8bit computer status so far Okay, I’d like to give you guys an overview of the status of the 8bit computer build. (Also see video at the bottom of this post). The Memory modules First of, here’s the clock and the memory. I already described the clock module, the memory… Read the rest

Digital 25MHz DDS Dual-channel Signal Generator‎

Posted on2017-06-10

Digital 25MHz DDS Dual-channel Signal Generator‎ The latest addition to my electronics lab is a wave (or function) generator. It’s a digital one and it can, at least theoretically) be operated from a computer over USB. It features two independent channels, each of which can generate several wave forms: … Read the rest

8 bit Computer coming soon I ordered my first batch of parts with my favourite store, OKAPHONE ELEKTRONIKA. As soon as this stuff arrives, I will start the build of my own 8 bit computer out of basic parts, from the ground up! — Stay tuned, more will follow… … Read the rest

From STEM to STEAM

Posted on2017-03-05

From STEM to STEAM … and why that is important. STEM education For years there was STEM education: Science, Technology, Engineering and Mathematics. Some students loved it, most others feared it. It smells geeky, and dry, technical for those who are inclined to fear it. Lately we discover the reason… Read the rest

Working with both Arduino’s

Posted on2017-02-19

Working with both Arduino’s Okay, to work now. I’ve connected the pre-built VMA100 to my MacBook Pro to be able to program it. The separate ATmega328 chip from the barebone kit has been programmed as well. Power for both chips comes from the USB connection. The VMA100 UNO Has… Read the rest

Programming ATmega328 using the UNO

Posted on2017-02-18

Programming ATmega328 using the UNO Using these instructions, I managed to burn a boot loader on my ATmega328 chip from the barebone kit. Second step, I took out the UNO chip and slapped my barebone kit together on my breadboard with the 16MHz crystal and hooked it up using… Read the rest

ATmega328 UNO development board

Posted on2017-02-11

ATmega328 UNO development board The barebone kit I ordered yesterday is hard to program without an actual UNO. So today I ordered an ATmega328 UNO development board at Okaphone. The board is compatible to the Arduino UNO and it has been made by Velleman, which is an old and reputable… Read the rest
