$50SAT the PICAXE powered PocketQube satellite has recently returned home, as you can see if you try to track its current location; http://www.satview.org/?sat_id=39436U With a de-orbit window of 2 hours, we have no idea where its remains ended up. It was fun. There are now no PICAXEs in...

The TUPOD launcher came out of the International Space station on Monday as planned and after the required 3 day delay, the Tubesats were ejected and the TUPOD beacon went active. https://www.gaussteam.com/tupod-almost-ready-for-launch/ The TUPOD launcher has a PICAXE powered Morse beacon and...

If anyone is going to Electromagnetic Field next week, I will be there giving a talk on the Worlds first PICAXE powered Satellite. https://www.emfcamp.org/about https://www.emfcamp.org/line-up/2016/101 LoRa will likley get a mention at the end of the talk too, its not been tried in orbit...

Michael Kirkhart, KD8QBA; Tuesday, July 21, 2015 marked the 20 month anniversary of the launch of $50SAT/MO-76/Eagle2, and unfortunately, it appears to have gone silent. The last time I heard it was on Sunday, July 19, 2015, 08:42 UTC from Anton's (ZR6AIC) WebSDR. A screenshot of the WebSDR...

I have been trying to get a definitive answer as to whether you can apply ‘self-certification’ to an electronic product that includes a transmitter. You may have seen my various posts on the LoRa transmitters, and there is potential for a marketable product there. However it’s not clear if...

There are quite few cheap TFT LCD Colour touch screens appearing these days in the 2" - 4" sizes on eBay. No doubt because they are manufactured in such large volumes for modern mobile phones. Does anyone know if there are any that can accept serial (RS232\TTL) input as a means of using these...

Well it darn works, ought to after all the testing. You can see where its getting to here; http://tracker.habhub.org/ Currently 110km south of Paris at 8000M. The temperature is being reported incorrectly (it has a -128 offset), but the real temperature at altiude in the dark is down to...

Version 2 of HABAXE will be using a RFM98 transceiver, this uses Semtechs new SX1278 LoRa device. The device is similar in size and capability to the RFM22B. It can generate FSK RTTY too but the LoRa telemetry from the Semtech device has much greater range than the FSK data telemetry produced...

This is a demonstration of the use of the Dorji DRF1278 wireless transceiver module which uses the Semtech SX1278 LoRa device. The PICAXE code should work with other modules that use the SX1278. The program will run on either the 40X2 or the 28X2. The Dorji module is is a bare module similar to...

One of the things I had been experimenting with in 2012 was using a PICAXE and RFM22B as a balloon tracker. I built a tracker that was light enough to use party balloons, heavy payloads need large balloons and lots of expensive helium (or hydrogen!). Small balloons are low key, simpler to...

I have been working on HABAXE, my take on a PICAXE based high altitude balloon tracker. The UK High Altitude Society (UKHAS) have a very well organised method of tracking high altitude balloons (HABs) whereby a lot of listeners co-operate by connecting their stations to the Internet and the...

I built a portable receiver for $50SAT so that I am not tied to a PC for listening for packets. For field use the received data can be directed to a PC file on a Micro SD card via an OpenLog Logger. However, Micro SD cards are hardly ideal for field use and I would much prefer to send the...

$50SAT (Eagle2) a PICAXE powered micro satellite was successfully launched from Dombarovsky Air Base in Russia this morning at 07:11. It should have been deployed by now at an altitude of 600km. As far as we know this is the lightest satellite ever to be put in earth orbit at circa 210g...

I have been looking at the Dorji DRF4463 as a replacement for the Hope RFM22B. The new Dorji module uses the Si4463 versus the Si4432 used in the RFM22. The newer Si4463 transceiver claims an extra 5dB of sensitivity at low data rates over the Si4432, so that should make line of sight...

Because its a product that uses a PICAXE. There has been interest in the Lost Model Locator I did, its small, not too expensive parts wise and has a variety of detection options. If you have access to HAM radio gear the tracking range for the GPS co-ordinates is just silly. Its a while since...

The attached picture is my portable LCD display, its used for the reception and display of data from RFM22 data packets. There is a single cell Lipo in the box and a small 3-5V up converter powering the LCD so that the contrast stays constant as the battery ages. The unit contains a PICAXE...

This is my take on a lost model locator (LML). Documents and plans will be found here; https://www.dropbox.com/sh/ompujkefda543w6/NXgepgXrmW There are two documents there; MK3 28X2 Lost Model Locator Information Draft V1_0 (explains how it works, is put together etc) MK3 28X2 Lost Model...

This is a circuit primarily designed to prevent Lithium Polymer (LIPO) batteries from being over discharged. I have a few LIPO batteries, they are used in a lot of RC models these days. A 3 cell LIPO battery puts out a voltage of 12.6V fully charged and are quite handy for powering battery...

This is the PICAXE code for an RF Beacon, actually the PICAXE in SPACE code with mission specific stuff removed. The code is for a PCB that uses a 40X2, but should run on a 28X2 also. The objective was to see if it would be possible to produce a small low cost satellite using commercial...

Here is my program; main: w25 = 65535 w26 = 65535 w27 = 65535 In the simulator w26 is displayed as 655535 $FBFA ? PE 5.5.5
