So I'm fully grasp in the tism rn so forgive the question. I'm wondering about using an old HP laptop screen and lid for a project that could benefit from a screen. is there way to determine what the pins are on the back of a screen. I do not have a part number or anything and if I was to guess imma have to figure out what the screen is and check some sort of technical drawing. But is there a way to determine what is what without that so I could say convert it to HDMI? Thank you in advance.

What do you guys think

i started with a 17inch crt display but it was way to small so i changed to 24 inch display

I am also waiting for an artist friend of mine to paint the machine

What should i do to improve

Hi everyone!

I've developed Avenler, a free, browser-based electrical design tool for electrical installations.

Main features:

• DXF/PDF import and export
• Automatic cable and circuit assignment
• Bill of materials (BOM) generation
• Quotation and cost estimation
• Project sharing and collaboration
• No installation required

The software is free to use. Registration is required for the design tool.

I'd love to hear feedback from electricians, electrical engineers, and designers.

What features would you find most useful? What would you improve or add?

Thanks for checking it out!

This my project :]

Current work in progress for an iMac G4 mod, starting with converting a busted display into an external monitor using a replacement LP170WQ1 panel used in the LG Gram 17 laptop. This LCD panel has a resolution of 2560x1600 (WQXGA) at 60 Hz and is a perfect size match for the original 17" panel. I bought it from Aliexpress as a bundle with a driver board (supporting USB-C and mini-HDMI display input, and microUSB for power in the case of mini-HDMI): https://www.aliexpress.com/item/1005009505924522.html depending on deals it costs around $100-150 USD.

As you can see, the original iMac was already not working and in terrible condition, so nothing of value was lost except for cutting the cables on either end of the neck. All exterior parts were given a good scrub in soapy water. I didn't want to open the neck to run through a USB-C cable for example because I didn't have a spare just in case, knowing the difficulty of putting the neck back together again. So, I opted for an external, less elegant solution of running a thin USB-C ribbon cable from inside the display housing though a tiny gap between the back-plate and the (new) bezel, where it is connected to a female-female (8K 240W 'certified') adapter into which a USB-C cable+computer can be plugged. (I know such USB-C adapters are not the best idea for many reasons, but I couldn't find a longer thin ribbon cable that was of a practical length to connect the driver board directly to a computer.) Likewise for the small controller board, whose flex ribbon cable can slot through the same gap. I will try to 3d print a case to house these two parts rather than let them hang outside like currently shown.

Anyway this arrangement is working with a Surface Pro running Windows and also an M1 iMac (in the background, which coincidentally also has a busted screen, the infamous horizontal lines problem). As the original display bezel was also completely destroyed, I measured the bezel dimensions and ordered a new one made of 2mm clear acrylic from a laser-cutting shop (the protective paper sheet is still on in the photos). This frame is kapton-taped on top of the LCD panel, which is then stuck to the metal bracket in the display housing with mounting tape (since the LCD panel is so thin and light, the metal bracket can be kept for weight to maintain the correct neck tension). I will also cut a smaller white frame out of a vinyl sheet to glue on top at a later date, which would ideally make the bezel look like the original again. I will share a vector file of the bezel dimensions to scale in a future update post.

Thanks for viewing, and any suggestions are welcome!

I’m a first-year Mechanical Engineering student working on a group project about a Smart Parking System. We’re trying to find a technical solution to the problem of drivers wasting time and fuel searching for available parking spaces, especially in crowded areas.

Our initial idea is to use ultrasonic sensors to detect whether a parking space is occupied, an Arduino or other microcontroller to process the data, and an LED display to guide drivers to available spaces. We’re also considering adding a mobile app to show parking availability.

I’d love to hear your thoughts on a few questions:

1. Is this approach practical for a small-scale parking lot?
2. Are there any better or more affordable alternatives to ultrasonic sensors?
3. What challenges might we face when implementing this system in real-world conditions?
4. How can we make the system more energy-efficient, reliable, and cost-effective?

Any suggestions, personal experiences, or examples of existing smart parking solutions would be really helpful for our project.

I was going through an old box of stuff and came across an original Flip Video Camera. Other than selling or donating it, does anybody have an idea on any projects I could post do with it? Not against opening it and scavenging it for pieces for a project.

Hi everyone!

I have an old Acer Iconia B1 tablet that I’ve already taken apart (photos attached).

I’d like to use its components to build something cool and useful!

Please share your ideas for this tablet.

I have a few questions:

What interesting DIY devices can be built using these parts?

Can the original motherboard be used for a DIY project?

What additional components, tools, and software would I need?

I’d prefer a relatively low-cost option and am willing to learn new things along the way.

I’d especially appreciate advice from anyone who has experience repurposing old tablets.

What would you build with these parts?

I’d be grateful for any ideas or tips!
