With the Input, Output, and Core Panels done it was time to tackle something a little more challenging, the ALU. Since I had a small stash of signal relays burning a hole in the bottom of my parts bin (graciously donated to my makerspace Kwartzlab...
This is the quick hack of another code sample "Register writer" to play a warm up sound. The hardware is based on the schematic linked in the code. Works with Arduino Uno R3 aka: 328 compatible boards. https://pastebin.com/raw/FehmVLQS /*******************************************************************...
Time for another update. Mind you, at this point I am not documenting work that was already done in the past, but am following my actual development in real time. Therefore updates will be spaced much further apart, depending on how much time I can devote...
As noted above, the EXTEST instruction is not safe if you do not have the electronic schematic. For example, some unused pins can be connected to ground. Forced change of the state of such pins to 0 or 1, using the EXTEST command, can lead to...
UPDATE ================================================================This project occasionally outperformed my MoccaMaster mostly because of inconsistency in measuring quantities. I spent the time to dial in the MoccaMaster and it now produces...
Updates / Information For regular updates regarding class materials, follow wrongbaud and voidstarsec on twitter.Course Overview This is a four session course that covers the basics of reverse engineering software with Ghidra. For each session there...
Boian Mitov1:04 PMThank you @Usagi Electric (David) and @Dan Maloney :-) Usagi Electric (David)1:05 PMThank you all for the excellent discussion! I don't actually have any plans though, so I'll be hanging around a bit more, haha And although we have...
Summary I had a 'hard drive' (really, SD card) crash, and now I am in data recovery mode. I will have to rebuild the server. I will lick my wounds in the modern, containerized, way. Deets Youth I have run a home server for decades -- I assume...
Linear motion is a mode of movement where all three degrees of rotation are fixed and two degrees of motion are fixed so that an object can only move along one axis. This is how the bold on a dead bolt moves, how a drawer slide moves, and how a...
Today I'm going to take this nice looking Pacman desk lamp and mod it using an Arduino Nano. I'm going to improve its functionality and audio sensitivity. I'll only be explaining the code at a simple level, however the code is available below for you...
Timings are crucial! Let's check if we can go with a 4MHz clock using 70nS SRAM and the EEPROM. CPU timings First of all I want to try to recap CPU informations about timings from the WDC W65c02s datasheet. In the picture: PHI2: at 4MHz clock...
This winter we’ve been experimenting with our engraving process to lock down the best methods for different materials & cups. In this series I’ll be sharing some interesting tips we learned along the way in a small easily digestible format. First enjoy...
Software components Vintagephone software is composed by different parts. We have some functions to control the bells, the rotary encoder and the switch. We have functions that handle the clock methods, for setting the time and check the timer for...
Since i have a couple of computers and tablets I decided that i needed to find a way to share my most important files across all my devices. Instead of using a USB to sync them or having one of the PCs running as a server i found a more economic way....
I have been looking for a good mid range Dash cam for my car. I was thinking to integrate this to my custom build infotainment system. For this, there need to be some option to get live stream. I bought this DDPAI Mini Car Dash Camera from Amazon Link (Official...
