A great starting step for your next uSDX SDR radio project

For uSDX SDR TRX - OLED TriBand 5 x Board Kit

Top quality PCBs, beautiful readable components mask in white color, tested continuity as an old habit of mine and all is good to go populating the boards. And the package arrived right in time as advertised, using proper packaging.
Many thanks Jason, appreciating your services.

Good radio for starters, but could use improvements.

For DSP RADIO Multi Band AM/MW/LW/SW-SSB/FM with RDS

Nice design. Would like to know about using a ferrite antenna for AM reception? I have the RF preamp, which I think is combining the AM/FM/SW to use just a single antenna. I have hooked up an outdoor antenna to get better reception. Indoors with a telescoping antenna I could barely receive anything even with the preamp. Audio from the headphone jack is very low. Adjusting the volume any higher than 50 starts distorting the audio. Using 2 18650 batteries in series would be better if provided a 3-terminal connector for balanced charging. Display could be bigger, I'll fix that. Ability to flush mount the front PCB board to a panel don't look like it would go well. Probably same for the rear unit connectors running flush on a panel. Looks like this is using the arduino library but still would like to see your source code to do some minor modifications. This is more of a test bed for me as I am planning my own design soon for use in an automobile. The cost of the unit was acceptable I have no complaints with that. Was considering getting the other unit you have with the color LCD display when I have the money to do so. A schematic of the RF preamp PCB board would be nice. Everything arrived good to the US and it was delivered fast.

Very good product !

For Classic 70's Pong Game

Very good arcade Pong simulation ! Its nearly perfect and by far one the best we may find on all over internet ! I would like to order more ;)
Best regards.

Awesome radio.

For SI4735 D60 TFT 2.8" ESP32 ALL BAND RADIO

As a novice to the world of SDR, This unit is perfect for exploring the "ether". Good construction and really nice software UI.

Just started printing out the 3D case for it and I a sure it will look just great once I have it in its case.

I am looking forward to listening in to the many transmittions out there.

The best Nano VNA Test Board you can get.

For Nano VNA Test Board Demo

I use it for educational purposes to show fellow ham's the usage of a (Nano)VNA during club meetings and courses.

The reason I bought this from Jason is because of bad experience with the Rf Demo Kit for NanoVNA boards using UFL connectors. UFL connectors aren't made for multiple insertions. This PCB uses normal SMA PCB connectors and can be used over and over again (professional specs say 500 times, but for hobby and education, they may last a lifetime).

The used components are standard, and the more difficult components (BPF and BSF), you can buy them at digikey or mouser. Our you could do like I did, de-soldered from the now un-used Rf Demo Kit I had laying around (the one with damaged UFL connectors).

Potential nice Device

For ESP32-VS1053 MP3 Player & Web - Internet Radio

I had to wait very long to get it.
No Documentation comes with it.
I had it find it somewhere in the Internet.

For the moment i am stuck to compile, there is a SD.h to include, but here is a problem to find the correct file to compile without error.
Is there somebody to help, where to find the correct SD.h File?
Would be very nice to get a helping answer.

The transport from Malta to the Czech Republic took too long

For SI4735-D60 All Band radio - ESP32- TFT -P.C.B

The shipment arrived fine. PCB and manual excellent. Communication with the seller is good. I am satisfied.

It works more or less

For 3D Printer TSL201 Filament Width Sensor

It doesn't work properly, I have not been able to make it work as described, depending on the ambient light, the measurement varies enormously, even covering the possible entrances of external light that does not come from the LED, I continue to experience these problems, the 3d pieces if you have your own 3d printer it is better to reprint them, the quality is quite poor and the tolerances and holes do not match correctly. The button on the PCB to recalibrate works normally, although I suppose it is due to the problem mentioned above. The product has left me quite dissatisfied for its price, I have paid with shipping included ($43.50) and it has taken more than two and a half months to arrive in Spain.
In the documentation it is not mentioned at any time how the assembly of the 3D printed parts should be carried out, it may not be very complicated, but it took me a long time to find the correct way, a point to improve notably.
The included 3D parts come straight off the printer, no supports or skirts removed, takes a while to remove without messing anything up and no mention of this in the documentation.

Waste of time and money (It's too expensive for something that works so bad)

Hi Ruben

The tsl201 filament width sensor is the cut down version using the sensor 64x1 line array. It is known that accuracy is not its forte. You can download the atTint85 source code and optimize it to your needs. It has been released and is in my GitHub.

The sensor works as expected and can measure the filament at the mercy of the tsl201 line array.

If you want real accuracy then go with the tsl1401cl which has a 128x1 line array - this part is obsolete from AMS and its price has gone to the skies with the limited stock that still is available.

Overall thanks for your comments and I am always open to the customer feedback and will work further on the kit to make it better.

Great little reflow oven controller

For Reflow Oven Controller Universal Board Ver 2.01

This is a nice and great build for everyone! Well built and compact format so fits in a tiny box. I used a $12 K type thermocouple since others were 4x the price. The issue with thermocouples is that they create a tiny voltage (around 40 micro volts) so they are susceptible to noise especially at the screw terminals. So I had a few go's at that to get it to work properly. Also I built in a simple pc fan to cool the toaster oven down fast. I guess adding these tips to the manual would complete this kit. I would love to get a look at the source code. Initially to fix my thermocouple issues but lucky enough no source code forced me to research. So I learned something here as well (research, research and research before hammer and duct tape approach. :) ). Well done Jason Kits.

This programmer saves me a lot of trouble!

For Portable Micro AVR Programmer

I'd been looking into making a standalone programmer for a long time but never had the time to do it. This little puppy (which I just finished as a kit) programmed my Attiny44 without a hassle. I might just 3d print a cover for this and load it with all of the code I need and ditch the laptop at the shop.
The kit was easy to build and the schematic was a nice touch. I do have to add that you need some skill when soldering surface mount parts, not that many but an important one to keep an eye on.
Just to have this programmer around saves me so much trouble to get the products tested without having a long cable or moving the laptop just to get the job done.
If you buy the kit, always remember to read the instructions, more importantly if you buy the kit without an SD card. The instructions describe each step of your file programming and how to use every function, so read it properly.
Shipping was faster than anticipated so I call that a bonus!

Don't know what I purchased

For Si5351 - 3 CHANNEL SIGNAL GENERATOR with SWEEP

In my dismay I didn't write down the exact numbers but I get square waves until I get the frequency high enough then I see a sine wave. Documentation doesn't say much at all.
Avatar
Response from JasonKits | Sept. 17, 2021
The si5351 is a programmable oscillator which produces a square wave on all three channels. If a sine wave output is required one can use an L/C/R filter to smooth the output and cut down any harmonic. With a Suitable L/C filter the output is very stable .

Dawid | June 3, 2021

Good product, works fine.

For 3DPRINTER Filament Width Sensor Kit V4

Works great.

The Kit is easy to assemble, aside from the tiny SMD capacitors. Those are tricky to solder and make it more complicated, but its doable with a little soldering experience and a set of fine tweezers.

Values for R3 and R4 in the schematic are switched. The Documentation for Version 4 shows the correct steps: R1, R2, R3 are 1k and R4 is 10k.

Reported filament width is ok and the calibration button works.

If you have issues with wrong filament width and/or calibration does not work correctly, try to use an external, stable power supply. I power the sensor via my raspberry pi and it works fine. If I power it via my SKR 2, the reported width is too small. Printer mainboards often do not put out stable 5V or do not provide enough current for the board.

If you print the case at home, print it with black filament. If the holes for the Filament are too small, take a 2 mm drill bit or small screwdriver, heat it up with a lighter and push it through the hole.

Shipping took very long, but I guess due to Corona everything gets delayed. Excellent communication with the seller.

A must have programmer

For Portable Micro AVR Programmer

Was looking for this for quite some time,and was very happy when found it here.
Got the fully assembler device.
It doesnt disappoint my expectations in any way.
I own different, non Portable, programmers, but the portability makes this a dream.
Not only does it flash AVRs, but it basically is a complete Portable device, that brings all features for working with AVRs. A Portable avr programmer, with all the functionality of avrdude in a simple, easy to use device. No other software or laptop needed for field work.
Great purchase, love it.

Philippe | Nov. 6, 2020

Not accurate, can't be used...

For 3DPrinter Filament Diameter Width Sensor Assembled

Impossible to use it, the same filament can be measured from 1.60 to 1.84 !!
Contacted the seller, he told me to add 1K resistance to have a measurement between 1.71 and 1.79, but it solve nothing.

Doing more tests with an oscilloscope and explaining the problem to the seller, he told me it needs to change the processor !

This device is completely UNUSABLE, don't spend your money on it.

Not a real product yet

For SMD Reflow HOT Plate Controller

The PCB seems to have missing components, at least an amazing amount of blank component pads. No mounting holes in the PCB! The schematic in the manual seems to differ from the received PCB. As it is, this product causes more trouble instead of solving an issue. I'm dissapointed.

Hi

I am sorry that you feel disappointed. The board is supplied as a basic hot end controller. it has extra features which are not yet supported. Mainly

Accepts 2 mote sensors
reset switch
buzzer control
fan control
Thermocouple support -

If you wish these features just drop me an email and I will be happy to supply you with a board with such features after I implement them in software.

Works fine, but documentation sketchy

For Classic 70's Pong Game

The finished product works nice and reliably.

It was difficult to get there though, documentation was incomplete and inaccurate. The PCB has many more places to solder parts than parts that were actually delivered, so I had to work out what goes where. Also part names and values were contradicory in different parts of the documentation, partly corrected by hand, partly not accurate. Bits of the features on the PCB were not explained, like old vs new solder bridge.

Great value for the money!

For Reflow Oven Controller Universal Board Ver 2.01

Had some issues getting the temp sensor working, which I'm now guessing had to do with grounding issues in my oven itself. The kit itself is great, the user interface is simple and intuitive. The documentation of wiring could use an update and I couldn't find the source code anywhere.

But the kit works great if you just want to reflow some boards. I made a 3d printed stand and mounted the controller on the oven itself. You can find the mount here- https://www.thingiverse.com/thing:3797144

Works good for a DIY Sensor

For 3D Printer Filament width Sensor PCB Kit

I ordered just the Kit because I do a lot of soldering for my projects. But mostly through hole components.
But like in the manual the soldering of the LCD chip is very easy. I didn't expect it to work, because it seemed like no solder was going under the chip. But it works.
Soldering the SMD capacitors I was a bit fooled by the pictures on the product page. First I soldered them in the through hole place.
Also it wasn't very clear how to orient the ATiny85 chip. This should be documented better in the instructions.

First I printed the case in red PLA. It worked by daylight was interfering with the reading. Also I printed the Remix version of the top to fit PTFE tubes and fittings. Now that I printed it in pure black the sensor seems less affected by daylight.
It took me also a while where to put the shutter from the print (didn't notice what that part would be). Here also would help a description in the manual.

The sensor is connected to a Bigtreetech SKR1.3 board. This can only handle 3.3V on analog Inputs. Since there is now Filament with more than 3.3mm diameter it would be cool if the output is limited to 3.3V. My board I protected with a 3.3v zener diode.

Thank you for this design.
I'm printing now for a while with crappy PLA (1,7-1,9mm diameter) and the prints turn out good so far. The live adjustment looks also very good.

Jose | June 7, 2019

Good sensor

For 3DPrinter Filament Diameter Width Sensor Assembled

It is a little difficult to connect to the GT2560 board. You must to do a weld and it is not so easy. You must also know the board pinout to select the proper pin and assign it in Marlin.
Then a better info from the seller would be very useful for the user.
The device runs perfectly and it is a good option to forgive the filament width issues.

Anton | April 2, 2019

Good item.

Working as intended

For 3D Printer Filament width Sensor PCB Kit

I was initially apprehensive about soldering the tiny little sensor onto the board but it turned out to be really easy as the instructions were clear and helpful. Aside from some slight confusion with the SMD capacitors with the extra through holes, which turned out to be a blessing in disguise ( I am really bad at SMD ) it all went together. In total, 4 kits were purchased and assembled by myself and a friend and we had 100% success rate.

As to whether or not it is improving my print quality.... That isn't really the point.

Brian | Nov. 9, 2018

Good concept, but QC issues.

For 3DPrinter Filament Diameter Width Sensor Assembled

I bought this a while back and just now getting around to trying it out. Instructions needs to be improved, especially when using with the supplied LCD board. The main gripe is the path for the filament, it is too small. I barely got a 1.5mm rod through the guide. When you pay a good price for this, the product should be tested before sent to the customer. Yes, they give you the stl file, so be prepared to modify and reprint the filament guide piece. Also when buying the kit with the LCD board, there should be a header that would connect the sensor to the LCD board (with a voltage regulator for the 5V sensor).

1 st board failed immediately.

For 3D Printer Filament Joiner/Fuser PID Controller

1st board failed immediately. Absolutely followed the included instructions exactly (very easy to hook up). The LCD lite up and started the count down, then a puff of smoke and it died .Contacted Jason on July 20th who said he would replace after testing his on hand stock for two days. It is now 8/16/2018. The replacement Jason claims he sent out has still not arrived. I will give a complete review after I receive and test the replacement
