Standalone WiFi booster?

 Hey guys, I was wondering if anyone knew of a project out there for boosting a WiFi signal.  I don't mean a parabola on the antenna of the router, I mean something that sits in another room, receives the signal, then boosts it and sends it out again.  Not sure how feasible this is, but I figured it was worth asking.  Also, I'm up for a bit of a soldering challenge :)

homemade signal booster? Answered

I was trying to figure out how to boast my signal coverage in my area, and a got an idea: to use a UHF amplifier, to pick up the towers signal and rebroadcast it. of coarse since things like WiFi, Bluetooth, and cellular 2G/3G/4G networks use two way radio, the signal can go back to the reviving end of the UHF amp, and get broadcasting to hit whatever tower. my phone should better recognize the tower, as if i just magically made a tower 2 feet away. however this might also amplify stay noise. if this idea doesn't work, why not? i think i am going to need at least a 20dB increase in power, but as of now i  need to do more research. but if i can buy a product that does a similar thing for less than $40, i would. http://en.wikipedia.org/wiki/Dead_zone_(cell_phone)#Dead_zones  http://en.wikipedia.org/wiki/Repeater http://en.wikipedia.org/wiki/Wireless_spectrum (cellphones use UHF spectrum) http://en.wikipedia.org/wiki/Signal_booster

Hydrogen Boosters for ICE's.

bike booster kit

There is a project here on how to build a "BIKE BOOSTER KIT". The kit is made up of multiple 3d printed parts, including the battery pack, charger, test equipment, and a choice of small or large rc notor. The built kit is designed to mount above the front tire either bike or trike. Although I do not know what kind of bracket is included for mounting. It can be configured to fit in a bike frame in any number of positions as long as the roller can touch the front tire. I plan to mount this on a trike, There are only two possible locations, on the handlebar stem, or the fork center hole for the fender after fender has been removed. I need mounting instructions, user manual, premium hardware kit, any special mounting brackets, and sources as to where I can buy a fully assembled kit charged and ready for mounting. I am concerned that the unit is not long enough to reach the tire from the stem. I might need some sort of extender block to make it longer. Complete advice please. reeltoreelguy@gmail.com.  photo included.

Garlic as health booster

From Unlocking the Benefits of Garlic in the New York Times:The power to boost hydrogen sulfide production may help explain why a garlic-rich diet appears to protect against various cancers, including breast, prostate and colon cancer, say the study authors. Higher hydrogen sulfide might also protect the heart, according to other experts. Although garlic has not consistently been shown to lower cholesterol levels, researchers at Albert Einstein College of Medicine earlier this year found that injecting hydrogen sulfide into mice almost completely prevented the damage to heart muscle caused by a heart attack."People have known garlic was important and has health benefits for centuries," said Dr. David W. Kraus, associate professor of environmental science and biology at the University of Alabama. "Even the Greeks would feed garlic to their athletes before they competed in the Olympic games."Now, the downside. The concentration of garlic extract used in the latest study was equivalent to an adult eating about two medium-sized cloves per day. In such countries as Italy, Korea and China, where a garlic-rich diet seems to be protective against disease, per capita consumption is as high as eight to 12 cloves per day.I read this and immediately thought, "1-2 medium cloves per day! Christy and I probably eat that much in a single serving!"Try upping your garlic with these awesome recipes:Roasted TomatoesRoasted Eggplant with GarlicRoasted Sweet PotatoesGarlic Mashed Potatoesand here are some more recipes with lots of garlic.

FM radio antennas

Are there any ideas out there for building an FM antenna booster that can be used with the usual whip antenna that comes built into most radios these days. Most of the radios are made in such a way that it is difficult to get at the internal wiring, so the booster would have to be an external unit.

Question by clarei    |  last reply


I bought one of the Harbor Freight 4 camera video surveillance systems to keep an eye on my driveway and yard.

Two problems arose. 1. Cable distance. "Tech support" says the 'cables' can't be more than the 60' that comes with the system because of loss of signal...( obviously never heard of Instructables.com)....The wires in question are very thin <1/8" with RCA and power connector on one end, BNC and power connector on the receiver end. Can I adapt the RCA camera up to exterior coax and run a larger 12V power cord alongside the coax, then convert the video signal back down to the BNC connector and achieve a 'boostable' signal? 2. I have solar panels and 12 volt batteries throughout the property, sheds and garage. Would I be able to just power the camera locally instead of running a power cord from the receiver power supply to the camera?     And.. what's a BALUN? Thanks

High Current voltage booster? Answered

So I have been doing a lot of math for a rail gun, and I finally found out what statistics I need for the capacitor to get the energy needed. But I may have ran into a problem. The voltage for the system is rather low, but the current is high, so I need a capacitor with something like 60-ish Farads, and 20 V, and of course the ones I find are outrageously expensive. ($2,400!!!) But I was able to find ones with 70 F but only 2.1 V, but since I need 20 volts I was thinking that I could use a voltage booster, but I am not sure if that would work, or if I can find/make a Voltage booster that can withstand that kind of current (would be something like 67.5 KA) the other option is find ones with higher Capacitance, which I did, but they are still a bit on the expensive side ($70, and since i need to it comes up to be $140 or so (not as much but still)) So what I wanted to know is whether it would be less expensive to try to find/make a voltage booster, or just buy the $70 capacitors? I suppose I should also be asking is it even possible to get a voltage booster that can that that many amps, and how easy would it be to make? Oh almost forgot, another question (which would skip having to solve the others) is: Is there a way I can increase the voltage that a capacitor can take, or increase the voltage in a capacitor bank, or some variation of those? Because if there is, that makes everything easier, but I couldn't find anything on doing that so yeah...

Laptop Fan voltage booster

Hi, my laptop is overheating because the fan isnt fast enough. My idea is to build a small voltage booster to increase the fan voltage a small bit. It will be overvolting the 5v fan but i dont mind. For example, when idleing, fan voltage is at 3.5v and at full load its at 5v and i would like it to be 1-2v higher at both points WHILE still maintaining the variable control (spinning faster and slower as needed) Problem is, im pretty good at soldering but i dont know how to make one.

how do i amplify the radiofrequency of my 40mhz remote control so it will operate my receiver from a further distance? Answered

as some of you may know now, i am building an r/c tank, it operates on a frequency of 40mhz. now i have a problem, the old remote controller i had for it which i modified (by accident), has been thrown away after it stopped working (thanks to my un-understanding mother) the problem with this is though that i when i changed it around (i swaped some parts to make it work with aa's instead of button cells) it worked at 100m, the remote i have now though wont operate the receiver at any distance above 40 meters, so i want to know, where can i get a rf booster that will work for my remote control, sort of a thing that can boost the signal as it goes though the antena, or something, ive seen something like it in jaycars catalogue, but it only works on frequencies between 50mhz-1ghz, and it extends the radio coverage by 100m. since its only a toy remote i dont think it can be alterd, plus this one isnt the same as the chip transmitter i used to own, this one is a crystal remote controller.

Anyone know how to build a Cell Phone Repeater or Booster for a tower?

I'd like an economical way (if that's possible) to build a cell phone repeater or booster that can work for multiple cell phones, and be mounted on top of a tree or some other tower or pole. (Boosting signals here is legal). The reason I'd like to do this is because we use a cabin that's located deep in the forest and currently cell phone signals are spotty. (Move down the road 100 feet or stand on a stump and it works, but not where you really need it to). My concern is for safety as many of my family members use this area, and if there were ever a problem, I'd like to know that we could get a call out for help. I've done quite a bit of searching on this already, and have found several methods to improve the cell phone antenna, or the coffee can method, but what I'd really like is something that can work for ALL of our cell phones (that are with different cell carriers), and therefore (as I understand it), can be on different frequencies. The only thing I could find were devices that were out of the box ready and at a hefty price. Does anyone have any advice? or can point me in the right direction in order to build something like this that will work? Thanks, canucksgirl Edit: Let me clarify that the intended purpose isn't to be able to contact 'emergency services' from camp. We're a few hours from the nearest town and it isn't conducive to 'sit and wait' for help to arrive. Our group has been extremely safe, competent and self sufficient in that area for more than 30 years. Without getting too personal, we have an "in town" family member with a serious illness. If there were ever a reason, we'd like to be able to reach family at the camp to let them know that they needed to return home.

I need help connecting 2 solar panels in paralel

Hi,I'm new to Electronics but I love solar panels and hiking.S, I bought 2 of these:https://www.tomtop.com/p-l1613.htmland one of this:https://www.ebay.com/itm/Dual-USB-Solar-Boost-DC-D...and I connected them. I cut 2 USB Cables, connected + with + and - with - from each Cable and connected it to the DC-DC booster. The amperage is not doubled and the output Volts are lower than 5V which should be the constant output of the booster. The panels were solar oriented and the output was only 0.02 A with Bright enough sun from those 2 solar panels. The panels separately work fine, it is only when I connect them to the booster that they act weird.Is the problem in booster or is it me doing something wrong?Thank you!

Connecting the ground to my enclosure?

I'm building gmoon's Valvelitzer inside a utility box. I've just realized that the entire enclosure is going to be grounded, meaning it's going to be directly connected to the negative pole of the power supply, which seems to run at 14V 2.2A (It'll be regulated at 12v before it gets to the tube). Is this dangerous? If it isn't, should I just solder all the ground points to the enclosure? If I run the power along the enclosure, is that going to cause some extra capacitance? Is that bad?

most simple and smallest way to charge a 6kV capacitor?

Hi again, I need some ideas on what type of DC-DC or DC-AC converter I can use to convert 9V into 6kV. the 9V will be a standard 9V battery. The output current doesn't need to be high. It's for charging a 6kV capacitor, and this May take a few seconds. It doesn't need to be charged in a few milliseconds. My own suggestions are these: - DC-DC booster (switching a coil to get high voltage spikes) but these only generate 200V max I think - DC-AC inverter like those small CCFL inverter circuits - Flyback - not compact enough - booster or inverter connected to a marx generator - but also not compact enough - ... any other ideas? It also doesn't matter if the output is AC or DC, I'll just add a HV diode to rectify it. Although, that also takes some space and it has to be Really compact. I know that converting 9V into 6kV might not sound like a simple thing, at least if I want to do it in one stage, but I've seen videos where people convert the voltage from a 1.5V battery into 4inch sparks. (that was with a marx generator too though).
