We have all see Nixie Tube clocks and at first this might seem like it is simply another. Well that is where you would be wrong. This clock is made using only tubes! “Also cold-cathode tubes, which found use in former times gladly in ring counters (organs, etc.), were not intended. The counting stages should be developed only with completely classical flip-flop stages. The 1-second pulse should be won most
Here is a nice simple LED light chaser from the Hacked Gadgets Forum. There is a full schematic provided, I am not sure if the author will be providing the chip code however. “4 functions triggered by the length of time control button is pressed. 1. Tap once to change patterns. 2. Press and hold for 0.5 seconds until 2 Leds start flashing then release. Unit will power off. 3.
Here is a cool mod to add a USB port to your alarm clock. “To add our USB power port, we’ll steal some DC voltage from the clock. We are going to run power through a LM 7805 voltage regulator to take it down to 5 volts. Adding a 220uF capacitor between the output and the ground can help smooth out the voltage if that’s a concern. We referenced the
1. Rapid Fire This rapid fire LEGO gun looks like lots of fun. This is what you need on your side when the next office battle breaks out. Well I guess the Nerf USB Cannon might still win the battle… 2. Remote Controlled Gun I need one of these for my front door. I can see who is there and get rid of them if I don’t want to talk
If you are looking to make a DIY PIC chip Frequency Counter check out this site. There is full instructions on how to make your own. “The circuit diagram is so simple that I didn’t make a complete Eagle schematic for it yet (other builders did, see links). The first prototype was built on a breadboard with round pads. A very similar design could be used for a single-sided printed
Well I think someone was thinking about selling a uinique product to a niche market. Someone better tell that engineer that the niche market needs to be greater than 10 people. “There isn’t much to say about Atech’s iCarta iPod dock and Bath Tissue Holder. No joke; someone actually made a speaker system for the iPod with a toilet paper holder attached. The iCarta’s sporting four speakers, a charging iPod
1. 32 RGB LED Magic Ball With a bunch of RGB (Red Green Blue) LEDs you can make a real cool display. This one was made using a Microchip 16F628 microcontroller and serial to parallel converter chips since the 16F628 doesn’t have 32 outputs. 2. SPIN Talk about life size. The SPIN display is massive and has a nice effect. “We’ve all seen a train or a car whizzing past
