Best Five Raspberry Pi Zero Electronics Projects Which Make The Most Of Its Tiny Measurement

The Raspberry Pi is definitely the hobbyist option for Build-it-yourself electronic projects. The Raspberry Pi Zero, that’s around the measurements of a stick of chewing gum, is comparatively low priced and has it’s own special use examples though. There are ten of our most liked projects which make the most of its measurement.

1. Cram a Raspberry Pi Zero Into an Old-fashioned Game Controller

It is well known the Raspberry Pi makes an nice DIY computer game console. The setup process merely demands a matter of minutes, and the Raspberry Pi Zero is utterly efficient at coping with older computer games from the SNES age and perhaps earlier. The complete project is far better when the whole system is inside a controller.

Working example (ahem), this project utilizes a SNES controller, this one tackles the NES controller, and this one uses that good old original Xbox controller. However you intend to practice it, you will have a really slick little DIY classic video game console you can easily carry around wherever.

2. Build a Tiny Dongle Computer

While the Pi Zero makes a nice little computer as it is, it makes an even better dongle computer. By doing so, you can attach it to some other computer you have, then it will tether itself directly so you won’t need to include a USB or any networking.

The most wonderful thing of this project is the point you no longer need yet another PC mouse, display screen, or keyboard hanging out around. Simply just jam in into your standard desktop PC and you are fine.

3. Build the Planet’s Minutest (Potentially) MAME Cabinet

MAME cabinets are brilliant, but they are tremendous. For the complete opposite approach, you can make use of a Raspberry Pi Zero to make one that is almost as tiny as the Pi itself.

You may need a few items to build this sucker work, for example a 3D printed case, but in the end cabinet is extremely functional, which means you’ll have the best desk add-on in the office.

4. Make a Motion Sensing Digicam

The Raspberry Pi has been a top quality motion sensing camera, but the low profile of the Pi Zero makes it even better.

Employing the Raspberry Pi Zero, your motion sensing camera has a smaller foot print, indicating it can go in even tighter rooms. To illustrate, this one mounts to your window with a pair of suction cups, which is nearly as lightweight as it can get.

5. Play Any Simpsons Episode (or perhaps Any Television Program) At Random

If you have ditched cable and gone full streaming with your media, you might still miss the days of catching a random episode of your most enjoyable show on TV. The Raspberry Pi Zero can bring that back.

In this project, they use episodes of The Simpsons stored on an Sdcard. With a custom script, you possibly can press a button and it plays an episode arbitrarily. You may increase any media you’d like here, including several shows if you wanted, however, The Simpsons are a wonderful option.

Internet of Things PCB considerations for Startups

Considering the fact that IoT appliances are so new, you would assume that getting an IoT printed circuit board (PCB) project off the ground starts by reinventing the wheel and suffering from a great deal of technical complications. This is far from the truth.
However it doesn’t imply IoT startups have a apparent path to stardom. Facing them is a number of design and manufacturing concerns which are unique to these small products. These things to consider need to be taken into consideration for the new IoT device to be successful.

On the plus side, it’s a consideration for IoT startups to know that the basic foundation for a successful cool product exists. What this means is experience and knowledge concerning the design, fabrication and assembly of these cutting-edge products are obtainable. Also, the best advice is for prudent IoT product business people and forerunners to follow the recommendations that skilled electronics manufacturing services or EMS companies provide. These companies and also their engineering employees have already completed this work with groundbreaking IoT corporations in Silicon Valley participating in the first stages of this rising industry.

The PCB of an IoT device is a special beast than the traditional one, which is much larger and flat. IoT devices, in comparison, are made up generally of either rigid-flex or flex circuit assemblies, which come with their own categories of design layout, fabrication and assembly things to consider and intricacies.

Layout

A top thing to consider is to search for skilled designers who have undertaken quite a lot of rigid-flex PCB designs. PCB space for an IoT device is tight. So you want the designer to have firsthand layout practical experience to correctly design key elements on that small space.

Besides that, most IoT gadgets are not stationary; they incur substantial movement and folding. Right here, the skilled designer plays a key role in working out bend ratios and lifecycle iterations as a important part of a design. Additional key design layout things to consider comprise signal trace thickness, number of rigid and flex circuit layers, copper weight and stiffener placement. Stiffeners are used on flex circuits to be certain that elements mounted on the flex circuit stay tightly in place to stop movement.

One additional aspect to consider is through-hole element placement in rigid-flex circuits. What makes that significant? A great deal of IoT devices are based on surface mount device placement. However , there can be through-hole elements, which are typically attached to either the rigid section or the flex portion of the board. Through-hole elements are in general useful to communicate input/output or I/O signals to the outer world. Like that, those signals can show up having an LCD or LED monitor. Through-hole element placement is a crucial thing to consider in an IoT device since when utilized on the flex part of the board, proper stiffeners ought to be designed and employed for appropriate assembly.

Then finally in the layout category, the high temperature that elements deliver is required to be deemed. IoT gadgets are increasingly challenging with rigid-flex and flex circuits featuring up to 12 to 14 layers. Several gadgets are digital. However , increasingly more analog systems are being utilized in IoT systems. Analog circuitry makes far more heat than digital ones. This suggests heat expansion and contraction rate should be considered. In tech lingo, it is known as the Coefficient of Thermal Expansion or CTE and the proper treatments for it.

Fabrication

Selecting the best fabricator is important and is linked to the EMS firm you have chosen. The fabricator you expect needs to have IoT PCB fabrication experience. Among key things to consider here are making sure robust adhesions in between layers on both rigid and flex circuit sides, understanding all the essential calculations and possessing a strong comprehension of when current moves from the rigid side to the flex side.

These fabricators also must get an in-depth know-how about tremendously tiny parts for instance 0201 and also 00105 device packages, package-on-package, and the use of fine-pitch ball-grid array or BGA packaged devices.

They also need to have knowledge of designing boards with fairly tight tolerances in terms of footprint for those types of BGA devices, in terms of up-to-date capabilities like laser direct imaging for putting the solder mask on the board. They need to have laser drills for via drilling with sizes of 5 mils or under since these IoT products could be so tiny that a common drill size of 5 to 8 mils may well not be all you need. They may require to go to a 3 mil, which means that you have to have an cutting-edge laser drilling capability on-site.

If you’re placing via-in-pad, it’s a easy way to take advantage of the small land which is available on the rigid-flex board, nevertheless , it produces difficulties for assembly. If vias are not fully planar or flat in shape, it will be hard through the assembly of those tiny BGA packaged devices. That’s because non-planar surfaces may threaten the integrity of solder joints.

At times via in pads leave bumps in cases where they’re not scoured properly after positioning the vias and gold finish at the top. When there are bumps, then the solder joints in the assembly for those tiny BGA balls in those IoT devices wouldn’t be an excellent joint. It could create spotty connections, which can be a larger issue to treat and remedy. It all boils down to which EMS firm you are using because they’re the ones who will pick the fabrication facility to make a successful IoT product for you.

PCB Assembly

It’s crucial to head off to skilled EMS companies that have effectively assembled IoT and wearable PCBs since they have specialized tooling and fixtures readily obtainable, which are essential for assembly to make sure components are placed appropriately, precisely and the printing is completed effectively.

Printing can be a problem for IoT systems. If it’s a rigid-flex board, then you can find a difference between thicknesses of the rigid and flex circuit portions, which means a special fixture is required to retain the complete rigid-flex board planar or absolutely flat to allow effective printing to be carried out.

Startups should be all set to choose the correct manufacturing partners and EMS companies. In this manner they can make sure they’ve ample experience upfront to get the multitude of design, fabrication and assembly details effectively performed since they are essential to a triumphant and timely IoT product release.

On the plus side, it’s essential for IoT startups to recognise that the basic foundation for a successful cool product exists. This indicates experience and knowledge regarding the design, fabrication and assembly of such innovative products are existing. Also, the best advice is for heady IoT product enterprisers and innovators to look closely at the counsel that experienced electronics manufacturing services or EMS vendors have to give you. These businesses along with their engineering team members have previously implemented the task with revolutionary IoT businesses in Silicon Valley joining the beginning of this surfacing market.

The PCB of an IoT device is a different beast than the traditional one, which is considerably larger and flat. IoT units, on the flip side, comprise mainly of either rigid-flex or flex circuit assemblies, which come with their own groups of design layout, fabrication and assembly considerations and nuances.

Layout

A key concern is to seek out veteran designers who have accomplished many rigid-flex PCB designs. PCB space for an IoT device is confined. So you want the designer to have directly layout experience to correctly design crucial parts on that little space.

Additionally, nearly all IoT gadgets aren’t stationary; they get significant movement and folding. Right here, the veteran designer plays an important role in determining bend ratios and lifecycle iterations as a critical part of a design. Additional crucial design layout considerations incorporate signal trace thickness, number of rigid and flex circuit layers, copper weight and stiffener placement.

Through-hole parts are generally employed to communicate input/output or I/O signals to the outer world. Doing this, those signals can show up utilising an LCD or LED monitor. Through-hole element placement is a critical account in an IoT system as when applied on the flex area of the board, suitable stiffeners must be designed and employed for excellent assembly.

Lastly in the layout category, the heat that parts deliver ought to be deemed. IoT gadgets are ever more challenging with rigid-flex and flex circuits featuring over 12 – 14 layers. A few gadgets are digital. Nevertheless , increasingly more analog products are getting used in IoT products. Analog circuitry generates considerably more heat than digital ones. It implies heat expansion and then contraction rate are required to be thought about. In tech lingo, this is actually referred to as the Coefficient of Thermal Expansion or CTE and the right control over it.

Fabrication

Choosing the proper fabricator is very important and is linked to the EMS corporation you’ve picked. The fabricator you want should have IoT PCB fabrication practical experience. Amongst crucial considerations here are insuring strong adhesions between layers on both rigid and flex circuit sides, realizing all the crucial calculations and obtaining a strong comprehension of when current moves from the rigid side to the flex side.

Such fabricators also need to get an in-depth knowledge of very miniature parts similar to 0201 and 00105 device packages, package-on-package, and the use of fine-pitch ball-grid array or BGA packaged devices.

Additionally they must have experience of designing boards with extremely tight tolerances in terms of footprint for those sorts of BGA devices, in terms of up-to-date capabilities like laser direct imaging for putting the solder mask on the board. They ought to have laser drills for via drilling with sizes of 5 mils or under as these IoT products could be so compact that a standard drill size of 5 to 8 mils probably won’t be enough.

If you’re placing via-in-pad, it’s a great way to make use of the small land which is available on the rigid-flex board, however , it presents trouble for assembly. If vias aren’t entirely planar or flat in shape, it could be tricky throughout the assembly of those tiny BGA packaged devices. That is because non-planar surfaces might put in danger the integrity of solder joints.

At times via in pads leave bumps in the event they’re not scrubbed appropriately after positioning the vias and gold finish on the top. When there are bumps, then the solder joints in the assembly for those tiny BGA balls in those IoT devices would not be an ideal joint. It may create irregular connections, which might be a larger issue to handle and repair. It all boils down to which EMS corporation you’re working with because they’re the ones who will pick the fabrication house to make a successful IoT device for you.

PCB Assembly

It’s very important to take a look at veteran EMS companies that have efficiently assembled IoT and wearable PCBs because they have unique tooling and fixtures already existing, which are important for assembly to make sure components are placed the proper way, accurately and the printing is made in the right way.

Printing generally is a problem for IoT products. If it’s a rigid-flex board, then you will find there’s a change between thicknesses of the rigid and flex circuit portions, that means a special fixture is required to retain the complete rigid-flex board planar or absolutely flat to get effective printing to become executed.

Startups ought to be geared up to choose the proper manufacturing partners and EMS companies. This way they can make sure they have adequate experience beforehand to get the multitude of design, fabrication and assembly details successfully performed since they are crucial to a triumphant and timely IoT product release.

3. Create your personal Raspberry Pi-powered R2-D2

For those who have always wanted to hack a toy R2-D2 into something a little bit more practical, the Raspberry Pi Zero W has arrived to oblige. Les Pounder at TechRadar has published a tutorial for adding some wheels and attitude to the favorite robot from the “Star Wars” world.

Check out the step-by-step instructions listed here. http://www.techradar.com/how-to/computing/how-to-build-your-own-r2-d2-with-the-raspberry-pi-zero-1310979

4. A Pi Zero W wireless security camera

One of the many great obvious benefits to using a Raspberry Pi Zero W is being able to remain connected to the online world in places lacking ethernet connection. For wireless security camera products, this new supplement is rather helpful.

PCB solder pad repair & corrosion clean up – The epoxy method



This is a demonstration of a PCB repair which involves repairing damaged surface mount solder pads as well as cleaning up corrosion from a leaking electrolytic capacitor. The pads had been damaged by the owner of the motherboard as a result of him trying to repair the board on his own.

I hope that this video will give you some ideas on how to perform a proper pad repair using the epoxy method.
During this repair, I used an epoxy that is heat resistant up to 315°C for 60 seconds.
If you ever find any kind of epoxy on the market that is specified to be heat resistant up to more than 315°C, then I would be happy if you could let us know about it in the comment section as it does appear that high temperature epoxies are quite difficult to find.

The following products was used in this video:
CircuitWorks CW2500 – Two component epoxy overcoat
CircuitWorks CW3300 – Overcoat Pen

I have made several videos before where I have had to fix up other people’s mistakes that they have made during their repair attempts, and this repair only adds on to the list.
If you are not a repair technician and your motherboard has stopped working, it would be in the best of your own interest not to attempt a repair that you really cannot handle. Because there is a huge risk that you will actually end up doing more harm than good. We are of course mostly talking about board damage in the case of motherboards, but it gets considerably worse when dealing with things like power supplies, which can easily become a great shock hazard to inexperienced technicians and even result in electrocution.

As always, comments and questions regarding this repair are always welcome.

$9 CHIP Computer Review – Does the C.H.I.P Kickstarter Deliver?



So what can a $9 computer do? The answer for the C.H.I.P. computer is not much unfortunately – unless you’re a maker looking for a decent microcontroller backed by a full Linux Operating system. See more cheap computers: http://lon.tv/sbc and subscribe! http://lon.tv/s

Find the keyboard / trackpad combo here: http://lon.tv/keytrack (Amazon affiliate link)

For $9 the C.H.I.P. makers deliver an out of the box bootable computer. It has Wifi, bluetooth, 4 GB of flash storage, 512 MB of RAM and a really slow single core Allwiner R8 processor. The $9 configuration comes only with 480p composite video.

To add HD resolution requires the purchase of a $15 HDMI card called the Dip. A VGA version is available for $10.

While this computer is only $9, it’s pretty much useless as a desktop computer. Web browsing is horribly slow. Game emulation, even for old 8 bit games, is a non-starter. And media playback is also not really possible on it.

What’s it good for then? Coding for one. The device has a full installation of Debian Linux installed with plenty of coding options available. There’s a “headless” version for it to operate in console only mode, with plenty of hardware connections for sensors and other devices.

Consumers may be more interested in the $49 Pocket CHIP configuration that comes with a handheld touch display, keyboard, and battery. The reason is that the software is better optimized for the limited hardware in that device. But there’s very little to do on it.

In many ways this product represents the problem with Kickstarter. At the time it was announced over a year ago a $9 computer was easily the least expensive thing out there. Just a few weeks after the announcement Raspberry Pi SHIPPED a $5 computer that performs better than this one that’s first being released in 2016.

This computer does have some utility for makers but not consumers looking for a cheap computer to play with. My advice is to spend a little bit more and look at the Raspberry Pi 3.

One-upping the NES Classic Edition with the Raspberry Pi 3 and RetroPie

NES Classic is no more, but luckily economical hobbyist boards are great for little projects.

Last Nov., Nintendo shocked everyone by going back to its root base and releasing the NES Classic. The pleasing emulator/nostalgia-fest started unexpected demand, including near-instant supply issues and 200-percent-plus markups in secondary markets. So in December of 2016, we made a decision to build our own version instead. Since Nintendo bizarrely announced that it won’t be making any more of the hard-to-find mini consoles recently, we’re re-running this piece to help people with a DIY streak again build your own. Hardware recommendations have been updated to reflect current availability and pricing for April 2017.

CHIP Computer Project: CPU Temperature Monitor with OLED display SSD1306



Today we are going to connect an OLED display to the chip computer (often called the $9 computer) in order to monitor its CPU temperature in real time. Let’s start!

Full disclosure: Some of the links above are affiliate links. I get a small percentage of each sale they generate. Thank you for your support!

Today’s project is this: I have connected an I2C OLED display to the CHIP single board computer and I print the temperature of the CPU on it in real time! It is a very easy project to build and it can be easily ported to support the Raspberry Pi as well. Let’s see how to build this project.

I received the CHIP single board computer about a year ago. It is an impressive board, it costs $9 and it offers a 1GHz CPU, 256MB of RAM wifi Bluetooth and many more things. You can watch my review of the CHIP computer by clicking on the card here. As you can see the CHIP computer is a lot smaller than the Raspberry Pi 3 board and of course it costs a lot less. One year later, the software developed for the CHIP computer is mature and we can easily build some projects with it.

For this project we also use this small monochrome OLED display. It is one of my favorite displays because it is very easy to use since it use the I2C interface which only needs to connect two wires. The cost of this display is around $6. You can find links for both parts in the description of the video.

In order to connect the OLED display to the CHIP computer we only have to connect 4 wires. The GND pin of the display goes GND, Vcc goes to the 3.3V output of the display, SCL pin of the display goes to the SCK pin of the CHIP computer and lastly the SDA pin of the display goes to the SDA pin of the CHIP computer. It is very nice to have the pins labeled on the CHIP computer isn’t it? It makes things easier. Maybe the Raspberry Pi needs to follow the same tactic with their boards. Now, let’s move on the software side of the project.
