For a more in-depth understanding, here’s a short video on how to build a better DIY desk lamp:
2. DIY Electronic Home Computer
Have you ever tried to wonder how computers actually work?
Think about this. Computers are just another electrical/electronic device, just like a light bulb, consisting of static bits of silicon and metal.
When correctly assembled, these tiny electronic components can effortlessly store and manipulate information and data – and they can even have a significant impact on the real world.
After thinking about all these, we figured out that you can actually make your own DIY electronic home computer as part of our DIY technology projects.

Therefore, if you want to build your own DIY electronic home computer, you’ll simply need a simple motherboard and some of the components listed below:
Things You Need
- Motherboard: An Intel-P4 motherboard with processor and RAM (memory)
- Data cables: You can get all the SATA/IDE and USB data -cables
- Power cords: Power-cord for your PC and monitor
- computer mouse
- hard-drive (168GB)
- A good 19.5” monitor
- ATX-cabinet with SMPS and power cables
Open one side of the cabinet (the other end is sealed) and place the motherboard on the opposite side (sealed) slot. A gentle press on the four sides of the board can lock it onto the slot.
You will find a four or eight pin connector on the motherboard. Plug in the power cable into the pin slot.
Take the hard drive from the box and place it into the HDD slot in the cabinet. Push it in until it locks into the slot
Connect the Power cable from the SMPS to the HDD, the black end connects to the HDD, and the white end is at the SMPS
Connect the Data cable from the HDD to the motherboard pin
Close the cabinet
Connect the Mouse and Keyboard to the USB ports
Connect the video card to the monitor
Connect the power cords to the SMPS and the monitor plug them to power sources
Turn on the computer
The standard hard drive comes with an inbuilt Windows for a home operating system. Now you can start using the system for your simple home applications.
Here’s a short video guide to make it easier for you:
3. DIY Electronic Stereo Mixer
This simple passive DIY electronic stereo mixer displays resistors in use.
This simple stereo mixer will let us combine two stereo tracks into a single track, while also adjusting the volume of both tracks together and individually.
Let’s quickly get started.
Things You Need
- Five Stereo input jacks (274-249)
- One ALTOID Tin box (rectangle shape with two inches height and ten inches length
- 22-gauge bare hook-up wire (One foot in diameter)
- 8 1KOHM resistors (with 1/8 power rating)
- 2 small size nose-pliers
- One wire cutter
- One caliper
- One soldering gun
- Permanent marker
- Ground wire
Draw a center line across the ALTIOD tin box sides. It should be at a distance of 0.25″ from the base on both sides. You can insert the input jacks on the longer side of the tin and the output jacks on the shorter side of the tin. You can use a pencil or a permanent marker.
Make four holes along the length of the longer side of the tin. They should be at equal distances from each other. Make one hole each on the shorter two shorter sides of the tin box. You can use an electronic handheld driller. The diameter of the hole should be preferably 0.25”.

Insert all the stereo jacks into the holes from inside the box. Make sure you have removed the retaining nuts from every jack before inserting.
Find the ground tab on the last or first jack. Connect the bare-22-gauge wire to the jack’s ground tab. Use the solder gun and solder the two with each other.
Your next task is to connect the rest of the wire to each ground tab on the other jacks and solder. Complete the soldering and insert the retainer nuts onto the jacks in their original positions. Fasten the bolts tightly onto the jacks. You can use the nose-pliers to bend the wire and draw it through.
Take one resistor and connect it to the center tab of the output jack tab in the tin box that is nearest to the input jack. Solder the resistor onto the jack.
Connect the other resistors to the mid-section of the other input jacks and solder. The lead of each resistor should connect to the previous resistor. The first resistor should connect to the center-tab of the output jack.
Connect the next resistor to the mid-section of the output jack which is close to the input jack. Solder. Connect the other end of the resistor to the outer-tab of the first output jack.
Connect the outer-tab of the first input jack to the resistor on the outer jack. Continue the connection until all the outer tabs of the input jacks are connected to the outer-tab of the output jack through the resistors. Solder every connection.
Connect the music player output to the input jack of the tin box. Connect the output jack to the speaker.
Now, you can play music. Experience the difference in sound output. It will be much higher than the ones you ever got before.

4. DIY Electronic Night Lamp Jar
This gorgeous DIY electronic night lamp jar provides a warm, soft glow in the dark so that it can be used anywhere – hallway, bedroom, sitting room, dark stairway – or in any dark place!
Things You Need
- Large or medium glass jar
- One Toroidal-Transformer
- One NPN-Transistor
- One Photo-Transistor
- One LED light
- 10k Resistor
- The 2-meter thin wire used in electronic circuits
Connect the positive side of the battery to the one end of Toroidal-Transformer. Usually, it is one of the three copper coils. The recommended practice is to solder the wires.
Connect the second end of the transformer to the NPN-Transistor. The recommended practice is to solder the wires.
Connect the third coil of the transformer to the 10K resistor. The recommended practice is to solder the wires.
Connect one end of the resistor to the NPN-Transistor and the other end to the photo-transistor. The recommended practice is to solder the wires.
Connect the other part of the NPN-resistor to the one end of the white LED. The recommended practice is to solder the wires.

In the next step, you have to connect the negative side of the battery to the Photo-Transistor, NPN-Transistor, and the second end of the white LED in parallel. The recommended practice is to solder the wires.
You need to use a breadboard to make the installations, so it remains stable. You can seal the bread-board to the small wooden board. Now you can insert the assembly into the glass jar. You may choose a colored glass to increase the visual effects.
The phototransistor can detect daylight from the exterior of the jar. When you take it into a dark room, the LED starts glowing since the circuit is closed. When you bring to the daylight, the circuit opens, and the LED lamp stops glowing. So, you don’t need a switch to turn on and off the light.
