![]() ![]() The orange to green silica gel was offered and this then underwent a scrutinising process and trial, and it performed extremely satisfactorily for the customer. Not good!Īt that stage, one of the other alternatives were offered and by this stage as you can appreciate, the trust had been somewhat damaged through supplying the previous ‘unacceptable’ product. He was not happy with the style of colour change…from orange to a translucent white and he thought it might have even been affected by the UV rays. The customer was absolutely clear that blue to pink was unacceptable to them, and so an alternative was offered: the orange to white silica gel.Ībout twelve weeks into the trial of the new product a very irate substation maintainer phoned up and complained about the new orange to white gel discolouring after only three months in the field. The initial response was …Certainly! We can supply you silica gel…it will be the blue to pink style. Some years ago, another large Power company had a difficulty in their supply chain for silica gel so they approached an alternative supplier, who stocked silica gel. The decision would have been somewhat based on the fact that the orange to green silica gel, also known as e-Gel, is more environmentally friendly, and is non-cobalt based, therefore the product is classed as non-carcinogenic. However, since that time that same organisation has migrated to using the non-cobalt based silica gel – and they have started to use the orange to green silica gel, which has the methyl violet as the indicator. One large organisation conducted extensive tests and the final report that was presented gave them peace of mind that it was still OK to use the blue to pink silica gel, in that while the cobalt chloride was present, the parts per million (ppm) was such a low number that they felt it was safe enough to continue using the conventional blue to pink silica gel. Here is a rough guide of three of the well-known indicating silica gels on the market and the typical indicator that is used in each version: COLOUR RANGEĬertain organisations have done testing as to the safety of such products. It is the indicator that determines what the start and end colours will be. What is all this about silica gel and carcinogenic and cobalt blue and non-cobalt?įirst thing to say is that Silica Gel is SiO2 and whether it has blue-to-pink or orange-to-white or orange-to-green indicating properties, the base product is still SiO2, silicon dioxide. ![]()

This puts LCD in highest contrast and read mode. The contrast bit and READ/WRITE are not often used so they can be shorted to ground. In the circuit, you can observe I have only took two control pins, this gives the flexibility. Now in the 14 pins there are 8 data pins (7-14 or D0-D7), 2 power supply pins (1&2 or VSS&VDD or GND&+5v), 3 rd pin for contrast control (VEE-controls how thick the characters should be shown), and 3 control pins (RS&RW&E). One can power or leave the back light pins. In 16x2 LCD there are 16 pins over all if there is a back light, if there is no back light there will be 14 pins. Hardware: ARDUINO UNO, power supply (5v), JHD_162ALCD(16x2LCD), 100uF capacitor. This tutorial provides Step-by-step guide, Circuit Diagram, and Complete code to learn how to Interface 16x2 LCD with Arduino You can follow the below link for an updated tutorial. Note: We updated this tutorial and added some more additional information along with a step-by-step guide to interface 16x2 LCD with Arduino. We just have to define the pin numbers and it will be ready to display data on LCD. Here we don’t have to worry about data sending and receiving. Unlike normal development boards interfacing an LCD to an ARDUINO is quite easy. In this tutorial, we are going to interface a 16x2 LCD with ARDUINO UNO. (you can see it in LCD unit, it is the black eye at the back ). But we need not to worry about that because there is another controller (HD44780) in the display unit which does the job of controlling the pixels. Here one must understand that in each character there are 5x10=50 pixels so to display one character all 50 pixels must work together. The 16x2 LCD will have 32 characters in total 16in 1 st line and another 16 in 2 nd line. The 16x1 display unit will have 16 characters and are in one line. Besides complex display units like graphic displays and 3D dispays, one must know working with simple displays like 16x1 and 16x2 units. And so they are an important part of embedded systems. Display units - big or small, work on the same basic principle. To establish a good communication between human world and machine world, display units play an important role. ![]() ![]() ![]() To learn more about how and for what purposes Amazon uses personal information (such as Amazon Store order history), please visit our Privacy Notice.

ZenMate is one of the only VPNs on the market with encryption on its browser extensions - ZenMate’s support representatives confirmed that the browser extensions use 128-bit AES encryption, which provides excellent security. And RAM-only servers never store any data on a hard drive and every server reset wipes all of the data. Perfect forward secrecy changes your encryption key for each session so that hackers can’t compromise past or future sessions. I ran leak tests on 10+ servers and thankfully never saw any leaks.Īnd I like that ZenMate has perfect forward secrecy and RAM-only servers. I’m a big fan of how ZenMate comes with full protection against IPv6, DNS, and WebRTC leaks (some top VPNs like VyprVPN don’t have IPv6 and WebRTC protection and you need to manually disable them). ![]() I’d really like to see ZenMate VPN add WireGuard to its other apps in the future. ZenMate comes with OpenVPN, IKEv2/IPSec, and WireGuard. While WireGuard is faster than IKEv2/IPSec and OpenVPN, it’s only available on ZenMate’s Android app - top competitors like Private Internet Access and ProtonVPN have WireGuard on all of their apps. Kill switch - This feature disconnects you from the internet if your VPN connection drops to prevent traffic leaks. ![]() No-logs policy - ZenMate VPN doesn’t log your IP address and internet traffic (sites you visit and files you download).256-bit AES encryption - ZenMate VPN protects your data with military-grade encryption.ZenMate VPN has the following industry-standard security features: And it has P2P servers in 50+ countries, provides fast download speeds, and works with popular torrenting apps.Īnd while I’m not a fan of how ZenMate VPN includes split-tunneling and malware blocking only in its browser extensions, it provides excellent security features, allows unlimited connections, and maintains fast speeds on all servers. ZenMate is able to access 30+ streaming sites via dedicated streaming servers in 10+ countries (and its regular servers also work with top sites like Netflix). And there is no doubt that ZenMate is good for streaming and torrenting. I spent a few weeks researching and testing ZenMate VPN to see how it compares to other top VPNs on the market. ZenMate covers all of its plans with a 30-day money-back guarantee.ģ0 Days Risk-Free - Try ZenMate VPN Now ZenMate VPN Full Review ZenMate VPN has 2 tier-based paid subscription plans, and each one comes with monthly and yearly plans. While ZenMate is a great VPN provider, there are some annoying issues - it can’t access Hulu, extra features like split-tunneling and malware blocking are only available on its browser extensions, and live chat isn’t available 24/7. On top of industry-standard security features, ZenMate VPN also has: It also works with top streaming sites like Netflix and Amazon Prime, and it allows unlimited connections, which makes it perfect for large households. In my tests, I experienced fast speeds across all servers - websites and HD videos loaded almost instantly and I had fast torrenting speeds. ZenMate VPN is secure, fast, and user-friendly. ZenMate’s staff will still continue to handle their users’ subscriptions and provide them with customer support. There are no changes to ZenMate users’ subscriptions, but they will need to transition to CyberGhost’s apps once ZenMate’s apps are discontinued. ZenMate VPN has partnered with CyberGhost VPN, which resulted in ZenMate’s service being integrated into CyberGhost. ![]() ![]() ![]() Tiffin could have installed a small shelf unit to add more storage space. There isn’t enough storage, so we’ve improvised by placing a wire stand to store more items. It sucks up quite a lot of energy when you’re boondocking, for instance.Īnd although the bathroom is roomy, there’s actually a lot of wasted space. The large, residential-size fridge is both a pro and a con. It is huge and convenient, but sucks up a lot of battery power. One of the pros can be a con in a boondocking situation (camping without electrical, water and sewer hookups): the residential fridge. It’s difficult to find fault with our rig, but there are a few quirks. Tiffin Allegro: The Cons Wasted Space & Energy You can read about my husband’s first time driving the coach here. But our Allegro was built on a longer chassis with a foil cushion, making for a pretty smooth drive. Typically, diesel coaches are more powerful than gas coaches, which can make for smoother driving. It’s a dream come true!Īnd the ceiling fan in the bedroom actually does lower the temperature - it wasn’t just a “decorative” fan. ![]() Imagine sipping hot coffee by the fire on a chilly morning while gazing at a misty meadow. That’s right, we even have a fireplace, which comes in handy on chilly days. There are two features that I didn’t really care about in the beginning but have come to love: the fireplace and bedroom fan. We like the fact that the layout gives us plenty of room to move around. In fact, we didn’t even learn about the storage drawers under the dinette seats until after we’d bought the coach - a happy surprise! This is a floor plan from this year’s model. The layout allows us to move around comfortably and there’s plenty of storage. The kitchen faces the door, which makes me feel safer because I can see outside while I’m cooking. While we liked it, the minute we walked into the Tiffin, everything felt sturdier - solid cupboards, comfortable sofa and supportive dinette booth seats. We had been spending time in an RV with a similar floor plan from a different brand. The quality is what sold us on our purchase. The level of quality in the Tiffin Allegro really stood out and ultimately sold us on this model over cheaper RVs. I can back that up as we’ve put about 20,000 miles on ours and it’s still holding up well. Tiffin has a reputation for making high-quality RVs. It helps that we negotiated the price down, too. Tiffin is a great company and both the length and features that came with our coach are perfect for our travel style. While it was a bit more money than we budgeted for, we feel like it was worth the investment. It’s got a big windshield, two slide outs and it comes in at 34 feet (which is a good size for camping at most state and national parks)! Click here to read more about buying an RV.)Īfter touring what felt like hundreds of RVs and almost buying a different model, we ended up with our motorhome- a Tiffin Allegro 32-SA Class A gas coach. (By the way, if you’re in the market for an RV, be sure to go into as many as you can or even rent an RV or two so that you can get a feel for different floor plans. But after traveling in it for over a year and a half, we still feel like we made a really good decision - and that the extra money really was worth it. When we bought our first RV, I nearly broke out in a full-body sweat because we had fallen in love with a model that was over our budget. Then the panic sets in because it’s really happening. Shopping for an RV is fun - until you make a decision to actually buy one. ![]() |
