content: Hi everyone.I'm not sure if this is the right section to post this but Andonstar is having a storewide sale ( 30% ) and a 7$ coupon. its a pretty good deal honestly. if anyone is interested in getting their products check their reviews first it got very good feedback from various youtubers and in discord community. i got myself an adsm201 and a 10 days delivery time ( i'll review it later ) and for someone who does laptop repairs daily , its really awesome and thank god i haven't bought an expensive microscope. cause its not worth it for me. ( that's just my opinion anyways)I usually buy Chinese stuff from aliexpress but i went with their official website cause :Paypal is accepted.After service.CheaperDelivery time is way better than Aliexpress.This is their official website if anyone is interested :https://www.andonstarmicroscope.com/COUPON code : summersale01

Digital AC Dimmer Circuit Using STM32 - Page 1

content: AC loads live with us! Because they are everywhere around us and at least home appliances are supplied with the mains power. Many types of industrial equipment are also powered with the single-phase 220V-AC. Therefore, we frequently face situations that we need to have full control (dimming) over an AC load, such as a lamp, an AC motor, a vacuum cleaner, a drill, … etc.We should know that controlling an AC load is not as simple as a DC load. We have to use a different electronic circuit and strategy. Moreover, if an AC dimmer designed digitally, it is considered a time-critical application, and the microcontroller’s code must be written carefully and efficiently. In this article, I introduced an isolated high power digital AC dimmer that consists of two parts: the mainboard and the panel. The panel board provides two push buttons and a seven-segment display that allows the user to adjust the output voltage smoothly.

content: A BLE beacon broadcasts its identity to nearby Bluetooth devices, to enable the other devices to determine their location relative to the beacon, and to perform actions based on information broadcast by the beacon.Example applications of beacons include indoor positioning system, location-based advertising and more.From the definition of its purpose as a broadcast device, a BLE beacon thus cannot be connected to, and can only send information in its Bluetooth advertisement packets.There are several BLE beacon protocols. The Ameba BLEBeacon library supports the iBeacon and AltBeacon protocols.Referencehttps://www.amebaiot.com/en/amebad-arduino-ble-beacon/;https://www.amebaiot.com/en/

content: Inrush current/Switch-ON surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Inrush current is much higher than the load’s steady-state current and that’s the source of many problems such as fuse blowing up, load failure, load’s lifetime reduction, sparks at the switch contacts … etc. I tried to address this problem with an easy, however effective solution. I have introduced two circuits for both AC and DC loads.

content: BLE connections use a server client model. The server contains the data of interest, while the client connects to the server to read the data. Commonly, a Bluetooth peripheral device acts as a server, while a Bluetooth central device acts as a client. Servers can contain many services, with each service containing a some set of data. Clients can send requests to read or write some data and can also subscribe to notifications so that the server can send data updates to a client.In this example, a basic battery service is set up on the Ameba Bluetooth stack. A mobile phone is used to connect the the Ameba peripheral device and read the battery data.Referencehttps://www.amebaiot.com/en/amebad-arduino-ble-battery/;https://www.amebaiot.com/en/

content: As we all know, the COVID-19 outbreak hit the world and changed our lifestyle. In this condition, alcohol and hand sanitizers are vital, expensive, and in some areas hard to find fluids, so, they must be used properly and efficiently. In the second version of the hand sanitizer dispenser device, I have addressed the previous design problems and introduces a device with no sensitivity to the ambient light and flow control capability of the alcohol/sanitizer. Therefore just enough amount of liquid will be poured on each request. The design uses a cheap ATTiny13 microcontroller.Features1) High stability and no sensitivity to the ambient light2) Laser-cut acrylic (plexiglass) enclosure3) Cost-effective4) Flow control capability of the hand-sanitizer/alcohol (efficiency)5) Through-hole components (easy to solder)6) Single-layer PCB board (easy to fabricate)7) Single and cheap ATTiny13 microcontrollerLow standby current consumption

Here's one of them that shows how to measure a resistance or capacitance beyond the range of your multimeter. It also shows how to calculate total resistance or capacitance of two resistors or capacitors in series and parallel. I'm sure most people on this forum will already know how to calculate these, but maybe some haven't realized how this can be used to measure values higher than the range of the meter.Also, currently on my 2nd channel is an excerpt video showing the ElectroDroid app which has many connector pin-outs, electronic calculators, component codes, etc. This can be really useful in bringing out your inner MacGyver.I'll be uploading more videos soon covering designing simple power supplies, applying Ohm's Law, my CPU design running on an FPGA, simple BJT transistor switching circuits, old electronics/computer magazines, magnetic core memory, and more.

content: Common misconception that a fuse should have blown if there was so much current flowing that the circuit caught on fire.Fuses protect from massive over-currents, like short circuits, they don't know where all the energy is going.Is 10W going into a 10W heatsinked IC or into one tiny spot on the PCB.The typical current draw of a circuit is usually plenty large enough to start a fire if focused in one spot instead of going where it's supposed to go,Example 10 ohm 1/4W resistor.5V into 10R = 0.5A5V * 0.5A = 2.5W2.5W into a 0.25W resistor and you're going to get fire, but 0.5A is not much current at all when considering fuse values.It's made worse when the thing that catches on fire is made of something oil filled or flammable.

content: LM317 is one of the most popular adjustable regulator chips. The output voltage of the regulator can be adjusted from 1.25V to 35V. However, the chip can deliver currents up to 1.5A which is not enough for some power applications. In this article/video, I will discuss two methods of LM317 current boosting, using power PNP and NPN pass transistors.

automatic drone charging - how would you design it? - Page 1
Forum section: electronics / general

author: NiHaoMike
author_rank: Super Contributor
timestamp: January 12, 2020, 03:13:40 am
content: Looking at the PCB mounted on the drone, it appears to be a bridge rectifier and buck converter. I clearly see the chain of thought that went into the design: polarity could be either way - use a bridge rectifier to solve that, bridge rectifier drops too much voltage - use a higher voltage and regulate it down. Not bad for an artist with limited EE experience (also keeping in mind it's a proof of concept), but how would an experienced EE design it?My take is that since weight is basically everything on a drone, the part that mounts on it could be simplified to just a MOSFET + few passives for reverse polarity protection. The base (without the strict weight requirement) would alternate the polarity to the contact grid while monitoring for current draw.

author: I wanted a rude username
author_rank: Frequent Contributor
timestamp: January 12, 2020, 11:03:42 pm
content: Yeah, weight minimisation is paramount. So no induction coil for example.The drone and pad could negotiate over the pogo pins before the pad applies charging current. Then the drone would always receive the right voltage with the right polarity, minimising weight. If this functionality were integrated into the microcontroller that the drone already has, it would cost a few passives and the pogo pins.Wu's physical solution is pretty good.
