ATtiny USB Web Site Hit Counter Project

at 4:52 pm. Filed under Complex Hacks, Computer Hacks, DIY Hacks, Electronic Hacks


How many hits does your web site have today? You just need to log onto to your stats system, drill into a few menus and voila there it is. This ATtiny USB Web Site Hit Counter Project by Bob Hobby makes it much easier than that, you can just have a look at the numbers on your own hit counter panel, if you are curious how traffic changed based on updates and time of day this would be a great way to keep an eye on things. It is based on the AVR ATtiny which communicates to a host computer to get updates. The host computer gets the updated stats from your web site which runs a tiny script to keep track of your hits. I can think of lots of fun things to add to the project such as adding a tiny beep for every 1000 visitors or flashing a strobe if you reach a new record for the day.

How a Slingshot works

at 1:39 pm. Filed under Insane Equipment


See the world record holder in hand held slingshot in action and learn how a slingshot actually works. Tobias can actually generate over  100 jules of energy with his slingshot. That is some amazing power as you can see it can punch through some very thick boards. Destin from Smarter Every Day shows us that you get the most energy from a slingshot if you pull back and fire right away, if you pause with the rubber bands stretched they cool and loose power.

Halfluck Automated Brewing System

at 5:14 pm. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks


If you enjoy a beer or two every now and again you might want to try your hand at making a few batches of your own. After you get good at it why not automate the process. That is what randyrob did and has since had his system make over 1000 liters of beer. Got to love the NES controller that he integrated into his control system! Best of all he has provided the Arduino source code for everyone to play with.

Gravity Bike Build

at 12:46 pm. Filed under DIY Hacks


A gravity bike is a bike that has been modified to run at high speeds by using a hill and gravity to get you going. There are no other means of pedaling the bike so you need to make sure your hill is long enough and high enough to get some good speed. There are lots of variations to the designs but most of them have the rider in a low center of gravity position, most have added frame structure to ensure a safe ride at high speeds and massive brakes to stop. SIN Cycles have built a number of bikes and they walk through the build process of their s1 gravity bike in one of their blog posts. You can see the s1 in action in the video below at the 1:30 mark and a crash of the s1 at around 1:50. 🙁  Doesn’t look like the damage is anything that a big hammer and a welder can’t fix though.

Ping Pong Balls in Space

at 1:35 pm. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks, Funny Hacks, Insane Equipment


This Kickstarter will get 1000 Ping Pong Ball Projects into Space. Many of them will be student projects but there will be a bunch from non students so if you have a great idea you might be able to get it into space. There are some cool sponsorship levels such as getting a note into space and back for $10. I was wondering how many they recover since they say that they can be spread out up to 200 miles from the launch site. A tiny ping pong ball that is can be painted by the participant might be quite difficult to find, hopefully none of the kids choose an army camo theme for their ball. After further reading it seems that the balls will ride down in groups that are placed in a rack that can be tracked.

“We will launch the PongSats from the Black Rock desert in Nevada. The vehicles that carry them are called High Rack. They are made of foam and carbon fiber. We have four separate telemetry links to the High Rack tracking it during the flight. At the end of the flight we release the balloon and the High Rack descends by parachute.”

DIY Voice Activated Video Recording Project

at 2:21 am. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks


If you have a camcorder you have probably had a case where you needed to start recording but weren’t near the record button. Ragtop from the Parallax Forum built a DIY Voice Activated Video Recording Project that monitors the room noise using a small microphone. When the room sound level is high enough the system sends out an IR code using an IR (infrared LED) that simulates the record button of the remote control for his camcorder. Only issue is that the record button is both the record and stop recording function and since IR is line of sight is something gets in the way of an IR transmission the system could get out of sync. I wonder if there is a hidden code that allows for record and stop functions instead of a single record/pause signal. I remember when programming some components into my Harmony remote some equipment had a bunch of remote functions that were not accessible with the remote that came with the device such as turn on and turn off, the remote only had a single power button.
