It's breadboard compatible so it can be plugged into a breadboard for quick prototyping, and it has VCC & GND power pins available on both sides of PCB. Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied from a single 9V battery.Īrduino Prototype is a spectacular development board fully compatible with Arduino Pro. 8-DIP machined IC socket allows to swap OPA2134 with many other dual opamp chips such as OPA2132, OPA2227, OPA2228, dual OPA132, OPA627, etc. Unlike other ESR Meters that only measure ESR value this one measures capacitor's ESR value as well as its capacitance all at the same time.Īudiophile headphone amplifier kit includes high quality audio grade components such as Burr Brown OPA2134 opamp, ALPS volume control potentiometer, Ti TLE2426 rail splitter, Ultra-Low ESR 220uF/25V Panasonic FM filtering capacitors, High quality WIMA input and decoupling capacitors and Vishay Dale resistors. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. It also analyzes transistor's characteristics such as voltage and gain. Check with your mobile operator to see which band/frequency they use.ESR Meter / Capacitance / Inductance / Transistor Tester KitĮSR Meter kit is an amazing multimeter that measures ESR values, capacitance (100pF - 20,000uF), inductance, resistance (0.1 Ohm - 20 MOhm), tests many different types of transistors such as NPN, PNP, FETs, MOSFETs, Thyristors, SCRs, Triacs and many types of diodes. Near the end of the video, Mike Haney mentions that this signal grabber is designed to nab the 1900MHz band, so it's probably most effective with providers that use this frequency.

Aim the open end of the can toward the closest compatible cell tower.

Plug the pigtail connector into the external antenna jack on the phone.

Under this should be a port for an external antenna.

Remove the rubber cover from the rear of phone, likely under the battery cover.

Attach the pigtail connector to the antenna connector.

The copper wire should be on the inside of the can.

Attach the antenna holder to the hole you cut in the can, securing in place with a nut.

Insert a short length of copper wire into the receptacle of the antenna holder and solder in place.

Cut a hole approximately 3.8 inches (97 millimeters) up from the closed end of the cylinder.Copper tape is a suitable alternative to solder too. Solder the two cans together to form a long cylinder.Remove the bottom from one of the cans using a can opener.Get other materials needed, like a can opener, solder, a soldering iron, antenna connector, and a "pigtail" connector.Get two empty metal coffee cans approximately 13 ounces (384 milliliters) in size.Newer smartphones may not have this port. Your phone must have an external antenna port for this to work. The people at PopSci discovered an interesting signal booster solution that uses a metal coffee can.
