Digital Display Updates the Look of Old Power Supply

 Digital Display Updates the Look of Old Power Supply


xrunner had an old Heath power supply. He changed out the original capacitors to some larger Nichicon units. That would be been enough but the addition of some inexpensive digital displays will make this unit look a bit more modern. Nice inexpensive upgrade but it will ensure this power supply will be usable for many years to come.

DIY Fuel Injector Tester

at 6:40 pm. Filed under Cool Gadgets, Electronic Hacks


Fuel injectors are in all modern vehicles but you have probably not played with one since it is not a common replacement item. Jeremy Lang demonstrates his Fuel Injector Test system and shows off how an injector works. If you are interested in building your own Jeremy has made the build details available here

Arduino Mega based Speedometer and Tachometer

at 5:09 pm. Filed under Electronic Hacks


Gravi Capa is building a great looking Arduino Mega based speedometer and tachometer. It is still a work in progress and hopefully Gravi shares all the build details when he is complete. You can see the display performing a self test above and a rev test below when he tied it into his Honda motorcycle. The LED based display should look great in all lighting conditions!

DIY Animatronic Puppet Head

at 4:47 pm. Filed under DIY Hacks, Electronic Hacks


The Ben Heck Show has a cool DIY Animatronic Puppet Head project. This project listens for speech and moves the puppet mouth accordingly.

 “In this episode Ben sets out to help Backflip films with their upcoming puppet movie The Princess Knight. The film requires its actors to memorize prerecorded dialogue in order to match it with the mouth of a puppet. In this episode Ben sets out to create an animatronic head that would move its mouth automatically by detecting the highs and lows of audio waveform.”

Make a Emergency Phone Charger from a Pencil

at 9:16 pm. Filed under Cool Gadgets, Electronic Hacks


Language Warning on this video by AvE. If some swear words turn you off this video isn’t for you. This is the type of project that could come in handy when you find yourself stuck in the bush with no stores in site. We are shown how to use the resistive properties of the pencil lead to act as a voltage divider and drop the voltage to a save level for phone charging. It would be better to connect it to a 5 volt USB charge cable if one was handy since this will most likely have some voltage protection circuitry built into it, the cable could be cut and stripped with the knife in your back pocket.  That way if you are connected into the USB side of things you could slowly increase the voltage till the phone turns on and starts charging. The only thing to look out for would be the thing you are using as your voltage divider, if it has low resistance it might heat up and burn you.

Alarm Clock that Opens Window Blinds

 Alarm Clock that Opens Window Blinds


If you are a heavy sleeper you might need an Alarm Clock that Opens Window Blinds. What better way to wake up than some rays of sun shine, this is assuming that you are trying to wake up in the morning when the sun is out. If you are a shift worker this might not work very well for you.

“It is created using a Spark Core micro controller, a H-Drive circuit, and a really strong geared motor. Its cheap, simple to use, and pretty easy to make! Essentially this project allows your blinds to open and let the sunlight in to wake you up in the morning instead of waking up to that annoying alarm we all have.”

RC Car GPS Follower

at 8:55 pm. Filed under DIY Hacks, Electronic Hacks


If you have some RC gear and a few bits of GPS electronics this project that iforce2d built might be worth a look.  Have a look at it in action at 2:40.  The user has a GPS module and the car has a GPS module, the module with the person sends its position to the car and the car goes to that location, issue with GPS is that it isn’t very precise so following tight corners is quite challenging. This would perform great in a field though, I would like to see this connected to some farm equipment in the field. There is some code here that will help you build your own.
