Re: Interesting assembly method...

Its lawful for you to fix electronics but perhaps not to import Apple compatible Digitizers and try to repair Apple phones yourself. Apple will serve you with a cease and desist letter for not being authorized and not using their branded parts and your screens may be confiscated by customs as counte...

Re: Energy problem solved!

If you are referring to the skin effect, I think that is negligible at 60/120 hz.

"There is probably a way to reset the Phone, and wipe the password using a certain keypad configuration that you punch in." Possibly so but without "right to repair" laws, they rarely tell us. https://www.vice.com/en_us/article/43k55w/the-most-important-right-to-repair-hearing-yet-is-on-monday I thi...

Re: Any knife makers out there?

you want a Tool and Die making Machine shop, A map search shows a few in MD. Sounds like a machine shop job but one that can cut tool steel. its going to cost several hundred, maybe less if you have an existing die they can modify with a custom sharpening. Check with these guys, maybe something cros...

Re: Crappy Headphone wires.......

Cheap assembly of audio cables or just cheap wire I have seen many many times. Unless these headphones are special to you, I suggest you change to something wireless this Christmas. As for replacement, look for 3 conductor, 28 gauge with shield though the original may have been thinner, you can upgr...

Re: laser level offset measurement

Have you picked a photo diode (PIR), can you post the part number. I am interested in output characteristics and the package it is in. you probably want to be picky about the lens and the direction the light needs to come in. Many have omnidirectional bubble like plastic lens and others are flat. Go...

Re: laser level offset measurement

Sounds a bit like a total station. so when the Photodiode is illuminated by the red laser (you may need a red filter to reduce ambient glare) the diode generates some current. If you connect that to a digital IC (probably with parallel resistor to ground) with the right VIL and VIH levels, you may b...

Re: Self entertaining, entertainment system!

with data turned off, it disables WiFi but not necessarily Cellular pings, you would need to go to airplane mode for that.

Re: Technology Backfire?

3rd party solutions provider was never really NASAs thing anyway. Even the bulk of launching other peoples satellites is going to new private companies. NASA is great at creating new technologies and spinning them off to private companies but we rarely hear of all the failures they crossed off the l...

Re: Technology Backfire?

Can't beat the market share of Photosynthesis. Collect Energy, make fruit, release when eaten. Even longer collection times and shorter usage, must have been NASA's benchmark :) I haven't seen much in the way of efficiency gains in PV in the last 5 years since the venture Capital hype died down. Too...

Tell your politicians to support the IEEE smart grid regardless of their views on global warming. One does not need global warming to see the logic in having an efficient and fair electrical grid or the jobs it can create. https://smartgrid.ieee.org/domains To be fair, in the generation market, The ...

The EPA was gutted when they moved to Kansas. Another hardball tactic from the admin to science actual science. They stay on so they can move out of the way when a chicken crosses the road. I read in a recent survey 60% of new car owners arwe turning off those warnings because they feel nannied. PV ...

Re: Technology Backfire?

A Li-Ion jump start battery with 12V cigar lighter interface is probably your easiest solution if it reoccurs. Though it sounds like the software update may be just what you needed. TSB is not that old (less than 5 months), I guess they didn't have it last time you complained.

Re: Is Nuts and Volts dead ?

Good point, even the replicator never makes paper or plastic objects its possible N&V could go all electronic someday, it would change the landscape of deadlines and cost for the publisher. A big adjustment but in this new world, may be inevitable. They can put that money into marketing and content ...

Re: I can't think today.. help !

you can also use a uController with integrated ADC and at least 3 IO lines. Likely much more accurate than an all analog thing. Try a USB based dev kit to keep the costs low, Microchip, TI, ST Micro, adafruit, sparkfun, arduino, R-Pi take your pick. Some research to select the best fit but there are...
