Great little calculator and quite helpful.
This was a really cool kit to build and resulted in a calculator that is very useful for calculating color codes, converting bases, and as just a normal calculator. The display is easy to see and assembly is not hard.

Works
Good practice. The additional features are a fun addition and have actually used them. Having to cut the numbers out by hand kind of annoying

Double check resistor values!!
Went together fairly easily, my only complaint is they sent the wrong value for the R5 resistor. It is supposed to be 330 ohms, the one they sent was 2.2k ohms. I had already checked and installed the other resistors so I assumed by the process of elimination the remaining resistor was 330 ohm. When I powered it up the first time the display was so dim I initially thought it didn’t power up. The instructions do include a small trouble shooting section. It said to check the other resistors, which were in the right spot and measured correctly, or to check the batteries, both measured 1.5 volts. Checked R5 just because it located right beside the display mount, yup, almost ten times more resistance than the circuit called for. Fortunately this is my fifth or sixth kit so I had some extra parts from previous kits and luckily a 330 ohm resistor was one of the parts. I managed to get the resistor unsoldered and the correct resistor soldered back in without destroying anything. Had it not been for the wrong resistor it would have been 4 stars.

A useful item at a low cost.
It came with a few extra resistors that aren’t used. The instructions are complete and easy to follow. Tje display could be a little brighter. It works well at converting Hex to and from Decimal. It also works well at reading color codes on resistors to the proper value. I enjoyed building it and will use it.

Fun kit that is actually useful
I had fun putting this kit together. I’ve soldered many little kits like this and im happy to say I have been using the calculator on my desk for small calculations. To make something functional and useful and then actually use it in your daily life is a cool feeling. While this is no TI-84 the backlit screen and bonus functions make this a lot better than store bought calculators in the same price range ($10). The only downside is the batteries are really hard to access if they need to be changed – you need to take the back off and screen out to change them. I am thinking of soldering some wire to the leads of the battery connectors to move the batteries to a more accessible place. Overall, its a fun kit but I do recommend you have soldering experience before attempting.

Works great
As an electronics enthusiast, I recently embarked on a soldering project with the 7 Digits Desk Calculator Soldering Project Kit. The kit’s material quality is commendable, and being someone who enjoys challenging projects, I was immediately drawn to the idea of assembling my own digital desktop calculator.The kit includes all the necessary components such as the circuit board, display, buttons, resistors, capacitors, diodes, and integrated circuits. Detailed instructions and a comprehensive materials list accompany the kit, making the assembly process straightforward.Following the step-by-step instructions, I meticulously soldered each component onto the circuit board. The entire process took approximately 2 hours, during which I frequently referred to the manual to ensure the correct installation of each element.The calculator boasts full functionality, capable of addition, subtraction, multiplication, division, square root, and percentage calculations. It also features a memory function for storing and recalling results. The display is clear and easy to read, and the buttons offer a satisfying tactile feel. It proves to be an excellent project for electronics enthusiasts to learn and practice soldering skills.While the kit is overall well-designed, the instructions could be clearer, requiring careful reading to fully understand.The solder points on the circuit board are small, and the components are delicate, necessitating the use of a magnifying glass, fine solder, and a precise soldering iron.The calculator’s precision is limited and may not be suitable for highly complex calculations.Aligning the calculator’s buttons with the panel’s openings proved to be a time-consuming task, requiring adjustments to achieve proper alignment.

After completing board and kit, Calculator didn’t power on. Disappointing.
I liked the detail instructions sheet, however after completion of the kit, the calculator screen would light up and nothing else would happen.Very disappointing.

Not just a calculator
These days, who needs a calculator when you’ve got one built into every smartphone? This one, however, does something no other pocket calculator does (at least not any I’ve seen): punch in the color bands on an electronic resistor and it will tell you the resistance value and tolerance. If you’re an electronics hobbyist with a box of random resistors on hand, this thing is great. Assembly is a tedious process (since all of the key switches have to be soldered to the board in addition to the other components) but other than a minor bobble in soldering (bridged two pins on the IC socket, had to fix that) it went smoothly.
