Question seen at Facebook electronics discussion group: I have 12 V ,1A DC Adapter, I want to convert it output up to 3 volts DC Power Supply for a “Gas Geyser Ignition” Circuit. What will be do for it? Easier solution is to get a new transformer / power supply with 3V output. There are →
One way to test electrolytic capacitors is to measure their capacitance. It does not tell the whole story of capacitor condition. Another usually more useful way to measure electrolytic capacitor condition is to use an ESR meter. Here is ESR meter I built years ago based on instructions from http://ludens.cl/Electron/esr/esr.html but I built the transformer →
Thermal paste has vital importance, even if many people do not realize how useful it is. On the web, you can find many alternatives to the thermal paste. This article has test comments on several alternatives, which many of are edible snacks. The article mentions: Cocoa and hazelnut spreads, butter, Ketchup, mustard, American cheese, Yellow →
Electronics prototyping is an important part of electronics device development. Prototyping means to build and test an early version of) an electronic circuit. Prototyping your product is all about learning. Each time you create a prototype version you will, or should, learn something new. Start with the most simple, low cost way to prototype your →
I have made earlier a post on electrical car charging cables and charging stations technology. This s a continuation posting related to it. This posting links to DIY projects related to electrical vehicle charging cables. Those cables are quite expensive, so some DIY persons have tried to make their own versions. Some even claims have →
https://hackaday.com/2019/11/15/needling-your-projects-3d-printed-pcb-probing-jig-uses-accupuncture-needles/ Trying to probe a modern electronic circuit with tiny SMD components, without letting the magic smoke escape in the process, can be quite a challenge. [Giuseppe Finizia] solved this problem with a 3D printed PCB probing jigthat uses acupuncture needles. [Jonathon Oxer] from the YouTube channel SuperHouse did a very nice video on the →
I had earlier written about NanoVNA and how the device I got came without battery. The device supports rechargeable LiPo batteries, but the batteries are not included on the model I bought because of the safety of international transportation. I also liked to have the LiPo battery installed on my device. The device has battery →
I had some broked LED flashlights and I thought of using components from them. Especially the compact battery holder that takes three AAA batteries looks useful in other small projects. Those worked OK when lightly loaded. But when I started taking current for a small motor, I could not get acceptable power out of them. →
