“These transit tokens from New York were discontinued in 1980 and have now been recycled into cuff links, courtesy of their designer Ward Wallau. He spent 11 years petitioning the NY Transit Authority before they finally gave him permission to use them in his jewelry, making them truly special. These unique cuff links are also available with recycled transit tokens from Boston, D.C., San Francisco and Chicago.” These might be fun to make, perhaps out of arcade tokens…
NotBobVilla sent this along…“A Sheetrock lift I designed/built on a job site of a 6 story building I renovated. I built 2 of them they worked so well. We also had about 30,000 SQ/FT of ceiling to put up. Typically when someone talks about a sheetrock lift its 2×4’s fashioned into a Tee. With 2 to 3 guys struggling to screw it to the ceiling. This is a one man operation. Material costs $50-60 bucks 4-6 hours build time. We could have bought one but weres the fun in that? It works just as well or better as lifts costing $600+”
Chris writes “Getting your hands on an good sector panel antenna is not easy – if you live in Saudi Arabia.

Master modder Ben Heck has created a masterpiece “Of all the portable videogame devices I’ve ever built over the years one system has always been my “Holy Grail” to make – my “dream portable” if you will. (Yes, even more so than my Neo Geo arcade machine) And now after a couple years of tinkering it is complete! Without further ado – the Atari 800 XE Laptop!”
