Here.. :) It may work? I bought a small can of black paint for vinyl and plastic at an auto parts store when I built my last computer and needed the DVD drive to become black. It worked great and took very little time or paint. Just thinking, could this paint be used to turn a white cap into a blac...

Did a full Frsky telemetry, Frsky, SP prog board,controls led backlight, spesker and haptic build. Took a while to do it but it all works. Question for Mike regarding the Hub telemetry data displayed. Does er9x display data from all the hub on the display screens somewhere? I see A1, A2, one temp a...

SM: 1N4001 should be fine. Rob: This is to use a different supply voltage for the haptic drive, so needs the extra diode. Mike. Yes/OK to everything. I asked also because of the er9x haptic mod being for the most part external. I just realized I'm pulling 300Ma from that 78L05 regulator so I'd bett...

Re 1n4005 diode shown in haptic options. I have many 1n4001's and their peak reverse voltage is 50v where the 05 is 600. Should I buy some 1n4005's? I used a 1n4001 on the er9x haptic mod never giving a thought?

Re 3 ways to power picture,
I'm adding this to my notebook. Thanks

FYI FlySky /Frsky module interchangeability concern. If you want to reuse the Turnigy or FlySky original module you'll have to do the same pin isolation on the stock modules after you do the txd rxd mods to the TX per Mike's great circuit mod. The pin we use on the modified DJT for RXD out, TXD into...

Ok on all my answered questions. Now we all know more, thanks. Yes as far as the tx battery voltage used and the disapated heat due to regulating higher battery voltage. Same for the max current draw. I figured out up front that if another voltage source was used for the haptic device more current c...

Ok another haptic question(s). What is the max safe current that can be drawn? I never gave it much thought but I know the transistor and 3.3v regulator will have to supply the current. I see a resistor in circuit that may limit the max current but what about taxing the 3.3 volt regulator? I hate to...

Haptic fixed! Sorry for the Alarm" that it wasn't working. I forgot to go to the radio setup screen #2 and turn the haptic strength value up from 0 to 5. I'm good, it's good. Another question for later. with all the ram and cpu headroom is there a max model memory greater than the 16 we're used...

I just installed the latest update, r51 with the haptic option added and reconnected my haptic device. The motor no longer runs so I know it’s all talking to the update. I see the haptic options in the radio menu. My questions, It there a way to force the haptic feature to work without using a recei...

HobbyKing White Backlight Info ersky9x follow up. I checked my original notes that used a 5.0v source for the HK BL and the total drop with my meter across the black and red with 150 ohms (internal 50+150 external=200ohms) was 2.74v or 1.37 v/led. This is close enough for selecting your own external...

Re HK BL resistor. For my white LEDs I did measure it all when I installed it but my notes are at home and I wanted to get this posted ASAP. I'll open up my tx and measure the min and max tonight. Using the new tx super voltage and current display I show 114 ma BL off and 124 Ma with the BL on. If w...

My "current" Hobbyking backlight solution. I did some quick math to add a resistor in the BL red lead. My board has the 2 100 ohms in parallel so I end up with 50 ohms. Using  a led drop of 1.3v for white leds x 2 =2.6v. Take that from 5 volts max available and that leaves 5-2.6=2.4v to dr...

Welcome Florida. You'll enjoy the knowledge ride here for sure.

Beta thread it is.

Trying to do the right thing posts? I'm trying to sort out what and where to post questions vs progress or work arounds. So some help please.  The ersky9x questions thread I think should be used to post question about all hardware and FW installs or fixes? I quote Brent "Hi,  We can use this ar...

Thanks Mike, this info is what I hoped was current. If you or SkyNorth could comment, Now that the CPU temp can be read is there a value to be concerned about? The LA summers can be 110+f outside air temp. Never gave it much thought but it can't hurt to check it this summer. Also, for now if the mix...

I believe with r44 the trainer function may work now? I'll give it a try today on the bench. Just trying to do some beta testing as much as I can as the FW evolves. I'm assuming that the ersky9x boards PPM line doesn't load like the 9x board did with certain modules so no 1k resistor mod? I realize ...

FlySky module caution Some things worth mentioning. First I opened one of my two FlySky modules  with antennas attached to map pin outs and found that the coax shield solder joint at the module was no longer soldered, cold joint hanging free. I think. It's worthwhile to open your module and double c...

I finished all the mods tonight and just loaded r44 and I'm enjoying the new audio alarms. The current measurement is pretty neat. I read that the haptic code has not been added yet. I did wire it all up and it does send some voltage full time to the connector so I disconnected it for now and will w...

Any version will work for you that you can find in stock as long as it's the 9x model. The Smartieparts programmer work with either version board but requires a little mod for the older board. The solder in option programmer works for all version if you can solder OK. The best option is to throw awa...

Backlight info. just to be clear about the HK white in my case. The hk bl when powered off of the 9.9volt battery as intended with a 470 ohm resistor supplied draws around 15Ma as I remember and is bright. The leds I believe are in series and require 3 volts at 20 Ma max to drive them. The new board...

Throtle stick warning fixes! Mike you nailed it! I hadn't set it to mode 2 stick config that is also option 2 in the menu. If you know, does Sam-Ba have config options like eepe does? I'm assuming no since eepe was custom written for er9x by Eraz and Sam-Ba is a commercial product. Ok on to updating...

Pat, The throttle is not set to reverse. I even tried it at full with power on. I'll flash the latest r43 update later snd try again. I hope it's not my hardware. I'll try reseating the throttle connector later as well. I don't know what features are working but I don't think the diagnostic screen i...

I get mixed up as to what thread to post beta stuff in, sorry. (Please define what goes where and I’ll be sure to do it.) I just installed my ersky9x board with r42 and did all the case mods and fired it up. Great news it thinks it’s an ersky9x and has sticks attached to it. I do however get a throt...

I like the two sided tape idea so I won't do any board trace cutting at this time. I see you and SkyNorth are here so I'll post this other question here. I'm making up a template for drilliling the case for the USB and SD chip, and earphone jack. Is there any reason to make holes for the com1 or com...

Yes, the Tx and Rx signals need to be swapped. This is what I did, just to the bottom right of the RN42. RevBmod.png Mike. Just to be sure Mike, the trace cut and jumper wires redirecting was done on the RN42 or the ersky9x board? I'm installing the 9x board in the FS case right now and want to do ...

Take your normal voltmeter and connect it between the +13V(Solar rail) and the + on the 9V battery. If you are only getting like 4 volts then it will probably work. Also check that the grounds are connected with your meter. Just hook one lead on the meter - and the other to the solar -. You should ...

I just added a picture of the back of the PCB, not sure where to cut. Just to be clear. Unlike the RS232 to TTL converter needed for the er9x telemetry mod, the Frsky module modded the same way just goes to the ersky9x com1 port since it's all rs232 now? Frsky is RS232 already, right? I'm glad I re...
