At this time, you can go and find a refill that has been used, and then go and remove the front head and replace it with this one. Then let him use it for a while to get the ink out.
-
If you want a low-cost solution, I think you can only buy a new pen, which is the best, because like a fountain pen, it is not expensive to buy a **, don't buy a too expensive pen.
-
This is gone, it's a piece when it's used up, and what is a low-cost solution, if not, you can change a refill, so that you can continue to use it!
-
I can only buy a pen.
There is no way to use a pencil without dropping the ball.
-
The ink goes bad before the beads are used, is there any low-cost solution? Then you can get the water out of it, so that it can be used as a brush word so that you can write. Written.
-
If the ink is not used up and the table is broken, then I think this kind of is too bad, and you can buy a better quality again.
-
This bead cannot be replaced, so you will have to buy a new refill.
-
If that's the case, you can. Buy some refills and press them directly on the pen, so that the cost will be lower.
-
If the ink is broken before the beads are used, you can take the head off the head of another used ballpoint pen and put it on the broken ballpoint pen.
-
If you don't run out of ink, the beads on top of you will break, and the easiest way to do this is to put the tip of a pen that has run out of ink on top of this.
-
The ink didn't run out of beads and it broke, well, there was no low-cost solution but to throw it away.

Learning hardware, of course, is to go to the forum of zol or the Pacific Ocean, insist on a month, basic entry, insist on 3 months of basic proficiency, the most important thing is to install it repeatedly by yourself, and first take your own computer to practice.

1. First of all, we must consider our own endurance, do what we can, and formulate a total range;
2. Consider the appropriate model in combination with the use, and it is almost enough;
3. Then decide what type of CPU to use, and then decide other corresponding components;
4. All hardware should be selected from first-line or second-line brands;
5. Listen to the opinions of the merchants, mention a few more whys, many of the merchants' suggestions are also kind, but you should pay attention to distinguish;
6. Misunderstandings in purchasing:
a) It is not that the higher the configuration, the better, because the configuration is high, the power consumption is also large, the heat is large, the parts are also more likely to be damaged, and the overly high configuration can not be used, which is also a waste of resources;
b) Hardware elimination is also very fast, do not pursue one-time in place, new products are always coming out, it is impossible to achieve a single sex in place, today is the highest configuration, tomorrow will be behind.
7. When purchasing, it is also a better way to bring a friend who is a little good at hardware to help reference.

Your question is too general, it seems that you still lack knowledge of hardware, give you a ** first make up for the lesson.
If you don't know how to choose, you can go to the simulated PC building section to take a look.
Today's hardware is not in the past, not necessarily bigger the better, such as CPU, it depends on the architecture, interface, power consumption, cache, frequency, as well as support and optimization of other hardware, etc., such as power supply, the same power supply also involves the problem of conversion rate, motherboard, the same model of motherboard, but also depends on the materials and power supply, I hope I said so much to inspire you.

Familiarity with the computer market is required**; Develop a computer assembly plan; Be able to purchase and assemble the hardware equipment required, and be able to reasonably configure and install computers and peripherals; installation and configuration of computer software systems; maintenance of hardware and peripherals; Clearly describe the computer hardware and software failures that have occurred. Learn and master IC design, circuit design and PCB cabling standard specifications, proficient in using various simulators and PCB cabling software, to achieve the level of analysis and debugging operations.
1.Component options, schematic design.
2.Commonly used EDA software. For example, PCB, Protel Orcad, PowperPCB, Maplux2 ISE General PCB board engineers and EMC engineers do this.
Improvement: 51 ARM, DSP, FPGA can be learned.

Circuit knowledge, analog electronic circuit knowledge: As a qualified hardware engineer, analog circuit knowledge is the foundation, starting from understanding the most basic resistors, capacitors, inductors, diodes, transistors and other components, we need to be familiar with some basic analog circuit design methods. For example, simple amplification circuits, addition and subtraction circuits, circuits with triodes as switches, etc.
In particular, the basics of circuit voltage division and power calculation are used every day.
Circuit knowledge, digital electronic circuit knowledge: As a qualified hardware engineer, digital electronic circuit knowledge is also a foundation that we need to master, digital electricity is relatively easy to learn or understand than analog electricity, to understand some commonly used gate circuits, flip-flops, timing relationships, etc.
Application of microcontroller and microprocessor: As a qualified hardware engineer, we often have to design microcomputer and some microprocessor electronic products in the future design circuit. This requires us to have the foundation of the microcontroller, understand the internal working principle, and some functions and how to use them, peripheral circuits, etc.
The commonly used basis is the 51 microcontroller, or some processors of the ARM series.
Use of EDA software: As a qualified hardware engineer, we have to learn to use some commonly used EDA software, such as Protel, AD, PowerPCB and so on. Because the schematic diagram and PCB of the designed circuit should be drawn with EDA software, and then the board should be made.
Familiar with commonly used test tools: As a qualified hardware engineer, we must learn to use the most commonly used test tools, the most commonly used multimeters, switching power supplies, oscilloscopes. More complex ones include network analyzers, spectrum analyzers, signal generators, etc.
The use of commonly used test software: such as serial port debugging assistant, or network debugging tools, some analysis circuit software, etc., these are our commonly used tools.
Writing of embedded software: When doing a single-chip microcomputer project, the test software needs to be written after the hardware is designed, and capable hardware engineers can generally write embedded test software. In this way, the basic functionality of our hardware is tested through software.

General knowledge is that you just need to know which is good, know how to distinguish numbers or something, you can try to match a computer yourself, I asked questions here a few years ago like you, but no one said the point, and then I just need to match the machine, just this time, almost all the knowledge of my computer hardware is understood, you go to Zhongguancun first, and then limit yourself to one, for example, 4000, you will not exceed this**with the machine, then you will be able to understand the motherboard socket, What is better than i3 is CPUI5, not only the problem of the main frequency, but also why AMD's CPU can't compare to the i-series.

Like a graphics card. 7750 is better than 6750.
The newer the graphics card, the better...
But it depends on what you want to do with it.

Of course, reading is useful, but the result is your own ability, even if you are a doctorate, you are not capable, it is not the same, maybe you say that some people are still capable without reading, but you want to be a minority after all, will you be that minority? One thing you have to remember is that it's better to read a book than not to read it at all.
Many people use beer to wash their hair, because the home remedies for washing hair with beer are believed to have been widely spread, but for various reasons, there are still many people who have the question of whether it is okay to wash their hair with beer! >>>More
