What is the deadline? How much time do I have left?

The deadline for the final project is pretty much 20th of June, as my presentation is on 21st of june, so I need time to make the slide and the demo video. Fortunately I got everything ready well enough in time, that I was ahead of schedule. The ultimate final deadline is on 28th, when the repo closes and even if I get something further done, I wont be able to upgrade the repo with the details.

what tasks have been completed, and what tasks remain?

I 3D designed and printed the case for the final project, I have lasercut the window for the case and the battery compartment door, and the end plate, that lets people use their preferred connectors. the circuit board was designed and milled twice, and the 3rd generation board was the one in use in the demonstration video. Programming was the last thing to complete, because of getting the proper chip took more time than anticipated. The one task that I didnt have time for, was to cast and mold the probe handles, but I expect to have them done and documented by the time repo closes.

As an additional task, with only cosmetic effects I could give the casing an acetone vapour treatment, this would make its 3d printed surface look smooth and glossy. But this is a cosmetic thing, that I would do more for the experience and I dont believe it would matter when being evaluated.

how will I complete the remaining tasks in time?

It took me a while to get the information that molding and casting the handles for the probes would be desirable for evaluation, but they should be done well enough in time to meet the June 28th deadline.

what has worked?

I managed to get the voltage measurement, the shortcircuit check and the current measurement done. The display works as intended, the button cycles through the different features.

what hasn't?

resistor and capacitor checks, with resistor the problem was that I couldnt get the math right for it on time, and the value kept changing constantly because of the USB powersupply being so unrealiable. With Capacitor the problem was how to connect it safely, for the testing purpose the idea is that the capacitor is plugged in and the multimeter tests it. This is a hands off thing, because of the power some capacitors can hold, and because it takes a moment. the reading fails if the probes slip off the capacitor during reading. Developing a solution for this would have taken more time than I had for the final project.

what questions still need to be resolved?

Can I further minimize the reliance on components outside of lab inventory? Right now the main chip, the current measurement, the banana connectors, the voltage division board for the battery power, all came from external sources and are not in the lab inventory.

The general goal of this project was to be as simple as possible to build, and having to rely on components that are not in the lab inventory complicates things.

what have you learned?

That I have to pay attention to the components I use to make my boards, I had to get the proper chip for its cpu because I had made the design for it, and not the one chip in the lab inventory.
