slide projector microscope
Hi, in this manual I will teach you how to turn the slide machine into a microscope.
It\'s relatively easy to do. You\'ll need; 1-
Slide show 2-knife(
Preferred operating knife)3-an onion(my sample)4-forceps(
I used a pair of tweezers)5-
Slide 6 projector-
Free time 7-10 minutes(optional)
A solution of Blue (
For dyeing samples)
Type 1 that can be ink blue with a pen-
Cut the onion in half after scraping it.
Cutting a piece of one of the concentric rings-
Remove the internal white film of just cut 4 pieces with tweezers
5-dye the sample with nail blue solution or tap water pen ink
Keep it dry for 5 minutes 6-
Turn on the projector slide and put the sample in 7-
Close the slide and pop up in project tor8-
Turn on the projector and adjust the focus to get the best performance to clean the lens of the projector, the higher all these lenses and the curved mirror behind the lamp, the better the projector lumens (
Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
