Introducing the *new* Ti-84 Evo. And perhaps I more accurately mean "new." Who I am kidding, we're dealing with Texas Instruments Education; there will never be a truly new.


From mr womp womp on Cemetech:
Here's what we know so far:

- It is the successor to the TI-84 Plus CE Python, and as such, we can expect all the same features software-wise (Graphing, Flash Apps, TI-Basic, Python, etc.) It is yet to be confirmed whether flash apps will be included as an indiscrete part of the OS like the TI-82AEP or if they will continue to be standalone apps.

- Like the TI-84PCE, it will have a rechargeable li-ion battery and color 240x320 TFT LCD.

- It will feature a brand-new ASIC. According to the listing, this processor is said to be "3x faster", which would imply 144 MHz equivalent... more than standard eZ80 implementations. Maybe this will be an ARM processor that both emulates the ez80 and runs the Python interpreter on a single ASIC ?

- It will likely have a USB Type-C port

- It is said to have ”50% more graphing space”, which certainly means they removed the arbitrary border around the graphing area.

- It will feature an Icon-based home screen

The key layout seems to have changed in a few significant ways, which provide clues about calculator functionality:

- Firstly the ON key now features a home icon to go back to the home screen, which is no longer the “calculator” app.

- The X^^-1 key and ^ keys have been merged into a single X^n key, making way for the new <> key. The TI-83 Premium CE has always had this key, which is used to switch between exact and approx answers. This seems to suggest that the Evo could have an exact math engine like the TI-83 Premium CE.

- The APPS key has been replaced with a MathPrint fraction, which had previously been relegated to a 2nd function since OS 5.3.0. The home button will serve a double purpose as an APPS key.
Interestingly, the MODE button has not been removed despite the home screen containing a gear icon. Perhaps these will both lead to the same menu, or there will be a new “settings” menu, distinct from the MODE menu.

While the overall shape of the calculator appears to be the same as the TI-84 Plus CE, it lacks the iconic screen bezel, which means the case plastics have been completely redesigned. Hopefully the new design will fit seamlessly into old TI-84 Plus CE Docking Stations and the slidecases will be interchangeable.

The TI-84 Evo, like its predecessors, is approved for standardized exams, including the ACT®, SAT®, IB®, and AP® courses.

All hail the great calculator empire!
And some good news to report.

Last Friday both my DM15c from Swiss Micros and a Nagoya 16 inch whip VHF/UHF antenna were delivered to my home. The calculator, as noted in my earlier post, was meant to be a Christmas present and was ordered from Switzerland weeks before, but was held up somewhere with Canada Post and came about 2/3rds in January.

The antenna is a highly suggested addition to my Baofeng 5RM handheld radio that I have been using to get familiar with traffic and repeaters in my local area. The antenna itself is wonderful and works very well. Now I am slowly working on my amateur radio license so that I can engage in some of the interesting nets that happen regularly. So far I've been tracking a Canada-wide net that takes place across a series of repeaters every weekday morning at 8 am in addition to a local net with repeaters all across the island. These nets are great because people give a short blurb about what they are up to for the day or what the weather is like where they are which is particularly interesting, even just to listen to. Another one that I've found and have enjoyed being around to listen to each evening is the Insomnia Net which takes place on a network spanning the whole continent called the WIN system. They do trivia starting at 10pm every single day of the year and people from all around Canada and mostly the United States check in and share answers. There are regulars that are fun to listen to and wait for checking in and newcomers every night. I can't wait to be a newcomer myself and check in whenever I am available.

The calculator is truly wonderful. It is a credit card sized version of the hugely popular HP15C RPN advanced-scientific calculator. It is not as thin as a credit card, you cannot fit it into a wallet and no would you want to really. The height and width of the device is credit card sized, roughly the width of the LCD screen from the original device. It has very nice upgrades include a new, much faster processor that emulates the old NUT processor of the HP device. You can also choose two different speeds for this processor to extend battery life when not doing intensive calculations. The LCD screen is a very large and clear dot-matrix display which several font options designed by the Swiss Micros team.

Even more wonderful is a two-line display option that shows two of the four RPN stack registers on the display at all times. This is great because you can see the two figures being manipulated by an operand and I like to use the two-lines for answers that programs produce to provide more context. For example, for my g-force braking program, the user can input speed in km/h and the desire g-force experienced by passengers and the program produces the time in seconds for the brake event in the y-register and the braking event distance in m in the x-register. Both items are useful for learning and planning and both can be displayed upfront and clearly in a two-line display.

The calculator also has a library of units for conversions and common constants used across several scientific disciplines. This is an exceedingly nice feature packed into such a small device. Which brings me to the whole point. I already own a DM32 RPN calculator that has an even more beautiful and large four-line display and a way more processor with way more precision for intense mathematical calculations in the palm of one's hand. But the DM32 is not really meant for the field, not for me at least. It it a home device or an office device but not an in the bus, on the road, out and about kind of device. But the very small DM15c is such a device. The perfect everyday carry that packs a very powerful punch.

And that's all about that I have by way of good news for the moment.

So get this, the Baofeng radio that I wrote about in my previous post has not shown up. When I call the shipping company, they have a wait time of three hours plus. And I do not have three hours to wait for customer service on the weekdays when they are open. But I ordered another Baofeng radio model on Amazon and it came right to my door in two days! And also since that time Canada Post has delivered my Swiss Micros DM15C-- a credit card sized version of the famous HP15C RPN calculator.

And so just just like the title says, the beat goes on, because I at least have a handheld radio (a pretty fine one for the low, low price) and my precious credit card sized DM15C which is henceforth my everyday carry.


...and the beat goes on and on and on.

The title is going to be a little melodramatic, but I do not care. I am upset right now and I am going to share why here.

The reality is that right now I am supposed to be tinkering with both a DM15c calculator from Swiss Micros and a Baofeng handheld radio. Both were ordered for Christmas. The calculator was ordered well before Christmas by my partner. The radio was ordered on Boxing Day with some cash that I got from a family member.

Both items originated outside of my home country of Canada; Switzerland for the calculator, mainland China for the radio. Both items snakes through their origin countries with ease. It took a day and a half for the radio to move from an in-land warehouse in China, to an airport on the coast, to Hong Kong and finally to Vancouver, Canada to meet Canadian customs. The calculator took a little longer, about five years to snake through Europe and eventually land in Toronto, Canada. And this is where the case of each item diverges.

The calculator ends up in Canada about 14 days before Christmas. I live on the west coast so not close to Toronto, items shipping from my family in Ontario typically take a week by Canada Post. The calculator however just switched to a status from in customs to in transit yesterday. Yesterday! The Europeans can get the device to move through their entire continent in a handful of days, but it takes weeks upon weeks to move within Canada.

The radio is even more egregious. It lands in Vancouver which is very close to where I live. Things typically in Vancouver take a day to ship to my home on Vancouver Island. However, the radio company uses a last-mile shipper and in my case this is a terrible company named Firefly which used to be known as Intercom. A quick search online reveals hundreds of reviews of people losing their packages, having them damaged or destroyed or in one case several customers getting the same proof of delivery imagine (indicating a potential fraud where packages are being stolen in the system). I have no control over who delivers the radio. So what happens with mine? It gets delivered in a reasonable time, according to the tracker within two days of landing in Vancouver it is in a delivery van en route to my location. SanderheepA. is the driver who leaves my package under a drain pipe during rainy season (according to the super grainy and blurred photo I was sent in my email) to a home that isn't mine. And surprise, surprise isn't any home on my short little road in my neighbourhood. I do not know where SanderheepA. has delivered by package but it is nowhere near my home.

So I call customer service. It is a three hour wait to talk to someone. When I first found out about the bunk delivery I was at work and was not finishing my shift until 8 pm (when their customer service offices are closed). Same for the next day. I try on breaks but because of the long wait time I get no further than listening to broken elevator music while being reminded every few minutes that the service representatives will not tolerate any abuse (because when you're running a theft scam, you're going to have a lot of upset people). At any rate, got in touch with them this morning. And know what I was told? Sorry nothing can be done three days have passed and because I did not call within that window it is no longer their responsibility. I now have to contact the seller (a company in China!) and try and get a refund.

So that is the state of my country. China and Europe can move items within their borders in a reasonable amount of time. A basic requirement one might assume for a developed nation. Canada on the other hand cannot. We either have to deal with inefficient government services like customers or very poor state-run postal delivery services like Canada Post. Or, and this is what really burns me, we have scam companies like Firefly starting up that are designed to fraud people. Because we do not have an efficient and effective government (slowly more and more resembling the very countries people like SanderheepA. have left) we cannot stop these things from happen or people from being scammed by them. It is a shame.

So now I do not have either Christmas present that I supposed to get. And even though the items are international and you might assume oh they must be taking a while to get here, no they are here, it is my own country, my supposed own people who cannot move small packages within our own borders. That is sad. And since I do not have the calculator or the radio I will just sit here and stew.

I have a resolution to write more in my own little space. And so this is the start of that.

Not much has really changed my way. I continue to explore the SwissMicros and Texas Instruments calculators. I am currently waiting on a DM15c which is a credit card sized remake of the very popular HP15c. This will add to my current SM "collection," a DM32 that apparently has been feeling lonely.

I am also working on porting an RPN calculator app that was made for the monochrome Ti-83 and Ti-84 Plus calculators but not for the new Ti-84 Plus CE which had a back-lit colour LCD screen. The processor is also different being an upgrade from the old but super reliable z80 (now it is called the ez80). So this is going to be a lot of work but the original creator who has given me their blessing to port, has done a lot of the heavy lifting by way of a logic, I just need to focus on what changes with the new processor and LCD (among other things but those are the biggest).

And lastly I finally pulled the trigger and ordered a Baofeng handheld radio. These are all of the rage in the HAM radio community because of their versatility and price. They have also gained a lot of haters as a result. The model that I purchased is only capable of transmitting on GMRS but can receive on a host of popular channels including FM radio, air traffic control, popular HAM bands and marine channels-- including my beloved NOAA/Environment Canada weather stations. It is technically not a legal radio in Canada and is not certified for use by Industry Canada (the folks who oversee the radio spectrum and licensing in Canada). GMRS does not require any licensing at all, it is the band used by cheap blister pack radios that families and campers purchase for personal use. But unlike the US, in Canada GMRS radios must have a fixed antenna and cannot transmit over (I think) 1 watt. The model I am waiting on can transmit at 5W. It was made for the US where GMRS is popular for enthusiasts where a licence can be obtained online that covers a whole family and the extra power and better hardware means you can get some good range out of it. But this is not the case in Canada.

So why purchase it? Well first I am at the point in my HAM radio journey that I really only enjoy listening and learning about how things work and what the community actually does on the air. I am also interested in having the weather stations and air traffic control for amusement. I also won't have any issue using GMRS with friends despite the fact the radio is not certified for use. I doubt up island, in the bush anyone is going to care, especially if I am not bothering anyone of any consequence. This is a big reason why these Baofeng radios have been getting some heat from so-called sad-HAMs who are users that are extremely strict about the rules. Fair enough.

Like one of my favourite cartoon characters once said: there's the truth and there's the truth.
