Thank you very much for the kind words. I appreciate it. I have a lot of fun with the Hackerboxes, and I hope that you do too!

By any chance has anyone played with the Logic Analyser code? It is producing weird results for me.

And now I have done some playing around with programming the attiny85 to burn it as a digispark. Good fun!https://youtu.be/0XMc6szWnSs

Nice collection of bits. I have started into stuff and my progress so far is (mostly) in this video.Right now I am working on burning the micronucleus onto an attiny85.I did notice on my box that the CJMCU did not have blink loaded onto it. I think mine had the neopixel code, but now I will never know :-(.

You're welcome.

Makes me wonder how small a gps antenna can get....."The Pulse W3011 is only 3.2 (w) x 1.6 (l) x 1.1 (h) millimeters (mm), and it weighs just 0.033 grams, yet has an efficiency of 80% with an operating temperature of -40 to +85 degrees Celsius. Ground clearance area is 4 x 4.25mm"OK. Very small. So the limiting size on your tracking device is the battery (unless you use a supercap) and the SD card (unless you use the SD chip directly on a board and use pogo-pins to get the data off) in which case we are talking about on the order of 5x10x3.=Trust nothing! It is all tracking you!

This makes me curious about how small a GPS antenna can get. Or, how small a tracking device can actually be made. They fit into a phone, but what else?

u-center version 8.16 runs under wine. But you have to ln -S /dev/ttyACM0 com1

This makes me wonder how small a gps antenna can get. I mean they fit into phones....http://www.acalbfi.com/uk/articles/articlesContent...So, 1cmx1cm. The battery will be the largest part of your tracking device unless you use a super capacitor or something like that. And good power management.....Trust nothing!

if you have not heard the embedded.fm episode where they interview Addie (@atdiy) and Whisker (@whixr), the Toymakers (@Tymkrs) it is well worth a listen. http://embedded.fm/episodes/205 Addie and Wisker made the conference badges for https://cyphercon.com/cyphercon-20

If you are looking to make an 18650 holder, here is an instructable I did a while back. https://www.instructables.com/18650-Holder-From-PVC-Pipe/

So I put a bootloader on the atmega238P and made a video about the process. Thanks again to HackerBoxes for some fun parts and good hints as to what direction to move in. If you need more step by step, this video might help you.

Try going back to powering the device from the Arduino. It took at least 20 minutes for the sim to register on the network and for texts to start flowing for me.

I don't think you need the + in front of the country code. At least I did not.

What about under voltage protection in the device? You can ruin a lipo by letting them discharge too far.

You might also want to add some protection circuit to the battery. Like one of these:http://www.ebay.com/itm/5A-PCB-BMS-Protection-Board-for-18650-Li-ion-lithium-Lipo-3-7V-Battery-Cell-1S-/191995736230?hash=item2cb3d670a6:g:MNoAAOSwzaJYANqY

Nice. I made one along the same lines as you did. Aeroquad flight controller with the same motors.http://youtube.com/user/grtyvr

Thanks.

I will add telescope to the title. Thanks.

Link to a source for the usb stick movie camera? Those things look cool!

Try a couple of 10K pull up resistors, one on each of CH_PD and GPIO2. Also, if the serial port can not deliver enough current you might want to try to power the ESP8266 from a separate power rail.

Brilliant! Things like this is what make this site great!

For anyone on Linux (I have Ubuntu 14.04), u-center8.16 will run under wine, but you need to map the serial ports (COM1, COM2, COM3 etc) to the linux usb devices with ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com1I needed to get up to com3.

Saving scrap in the garage sometimes pays off.

Thank you.

Thanks!
