I'm here doing some inventory for my breadboard CPU project https://hackaday.io/project/162659-8-bit-breadboard-cpu , labeling and organizing all these IC I've ordered over the last few weeks. I also ordered a few 6809's for a potential future...
I'm working on my 8 bit TTL computer (https://hackaday.io/project/162659-8-bit-breadboard-cpu) and have just received a sack of 3 pole switches I ordered. I'm using them to run the control signals for testing all modules working together. ...
Working on my TTL CPU project https://hackaday.io/project/162659-8-bit-breadboard-cpu . I'm working on wiring up the first block (the XY register). I have 8 x 8 bit bus drivers for the register. I started using 74ACT241's for...
Working on my 8 bit TTL CPU. I've got a version of IRQ working. When IRQ is pulled low, it loads the IRQ instruction (FF) into the instruction register after the current instruction is finished. I am trying to figure out the simplest...
NOT THE ESP32. I don't have those and I don't want them. Yet.I *do* have a couple ESP-12E boards. I don't have much (okay, any) experience with them yet, but I cant imagine an 80MHz almost-ARM-ish microcontroller would let its butt be kicked by...
If I'm not using this Stack thing correctly, excuse me! I recently gave Arduino smooth volume control of it's Tone() functionality with nothing but a speaker. :)
In this column we discover what happens when we connect multiple resistors in parallel; that is, side-by-side (spoiler alert, we end up creating a current divider).

Did you saw the last version of Eagle Ver 8? https://twitter.com/ADSKEAGLE/status/830126923539939328After a quick review, I found some major changes:-You must sign-in/create an account in the first run of the free version.-A new tool called "Past...
I am trying to understand how to fill out the FW-8-BEN form for International winner (ideally Canadian). The difficult part is section II Claim of Tax Treaty Benefits - Special rates and condition.Should I just give up and let them classify...
Eligible projects have a Microchip part on them- an opAmp, a PIC, whatever, and must be a new entry into the Hackaday Prize after 7/22/15.More details here.https://hackaday.io/page/1116-win-the-curiosity-board
