First thing that I have to decide is to find uC, that suits my needs. My requirements:CheapHave some sort of hardware communication (bitbanging would consume scarce CPU time)Have sufficient internal memory. To be more specific:Initial hash value:...
The first step is to remove the existing W25Q128 flash device and replace it with some pin header to connect up a custom board. The 1.27mm pitch SOIC-8 package is pretty easy to remove. First start by cutting each of the eight pins with a...
Hardware hackers love their test equipment. There are entire forums dedicated to talking about multimeters, oscilloscopes, signal generators, and other common bench tools. At times it seems we spend more time talking about our tools than actually using...
Having run out of screws to build Cub with, I'm now looking into the Naze32 AI pilot. Connecting everything up properly is the first order of the day. Everything is pretty much taken care of by the board, its VBat input takes up to 36 volts and it has...
I have received the machined lid and chassis back from Descher Automation They did a fantastic job machining away the parts of the chassis I didn't want and putting the features in the lid for mounting the PC-104 and the SSD. They even made a drawing...
Working on a flow sensor test setup the breadboard suddenly exploded! And I though blue smoke was the worst that could occur.. ---------- more ----------Yesterday I made a great step forward testing the flow sensor. I made a simple breadboard setup to...
There was a completed version of the video system running a few months ago. Pretty much everything changed during the main software development and that also included the video modes. One change was to add the classic 60Hz VGA mode and allow even the...
When considering the keyboard layout, one has to think about what keycaps are available on the market. Those low-profile switches use non-standard keycaps, so I'm a bit limited. A quick search of Aliexpress reveled that I have a huge choice of 1u caps,...
Ok, I haven't touched this project much since my classes begun this year, but since I have started it I had 2 ideias for this project that meet my goals in one way or another.I have concluded that I can make the case 50% or even 40% of the original IBM...
The PCB has several I / O connectors common to all projects: VGA + MonochromeVGA integrated2 x DB9 ports to be used as serial ports or as joysticks Additionally, each project can also add a Hat I / O board by adding other specific connectors. For example,...
Well, I lied, because projects like this one are never actually finished. But let's say I'm not going to do any major rework from now. It took one more board revision and a little bit of coding to come up with final hardwareIn the meantime, I made some...
When you spend 1/10 the cost on a spa, you have to wonder, what are you giving up? Jets (the portable units have bubbles - impressive, but not the same)built-in seatsbig, long-lasting filtersinsulationheater power The first 3 aren't a big deal....
Demo Background I am electrical engineer by trade, but in my spare time I like to make custom toys for my kids, particularly my son Ethan. Ethan has autism and sensory needs, which make most store-bought toys challenging for him to play with appropriately....
The foundational base for this project required some sort of oven. From the design perspective, I needed an oven, preferably one with a good heat-up slope, a temperature sensor, a solid-state relay that was capable of handling “house-hold”...
