I did try “ringing” the Addmaster 01 Hotline number – but strangely no one answered. So I repaired and restored this vintage 1972 Addmaster calculator myself. It uses an early gas discharge “Panaplex” orange display. #VintageElectronics #VintageCalculator #Panaplex

I'm displaying 3D mesh shapes in this C# app on this repaired/restored #VectorScope from the 1970s. Combining new and old - a match in electronic heaven. #3Dgraphics #programming #electronics

Transistor checking using the 1970s made, and the more recent homemade. Can you guess which one is newer?

Great for testing rebranded #Z80 chips from China.

Did I watch the FCukup this weekend? Of course not! Instead, being an uber-geek I built this Z80-MBC2 board and revisited the groovy 70s computing era. Definitely a nostalgic trip down computer memory lane.

Just repaired and restored this 1973 Sinclair Cambridge Type-2 vintage calculator. It uses a TMS0801NC calculator chip by Texas Instruments which requires -10V and -15V supplies since it is a PMOS device.

Forget #ChatGPT and Python! Back in 1993 we used C++, 5¼ floppy disks, and a lot of blood, sweat & tears to train a neural network. https://www.i4cy.com/xor_nn/

The Bailey Borwein Plouffe (BBP) algorithm for calculating π was discovered by Simon Plouffe in 1995. Check out to see how well it performs.

These lovely ladies certainly convinced me to buy a #vidor #battery.

Finally go around to having a go programming this smart TTGO T-Watch using PlatformIO and C++. My code does nothing fancy, just a simple watch designed to prolong battery power and synchronised using an NTP server.
