    Bacon and Tatos

    You might try par-boiling the potatoes before you fry them. With a nice red or fingerling potato cut into cubes, it won't take too much time--place the pot of water on heat before you start. Cut the potatoes first, drop them in salted boiling water then proceed to cutting and frying your bacon.To get a crisp shell without drying out your potatoes, you could par-boil the night before and refrigerate. But for a quick breakfast, I think that you will still save time if you par-boil the potatoes so the water does most of the work and frying in grease makes the outside crispy and takes the inside the rest of the way (Rinse under cold water before you drop them in the grease--dry them off as well so you don't get splatter)

    How to make a Bo Shuriken.

    So, if you get your steel rod from a big box store, you probably won't know what type of steel alloy that you are getting. It's probably going to be a mild steel (low carbon) that you can use for pins, threaded bolts.Probably cold rolled which does harden the steel somewhat, but it's never going to resist bending like a good tool or spring steel. If you are grinding the tip of your spike and let it get too hot (can happen quickly on those grinders), you are going to ruin any hardening from the manufacturer.At the very least, keep a cup of water handy and cool down the spike between grinds. If it changes color, you have let it get too hot.In general, you can heat up the tip and quench it, but every type of steel has a recommended process for how hot and what to use to quench (oil, water,...see more »So, if you get your steel rod from a big box store, you probably won't know what type of steel alloy that you are getting.

Order it online and you can specify what alloy of steel you want and check from the supplier or manufacturer what the recommendations are.Here's a materials sheet for O1 tool steel: https://www.speedymetals.com/information/material9... as an example

    Any updates on this instructable? It looks like you got quite a few new hits from the mailer I got from instructables.Interested in knowing how your parachute experiment worked. Seems like a vertical launch tube with a spring driven piston and pin retention (pulled by a servo to trigger) could be more efficient and avoid some of the timing issues with stopping the prop. Also seem like you should insert a leader to move the shroud lines away from snags.Was interested to see how your launch ramp worked out. It looks like you were aiming for a boosted launch, but it seems like without rollers or bearings you might bind up using regular sliders for those extruded rails. Maybe even two slides made from delrin would be enough to keep the shuttle from binding and survive smacking a stopping...see more »Any updates on this instructable?

    DIY Portable Mini Monitor

    He has a separate project to re-use a laptop screen: http://www.instructables.com/id/How-to-reuse-the-o...The main problem is that you have to match the hardware and lcd driver code to your screen so your options are limited to finding a compatible controller board with the right software installed. From there, it's more of a construction project than an electronics project, but you can take the lcd, replace the backlight with something more powerful and then expand into smart mirror/window projects
