Build a USB Powered AA NiMH and NiCd Battery Charger I’m always complaining about all the chargers and wall warts I need to carry with me when going on a trip. This project, which can charge a pair of AA Nickel Metal Hydride (NiMH) or Nickel Cadmium (NiCd) cells using a laptop’s USB port for power, arose to address part of that problem. Rotary Encoder for ATS Transceivers Electronics DIY This equipment is dedicated for an easier control of the popular mini transceiver AT Sprint known by ham radio operators as ATS (series ATS 2, ATS 3, A, B, B.1 compatible). Originally the ATS has just four push buttons on the top cover and in combination with the paddle it is possible to send all commands to ATS including the tuning, scanning etc. The uTracer, a miniature Tube Curve Tracer Tester. 17th of July 2016, Bo Johansson made a very nice uTracer with the thumbwheel switch from a scrapped AVO MKIII! Dear Roland, It was a while ago I bought the uTracer kit from you! Microcontroller Voltmeter Ammeter with LCD Fine voltage circuit regulation potentiometer. To reduce ADC conversion errors like un linearity, gain factor etc. measuring range is divided into two sub ranges 0 10V and 10 30V (switch threshold can be between 7 13V depend on sourcing current and elements tolerance). The Internet of Things with ESP32 Created by Espressif Systems, ESP32 is a low cost, low power system on a chip (SoC) series with Wi Fi & dual mode Bluetooth capabilities! The ESP32 family includes the chips ESP32 D0WDQ6 (and ESP32 D0WD), ESP32 D2WD, ESP32 S0WD, and the system in package (SiP) ESP32 PICO D4.At its heart, there's a dual core or single core Tensilica Xtensa LX6 microprocessor with a clock rate of up to 240 MHz.

Pages in English and French are denoted by the addition of (E F) at the end of their links.. Main Circuit Index The uTracer, a miniature Tube Curve Tracer Tester. This page is the preliminary manual for the GUI V3.11. Many features of the GUI 3p11 have already been documented, however the selection between the uTracer3 and uTracer3 has not been added. How to rejuvenate rechargeable NiCd batteries « Flounderings This post is about a method to restore (rejuvenate) NiCd (NiCad) battery packs that are failing to charge. I have 2 sets of cordless tools (drill, circular saw, reciprocating saw and more) that use rechargeable NiCd battery packs. How to Replace a Ceiling Fan Motor Capacitor Given the permanent wiring situation, the only way to replace the ceiling fan motor capacitor is to cut the capacitor wires. Use a pair of wire cutters to cut the capacitor wires off close to the capacitor such that you have sufficiently long wire leads to wire in the new motor capacitor..
