Comment List
  • Good tips and advise Wesley.

  • Since you were selected as a roadtester any posts from here will get emailed to you Angela.  Any updates/news or changes, this is a typical thing to happen when accepted into a roadtest.  Check the page STM Discovery Board for Makers  and you will see.

  • Hello,


    I have received this email in error; I’m not Tim, my name is Angela and the Element 14 road tester TamarB).


    This is the second email today along similar lines.


    Thank you, Angela

  • Well Tim,

                  I am sorry you feel that way I have been apart of the community for some time now and yes this will be my 3rd roadtest which I am excited for.   Now it is not about you me or anyone else.  The only one it is about is the supplier and their needs and what they want.  Sometimes what we want to do with a board or other item  listed on the roadtest is really not what they want so they go on to the next just because the project seems exciting new and fresh to you it might not be to them.


    Since looking at your profile you have just recently joined and have started posting and all in the roadtest here.  Start taking part in groups become a helpful and thoughtful member of the community before you start slamming something it just shows how ignorant and such a poor looser you are. 


    Using curse words in your response to those picked shows exactly why to me you where not chosen.  And as well it looks like you didn't submit your application correctly if you had done one.


    Now my apologies and don't mean to offend you if I have done so this far was not my attention.


    When I first started applying for road tests I was doing actually what Randall posted above really short blurbs and not going into description of any of my intent for the product.  I will use an example.   On a recent roadtest a user was given a product a really expensive product and all they did was basically take a few photos and wrote what was on the box.  Because really the roadtest page had more information listed about the product then their roadtest.  No actual test where done.

    So would this make a supplier happy?  would it make me want to buy the item?  would it make me want to continue to send e14 items for review.    Chances are all those are a no.   This is not what the intent of the program is for as they have people to do reviews on youtube and other social media but they want to allow for our community members to get involved with their product and review and discuss it.  So that leads me to the social media aspect the person was a new member with no posting found on any social media site at all.   Check my instagram youtube twitter facebook and website your gonna see me talking about my roadtests and projects that I have on the go with   Because really they could just send everything to Ben for review and scrap us. 


    So if you see where I am going with this great if your first response is "whatever".  Then that's fine too you can say whatever you like about but the users will just laugh at you because your statement is completely funny and not warranted.


    Just so you know I have applied for many roadtests and have only gotten a few. Sure it disappoints me but life goes on and I always have more projects ready to go.


    My tips for any NEW applicants is:


    1. Make sure to be detailed on your application and your intent for the device/product.
    2. Feel free to let the supplier know how they would benefit from you taking part in the roadtest.
    3. Be different.
    4. if you application is only 2 sentences or less time to spend more time on it.
    5. Remember they are giving you product for free (if it was something I made I would make sure its going to the right people)
    6. Remember there is more then one roadtest to take part in.
    7. Don't post your frustration about the decisions (gets old)
    8. Read those rules and check out the threads on making your roadtest.


    Now another think I would like to mention is when some road testers have completed their roadtest they are done with that board it goes back into the box or bag and sits there most are willing to trade or share their stuff.

    Along with their knowledge.


    I know this is a bit much to be posting in a road test spot here and if possible to have this thread cleaned up.


    There is no scam its equal opportunity here on the roadtests and its up to you to get the suppliers attention once its been passed on to them.


    I hope you take the time to look back and realize how silly your post there was on my comment as it was inappropriate and uncalled for and I didn't appreciate it. 


    So my final words, don't be discouraged if you don't get in the first time or 8 or 9th like me.  Learn from your previous applications and grow from there.


    Best of luck to everyone and hope to see some great roadtest reviews here on this board.

  • Hello Randall,


    I think the following email has come through to myself by mistake………….


    Kind regards,



  • Fake Scammer, is that not a double negative and therefor a positive image


    We pretend to be a scammer but were fake so really were good guys


    Thanks for that...


    But seriously, new comers are selected frequently for roat tests, and they often will post a good review, but often will also just grab and run, successful road testers are also selected for more road tests as the vendors like what they see and trust they can do it again, but at the end of the day, it is down to your APPLICATION, if you dont apply then you can hardly complain... stop trolling and try co-operating, you might like the outcome

  • Whatever, posting has been uploaded to Facebook and Youtube, fake scammers

    always the same people, 3 for sure.

    Don't contact me you guys are scammers

  • Tim,


    First off, I don't appreciate your foul language. State your opinion without resorting to expletives.


    I went back to the applicants. I do not see that you applied. Why not?


    Why don't you try applying and write a decent application and you will pop up to the short list of finalists.


    Roadtests are competitive. An applicant being selected a winner starts with a decent application. So, let's look at some applications. Here is what I get:


    Applicant 1. Not sure what you want here


    Applicant 2, I need to use the board for testing the possibility of the project


    Applicant3. j


    Applicant4. I would want to help road test this product by Seeing if it mets my companys standers


    Applicant5. I need to use the board for testing the possibility of the project


    Applicant6. Interested in helping the community while gaining exposure to products I may not be able to gain access to otherwise.


    Applicant7. I will be glad if selectred to test the product


    Applicant8. I want to learn how to develop PCBs.


    Applicant9. man there is a lot of room to write in here.  I'll just simply state you wont be dissapointed in allowing me to join in the RoadTest.   have a great day!


    Applicant10. I run a private industrial training institute with electrician trade.


    Applicant 11. nothing


    This is all they wrote, for heaven sakes!!! So, Tim, would you award the free kit to any of these 11 applicants above?


    Now, let';s look at the application of one of the winners (anonymously):


    Just about a month ago I backed the Librem 5 Phone developer kit ( to try my hand at developing GTK apps for the phone. When I saw this STM Discovery Board for Makers come across for Roadtest I was stoked! and thought of trying to build a phone with very basic features. My intention if selected for the Roadtest is to try out a couple of projects for which I will post as separate blog posts in addition to the Roadtest review.


    Project #1 – Build a basic phone – I have an Arduino GSM module(Seeed SLD01098P GPRS/GSM Shield V2.0) which I plan to use with a ting SIM card to build basic phone functionality, by taking advantage of the microphones on the board and hookup speaker to the audio jack. In addition I would like to add texting functionality using the screen on the board. Now I am not sure if the GSM module that I have will be compatible with the discovery board, so as a backup just in case I am not able to get the GSM module to work, I plan to use Twilio over wifi to achieve the functionality In addition, I would also like to add a feature to test connecting a USB web came to OTG connector to take picture and video and store it on a SD card, I have an old Logitech UVC camera handy for this. I had done a project a while back using a GSM module here is an image of the prototype, but with the Discovery Board the idea is to add a UI, you can read about this at -


    Project #2 – Posting sensor data to AWS IoT/AZURE , as part of this project I would like to test posting data via GSM so that I can make the whole module mobile and take it around the city to compare the pollution level at various spots, for this I have Seeedstudio Gas sensor, Air quality sensor and Temperature sensor handy.  Here I am going to try and use AWS IoT, and if the GSM module does not work then I will fall back on my wifi router. I have previous experience in posting data to both AWS IoT and Azure IoT.


    In addition, per the documentation it mentions that the module is compatible with linux 64 bit, so this means I will also provide feedback/my experience on this, as I have Debain stretch installed on my laptop and Ubuntu 16.04 on my desktop.


    Tim, this is a guy that has made an effort. He or she has demonstrated to me that he really wants to get this kit and do something with it. If an applicant puts this kind of effort in the application, she or he will be noticed.


    I always try to recommend new roadtesters to the supplier. If you have any more questions, feel free to contact me. I would love to have you participate in the RoadTest Program.

  • Quite true Mark but there's still another 52 applicants who may want to apply for the other road tests and could do with some hints on how they can do a better roadtest application and report.
