA EXTRACT TO TASTE

CREAM THE BUTTER AND SUGAR IN THE FOOD PROCESSOR TILL FLUFFY ADD THE DRY INGREDIENTS, MIX AND THEN THE EGGS PULSED IN ONE BY ONE. ADD THE GINGER PASTE TO TASTE SAME WITH THE VANILLA.

PREP A CAKE PAN, I USED AN 8X8 PAN, PARCHMENT ON THE BOTTOM AND SPRAYED.

BAKE AT 340 DEGREES, THE VORTEX OVEN CAN BE FINICKY , RECOMMENDED TEMP FOR THE CAKE SHOULD BE AROUND 200 DEGREES FAHRENHEIT INTERNAL. TEMP AND TIME NEED SOME TWEAKING.

YOU CAN END UP WITH A LAVA CAKE CENTER .

COOL, TRIM THE TOP (THE COOKS SAMPLE) IF NECESSARY, FLIP REMOVE FROM PAN, CUT INTO BITES AND GLAZE WITH OPTIONAL GINGER PASTE ADDED TO THE GLAZE. (MILK AND 10X SUGAR)

DONE.

ON THE BENCH: REPLACEMENT CORD FOR TEAC TAPE DECK

ON THE VINTAGE TEAC TAPE DECKS THERE IS A SPECIALIZED , 2 CONDUCTOR POWER CORD NOT EASILY FOUND. SOMETIMES MISSING FROM A 2ND HAND TAPE DECK FROM AN AUCTION

SOME RESTORATIONS HAVE GONE TO THE TROUBLE OF REPLACING THE MALE SOCKET ON THE DECK WITH A MODERN 3 PRONG COMPUTER CORD STYLE RECEPTACLE , TODAY EASILY OBTAINED OR YOU PROBABLY HAVE A BOX OF THOSE CORDS FROM OVER THE YEARS. THE SOCKET WILL HAVE TO BE INSTALLED WITH A SOCKET THAT WILL FIR INTO THE ORIGINAL OPENING. SOME PERSONS WILL NOT WANT TO UPGRADE FROM ORIGINAL

I FOUND THIS QUICK REMEDY THAT ONLY REQUIRES A SLIGHT MODIFICATION OF THE ADAPTER, NOT THE DECK.

THE ADAPTER STILL DIDN’T FIT THE TEAC POWER SOCKET

GENTLY SAND OR FILE THE SIDES OF THE ADAPTER TILL IT FITS THE SOCKET , IT WON’T NEED MUCH , FOR A FINISHED LOOK POLISH THE SIDE OF THE ADAPTER ON A POLISHING WHEEL .

THIS ADAPTER MAY FIT OTHER 2 PRONG POWER VINTAGE DEVICES. I’M SATISFIED WITH THE QUALITY , BETTER THAN USING THE 2 CRIMP ON TERMINAL CONNECTORS WITH HEAT SHRINK INSULATION CONNECTED TO THE MALE PRONGS.

on the bench: the robots have arrived: SCOOBA 450

CONTINUING BLUEMAT GROUP MEMBER SERIES , Blue Anti Static Silicone Magnetic Repair Mat with Heat Insulation, Scale Ruler and Screw Position for Soldering Iron or Phone Repair Work Station

OF THE VINTAGE SERIES OF IROBOT DEVICES THE SCOOBA 450 IS THE LAST SERIES OF FLOOR WASHERS COMBO VACUUM MADE BEFORE IROBOT WENT WITH A DEDICATED TYPE FLOOR WASHER/MOP PAD STYLE. SEVERAL OTHER SCOOBA MODELS PRECEDED THE 450 AND MIMIC THE SIZE AND SHAPE OF THE ROOMBA (VACUUM SERIES) WITH THE EXCEPTION OF THE SCOOBA 200.

THE ROOMBA 450 HAS A ROTATING BRUSH, WATER JETS, AND A SQUEEGEE WET VAC. THE UNIT EMPLOYS 2 TANKS IN ONE , ONE FOR CLEANING WATER AND ONE FOR WATER THAT GETS VACUUMED UP FROM THE FLOOR, COMPARED TO THE NEWER MODELS THAT CLEAN THE FLOOR BY APPLYING CLEANING FLUID AND USING A REMOVABLE REPLACEABLE MOPPING PAD (OR DRY MOP PAD).

THE SCOOBA 450 UTILIZES THE SAME BATTERY PACK AS THE VINTAGE ROOMBA VACUUMS THE PREVIOUS MODELS OF THE SCOOBA UTILIZES NICAD CELLS THAT ARE NOT COMPATIBLE WITH THE ROOMBAS.

THOUGH IT’S PRIMARY USE ITS TO WASH THE FLOOR THE SCOOBA 450 ALSO VACUUMS UP DIRT, DUST AND SMALL DEBRIS WHILE IT WASHES THE FLOOR.
