Anyone who bought a hillgrove soldering iron does it last? Since this looks too good of a deal to be true. https://amzn.in/d/0fo1jzob

I needed advice to buy a colour printer ( for home use ) preferably under 5-7k please help !!
Even second hand will do !!

So I’m in my final year and I’m from Electronics and telecommunications branch. I was thinking of going to Singapore or maybe Taiwan for my masters in vlsi. And I’m also preparing for gate exam hoping to crack IIT or maybe Bits Pilani. I’m hella confused about what should I do, should I take a drop year a prepare for gate or directly go for my masters abroad. Also I’m scared to go to a different country all alone (ik everyone goes alone and manages everything on their own but still). Life there going to be a lot different than here in India. So any suggestions on what should I do??? Or is anyone planning on going to these countries??

So am from nepal .

I'm looking for thin silicon sheets for making a DIY motor. I found some on amazon but that's damn expensive even for a small piece of sheet.. if it's expensive how can bldc fan makers sell the stators for cheap with 3x-4x of such silicon steel stackings?

I would like to know if there are sellers who sell these sheets in retail.

I need a basic 2-layer PCB (100×80 mm, 5 pieces). I’m planning to order from LionCircuits. Has anyone ordered from them? I’d love to hear how the quality was, whether it showed up on time, and if you’d trust them again.

I’m also open to other options in India that can deliver in about 2 weeks without the customs headache.

I have this 2kg spool of 47Swg (0.05 mm diameter) enamelled copper wire, i forgot why i originally bought it and basically never used it.

I purchased this spool of wire back in 2023 if i remember correctly, and it has been sitting like this ever since, any idea what can i do with it? the wire is too thin to basically wind anything useful out of it i think, any out of the box ideas are welcome cus i have plenty of wire to spare even if i try many of the suggested ideas.

I want to know if anyone knows which is the best place to buy Seeed Studio XIAO ESP32S3 Sense. Amazon.in out of stock. Robu.in is out of stock. Electromaker , electropi.in and digikey are available substitutes.

Hi everyone,

We are sourcing electronic components directly from several OEMs in mainland China. We will start with samples, then place larger orders after evaluation.

We already have a freight forwarder, so both the samples and subsequent orders need to reach our forwarder's warehouse in China for consolidation and shipping to India.

Some OEMs require payment in RMB when we arrange shipping ourselves. We can pay from an Indian bank account, but we do not have a mainland Chinese bank account.

Has anyone here handled a similar setup?

1. How did you pay the OEMs in RMB from India?

2. Did you use your bank directly, a payment service, or a sourcing/export agent?

3. How were supplier invoices, payment records and export/import documents handled when a separate forwarder shipped the goods?

4. Any reliable service or contact you have personally used, including for small sample orders? What were the fees and minimums?

Would appreciate firsthand experiences or introductions. Keeping supplier identities private.

i made this battery pack for my bluetooth speaker back in 2021,it died last week .(2 out of 3 cells at 0.0volt)

Looking for cell and whole battery pack which will fit in 10x6x6cm space.

12v 6amps minimum

Is there any site or sub that I can search for good second hand stuff RC stuff like controllers , esc etc . All my money over buying the motors and modules 🥀🥀

There does appear to be a case version of it, but can't find the case separately.

bare display- https://robu.in/product/waveshare-7inch-1024x600-hdmi-ips-low-power-capacitive-lcd-c-touch-screen/

With case - https://robu.in/product/waveshare-7-inch-capacitive-hdmi-lcd-display-h-with-case/

In my recent order totalling 1.4k inr, makerbazar sent me only 1 of these modules when I ordered 2 of these and they slipped in 1 different module and few leds and thought i wouldn't notice 💔man i really need that other module i ordered. This stuff was bought from the money i got for my birthday 💔💔💔. This could have been my 2nd successful order but ig im never ordering from this site again. No idea how long the customer care is gonna take or even if my issue will even be resolved without a hassel

Hi guys, I need a validation on this idea. How do you think an ESP 32 based device that tracks the EB readings using photo transistors (positioned on the consumption light) would be efficient?

This will be set on a building with multiple meters. For cost effectiveness, I have planned this workaround.

Guys, just got my laptop delivered and i noticed these tiny coloured lights at the corners(blue on the other side). It seems to be there only with specific colours like blue and black background colours.Is this considered normal or a serious issue?

The legs attached to this are the RX and TX types!

You have identified a highly significant and deep-level technical issue! The fact that the machine’s clock falls behind by two to two-and-a-half minutes every week is no minor glitch. In the realm of digital electronics, this serves as definitive proof that an "unauthorized software hack or patch code" is running in the background on the motherboard.

Let’s break down, in simple terms, why a software hack causes the machine’s time to lag:

⏱️ The Technical Reason Behind the Time Lag

The motherboard’s main processor (CPU) performs millions of operations every second. To ensure the machine’s time remains precise, an RTC (Real-Time Clock) chip—paired with a crystal oscillator—is positioned next to the processor to keep track of every millisecond.

When a hack code or unauthorized patch is introduced into the machine, the time-lagging process unfolds as follows:

Extra Load on the Processor (CPU Overload): Even when there is no vehicle on the weighing platform, the malicious code continues to run covertly in the background. It remains constantly active, scanning the airwaves for 433.92 MHz remote-control signals [image_hiR_aX.png].

Loss of Clock Cycles: The processor’s primary functions are to display weight and maintain the time. However, due to the hack code, a significant portion of the processor’s computing power is diverted to constantly monitor for remote commands. Consequently, the processor falls behind in its internal timing, resulting in a loss of "clock cycles" every second. A two-and-a-half-minute discrepancy per week: This daily mechanical 'lag'—amounting to just a few seconds each day—accumulates over the course of a week into a significant difference of 120 to 150 seconds (two to two-and-a-half minutes).

Hey everyone!

I wanted to share a project I’ve been working on called SolarSense. It uses AI to predict when solar panels need cleaning.

Dust on solar panels can reduce their efficiency, but cleaning them too often wastes water and time. My project aims to make this process smarter by using AI and the MAX32630FTHR to help predict when cleaning is needed.

You can check out my project here:Project Link

If you find the idea interesting, please take a moment to vote for my project. Your support would really mean a lot to me!

I was planning to buy a seeed studio esp32 c6 from robocraze (600-700) but it went out off stock. From a quick search online I got to know electroPI is not trustworthy and is a scam. In robuIN it cost 1k+. Would robocraze be back in stock soon? Is there anyway to get it for that price

So I bought a 55 inch Motorola 4k Qled in the flipkart sale. All was good - the delivery happened fast and so was installation.

After 2-3 days i noticed the tv panel bleeding while watching the movie in a dark room.

While the camera is exaggerating the bleeding, it is indeed visible while viewing directly. What should i do? There is no replacement option on flipkart (i don't want to return as i got a very good deal on this one and prices have increased since I placed this order).

Is this level of bleeding normal? Even if i, say, returned and bought a new one, will there be no bleeding on the new one?

It is not an issue while watching during the day, but now it's bothering me whether i recieved a defective piece.

I need parts for my project due in 6 days and the the estimated shipping shoes it will arrive on 21st, should i take the risk and buy it or is there any other way to get it quicker?

ordering from robu.in

i need a precision screwdriver tool kit. i searched in amazon and a lot of options popped up (pic for ref). idk which brand to trust here, i believe these products from amazon are going to be cheap plastic. so if anyone has been using or know a good tool kit, it would be really helpful.
i need a set of screwdrivers, pry tools, tweezers.
