Thread: Intermittent Throttle Mystery on Spektrum 1S Indoor Receiver
08/12/2019 09:02:47

I check my 1S cells under load. To make a simmple battery checker all you need is a digital volt meter module( less than £2 from China, a push to make switch and a 4.7 ohm resistor. I described this in a letter to RCM&E a few years ago. Failling cells will show 4.2 volts when fully charged, but the voltage collapses under load.

Thread: source of 2mm Depron?
29/10/2019 22:15:50

Dear Ray, If I sent you a box of 360 x 800 x30 mm could you put the depron in it and post it back to me? I would of course pay postage, and for the depron. Thanks David

Thanks to all who have ofered advice. I have ordered some aero depron and will try cutting 6mm white down with a hot wire. It largely seems that I have missed the boat for 2mm white depron ,which is a shame as I have built 3 Fockers and 5 Chipmunks out of it,and they fly well. Plans for the Focker will be published in our club magazine shortly! The vector board seems heavier and more floppy, but also more resillient.;However for indoor flying lightness is everything.

I have been making models for indoor flying out of 2mm Depron. Recent internet searches for more supplies have been fruitless. Does anyone know of a good source of 2mm depron. Preferably in the UK. Thanks ,David

Thread: The Bolt chuck Glider
16/09/2019 09:24:30

I straightened the wings of my Lidle glider that I converted into a twin motor plane by cutting part way through them then filling the v with PU adhesive( Gorilla glue type of thing). Held it all down flat ,clamped to a board while the glue dried and it has worked a treat. I suggest some masking tape under the glue line to make sure it does not get stuck to the board! David

Thread: Transmitter / receiver issues, help needed pls
24/06/2019 16:46:21

Daire, Do you know the brown out voltage for your receiver? 3.7 volts seems rather low for a receiver supply .However you say 2s. if that is a lipo that gives 7.4 volts which is high for many servos. I hope your new esc will give 5 volts which is fine for most receivers and servos.

If you PM me your address I am happy to send you hard copy of the plans and article. David

Thread: Build your own telemetry sensors.
26/05/2019 17:47:24

Thank you all for the help ,especially Andy in this instance. I can now see all the cells and the total. My current sensor arrived yesterday so I will add it. I think for the air speed sensor it may be as cheap to buy the Frsky modulle,even if that seems like cheating!

26/05/2019 09:36:50

Chris and Mike, Thank you for your help. Sorry to be confused by the Frsky/arduino nomenclature. I now have a module almost working for lipo voltage. I have the following display on my Taranis X9D;-

1: A2 11.1V( presumably from the receiver)

2: Cels 11.49V

3: RSSI 84dB

4: RxBT 5.0v

5:Vfas 11.50V

I only have 3S lipos and have not yet built the current sid eof the modue.The arduino pin connections are as per Chris's diagram/ PCB. VFas_SOURCE VOLT_3 to use the balance lead. Why do I not have individual cells displayed ? Also I have a series of flashing stars on the transmitter display.Why?

Thanks for the project I am gradually getting my head round it. One last question is there a cheap airspeed sensor available?

David

Chris, isn't A4 used for SDA in the I2C bus. David

Thread: Lidl XL Glider

Thank you Steve, My store will be the 23rd too.I will be there! David

Steve, How soon is soon? Last time when there were gliders Lidl had sold out by the time I got there.Thanks

Thread: Build your own telemetry sensors.
15/04/2019 09:36:55

Chris,I am watching this tread with interest.I have read the"H" files but not yet tried programming my Arduino . I would be interested in two pcb's.

Thread: Amber with a frog in her throat
02/04/2019 16:54:11

I have poured cough mixture into my Taranis and Amber has lost her Dakek speach. Seriously though I had the odd speach with my Fun Cub selected,I moved to my Acrowat and the speach improved .I went back to the Fun cub and all is now fine. I am at a loss to know what was wrong but it seems to have righted itself! Thanks to all who offered suggestions as to the cause of the problem. David

01/04/2019 21:53:21

Chris, The sound files sound fine when played on a PC. They also sound OK when played in my friend's Taranis which is running 2.2.2. Should I try to go back to that?

01/04/2019 15:52:57

I have tried two different SD cards but the problem remains the same.Thanks for your input David

01/04/2019 11:02:14

I am running open Tx 2.2.3 no heli multimodule and the Amber sounds 2.2.3 on a Taranis X9D.(not plus) The initial greeting and switch warning is fine but the Amber sounds and telemetry warnings sound like a "Darlek" and are very slow. I have reloaded the SD card and the firmware to no avail. I have also checked inside the Transmitter for any lose wires. Does anyone have any ideas what to do next? Thanks David

Thread: Vector board
24/02/2019 16:35:56

Has anyone used Vector board foam? It looks interesting.Tough like epp and fairly light ,but heavier than Depron. It is avauilable from several model shops. I am thinking of buying some but am slightly concerned about its weight.

Thread: PIC Programmer
06/02/2019 11:10:44

I would agree with Robert and suggest starting with an Arduino. PICs are fine but you need a programmer, and to make life easier, a compiler to translate from a language like Basic or C to machine code. The learning curve is much steeper than for an Arduino which is very well supported both by the official site and loads of projects on the web. Even if the mini pro board is slightly bigger than a PIC chip it contains so much more such as Ato D converters and voltage regulators.The uno is a favourite starting board but the Nano is smaller and will do much the same-it is also slightly cheaper. What you can do with Arduinos is maily limited by your imagination. They are fabulous in my opinion.

Thread: Ideas for articles in RCM&E
28/01/2019 17:30:30

I very much agree with Phil. There is a place for electronics in rcn&E . Thre have been lots of threads and useful articles about crashes caused bt Rx battery failure. I have a arduino based checker which will measure the internal resistance of battery packs and their capacity. I have had some very interesting results which show how dificult it is to measure how discharged ,or otherwise a receiver battery is. These micro computer boards are rediculously cheap and there are lots of people who can help beginners to master them.
