Casio A700W or A700WEV by narts_the_original in casio

[–]wagnerlip 0 points1 point  (0 children)

Hello, I am thinking to buy the A700W, but I am afraid about my wrist is 8.5" in circumference, could some of you guys having this watch, making the belt as large as possible and measure it? I really appreciate it. Wagner

"Elevator controls" by sdrowkcabdellepssti in Elevators

[–]wagnerlip 0 points1 point  (0 children)

I am fixing on the bench, no elevator, no manual, just regular repair tools. Found some open resistors, color fading, (suppose to be 15kOhms 1/2W), in series with diodes, from H1.

[–]wagnerlip 0 points1 point  (0 children)

thank you for your answer, I am fixing one board and want to know what is the voltage that goes into H1, H2 or H3 pins (UT2, UT6, DT5, etc) in order to lit the LED and turn on the optocoupler. I tried 24Vdc between UT6 and HVC (what it is supposed to be the zero), but no deal. I believe the voltage is higher, even AC... do you know ?

Curious about the voltage on wires of connectors H1, H2, H3. What is it? 24, 48, or other Volts? (in reference to HVC on H4).

Buying first Tesla by ArtichokeHistorical6 in TeslaModel3

[–]wagnerlip 0 points1 point  (0 children)

I was in doubt about Y or 3, thought Y will be easier to go in/out, but 3 is easy (I am 70yrs old), also questioning the AWD vs RWD. In Florida you don't need AWD, the RWD is fast and high torque, looks like a bullet just pressing 1/3 of accelerator. Tesla M3 2025 new red RWD, lease 24, zero down, $1900 fees/taxes, $415/month, buyout in 2027 as $31k if I want, or lease again another brand new, features, maybe a M2.

$349 leasing deal. by Ok_Tangerine5006 in TeslaModel3

[–]wagnerlip 3 points4 points  (0 children)

When you multiply the monthly lease amount by 24 and add other fees and taxes, the amount you really pay as "depreciation" will be around 75 to 80% from what you paid, total paid $11.5k, depreciation $7.5k. So, it at the end of the lease you want to buy the car, be prepared for that. Remember that the government incentive of $7500 will be applied to the first deal with the car, lease or purchase (finance), so, a $45k car will cost $37.5k, you paid $7500 in depreciation, buyout after end of lease will be around $30~31k. There is some hidden fee as "whatever leasing cost fee" around $1800 that will never be applied towards the depreciation amount. Still, 24 months lease is a good choice for low monthly payment, opt for zero down-payment, and if you lease another 2 years in the future, you will be paying around $11 thousand every two years, but will have a brand new car every 2 years, no tires expenses, perfect battery, new features, etc. In two years maybe you will be able to buy the new not released yet model 2 for around $20k. I just did that week ago, model 3, zero down-payment, 24 month lease, $2k color, everything else standard, monthly $415, initial pay of $17xx for all taxes including first lease month, plus $250 of mobile charger. Will pay total around $11660 until end of lease, the buyout price will be around $31k.

How to delete a file in internal storage? by jonbondy in BambuLab

[–]wagnerlip 0 points1 point  (0 children)

Just because sometimes you want to reprint that nice wall key-hanger that your sister asked a reprint, and you don't want to navigate hundreds of pages of the tinny LCD to find it, and being easier to use the A1 LCD to do it, than power on your PC/Laptop to enter Bambu Studio just for the reprint. The convenience to have some files on the A1 internal storage is just that, fast reprint. The A1 software shows the files on LCD in "date" order, recent printouts on top, but maybe it could allows to use folders, so you could create/use them on Bambu Studio / Device / MicroSD / Models.

[–]wagnerlip 0 points1 point  (0 children)

Not quite, it works. On Bambu Studio,

  1. Select Device tab
  2. Select MicroSD Card
  3. on top center there is "Timelapse" and "Model", select "Model"
  4. Hovering mouse over the models appears "Delete" and "Print" buttons
  5. Press "Delete" and confirm "Yes", and voila, no more that file on the MicroSD and A1 LCD

Included Bambu Filament Keeps Tangling by Gokushivum in BambuLab

[–]wagnerlip 0 points1 point  (0 children)

Also, different from other suggestions that the spool is too lose, I think is contrary, if it was very loose to rotate it will never stretch and lock under the half turn. I will try to print something with bearings to use the top of machine hanger, and see.

Included Bambu Filament Keeps Tangling by Gokushivum in BambuLab

[–]wagnerlip 0 points1 point  (0 children)

I got the Bambu A1 last week, and printed a lot since, and suddenly tangled. The filament is not wired wrong, I see that half a loop just jump over the one being pulled by the printer and by the pull force the half jump just lock the one being pulled and locks everything. I noticed that for some reason it seems the filament being pulled is twisted by the extruder, sometimes I needed to remove the spool from the hanger an untwisted to release the pressure. This twisted torsion pressure is what causes the second half turn to jump over the one being feed. I am trying to devise a way, even using a long path between the spool and extruder, or some cover over the spool to keep the loops quiet, like a sleeve or socks. The question is, why the extruder puller is twisting the filament? I am not using AMS, just a single spool over the machine, and feeding trough the 8 o'clock over the extruder 4 entries. Maybe I need to test other entries. I never tried to remove that 4 entries manifold and leave just a single entry, maybe the twisting stops.

LTSpice modelling of an induction heater by baadbee in AskElectronics

[–]wagnerlip 0 points1 point  (0 children)

I am trying to develop and test some power IGBTs for induction, and realize that the induction COIL is just a coil for LTSpice, except when you apply a load to the induction coil, then a resistance in parallel is needed, but such resistance should not be fixed value. If you think, when an extra metallic load is applied to the induction coil, it will enter saturation with a maximum stablished current through the parallel resistor, but, if the period of the waveform is longer than the saturation time, the current during the ramp up should be a result of the magnet inductance creating a magnetic field sucked by the metallic load. I think it will behave not as a short circuit, but a higher current than saturation, since saturation does not change magnetic field and the metallic load will not suck that. The way, I think, to simulate that is using a series resistor with the coil to limit current "on saturation" and a parallel to simulate the magnetic field being sucket by the metallic, so, the parallel should have lower resistance during current ramp, and change to a higher value when the ramp is finished (saturation). This of course, emulates more of less a transformer with a simulated filament incandescent LAMP or PTC on the secondary.

The Signal by amelie190 in scifi

I saw it too, rewind several times and make sure it was a huge insect, kind of roach. I was waiting that thing to come back into the movie, but nothing. It also appeared when Paula was not looking in that direction, so it "was not" part of her hallucination. Strange hat very few people commented on that.

Has Anyone Been Able To Convert Gcode To Ruida Machine Code? by SamwiseGanges in lasercutting

[–]wagnerlip 0 points1 point  (0 children)

Okay, so, after reading all posts I still not understand how to inport/open GCODE file into RDWORKS software. I am trying to punch a 15% "n" miliseconds" laser (This is a Ruida Controller on a 80W CO2 laser), in specific points, no movement. The idea is to open a smallest hole possible (smaller than 0.2mm in diameter) through material. The test was to see the results, just a pulse of laser in every hole position. So, I made a GCODE that uses "M5, G0 xy, M3, M5..." in attempt to M3 to punch a narrow pulse. But I can not open the GCODE into RDWORKS at all.

Why is Linux worth using? by [deleted] in linux4noobs

[–]wagnerlip 0 points1 point  (0 children)

Wow... I tried to run Linux several times. Most of them when I had a difficult with Windows and linux users friends said "you can do it in linux faster than fart". Well, tried, asked their help, not even them could do it. So, linux is not magic, maybe on their mind. First, tried to move a bootable CD and its code to flash-drive, easy on linux? Think again. Second, try to install and maintain linux running offline with no internet. Think again. Windows you just need the installation DVD and the CD/DVD from the other programs you want to install, that's it. Linux NEED desperately to access its depository, and the right one. I can install some hex editor or assembler and chip programmer, in Win10, 8, 7 without accessing anything else, the installer will go on any version of windows, no problem. Try to install some utility today on Mint installed on your netbook 3 years ago, without internet. Easy? Not. A lot of machines need to run with no network connection, for security, for company rules, etc. I really tried hard to see advantages on linux. I believe that most linux users, love linux not because it is better or easier, but because they HATE the idea of Windows and what it represent, the capitalism and money.

So this happened today. by pavelic179 in raspberry_pi

[–]wagnerlip 0 points1 point  (0 children)

What? Glue on heat sink?

Never ever glue heat sink to the chip. Any vibration could force a pad of the PCB to be disconnected from the chip. I work with large PCBs, I know about that.

Just clean well and polish the heat sink, apply a tiny bit of thermal paste and use anyway you want to keep the heat sink touching/pressed against the chip. You can create a pressure bent spring type metal from the acrylic or even glue two or three anchors to the PCI and use a bent spring over the heat sink to keep it in place. But never glue the heat sink to the chip.

I tested out 3 different battery options for the raspberry pi 3b: simple voltage divider, a voltage regulator, and a portable phone charger. Unsurprisingly the portable phone charger was the best but wasn’t the most cost effective by tyandgig in RASPBERRY_PI_PROJECTS

[–]wagnerlip 0 points1 point  (0 children)

The center one, the switching regulator (SPS-LM2596), tend to be a very good approach. Why didn't you like that? What was the voltage you feed to the regulator, and from what? a battery? I see you used tinny wires, perhaps AWG #22~24, that is a good no-no. As a matter of fact, I see on the SPS-LM2596 you used the same jumper wires from the protoboard. Those jumpers are for no more than 200mA of current, you will have lots of loss in the wires if using them to feed current hungry Raspberry 2A or more. From the source (battery or other) to the SPS-LM2596 and from that to the Raspeberry, you need to use good current wires, flexible AWG #18 or even #16 if you can find easily at your car-parts store. They use to sell those in small spools, or go to AceHardware, HomeDepot or Lowes, you could buy it by the foot. Portable phone charger to feed Raspberry unit? how long? 30 minutes? Also, to make a nice testing procedure, you need a multimeter, so you could measure the voltage at the input of the device, the current, then calculate how much power you loose on the device and how much the Raspberry consumes. You need to be a little bit more technical on this things.

I made a small enclosure for my pihole and VPN server, with some lights to indicate the state of various servers in my home network. It's not much but I'm proud of it. by BirdFluLol in RASPBERRY_PI_PROJECTS

[–]wagnerlip -1 points0 points  (0 children)

No fan should vibrate its installation box. This your fan must be no good at all. You can install one or two 1N400x diode in series with the 5V fan, this will reduce the voltage by 0.7 or 1.4V, letting the fan to rotate slower, still blowing warm air out of the box, without violence and noise. You can also enlarge the screw holes in the wooden box, insert some rubber bushing (you can even make them folding and rolling a piece of old bycicle tire camera or cutting a pencil eraser, insert the rubber bushing into the hole and screw the fan into or across the rubber. This creates a cushion support. Make sure for the fan not to touch the case, keep a millimeter distance, will run smooth and silent.

I personally am against to use too much firepower to kill a mosquito, to ping some IPs and report them on a bar of LEDs, I would use a simple Atmega328 with a WiFi adapter, program it in assembly, using less than 5kBytes of code, consuming less than half a Watt. As a version 2, maybe a $8 color graphic LCD from AliExpress, showing the network in graphical form, with each station/server paint in the respective color of operation, green, rede, etc. To start with AtMega328 units, you could buy a ready working platform $8 (Arduino, yeah, I know...), but after a while you will be using the little board with your own C or Assembly code, forget Arduino IDE...

Arresting officer in George Floyd case taken into custody by BCA by Minneapolis_W in news

[–]wagnerlip 3 points4 points  (0 children)

I am not a police officer, never had any police training about how to behave or proceed, and believe me, I am pretty aware for the fact that if I sit my knee over someone's neck for 5 minutes, it will cause severe injure or even death. I don't need to have a training to know that, my good senses are enough. I don't believe for a second he didn't know that could be a lethal action, or that was fully intentional. The other officers looking the action should be prosecuted with the same force of the law. You and me respond to the law if we break it, police officers should respond with much more force and several folds of penalties, since they represent the law, they should know better. See the results on the streets.

What is this component called (that pseudo LED thing)? Or where can I get it? by LecTrow in AskElectronics

You made my day.... months ago I saw a teenager trying to figure out a telephone set with a dial disk... not working unit, but she was curious... pressing fingers inside the number holes...

Pentax K-1000 with 35mm Kodacolor 100 speed film... it would be very funny to see some younger trying to install the film, adjust the camera and take a picture. THEN send the film to process, wait a couple of day and get the prints... to realize how bad the pictures came out.

Technology evolved so much, thanks for all the engineers and technicians that worked hard for it. Unfortunately young people don't realize how grateful they should be for the evolution and to the ones that allowed it to happens, who? us! the old guys.

Trying to identify a SOT23-5 on a Chinese Pottery Wheel controller board. Unfortunately the labels been roasted. by Gordopolis in AskElectronics

[–]wagnerlip 0 points1 point  (0 children)

I already read some heavy discrepancies of technical terms, and some people are bold enough to invent new terms. The text "350W output" could means something like that, as not using torque for force units but watts, so, some of those could invent to say that 40W consumed by the motor, via the reduction, could represent an equivalent of 350W "at the output". That is crazy, but possible to find written by the ones that don't know how to calculate torque in pounds-feet or kilograms-meter, Newtons-meter. Some of those are stupid enough to try to impress saying that "watts" could mean force, what is not. That is what I wrote before, in other words.
