Sharp don't seem to have the best reputation when it comes to graphing calculators however I do have a bit of a soft spot for them as they do have some interesting features.

My original TI-83 Plus feels like it's on its last legs.

Calculating the phase of the moon always struck me as a fun little program for a calculator, and with the current Artemis II mission it seemed like as good a time as any to look at a few example programs for this on a range of different calculators and po…

The Sharp ZQ-700 Electronic Organizer, also sold as the Sharp OZ-700 Wizard, was a pretty interesting device.

I've got a number of older computers that can print, but no printer for them.

Recent posts on here have taken a bit of a detour into Sharp Pocket Computer territory.

I don't think I've had a proper dose of "man-flu" since COVID and I haven't missed it at all.

I've been having a tricky time buying LM35DZ analogue temperature sensors for a project recently.

My latest eBay purchase was influenced by a desire for some practical test/prototype equipment, a bit of nostalgia and a desire to learn something new.

It's been quite a while since I posted about my Z80 Computer project.

When reading about the Cambridge Z88 computer and its available software I bumped into the occasional mention of Z-Tape by Wordmongers, a system that allowed you to back up files from your Z88 to a cassette recorder.
