A Wristband To Remove Static Electricity


ARCTIC EAGLE Anti Static Wrist Strap, 11" Anti Static Wristband Grounding Bracelet with Alligator Clip and Extendable Long Cable

This wristband is 100% optional, I never used one, but the goal of this tool is to remove static electricity for your hands. Usually what I suggest is to touch something metallic before trying to disassemble a computer or wear clothes that does not conduct static electricity.

A Magnetize/Demagnetize Tool

Wiha 40010 Magnetizer & Demagnetizer Shatter Proof Box

If you bought the first tool kit, do not buy this, as it is included in the kit. This tool is also 100% optional, I used this tool a few time to make a non-magnetic screwdriver magnetic it is highly useful when you are trying to hold screws on your screwdriver in hard to reach spot.

Small Cutters

These small cutters will be useful to cut tie-raps or Velcros when you are doing cable management.

Velcros For Cable Management

These Velcro will be useful to clean up the inside of a tower PC. It will be used to tie everything together nicely.

However, if you do not have enough money to buy all of this, do not worry, there is always someone Who can donate you an old computer or tools that have been forgotten in a closet somewhere. Facebook marketplace can also be a great to find such tools & equipment.

Additionally, you need two different tool kit unless you can find one that has everything in it. You need one tool kit for small electronics (good to dissemble phones, and laptops). Not only that, but you need an old laptop to gain experience on how to remove each component and how to reassemble it so that it function flawlessly.And finally you need an old computer to see how it is made inside and to be able to identify each electronic parts.

How To Search The Web

Google Search

To search on Google effectively, follow these tips:

  1. Use quotation marks: Enclose exact phrases in quotation marks to search for them verbatim. This ensures you get results with the exact sequence of words, rather than individual words.
  2. Use the minus sign (-): Exclude specific words or phrases by prefixing them with a minus sign. For example, searching for “chocolate chip cookies -gluten” will return results without gluten-containing recipes.
  3. Use OR: Separate multiple search terms with OR (in uppercase) to search for either term. For example, “Best 1TB HDD” OR “Best 1TB SSD” will return results for both hard disk drives and solid-state drives.
  4. Use site:: Search within a specific website by adding “site:” followed by the website’s URL. For example, “site:pcmag.com Google Photos tips” will return results from PCMag’s website.
  5. Use filetype:: Search for specific file types (e.g., PDF, DOC, JPG) by adding “filetype:” followed by the file extension. For example, “filetype:pdf tutorial” will return PDF tutorials.
  6. Use related:: Search for similar websites by adding “related:” followed by the website’s URL. For example, “related:amazon.com” will return results from similar e-commerce websites like Walmart and Overstock.
  7. Use advanced search: Access advanced search features by clicking the gear icon on the Google search results page. This allows you to filter results by language, file type, date range, and more.
  8. Use search operators: Familiarize yourself with Google’s search operators, such as “and,” “or,” and “not,” to refine your searches. For example, “chocolate AND chip AND cookies” will return results with all three words.
  9. Be specific: Use specific keywords and phrases to get relevant results. Avoid vague searches and try to include as much information as possible.
  10. Use Google’s built-in features: Take advantage of Google’s built-in features, such as autocomplete suggestions and instant answers, to streamline your search process.

ChatGPT And Other AI

Unless you live under a rock, you will have heard of the AI craze. The best way to search using ChatGPT or other AI platforms is to know what to ask, for example, if you could use ChatGPT to resolve a windows blue screen or a software error, simply ask ChatGPT how to resolve this error using the name of the software with the error code. It will give you suggestion and clues on how to solve the problem.

Example : How to resolve the 0xc00007b Blue Screen Error

Here’s a small list of AI search engine/tools :

Reddit

If AI is not your strong suit, you could search the answer to your problem on Reddit, put your question or error message in Google and add Reddit at the end of your query, or you could use the search bar on Reddit. Reddit is pretty powerful and millions of questions have been answered there, I would say it can be better than Google search at times.

YouTube

When you are not in a rush to get an answer or when you want to see how it is done, for example, you try to disassemble a laptop but can’t seem to find the screw that is holding the plastic cover. You can search “How to disassemble (laptop model)” to find your answer.

How To Ask Questions

Please Don’t Take This The Wrong Way, But…

Before you go around on the internet and start asking questions, you should always take a screenshot of the problem or a picture and note the symptoms. Always do your own research first to see if you can’t find any clues on how to resolve the problem. Always start with the easiest first like : Reboot the computer, is the cable connected properly. To take screenshot on your computer, you can use the prtsc (Print screen button)
