- I woke up this morning to a weird buzing sound, only to find that it was my Radiascan Radiacode 101 that I left plugged into to my PC overnight, and it wouldn't boot up. This is a partial teardown as well - as it shows how a battery might be replaced.
However good news, I found a simple way to fix it.
Later I updated it to 1.05 - Věda a technologie

My Radicode 102 died too. Wont power on or run on external DC. Took it apart and my battery was 0V. Gave the battery a quick taste of 3.7V(out of circuit) and then reassembled and recharged. It works! Thanks for the tutorial, these things are thankfully easy to open up without breaking the case. Great video! Well see if my battery lasts or if its permanently damaged.
Glad to hear you had success, 0v usually means the bms cut off the cell, also known as sleep of death. There is a tiny chip hidden in there. Those cells are not impossible to find
if the voltage went completely flat it will definitely shorten the life span but these devices draw such little amps or mAh that the battery won’t be in serious demand. I’d probably see if i can install a bigger battery (mAh) same voltage (4.20v) fully charged
@@anthony445 yeah these batteries are not hard to find, one feature I do appreciate about the radiacode
Other wise known as a hard reset, did you do the hold power button down for 10-20 seconds before opening?
Yeah I did all the usual things. I've been cutting videos a bit shorter lately, as people abandon most of mine 2 minutes in.
The problem is related to the extra usb-3.0 pins. In certain situations a signal similar to the device programming signal may occur, and then the device enters DFU mode. The only way to get it out of this mode is hardware reset, which is performed by disconnecting the battery.
I gathered it was something along those lines. Similar to digispark units where you interrupt the boot cycle to get them into rs232 mode.
You’d think the DFU would time out and it would return to the standard boot-loader. Good to know tho!
@@JamesReedy something for future firmware updates I guess. I contacted them about it, they seem to be aware of the issue
@@TheAussieRepairGuy if you’ve got their ear ask them why they haven’t released the iOS software. It’s apparently in Beta but I talked to Sergey in Feb of 22 and he said he expected it to be done by the end of the month 😐
@@JamesReedy i don't have any kind of direct l8ne to them other than the same email everyone else has. From my limited experience with IOS, the constantly shifting security and licencing rules with it, make it hell for 3rd party developers.
Odd request - Do you happen to know what that connector type is on the battery. Broke my doing an emergency battery pull due to water damage. Thought it would be standard but it is killing me trying to locate it.
I'm not sure, but if you have a small enough soldering iron I'm sure you could attach battery directly to the underside of the board, or fit a similarly sized plug and socket.
I'd suggest is may be a JST ACHR-02V-S, or maybe even a Molex 78172-0002,
@@TheAussieRepairGuy Thank you very much, I'll give those a try and resort to soldering it if that falls through. Really appreciate the reply!
those connectors are what they use on tiny whoop drones. Yes JST or some kind of molex. Pin spacing is a thing when looking for connectors so make sure in spacing is correct.
I hear quite a bit of background radiation. Is that showing 0.04 μSv/s at the end? That's 2.4/m. What source do you have nearby to get such a high level?
Thats normal background for this area.
Maralinga nuclear tests had an impact on a very large part of Australia.
@@TheAussieRepairGuy Wow, that's about 15 times as much than what I'm used to. You get a lot of ticks for your money there 😆
@@Ni5eiA normal geiger counter is much more quiet, most of that will be beta, not gamma.
there is a little bit of uranium glass in the display unit on my desk though.
but it's not very hot.
gamma usually gives me 0.15 micro sieverts/hr, pretty normal here.
0,04 is super low. I have 0,09 outside and 0,15 inside where I live.
Have a similar problem with mine - won't turn on aftar about 2 months of non-use (wasn't plugged into USB - worked fine when I put it away.) If I plug it into a power supply, the blue light lights up, but after 20m or so the power button still doesn't work. Did the hardware reset (left power connector off for ~3m) and no luck. Held button down for 30 seconds - no change. Any other suggestions?
You could try the same trick I did here.
The battery however might have gone into sleep of death - and might need a jump start.
Does it fire up when trying to start it while on charge?
I jump started a gopro battery a few years back - same process:

@@TheAussieRepairGuy Yes, I tried disconnecting/waiting/reconnecting as you showed. No joy. It won't start while on charge, though the blue light is lit. I've sent in a note to Radiacode - it should still be under some sort of warranty as I only bought it in late September.
@@johnhtodd One would hope at least. if you have another lithium pouch battery of the same voltage, that you know if good, you could try that.
@@TheAussieRepairGuy They replied to me and said: "Connect to the charger, wait a little bit, disconnect the charger and connect again, the charge should go." But that didn't work . What finally got it back going again was holding the right button (with the screen "up") and the round button at the same time, and plugging in the charge cable. Then it came back.
@@johnhtodd handy to know, I'll write that down.
Would you be able to put waterproof PCB coatings on the sensor (nailpolish, clearcoat whatever) looks good for the PCB, I am ordering one and am going to water proof it and haven't got a good look at it yet..
Not sure, most coatings are likely to affect beta readings. Try a ziplock sandwich bag, thats all I do. Makes it easy to decontaminate too.
@@TheAussieRepairGuy Hmm maybe, i'll put vaseline/dielectric grease on the sensor (or just the contacts) to be safe and coating on the rest. Good idea with the ziplocs will also use those for contamination.
@TheAussieRepairGuy doesn't it just detect gamma so beta wouldn't be detected also on the battery half is that a thin bit of lead (the gray part that is in the way of the crystal)
@@The-One-and-Only100 Alpha no, beta yes, and that isn't lead.
@@TheAussieRepairGuy so what is it?
Someone (on your comments I think) let me know that they’re shipping out of Cyprus now 😄
Ahh they did find a way around that. Still no reply to the email.
They are indeed relocated in Cyprus and are registered as a EU company. I bought a 102. Loving it.
Ordered the 102 today, yep shipping from Cyprus
Also if anyone cares I ordered my 102 on Monday and was delivered on Thursday in the center of the USA in Iowa.
@@brianhilligoss good to hear people are still receiving them.
Gotta say it’s remarkably non janky looking inside.
yeah I was pretty impresed too
