Amazing how you can make a pretty interesting hobbyist electronics project video series barely tolerable.
Several things:
1) Why do Americans require a bland music bed behind absolutely everything in TV/web shows? It's always like a soulless 'rock beat' preset on a keyboard from Argos and all. What exactly is wrong with brief periodic moments of silence, or just the human voice on its own relaying relevant information? The fact that British TV now copies this, and the MTV-inspired ADHD visual format, makes me fucking despair. We used to do things right, you cretins.
2) Not only is 'Zed Ex' the thing's name, 'zee' doesn't sound half as good even if you allow for regional differences in pronunciation. There's zee, bouncing around like a loon with idiotic cheerfulness, while zed gives it a little subtly withering look, understated and cool as you like. Zed just naturally knows the score, and probably protects zee on the streets out of a sense of elder brotherly obligation. Zee would struggle to survive on Sesame Street without someone looking out for it.
3) Someone ought to tell him you really don't need to try so hard to be funny and 'entertaining', especially not with badly-performed pointless little sketches (watch all parts of his Spectrum project). It's okay to be a fairly dull, straight-laced nerdy guy telling us about your passion for fiddling with vintage computers and adapting consumer electronics for various purposes. Re-engineering this stuff can be engaging to watch in itself if you have an interest (and why else would anyone be watching these videos?), all that crap just detracts from the viewing experience.
4) This guy obviously really likes to keep his sponsors happy.
The actual compacted handheld end product is quite impressive; I liked that you could load games from inputting the original tape images, so you still got an authentic Speccy loading sequence for each one without necessarily having to attach a cassette player, which you could do if you so wished. So if he'd not been time-constrained and had gone through with all his original mod ideas, you could load games from the original tapes for a quick rave, and save them to a removable SD card.
Seeing it get pieced together from a combination of actual ZX Spectum internal organs and bits & pieces scavenged from other devices or bought off Amazon (with a spot of 3D printing and lasering here and there) was class, and the transparent back of the unit to see the inner workings was a nice touch. If this new Speccy they're gona start trying to flog us was put together with the same resourcefulness, modern ingenuity, and will to maintain the integrity of the beautifully efficiently-designed original system (i.e. an actual little modded working Spectrum in a new case, not just a Spectrum emulator), then it might grab me. A ton is still pushing it even then, though.
