Glad you got my package, just picked out a few things I thought you might enjoy. The Knipex knife is called a "Cable Knife" and is mostly a tool for electricians. No, I'm not sick of your big knife, just thought you might enjoy a couple of variations. The Martor safety box cutter is also very useful as a letter opener. BTW, the multi-meters were still working last time I put batteries in them, they were being thrown in the dumpster during a lab cleanout. You will notice the Philips still had an old Westinghouse tool control label on it.

Tape some of those solar cells to the road, maybe you'll get a few million in grant money :D

Also wow, definitely gonna grab one of those Pi to DE0 boards, that's pretty neat
edit: dammit, the kickstarter was unsuccessful :( nooo

[IgnazKevenaar]

Sand in small glass fuses is just to change the reaction speed by changing the thermal capacity at the fuse wire.

[DoRC]

can you start opening packages with a 2 hand sword?

That is a National Instruments LED bubble display. Logo in on the top right of the unit in copper fill.

That pale yellow Radio spares box really takes me back, before RS got all bright red and jazzy

We have got to see the Crocodile Dundee knife keep its place of honor!

[MOTOSNOWRIDER]

Those Knipex channel locks are a super slick tool! I'm a wireman in Alaska and they have gotten me out of a few sticky situations! Those and my Klein "11 in 1" screw driver are some of my two most used tools in my box!

31:50 love that old-school 2-plate printing with the black and the sort of reddish-pinkish-brownish.

one way to reassemble a device that uses heat-staked posts:
slice off the heat-staked portion, then use tiny self-tapping screws right into the posts.
the thinner the screws, the better, else the posts may crack, which gives a lousy attachment.

Loved the solar stuff - especially the solar powerbank! Such a simple but brilliant idea.
Didn't like the cruelty to the to multimeters - ripped apart with no thought of trying to repair or preserve them. Shame on you Dave :P

The O'tatmo lighted bracelet thing would also be popular with athletes/fitness enthusiasts who go running/jogging before daybreak or at/around sunset along public streets/roads. And cyclists.

A few years ago, I bought something similar, but instead of a clasp, it used a spring to wrap around one's arm or leg. After using mine around the leg of my trousers to starve the cog/chain on my bicycle, it fell off and the spring was damaged when a car drove over it behind me. I picked it up and later extracted the light circuit and light pipe and affixed both (as a unit) to my brain bucket (bicycle helmet). Mine is a single color - red.

my mailbag hunger has been satiated. please do not wait so long in between episodes! thanks, Dave!

[RobertSzasz]

only 1-4 Watts per meter? That's pretty abysmal. The price per linear meter would have to be way under 1 USD to compensate for the larger area needed.

So what exactly is a sav and why is it so frequently sucked?
