JDM Programmer won't work with 8 pin chips

I bought a JDM programmer from ebay. It has slots for 8 pin, 18 pin and 28 pin chips. It's not a professional model, it's probably home made. When I use Winpic800 in Windows XP SP3 it is able to successfully read and write to both the 18 and 28 pin chips without a problem, but not with 8 pin chips. They're not automatically detected like the other chips nor can they be read of programmed properly. I think it might be due to power , but I'm on a desktop PC, so I don't think it's providing less power than required, plus why would 18 and 28 pin chips work all right. It could be the programmer, but all the connections appear sound, plus the thing came with some smart cards that already contained pre-programmed chips, including two 8 pin chips, so you'd think that it must've worked at some point. As it stands I haven't got a clue what I'm doing wrong and I would really appreciate help with this. Thanks :)

How can I record over an existing sound chip?

I get several birthday cards or little toys that have sound chips inside with a prerecorded message.  The board looks simple but I can't figure out out to re-record my own sound onto it.  Most of them have a big black plastic dot over (something).  Does this make it impossible to get to the actual chip/program? (Yes, I know I could BUY one -- I want to repurpose the several I have).

Posted by Popstickal 8 years ago


Hi Sorry for the bad English, hope you understand what I'm after. I've been searching the site for a kit that memorizes. Lets say you got 12 different buttons and 3 tactical buttons, when I push First Tactical for, lets say 3 sec. it goes into "write" mode, and now I make a combination of pushes on the 12 buttons, when done press the tactical again and now the combination is stored. And repeat with the remaining two tactical. Now I got 3 Tactical with different press Combo's.  When I'm in need of combo N#1 I just press the Tactical N#1 and it does the combo I've saved before. And so one if I'm in need of saved Combo's on N#2 and N#3. There should be a LED that tells me when I'm in "write" mode. Hope its not to confusing to understand, Its for my disabled little brother and are gonna be a great help for him and us. I will go in to further details if anybody has an idea on how to realize the setup Tnx in advance Best Regards Henrik Andersen

How a CPU is born

    While doing some research, I saw a link that said "How CPUs Are Made: From Sand to Silicon". Mildly intrigued and not knowing anything about how they are made, I clicked and went to the page and read.     The article briefly runs through a highly abridged series of steps in the making of what eventually turns out to be an Intel i7 processor. It starts off with the raw materials (SiO2, e.g., sand) and how they turn it into monstrous (about 220 pounds!), essentially pure, silicon ingots from which wafers are made. and many steps later the processors are boxed up and ready for store shelves.

Man injects himself with computer virus?

It may seem strange, but a scientist has implanted an ID chip with a computer virus inside it into his body so that whenever he passes an ID scanner, the virus will copy itself onto the scanner and spread throughout the system. It was made to prove a point that if somebody were to create a virus for the ID chipping system, it would be easy and could kill somebody if they had, for example, a pacemaker. A scary thought!

Impossible to identify microcontroller? Answered

So I took apart a remote control for a cheap helicopter. There is a 14 pin microcontroller on board. Unfortunately it looks like any other 14 pin IC out there and there are no markings on it. Is there anyway to identify possibilities. For example if I mapped where each pin goes on the PCB. Luke pin one goes to the LED's, pin 2 goes to the joystick, etc. Is there any way to "read" the chip to figure out what it might be?

Solid State Sensors? (Very Edited)

What properties of an environment can be measured with solid state sensors? Specifically, I am thinking of a project requiring a suite of sensors-on-chips that can measure their immediate (dry) environment and pass the data to a control unit.So far, I know of temperature, magnetism, radiation, acceleration and light (a camera chip).Are there any other (reasonably priced) solid state sensors, and where could I find them (either new, or reclaimed from something else)Edited:OK, so I thought I could be vague about my questions and then surprise everybody with a working satellite.Turns out I'm not so clever as I thought.I'm trying to recreate Sputnik on a tiny budget. Something that could be made by Joe Public, without having to rely on grants or Lottery funding.Sputnik weighed nearly as much as I do, but all it did was measure temperature and pressure, then send beeps that changed if the temperature or pressure went outside a certain range. I know it has been outdone by students with CubeSats, but they still cost tens of thousands of dollars.I thought that it should be possible to recreate (and out-do) Sputnik's capabilities on a single board, a simple programmable control chip taking in the data from a set of sensor-chips encoding it somehow, then passing it to a transmitter to be beamed to Earth.I thought - still thinking micro-budget - that the whole thing could be cased in a short piece of sealed PVC tubing, since PVC is radio-transparent.In my head, in fact, the satellite looks like a relay baton, but shorter.Am I being stupidly optimistic?

How to best touch up chipped ceramic tile on sidewalk? Answered

I'm wanting to touch up some chips on ceramic tile which is on our sidewalk.  The tile is different from the typical smooth gloss single color which you commonly see in bathrooms.  This tile has a bit of a texture and some speckles.  The texture (no doubt) is in place to keep you from killing yourself walking when it gets wet from rain etc...  I was dreaming of using some sort of opaque paint marker(s) and a perhaps some sort of epoxy sealant.  Maybe laying down some paint marker and then manually adding some speckles....   I'm using these terms loosely.  Any suggestions?  See picture of sample chip.  I put a quarter in the picture to give you some sense of scale.  You may notice some discoloration around the grout area - that's probably because I had just wiped the tile area clean with a wet paper towel.
